How Smoke Control Systems Work

Purpose

Introduction

The information in this guide serves to define the intended function of Smoke Control System
Equipment and also explain what operational and performance requirements are necessary for
equipment listed under the UL listing category of UUKL.

IMPORTANT: Smoke control systems must be designed to meet the custom

needs of a particular building and its occupants. This document

This product is subject to change without notice. This document does not constitute any warranty,
express or implied. Tyco Safety Products reserves the right to alter capabilities, performance, and
presentation of this product at any time.

Many people are not aware that smoke is the major killer in fires. Smoke can travel to places in
buildings that are quite distant from the scene of the fire, threatening life and property. It can fill
stairwells and elevator shafts, blocking both evacuation and firefighting. Smoke control systems
reduce the number of smoke-related injuries and deaths. In addition, these systems reduce property
loss and damage caused by smoke.

Smoke control makes use of powered fans to produce air pressure that can control smoke
movement. Air pressure has been used in laboratories for over fifty years to prevent airborne
bacteria and poison gases from migrating from one area to another. It has also been used to control
the entrance of dust and other contaminants into computer rooms; and used in hospitals to prevent
the migration of harmful bacteria into sterile areas.

This chapter gives you an overview of smoke-control systems, including a discussion of the
driving forces of smoke movement, the principles of smoke control, and the concepts of smoke
control system design.

illustrates some basic, common smoke control applications, but is
not in lieu of a properly engineered smoke control system,

Introduction

Design Parameters

Design Concepts

A smoke control system can be designed to provide an escape route and/or safe zone.
However, all smoke control systems have the following design parameters:

• Air-flow paths through a building and leakage areas.

• Pressure differences across smoke control system boundaries.

• Door or vent openings in the boundary of a smoke control system.

• Airflow through openings in smoke control system boundaries.

The following factors can affect the design of a smoke control system:

System Flexibility:

System flexibility means using features that allow for easy adjustment of a particular system to
meet the demands of a given situation. For example, during the design and construction of a
building, leakage paths can be estimated. Thus, a smoke control system can only be designed to
provide theoretical protection from smoke. After the building is completed, the system must be
tuned to the actual pressure values. System flexibility is also useful when retrofitting smoke
control systems in existing buildings.

System Control:

A smoke control system should be designed to automatically activate, preferably by an alarm from
a smoke detection system in the fire zone. The advantage of this type of activation is that the
system is activated in the earliest stages of a fire. Smoke control systems should be activated after
the receipt of alarms from a properly designed smoke detection system.

Energy Conservation Management:

Energy conservation methods must be considered when designing a smoke control system.
A smoke control system must be designed to override the local heating, ventilation, and air
conditioning (HVAC) system, or energy management system in order to implement the desired
smoke control operations.

Use of Fire Suppression Systems:

Many fire protection schemes use automatic fire suppression systems. However, while the
functions of fire suppression and smoke control are both desirable, they are not intended to
substitute for each other.

Fire suppression systems are intended to limit the growth rate of a fire. Smoke control systems can
provide safe zones and tolerable conditions along exit routes, but can do little to control fire. In
addition to the obvious differences between the two systems, the way the systems interact must be
considered. For example, pressure differences and air flows are different in the various buildings
within a complex that is protected by a fire suppression system. A water spray from a sprinkler
might interfere with air flow to a smoke exhaust or an outside air pressure system or a smoke
control system could interfere with the performance of a gaseous agent (e.g., Carbon Dioxide or
Nitrogen) fire suppression system.

A general guideline is that the gaseous agent fire suppression system takes precedence over the
smoke control system. It is also desirable that the smoke control system be able to purge the
residual gases and smoke after the fire is extinguished, and replace them with fresh air. This is an
important life-safety consideration, since some fire-suppression gases are asphyxiates.

Controlling Smoke Movement

Basic Concept

Second Floor

Regardless of the method, the basic concept behind controlling smoke is to use differences in air
pressure to minimize the spread of smoke and, if possible, vent it from the building.

You cannot confine smoke by simply closing all access ways (such as doors and vents) to the
room that has the fire in it. Even with these passages closed off, smoke can disperse throughout a
building via cracks, holes made for pipes and electrical wires, and spaces around doors and
windows. Smoke is driven through these small openings by the expanding gases from the fire.
Smoke can also be driven onto other floors by the “stack effect,” which causes air to rise in
buildings. The stack effect is caused by the difference in the interior and exterior temperature of
the building. The figure below shows how smoke can disperse throughout a building:

Controlling Smoke Movement, Continued

Basic Concept

Since smoke is carried by the movement of air, you can stop the spread of smoke throughout the
building by lowering the air pressure in the area containing the fire and by raising the air pressure
in the surrounding areas and floors. The difference in air pressure (also called the “Air Pressure
Differential”) between the smoke-filled area and the surrounding areas acts as a barrier to the
smoke, pushing it back into the smoke-filled area. The figure below shows how this works.

Figure 1-2. Applying Positive Air Pressure to Control Smoke

1. Lower the air pressure in a smoke-filled area by controlling the air flow into it and turning

ON the exhaust fans from the area to full capacity. This “Negative Air Pressure” technique
pulls the smoke out of the area and vents it outside of the building.

2. Pressurize the areas and floors surrounding the fire by turning OFF all exhaust systems

(including closing any exhaust dampers) and forcing supply air to those areas at full capacity,
creating zones of “Positive Air Pressure.” The air in the pressurized areas tends to leak into
the smoke zone, using the same cracks and holes that the smoke would use to get out. This
positive pressure airflow into the burning room keeps the smoke from spreading.

Basic Concept

3. Turn OFF the air inlets and air returns of the areas that are neither being pressurized nor
depressurized (i.e., areas far away from the fire). Turning OFF the air return prevents the
smoke that is being vented into the return air system from coming into the smoke-free area.
In cases where there are large openings (such as an open doorway) between the area on fire
and an adjacent area, smoke can be confined by a large volume of air. Pumping large
amounts of air through the adjacent space creates a constant draft through the opening into the
smoke zone (as shown below).

Figure 1-3. Confining Smoke with a Large Volume of Air

The draft through the open space keeps back the smoke, confining it to the smoke zone. The
amount of air required to keep the smoke from penetrating the open space is quite large. Avoid
this type of situation when possible.

Creating
Smoke Zones

To contain smoke by using pressure, you must divide the building into “Smoke Control Zones.” A
floor or several floors of the building can be considered a single zone or a single floor can be
broken into a number of zones. A zone must be separated from other zones by smoke dampers,
airtight doors, and smoke-proof barriers.

When a fire occurs, the smoke control system can then pressurize all of the zones around the zone
where the fire initiated (called the “Fire Zone”), isolating the smoke to that single zone.

If the smoke control system is non-dedicated, the layout of the smoke control zones should take
into consideration the layout of the HVAC system. You should place multiple areas served by the
same HVAC controls in the same smoke control zone. Also, the smoke control zones must
conform to any fire control zones that have been established, because the smoke detectors are tied
into the fire detection system. Also, keeping the smoke control zones and the fire control zones the
same makes it easier to coordinate the two systems.

Controlling Smoke Movement, Continued

Causes of
Smoke Movement

The following forces affect smoke movement:

Stack Effect:

When the outside air temperature is colder than the temperature inside a building, there is often an
upward movement of air within the building. This air movement is most noticeable in stairwells,
elevator shafts, electrical risers, or mail chutes, and is referred to as “Normal Stack Effect.” This
phenomenon is most noticeable in tall buildings during winter, but can occur in a single story
building as well.

When the outside air temperature is warmer than the temperature inside a building, there is often a
downward movement of air within the building. This air movement is referred to as “Reverse
Stack Effect.”

In a building with normal stack effect, the existing air currents can move smoke a considerable
distance from the fire origin. If the fire is below the neutral plane of the shaft (i.e., an elevation
where the hydrostatic pressure inside the shaft equals the hydrostatic pressure outside the shaft),
smoke moves with the building air into and up the shaft. Once above the neutral plane, smoke
flows out of the shaft into the upper floors of the building.

Buoyancy:

Smoke from a high temperature fire has buoyancy due to its reduced density. In a building with
leakage in the ceiling of the fire room, this buoyancy-induced pressure can produce smoke
movement. In a fire room with only one opening to the building, air flows into the room while hot
smoke flows out of the room. If the fire room has open doors or windows, the pressure difference
across these openings is negligible because of the large flow areas involved. However, for a
tightly-sealed room, the pressure differences due to expansion may be important.

Wind:

Wind can also have a pronounced influence on smoke movement within a building. The effect of
wind velocity on the air movement within a well-constructed building is minimal. However, the
effects of wind can become important for loosely-constructed buildings or buildings with open
doors or windows.

Frequently in fires, a window breaks. If the window breaks on the side of the building away from
the wind (the leeward side), the negative pressure caused by the wind vents the smoke from the
fire room. This can greatly reduce smoke movement within the building. However, if the broken
window is on the windward side of the building, the positive pressure of the wind can force the
smoke throughout the fire floor, and possibly to other floors as well. This event can endanger lives
and hamper firefighters as well. Wind induced pressures can be quite large and can easily
dominate building air movement.

Causes of
Smoke Movement

Managing
Smoke Movement

HVAC System:

Before the development of smoke control systems, HVAC systems were shut down when a fire
occurred. This is because an HVAC system frequently transported smoke during building fires.

In the early stages of a fire, HVAC smoke transport can be a good thing. When a fire starts, the
HVAC system can transport the smoke to a location where people can smell it and be alerted to
the fire (although they may not know where the smoke is coming from). However, as the fire
progresses, the HVAC system transports the smoke to every area that it serves, endangering life in
all those places. To make matters worse, the HVAC system also supplies air to the fire, which aids
combustion.

Although shutting down the HVAC system prevents it from supplying air to the fire, this action
does not prevent the movement of smoke through the supply and return air ducts, air shafts, and
other building openings due to stack effect, buoyancy, or wind effect.

“Smoke Movement Management” includes all of the methods that can be used to modify and
control smoke movement for the benefit of the building occupants, firefighters, and for the
reduction of property damage. The use of barriers, smoke vents, and smoke shafts are traditional
methods of smoke management.

Barriers:

The effectiveness of barriers in limiting smoke movement depends on the leakage paths in the
barrier and on the pressure differential across the barrier. Holes where pipes penetrate floors or
walls, cracks around doors, and cracks in walls or between walls and floors are a few of the places
where smoke can leak through a barrier. The pressure differential across these barriers depends on
wind, buoyancy, stack effect, and the HVAC system.

Smoke Vents and Smoke Shafts:

The effectiveness of smoke vents and smoke shafts depends on their distance from the fire, the
buoyancy of the smoke, and the presence of other driving forces. In addition, when smoke is
sprinkler-cooled the effectiveness of smoke vents and smoke shafts is greatly reduced.

Elevator shafts in buildings have often been used as smoke shafts. The obvious problem with this
is that it prevents the elevator from being used for fire evacuation (because of the “piston effect”
of an elevator), and frequently allows the smoke to travel between floors. Specially designed
smoke shafts which have no leakage can be used to prevent the distribution of smoke to fire-free
floors.

In summary, the effectiveness of barriers in a traditional smoke management system is limited to
the extent that the barriers are free of leakage paths. Smoke vents and smoke shafts are limited by
the fact that the smoke must have sufficient buoyancy to overcome other forces that may be
present.

In the last few years, motorized fans have been used to overcome the limitations of the traditional
systems. The systems that employ these motorized fans are called “Smoke Control Systems.”
These Smoke Control Systems rely on creating air pressure differences and positive or negative
airflows to limit and control the movement of smoke and other noxious gases.

Principles of Smoke Control Systems

System Types

Maintaining
System Integrity

Two types of smoke-control systems exist – Dedicated and Non-dedicated.

• Dedicated Smoke Control System: Is installed in a building for the sole purpose of
controlling smoke.

• Non-dedicated Smoke Control System: Uses parts of the building HVAC system to control
smoke.

In some cases, a building has both non-dedicated and dedicated systems. Non-dedicated systems
are used throughout the building for normal areas such as offices and manufacturing facilities.
Dedicated systems are used for special areas, such as elevator shafts, stairwells, stairtowers, and
other areas that need special smoke-handling techniques.

Smoke Control System products connect to HVAC equipment to form a system for controlling the
flow of smoke during a fire condition. Smoke-control systems are designed, installed, and
maintained so that a system remains effective and provides a “Tenable Environment” during
evacuation of the protected areas. A “Tenable Environment” as defined in NFPA 92A, is an
environment in which the quantity and location of smoke is limited or otherwise restricted to allow
for ready evacuation through the space.

A major concern with any emergency signaling system, whether burglary, fire, or smoke control,
is maintaining system integrity. This task is traditionally accomplished by electrical supervision of
wiring. However because the proper operation of the fans and dampers connected to the output
circuits may involve mechanical controls and pneumatic controls, as well as electrically-actuated
parts, end-process verification is provided. The end-process verification is provided to alert the
firefighter/operator that the fan or damper has operated in response to an automatic or manual
command issued during an emergency condition. While end-process verification confirms
operation during an emergency condition, system integrity during a non-emergency
(normal supervision) conditions is checked differently depending on whether the equipment is
non-dedicated or dedicated.

The operability of the non-dedicated smoke-control equipment is verified by the "comfort level" in
the areas that are served by the equipment. In other words, if the HVAC equipment is not
functioning properly, the building occupants are soon made aware of this and the problem can be
solved.

The operability of the dedicated smoke control equipment is verified by an automatic self-test that
is performed on a weekly basis.

Smoke Control and Fire Control System Differences

Separate System
for Separate Goals

The smoke control system is usually separate from the fire control system, since they have
different goals. The goal of the fire control system is to contain and extinguish the fire as fast as
possible. These systems, which halt the fire but not the smoke, are often triggered automatically,
relying on the heat of the fire to activate the system. Although smoke control systems are also
automatic, you must have manual overrides for the automatic controls.

A smoke control system may also be required to work with gas-based fire extinguishers, such as
gaseous agent systems installed in many computer rooms. If the smoke control system tries to vent
a room with such a system, it may vent the fire suppressing gas as well. Removing the gas lets the
fire continue burning. Also, pressurizing the areas surrounding an extinguisher equipped room
reduces the effectiveness of the system. Air forced into the room from the outside by pressure can
provide the fire with the oxygen it needs to continue burning. Therefore, gas-based fire

extinguishers and smoke control systems should not be active at the same time in the same
area.

The smoke control system receives the location of the fire from the fire panel. The fire panel uses
a combination of smoke and heat sensors to determine where the fire is located. As defined in
NFPA 92A: In the event that signals are received from more than one smoke zone, the smoke
control system will operate in the mode determined by the first signal received.

Specific, zoned smoke control strategies should never be triggered by manual pull boxes. The
risk of someone pulling a box someplace other than the fire zone is too high for you to trust your
smoke control system to this form of activation.

All smoke control systems installed in buildings must be in accordance with the standards
adopted by local codes. You can find additional information regarding fire alarm control units in

Underwriters Laboratories Standard UL 864 and the National Fire Protection Association (NFPA®).

Designing a Smoke Control System

Basic Goal

How to Begin

Engineering
Responsibility

The basic goal of the smoke control system is to maintain a tenable environment. A tenable
environment allows:

• The building occupants to evacuate safely from the building.

• The firefighters to get quickly to the fire zone.

The first step to take in designing a smoke control system is to lay out the smoke control zones,
as previously explained. After the smoke zones are established, address the following design
factors:

• The zone-by-zone smoke control plan.

• The amount of pressure needed to contain smoke.

• Proper separation between zones.

• The fans and duct work used in the smoke control system.

• Dampers required for smoke control.

• The air inlets and outlets used in the smoke control system.

Smoke control systems must be engineered by qualified personnel. Complete calculations of
system designs are the responsibilities of the Engineer of Record and go beyond the scope of this
publication. A high level of coordination is required between the engineers, Authority Having
Jurisdiction (AHJ), and system designers who are involved in the process.

Creating the
Zone-By-Zone
Smoke Control Plan

You must create a smoke control plan for each zone in your building. Each smoke control zone
plan consists of the number of steps the smoke control system must take to contain the smoke in
the building zone. For each zone, you must decide:

• Whether you should depressurize the zone if a fire occurs.

• If the zone is to be depressurized, by how much you should depressurize it.

• Which adjacent zones should be pressurized and how much pressure is required.

Some zones in a building may need special consideration. As mentioned earlier, zones that have
gas fire extinguisher systems should not be vented (depressurized) and the zones surrounding the
fire zone with such a system should not be pressurized. You may not be able to pressurize other
areas, such as hospital labs or biological research labs, due to the risk of contaminating
surrounding areas with germs or toxins from these facilities.

Consider the number of zones surrounding the fire zone that should be pressurized. While, in
theory, all you need to do is to pressurize all of the zones immediately surrounding the fire zone, it
is possible that smoke can find a way around the pressurized areas and infiltrate distant zones.
Thus, depending on the size of the building and the capacity of the smoke control system, you may
decide to pressurize more zones.

Note: An increase in the number of zones to be pressurized means a corresponding increase in

the size of the air supply system.

Make certain to write down the state that all fans, dampers, and other smoke control equipment
should be in to control smoke in each zone. Then program this information into the smoke control
system.

1-10

Designing a Smoke Control System, Continued

Determining the
Smoke Containment
Pressure

Since air pressure is what keeps smoke from spreading, the primary design factors are the amount
of pressure needed to confine the smoke, and the size of the system used to create this pressure.

For the smoke control system to create a barrier of air pressure between the smoke zone and
surrounding zones, the amount of pressure required varies with the height of the ceiling and
whether or not the building has a sprinkler system. The table below gives examples of the
minimum pressure differential needed to keep smoke out of rooms surrounding the fire site as
defined in NFPA 92A.

No 15 ft. 0.14 in.

No 21 ft. 0.18 in.

* in. = Inches, Water Gauge

Pressure buildup in an area depends on the amount of leakage. Leakage occurs through joints,
cracks, openings for pipes and wires, gaps between doors and their door jams, and so forth.
The better the zone is sealed off from neighboring zones, the easier it is to maintain the required
pressure. Since larger openings, like normally-open doorways, require large amounts of air to
maintain pressurization, you should avoid this type of situation.

Separating Smoke
Zones Properly

Selecting the Proper
Fans and Duct Work

You must separate smoke zones from one another by “smoke barriers,” which prevent smoke from
passing through them. Smoke barriers can be a wall, a floor, or a ceiling. Any openings in the
smoke barrier must be closed with a smoke-proof fitting. For example, any duct work going
through a smoke barrier must have “smoke dampers” installed. A smoke damper is a damper that
prevents smoke from passing through it when fully closed. During a smoke emergency all of the
fittings should seal themselves, so that smoke cannot penetrate the barrier.

Since the smoke control zones should be the same as the fire control zones, you usually separate
your zones with a “fire-rated partition.” A fire-rated partition is a wall that is built of fire resistant
materials and that reaches from floor to ceiling. Different floors should be separated by a “fire­rated ceiling,” a ceiling made of fire-resistant materials. Both fire-rated partitions and fire-rated
ceilings are rated for the amount of time they can withstand a fire. Any openings in a fire-rated
partition or ceiling must be capable of being sealed with a fire-rated closure, such as a fire-rated
door or fire damper.

The fans and duct work used in the smoke control system must be capable of providing the
amount of pressure you calculated earlier. In a non-dedicated system, this may mean that you
need to install fans that have a higher capacity than the HVAC system normally requires. The
ducts must be capable of taking the pressurization (or the depressurization, for the fire zone's
return duct) that the smoke control system demands. Both the fans and the ducts should meet local
requirements such as those stated in NFPA 90A, Standard for the Installation of Air Conditioning

and Ventilating Systems.

Continued on next page

1-11

Designing a Smoke Control System, Continued

Selecting the Proper
Fans and Duct Work

Choosing the
Proper Dampers

Fans must be capable of reaching the required pressure setting within 60 seconds. Each fan must
also have a pressure monitor so that the smoke control system can receive feedback on the status
of the fan to determine whether it is actually working. It is the responsibility of the system
designer to select duct work that meets the temperature and fire ratings for the specific application.

In some climates, the outside air can be so cold that drawing it directly inside the building for
pressurization can damage the building's interior fixtures or equipment (e.g., freeze pipes or
damage temperature-sensitive equipment). In these cases, some sort of pre-heater needs to be
installed on the air inlet. The smoke control system does not need to control this air intake heater
as closely as one on an HVAC system, since maintaining comfort levels is not an issue. It simply
has to make sure the air sent into an area is warm enough to not damage the building's equipment.

The dampers used to isolate the smoke zone must be smoke dampers. Smoke dampers are dampers
that meet the requirements given in UL 555S, Standard for Leakage Rated Dampers for Use in
Smoke Control Systems. Following this standard ensures that the dampers are able to block the
smoke when they are fully closed. These dampers may be different from those you might use in an
HVAC system that does not perform smoke control.

In a smoke control system, the dampers must be able to travel to their desired setting in a maximum
time of 75 seconds (see note below). All dampers must be fitted with end-position switches to
provide feedback to the smoke control system. These switches let the control system know the
position of the dampers, since smoke dampers are usually either fully-closed or fully-open.

Note: Local codes may specify a shorter maximum time.

Dampers sometimes function as both smoke dampers and fire dampers. Fire dampers are dampers
that block a fire from penetrating a fire-rated partition via a duct. These dampers are normally
open, held in place by a fusible link. The fusible link is a heat-sensitive device that releases the
dampers when it is heated to a certain temperature. Once the fusible link releases, the dampers
close by the force of gravity. This is required so that fire dampers operate even if the local electric
service has failed. The specifications for fire dampers appear in UL 555, Standard for Fire
Dampers.

If you want a damper to function as both a smoke damper and a fire damper, it must meet the
requirements for both devices. A damper can be operated by an electric motor or pneumatics.
However, it must have a fusible link or some other means of automatic closure (like a regular fire
damper). Since the control system can override the damper closure if the temperature warrants, the
damper needs the fusible link in case the damper’s automatic control is interrupted.

Placing Air Inlets
and Outlets

You need to carefully consider the placement of the air inlets and outlets on your building. If you
place an outlet that vents smoke too close to an air inlet, the air intake can draw the smoke back
into the building. Since smoke rises, the exhausts that vent smoke should be placed well above air
inlets. The exhausts should be placed several feet above the roof level to allow space for the
smoke to rise and disperse.

Keeping smoke outlets far away from air inlets does not guarantee that the air brought into the
building is always smoke free. You may want to place smoke detectors in air inlets that operate
during a smoke emergency.

Note: In some cases, smoke detection in the air inlet is required to have the capability of being

overridden by the responding authority after the situation has been investigated.

If the detector finds smoke in the incoming air, it alerts the control system. The control system
must then decide whether or not to shut down the air inlet.

Designing a Dedicated Smoke Control System

Introduction

About Stairtowers

Most of the systems discussed so far have been non-dedicated systems. Even in a building where
the primary smoke control system is non-dedicated, special zones or functions may exist that
require a “dedicated” system. The most common example of a dedicated system is a dedicated
smoke control system for a stairtower.

A “stairtower” is a stairwell with a ventilation system that is isolated from the main building.
The only connection between the building and the stairtower are fire-rated doors on each floor.
Since the building occupants should use the stairtower to leave during an evacuation, keeping the
stairtower smoke-free is vital.

A stairtower has its own dedicated system that pressurizes the stairtower to keep smoke out.
This dedicated system can take several forms, from a fan mounted in the roof of the stairtower, to
a duct system that delivers air to each level.

You must pressurize a stairtower enough to keep smoke out. However, if the pressure in the
stairtower is too great, then opening the doors leading into the stairtower can be difficult.
(See the figure below.)

The ideal stairtower smoke control system must pressurize the stairway enough to keep the smoke
out, but it must not pressurize it so much that the doors cannot be opened. An example of a
dedicated smoke control system for a stairtower is shown in the figure below.

The table below shows the maximum allowable pressure differential across a door in inches water

mechanism exerts as defined in NFPA 92A. At the pressures shown in the table, the door requires 30

Ensuring Doors

Controlling Pressure
in a Stairtower

Table 1-2 assumes a door height of seven feet and a distance from the doorknob to the knob side
of the door of three inches. If your door does not meet these requirements, or has opening
hardware other than a doorknob, such as panic hardware, then refer to the ASHRAE publication
Design of Smoke Control Systems for Buildings for a formula to calculate the proper opening
force. The door widths in Table 1-2 are only valid for doors that are hinged at one end. For other
types of doors, see the ASHRAE document.

Many door closers vary the amount of force as the door opens. They provide less resistance in the
early stages of opening the door than they do later, when the door is almost fully open. The force
to open the door shown in Table 1-2 represents the force needed to open the door only enough to
let air flow through the opening. Once air is able to flow, the force exerted by the difference in air
pressure on the door lessens. Therefore, when calculating the force required to open the door, you
may need to lower the door closer force.

Stairtower smoke control systems are divided into two categories: “non-compensated” and
“compensated.” These categories are illustrated in the figure below, which shows stairtower
pressurization by top injection. Non-compensated systems simply turn on a fan to pressurize the
stairtower, as shown below in Stairtower A. The fan speed does not change to compensate for
doors opening and closing. The more doors that are open, the more the pressure differential
between the stairtower and the building drops.

Vent

Designing a Dedicated Smoke Control System, Continued

Controlling Pressure
in a Stairtower

The building shown in Figure 1-6, Stairtower A has no vent to the outside. Compensated systems
adjust the airflow to make up for pressure lost through open doors. A compensated system
(Figure 1-6, Stairtower B) can use dampers (or vents) to relieve excess pressure in the stairtower
to ensure that the pressure does not go over the maximum limit.

There are a number of ways compensated stairtower smoke control systems can control
pressurization. In a basic system with a roof-mounted fan blowing air into the stairtower, pressure
can be regulated by varying the speed of the fan, the pitch of the fan blade, the inlet vanes, or the
number of fans operating (assuming there is more than one).

More sophisticated systems use ducts to deliver air to several points in the stairtower. The
dampers can be controlled to maintain the appropriate pressure in their zone. Duct systems can
also use bypass dampers and ducts to control the amount of air flowing from the fan to the outlets.
The bypass dampers are opened when the stairtower is at the proper pressure, so that excess air
flows into the bypass duct, then back to the air inlet not into the duct system.

The figure below shows a stairtower pressurization system that uses multiple pressure injection
dampers mounted in an air pressure duct. In this example, the vents to the building have
barometric dampers. While a roof-mounted fan is shown in the figure, the fan can be located at
any level. A manually-operated damper may be located at the top of the stairtower to aid the fire
department in purging smoke from the building during a fire.

The figure below shows a bypass pressure control system for stairtower pressurization with the
bypass-around supply fan located at ground level. Although a ground-level fan is shown, the fan
can actually be placed at any level. The bypass duct dampers are controlled by one or more static
pressure sensors located between the stairtower and the building. In addition, a manually-operated
damper may be located at the top of the stairtower for smoke purging by the fire department.

Bypass Duct Dampers

Figure 1-8. A Bypass Pressure Control System

There are several ways for a compensated stairtower smoke control system to get rid of excess air
pressure to ensure that the stairtower doors can open properly. One or more vents to the building
exterior (with dampers) can be used in the stairtower to release excess pressure. These dampers
can be barometrically controlled (being forced open by the excess air pressure) or controlled by
electric motors or pneumatics as in conventional HVAC systems. In both cases, the dampers must
be placed far enough away from the air supply to prevent venting of air that has not yet been able
to disperse through the stairtower. Vents can also lead into the building, but you should consider
carefully the impact of venting extra pressure into the building before using this type of vent.

You can also use an exhaust fan to vent the excess pressure from the stairtower. Such a fan should
be designed to operate only when the stairtower is over-pressurized. It should never be on when
the pressure differential between the building and the stairtower is below the lowest limit.

Designing a Dedicated Smoke Control System, Continued

Elevator Smoke
Control

Most elevators do not have smoke protection, fire protection, or other features necessary for them
to be considered as a means for fire evacuation. Elevator systems not specifically designed and
built for fire evacuation should not be used in fire situations.

The elevator smoke control system is intended to prevent smoke flow to other floors by way of the
elevator shaft. Elevator shafts present a special menace with regards to smoke control. An elevator
shaft makes a perfect chimney to draw smoke into the upper levels of a building. Since elevators
usually have openings on each floor, and the seals on the elevator doors are often poor, the
elevator shaft can become a mechanism to spread smoke throughout a building. Smoke control in
an elevator shaft is an important consideration in the overall smoke control plan.
The problems resulting from smoke migration through elevator shafts are illustrated by the
MGM Grand Hotel fire. Although the fire occurred on the ground floor, the smoke from that fire
migrated through the elevator shafts to the upper floors resulting in a number of fatalities.

An obvious solution to this problem is to pressurize the elevator shafts, as shown in the figure
below. However, pressurizing an elevator shaft presents a number of problems. While the elevator
doors can be fitted with improved seals and rubber sweeps, these systems will not totally eliminate
air leakage. Also, most elevator shafts are not designed to be pressurized. They often have large
openings at the top where the cables feed into the winding room. Shafts are often constructed of
porous material that cannot contain the air pressure. And since most shafts are not designed to be
inspected after the elevators are installed, finding and repairing cracks that would let smoke
infiltrate or pressure escape is difficult.

Figure 1-9. Pressurizing an Elevator Shaft to Prevent Smoke Migration

Even if the shaft is pressurized, another primary problem is caused by the transient pressures
produced when an elevator car moves inside the shaft during a smoke emergency. This “piston
effect” can pull smoke into a normally pressurized elevator lobby or elevator shaft. For example,
an elevator car moving down from the top of the shaft may create a small low air pressure zone
near the top of the shaft, which can pull smoke from the fire zone into the shaft.

At the present time, these issues have not been resolved. Pressurizing the elevator shafts so that
the elevators can operate during a smoke emergency is still being studied.

IMPORTANT: In general, elevators should not be used as an escape route during

an evacuation.

1-18

Detecting Smoke

Introduction

Configuring and
Monitoring a Smoke
Control System

The fire detection system is the system that is connected to the smoke or heat detectors. Every
smoke zone should have a Listed smoke or heat detector installed in it. The detectors should be
located so that they can detect the presence of smoke or fire before it spreads beyond the zone.
Once the fire control system detects the fire, it relays to the smoke control system the zone and the
type of alarm that was triggered. The smoke control system then takes action.

Never use manual pull stations to initiate specific zoned smoke control. There is no guarantee that
the person pulling the alarm is in the same smoke zone as the fire. The automatic smoke control
system should take only those actions that are common to all smoke strategies when a manual pull
station is activated. For example, the stairtower can be pressurized in response to a manual pull
box alarm. Implementing a specific smoke control strategy must wait until the smoke detectors
locate the fire zone.

The smoke control system should be able to act on its own in response to detecting smoke.
When it detects smoke, the system enacts the planned strategy of the designer. The automatic
smoke control should maintain the strategy to control smoke in the first zone that smoke is
detected in. It would be difficult for you to create strategies for controlling smoke in all possible
combination of zones.

The automatic smoke control system must have the highest priority over all other automatic
control systems in the building. It must override energy management, occupancy schedules, or
other controls. The only systems that should be able to automatically override the smoke control
system are such safety systems as high pressure limiters.

Considering how unpredictable smoke is, you must have a manual control panel from which the
smoke control system can be monitored and overridden. This panel, called a “Firefighter's Smoke
Control Station” (FSCS), allows fire-fighting personnel to take manual control of the smoke
control system.

Firefighter Smoke
Control Station
(FSCS)

The FSCS is a graphic annunciating control panel that gives firefighters information about the
state of the smoke control system, as well as manual control over all of its components. The FSCS
should be located in a secure room or cabinet to prevent unauthorized personnel from tampering
with it. The room or cabinet should be clearly marked so that firefighters can quickly locate the
FSCS.

The FSCS panel has a diagram of the building showing the entire smoke control system, along
with status lights and override switches for all of the system components. The diagram of the
building should include all smoke control zones, all of the ducts leading to and from the zones
with arrows indicating the direction of air flow in the ducts, and a clear indication of which zone
each piece of equipment serves.

The panel must have controls to activate all fans, dampers, and other equipment related to the
smoke control system. These manual controls must be able to override all automatic control of
smoke control equipment. In particular, the FSCS must be able to override:

• Hand/off/auto switches.

• Local start/stop switches on fan motor controllers.

• Freeze detection devices.

• Duct smoke detectors.

Continued on next page

1-19

Detecting Smoke, Continued

Firefighter Smoke
Control Station
(FSCS)

The FSCS must not override such safety controls as:

• Electrical overload protection.

• Electrical disconnects as required by NFPA 70.

• Other controls in accordance with UL 864.

• Any fire/smoke damper thermal control as required by UL 33, Standard for Heat Responsive Links for

Fire Protection Service or UL 555S, Standard for Leakage Rated Dampers for Use in Smoke Control
Systems.

In non-dedicated systems, local motor controller hand/off/auto switches can remain in-circuit with the FSCS
panel. But, they can remain in-circuit only if the switches are in a locked room accessible only to authorized
personnel. Also, if such a switch is thrown, a trouble condition must sound in the building main control
center. The indicator lights on the FSCS provide information about the functioning of the system.
The following colors for example are used for FSCS indicators:

• Green - Smoke-control fans and other critical-operation devices are running or the dampers are open.

• Yellow - Dampers are in the closed position.

• Orange or Amber - The equipment has failed.

• Red - A fire has been detected in the area.

The FSCS has a lamp test button that turns ON all the panel lights. Use this button regularly to make sure
none of the lights has burned out. The FSCS gets information on the status of the smoke control system
equipment from proof monitors on the equipment itself. Each fan that has a capacity of over 2,000 cfm
should be equipped with an airflow monitor. A proof sensor is required to monitor airflow and the position of
the blade or vane in a damper is also required to be monitored. Smoke dampers should be fitted with end­range switches to indicate that they are fully-opened or fully-closed.

All of the failure lights on the FSCS represent the state of the equipment as determined by the proof sensors.
The failure light comes on if the piece of equipment is not in the state its control is set for within its trouble
indication time. This time is a maximum of 60 seconds for a fan (see note) and a maximum 75 seconds for a
damper. If, within that time, the proof sensors do not report that the piece of equipment has responded to the
control system command, the FSCS indicates that the piece of equipment has failed.

Note: Local codes may require shorter maximum times. The 60 second maximum time for the fan must

also account for ramp down time.

Testing the System

Related
Documentation

During the installation, you should perform “operational tests” that make sure the components and
subsystems of the smoke control system are installed correctly. After the installation is done, you must
perform “acceptance tests,” to prove that the smoke control system is capable of doing what it was designed
to do. The testing procedures are covered in a later chapter of this document.

UUKL per the requirement of UL 864, Control Units and Accessories for Fire Alarm Systems.
Additionally, system equipment must be in accordance with locally adopted codes such as
NFPA 92A and the pertinent building codes.

Some of the smoke control considerations are as follows:

• Standby Power - Standby power for Simplex Smoke Control System Equipment is optional, however if

the equipment also provides fire alarm service then standby power would be required.

• Smoke Control Actuating Input Circuits - The circuits which connect to devices which initiate

automatic smoke control must consist of one of the following:

- A supervised fire alarm initiating circuit of a Fire Alarm Control Unit which is also
providing smoke control.

- A supervised circuit connected to a zone output of a UL Listed Fire Alarm Control Unit.

- An unsupervised circuit connected to a zone output of a Listed Fire Alarm Control Unit
with each unit mounted adjacent (within twenty feet) to the other and the interconnecting
wiring run in conduit.

• Firefighter’s Smoke Control Station - Each system must also provide a Firefighter’s Smoke Control

Station (FSCS) as defined in NFPA 92A. The FSCS provides a complete and easily understood system
status, with provisions for manually overriding any smoke control process.

The contents of this document are derived from Standard NFPA 92A Recommended Practice for
Smoke-Control Systems. Additional construction and reliability concerns, not covered in
NFPA 92A, are derived from similar requirements governing Fire Alarm Control Units as found in
UL Standard 864. Detailed engineering design information is contained in the ASHRAE
publication, Design of Smoke Management Systems.

Weekly Self-Test

Verifying System
Integrity During
Emergency
Conditions

The means for verifying system integrity during a non-emergency condition varies depending on
whether the smoke control system is a “dedicated” or a “non-dedicated” system.

• Dedicated Smoke Control Components: Solely used for smoke control functions and are

not operated in a non-emergency condition. Dedicated system equipment is therefore required
to incorporate an automatic weekly self-test of each smoke control function.

• Non-dedicated Smoke Control Components: HVAC components within a building which

are operated regularly. The normal “comfort” level associated with the proper operation of the
equipment serves as the means of maintaining system integrity.

The weekly self-test consists of the smoke control system automatically commanding the
associated function to operate and expecting, within a specified time, that the associated proof
sensor will operate. A valid proof sensor operation does not have to be annunciated. However, the
lack of an expected proof sensor operation should produce an audible trouble signal and indicate
the specific device which did not operate.

Smoke control system equipment must verify that a fan or damper has achieved its required end
function during emergency conditions. This end-process verification consists of monitoring fans
by vane or pressure differential switches, and dampers by degree-of-opening switches. These
monitored switches are further connected back to an input monitoring circuit of the Smoke
Control System Equipment, programmed to expect a signal within a specified time after an
automatic or manual activation. Annunciation of the end-process verifies that the process operates
as intended; if the proof sensors fail to operate, an audible trouble signal is sounded.

Automatic
Activation

Where equipment used for smoke control is also used for normal building operation, control of
this equipment must be preempted or overridden as required for smoke control. Automatic
activation of systems and equipment for zoned smoke control must have the highest priority over
all other sources of automatic control within the building. This equipment includes air
supply/return fans and dampers subject to automatic control according to building occupancy
schedules, energy management, or other purposes. The following controls should not be
automatically overridden:

• Static pressure high limits.

• Duct smoke detectors on supply air systems.

Subsequent
Automatic
Activation

Automatic
Activation By a
Manual Pull Box

Manual Operation

Automatic Override
of Manual Activation

Once an automatic activation has occurred, subsequent alarm signals that would normally result in
the automatic actuation of a smoke control strategy shall be annunciated only. No fans or dampers
should be actuated in response to any subsequent automatic fire alarm signal in order to avoid the
possibility of defeating any smoke control strategies that are in process.

Activation of the smoke control system should be by smoke detectors and any other automatic
devices located within the zone covered by the specific air conditioning and ventilating system.

Manual fire alarm pull boxes should not be used to initiate specific zoned smoke control
strategies because such a pull box in an adjacent smoke zone may be pulled, thereby placing the

system in an incorrect mode.

It is desirable that the smoke control system be independently controlled from a smoke control
center which should have controls capable of overriding all other HVAC systems. A manual
command is capable of overriding either fully or partially any automatic activation that may be in
process. This is based on the assumption that any manual activation is performed by authorized
personnel in response to a known emergency condition.

Since smoke control operation must override any programmed HVAC function, it is considered
acceptable for the “Initial Automatic Activation” to override any manual control, initiated by any
other operator terminal other than the FSCS, which is currently in place.

NFPA Standard 92A requires that manual control initiated by the FSCS take precedence over
automatic control. Therefore, the smoke control system automatic programmed functions do not
override a manual FSCS control when a smoke control operation is initiated.

Example: When a switch at the FSCS is operated, the control point is activated or deactivated

at a priority higher than the automatic smoke control program or any other operator
terminal priority. This prevents the automatic smoke control program or manual
commands from other operator terminals from overriding commands initiated at the
FSCS.

4190 TrueSite

Workstation TSW

The 4190 TrueSite Workstation (TSW) provides a graphical user workstation within the Simplex
Smoke System. You can interact with the smoke control system by entering input through a
keyboard, mouse, or touch-screen.

Note: If a TSW is used in the system, a Firefighter’s Smoke Control Station must be provided

and this station must initiate smoke control commands at the highest priority.

Graphic Screens:

TSW graphic screens can provide easily recognizable site plan and floor plan information. The level
of detail can be customized for the specific facility to easily and accurately direct the operator to the
immediate area of interest.

Icons can be optionally added to identify the exact device of interest and the operator can utilize
TSW Pan and Zoom capabilities to move to a specific screen location for more detail.

When a system status change occurs, the screen displays the type and location of the activity.
The operator then touches the appropriate screen area (or uses the mouse control) to access a more
detailed view of the zone or device.

the Simplex Smoke Control System. FSCS panels are custom designed for each building. See the
“FSCS Ordering Information” section later in this chapter.

Figure 3-4. Firefighter’s Smoke Control Station

Continued on next page

3-7

Firefighter Smoke Control Station, Continued

Firefighter Smoke
Control Station
(FSCS)

The smoke control panel must work completely in conjunction with the fire alarm control panel.
This is because the FSCS is used by firefighters to activate and deactivate all smoke control
sequences in the event that the fire spreads and for smoke cleanup operations. All switches
override the automatic operation, in the event of a conflict with the operation. The FSCS must be
able to override any other manual or automatic control that is being used in the system, except
when those controls intended to protect against electrical overloads, provide for personal safety,
or prevent major system damage.

The design of the controls and status indications must be as simple as possible for firefighter use.
Smoke control schemes can sometimes incorporate the simultaneous use of multiple (sometimes
over a hundred) air handling units, exhaust fans, and dampers to accomplish the function.

The FSCS graphic must show all fans in excess of 2000 CFM, all dampers or groups of Variable
Air Volume (VAV) boxes, and all major ducts. The FSCS graphic must depict the direction of
airflow in the ducts. The air handling units, fans, and dampers must be grouped into “systems” or
“smoke zones.” These “smoke zones” are determined by the physical layout of the building and
the smoke and fire barriers as structurally and architecturally designed, for firefighting purposes.

It may be advantageous to provide one switch for each “system” or “smoke zone.” With the
appropriate units interlocked to manage smoke in the affected area, there could be potentially
hundreds of H-O-A switches. Fans require a three-position control that provides ON-AUTO-OFF
capabilities. Dampers require a three-position control that provides OPEN-AUTO-CLOSE
capabilities. The AUTO position can be removed if the piece of equipment can only be controlled
by the FSCS.

Smoke Management zones can be provided with a three-position switch, in addition to the
required switches, that provides PRESSURIZE-AUTO-EXHAUST capabilities. Status indications
are required for each system to positively indicate that a smoke control sequence has been
initiated. Fans must have a single green indicator that turns on when the fan proof sensor indicates
that the fan is running.

Dampers have three indicators:

• Yellow: Turns ON when the damper proof sensor confirms that the damper is closed

• Green: Turns ON when the damper proof sensor confirms that the damper is open

• Amber: Turns ON to indicate failure.

These indicators must be OFF when the damper is between the open and closed position.

The FSCS must have a Red indicator for each smoke control zone to signal if the zone is currently
in an alarm condition.

The FSCS must have Amber/Orange indicators to annunciate equipment faults from each piece of
equipment monitored by proof sensors. If fans do not indicate running within 60 seconds, or
dampers do not reach the required position within 75 seconds, a fault indication must be
annunciated on the FSCS.

Note: Confirm actual times with local codes.

The FSCS must have a “master key-switch” to prevent unauthorized personnel from issuing
commands. When the key is inserted and turned, all controls on the FSCS are enabled. Alternate
command control may be performed by being inside a locked enclosure or other access control
means that are accepted by local authority.

Firefighter Smoke Control Station, Continued

Firefighter Smoke
Control Station
(FSCS)

FSCS Ordering
Information

The FSCS must have an audible signal that sounds when either a smoke control zone is in alarm or
to bring attention to a fault indicator. Operating the key-switch and then pressing the audible
silence button is the only method of silencing the FSCS audible signal.

The FSCS must have an “Audible Silence Button.” This momentary push-button is activated only
when the master key-switch is ON. This button is used to silence the FSCS audible signal that
activated as a result of proof sensors failing to report or annunciation of smoke detection within
the FSCS smoke control zones.

The FSCS must have a means to turn OFF equipment fault indicators that were activated as a
result of proof sensors failing to report within the required time period. If a “Clear Faults Button”
or similar means to clear faults, is used it would be active only when the master key-switch is ON.
An alternate means may be by logging in at an authorized level at the Fire Alarm Control Panel
and then clearing the faults.

The FSCS must have a “Lamp Test Button.” This momentary push-button is active at all times to
turn ON all indicators to allow for visual confirmation of failed indicator LEDs.

Note: Refer to Chapter 4 for a list of Simplex Field Wiring Diagrams and Interconnection

Diagrams that can assist you in installing the Simplex Smoke Control System.

A Firefighter’s Smoke Control Station (FSCS) consists of a site-specific, customized floor plan or
elevation graphic, illuminated status indicators, and switches. The FSCS uses Simplex LED
drivers and switch input modules (Models 4100-7401 through -7404 and 4602-7101) that
communicate with the 4100U/4100ES FACP by means of a supervised RUI communications
channel. The Models 4100-7401 through -7404 and 4602-7101 have been found suitable for use as
components internal to a UL-Listed FSCS manufactured by others.

There are several suppliers of UL-listed FSCS. Below are references to two manufacturers known
to have UL Listed FSCS equipment utilizing Simplex LED drivers and switch modules when this
document was published. Since manufacturer's Listing compliance may change, always verify
smoke control system equipment listing compliance of the FSCS before placing your FSCS order.:

About the Fire Alarm
Control Panel

The Fire Alarm Control Panel connects to all of the smoke detectors, manual pull boxes, fire
alarms, etc. within the building. When one of the FACP sensors detects a problem, the FACP
informs the smoke control panel which sensor is in alarm condition and what the alarm condition
is. The smoke control system receives all alarm information from the FACP. However, the smoke
control zones must correspond to the zones of the FACP.

Introduction

In this Chapter

This chapter contains general guidelines for smoke control installations and interconnections.
Please refer to the applicable installation documents for component installation instructions. These
documents are shipped with the individual components.

All wiring in the Simplex Smoke Control System must comply with the National Electric Code
(NFPA 70), the National Fire Alarm Code (NFPA 72), the appropriate Simplex Field Wiring
diagrams (refer to the “Field Wiring and Interconnection Diagrams” section of this chapter) and
any state or local requirements.

General Smoke Control Interconnections

Overview

A Simplex Smoke Control System is usually part of a larger Simplex Fire Alarm System. The
Simplex Smoke Control System ties into the building air handling equipment, either dedicated,
non-dedicated, or both, to form the overall Smoke Management system for the building.

Since Simplex equipment is not the primary control equipment for a building's non-dedicated air
handling equipment, the interconnection between the Simplex Smoke Control System and the
non-dedicated air handling equipment is critical. This interconnection must be done in such a
manner to guarantee that the Smoke Control System takes priority, and that Smoke Control
System commands cannot be overridden by other building systems.

Although every application is different, the sections that follow describe some typical methods for
interconnecting to air handling elements to insure that Smoke Control System commands take
precedence and that accurate monitoring of the air handling system is fed back into the Smoke
Control System. Fan and damper control are shown in some detail to illustrate principles that can
be extrapolated to other more special purpose applications. These principles should be generally
applied to the detailed design of specific engineered smoke control solutions.

Smoke Control System operation is dependent both on the hardware and the control software.
The wiring diagrams shown in this chapter, must be used with appropriate programming to create
an operational control system.

Dedicated Smoke Control System Wiring

Overview

Dedicated
Damper Control

Dedicated Smoke Control System wiring is usually straightforward. The Smoke Control System is
the only source for commands to the fans and dampers, and therefore bypass and cut-off relays are
not needed. The following sections illustrate some examples of dedicated fan and damper control.

Damper control is a basic function of the Simplex Smoke Control System. Interconnections to
motorized dampers are shown in Figures 4-2 and 4-3.

The figure below shows dedicated motorized damper control using a 4090-9120 6-Point I/O
Module. Both relay outputs are used, one to control opening the damper and the other to control

The wiring between the 6-Point I/O Module and the control relays is unsupervised, so the module
must be mounted within three feet of the relays/dampers in accordance with NFPA 72.

Note: The wiring to the limit switches is supervised and limited to 500 ft. (152 m).

Like smoke dampers, fan control is a basic function of the Simplex Smoke Control System.
General principles for interconnection to a dedicated fan are shown in Figures 4-4 and 4-5.

In a dedicated fan control application, the 4090-9118 Relay IAM is used to provide inputs to a fan
to turn it ON and monitor the feedback from the controller. The wiring between the Relay IAM
and the fan is unsupervised, so the IAMs must be mounted within three feet of the controller in

Non-Dedicated Smoke Control System Wiring Diagrams

Overview

Non-Dedicated
Damper Control

Non-dedicated Smoke Control System wiring adds a layer of complexity, as the Smoke Control
System must take control of the fans and dampers from the HVAC system. This introduces the use
of bypass and cutoff relays not needed in a Dedicated Smoke Control System. The following
sections illustrate some examples of non-dedicated damper and fan control.

Damper control and overriding the HVAC control of the damper is a basic function of the Simplex
Smoke Control System. Interconnections for dampers are shown in Figures 4-6 through 4-9.

Control of the damper is accomplished using the 4090-9118 Relay IAM. The Relay IAM
communicates with the FACP via the Simplex IDNet Signaling Line Circuit (SLC). When
commanded by the FACP the Relay IAM activates the smoke control override relay and supplies
power to the pressure switch to close the damper.

Non-Dedicated
Damper Control

Feedback of the closure is accomplished using a 4090-9120 6-Point I/O Module to monitor the
closed position limit switch on the damper. The module also communicates with the Simplex
FACP via IDNet. Wiring from the module to the control relay is unsupervised, so it must be
mounted within three feet of the relay/damper in accordance with NFPA 72.

Figure 4-6. Non-Dedicated Motorized Damper Control

The two relay circuits of the 6-Point I/O Module are used, one to control opening the damper and
the other to control closing it. Relays [A] and [B] are activated to close the damper. One output
circuit controls Relay [A] to override the Energy Management System (EMS) and provide power
to the motor to close the damper. Relay [B] insures that no open power is provided to the motor
from the EMS. The other output circuit works in exactly the opposite fashion to control the
opening of the damper. The damper position is monitored by the two supervised inputs of the
6-Point I/O Module.

The wiring between the 6-Point I/O Module output circuits and the relays is unsupervised, so the
6-Point I/O Module must be mounted within three feet of the relays/dampers in accordance with
NFPA 72. The wiring to the limit switches is supervised, so no such restriction exists with the
monitor circuits.

Smoke Control System Programs

Introduction

In this Chapter

This chapter provides examples of Simplex Smoke Control System programs. These programs are
presented to illustrate what can be accomplished with this system. Since every system is unique,
your programs will not be identical to these programs. Instead, use these programs as templates
when programming the system.

Keep in mind the following smoke control objectives when programming the system:

• Maintain safe fire-free and smoke-free routes to allow sufficient time for the occupants to exit

the premises or move to designated safe refuge areas.

• Provide a relatively clear approach to the fire area by firefighters so that the fire (the source of

the smoke) can be contained and extinguished as fast as possible.

• If designated safe refuge areas are a part of the life safety design, then the control system must

prevent smoke migration into such areas for a prolonged period of time.

• Reduce the amount of fire and smoke damage to the property.

Refer to the page number listed in this table for information on a specific topic.

Smoke Control Program Requirements

Introduction

Emergency
Operation

Automatic Program

Dedicated Smoke
Control System
Weekly Self-Test

The following paragraphs describe the requirements for the various types of programs that can be
implemented using the Simplex Smoke Control System.

Emergency operation programs have the following functions:

• Zoned smoke control to activate from automatic devices only.

• Manual devices may cause any operation that is common to all smoke strategies

(e.g. Stairtower Pressurization).

•

Automatic operation programs have the following functions:

• The first alarm in sets the operation strategy for smoke control. Subsequent alarms do not change the

smoke control strategy operation. The first alarm in sets that zone ON, and the other zones OFF. (See
Equations 9, 11, 13, and 15.)

• The program checks proof sensors and reports equipment operation to the FSCS or, if such proof is not

received within a specified time from activation it reports any failure to the FSCS. The delay time to
allow sensors to operate is set at ten seconds for conversion in testing. This delay time can be increased
to accommodate the time it takes for the equipment to respond. The maximum delay time is 60 seconds
for fans (Equations 19 through 24) and 75 seconds for dampers (Equations 25 through 46).

• Manual operation of the FSCS control switches overrides the automatic program. Manual commands

have a higher priority than automatic operations. (See Equations 47 through 74.)

Dedicated smoke control system weekly self-test programs have the following functions:

• Begins Saturday at 0000 hours if there is no alarm.

• Run once. Any failures sound an audible fault signal and light an indicator on the FSCS showing the

device that failed. In addition, the program displays “Weekly Smoke Control Self-Test Failed (Time &
Date).”

Glossary of Terms

Glossary

Acceptance Tests – Tests designed to prove a smoke control system is capable of doing what is
designed to do.

AHJ – The “Authority Having Jurisdiction” is the organization, office, or individual responsible
for approving equipment, an installation, or a procedure.

Alarm Service – The service required following the receipt of an alarm signal.

Alarm Signal – A signal indicating an emergency requiring immediate action, as an alarm for fire

from a manual box, a waterflow alarm, an alarm from an automatic fire alarm system, or other
emergency signal.

Alarm System – A combination of compatible initiating devices, control panels, and notification
appliances designed and installed to produce an alarm signal in the event of fire.

Annunciator – A unit containing two or more identified targets or indicator lamps in which each
target or lamp indicates the circuit, condition, or location to be annunciated.

Auxiliarized Local System – A local system that is connected to the municipal alarm facilities.

Auxiliarized Proprietary System – A proprietary system that is connected to the municipal alarm

facilities.

Auxiliary Protective Signaling System – A connection to the municipal fire alarm system to
transmit an alarm of fire to the municipal communications center. Fire alarms from an auxiliary
alarm system are received at the municipal communications center on the same equipment and by
the same alerting methods as alarms transmitted from municipal fire alarm boxes located on
streets.

Auxiliary Trip Relay – A relay used to operate a municipal master box from an auxiliarized
control panel.

Bell, Single Stroke – A bell whose gong is struck only once each time operating energy is applied.

Bell, Vibrating – A bell that rings continuously as long as operating power is applied.

Box (or Station), Fire Alarm – (1) Non-coded. A manually operated device that, when operated,

closes or opens one or more sets of contacts and generally locks the contacts in the operated
position until the box is reset. (2) Coded. A manually operated device in which the act of pulling a
lever causes the transmission of not less than three rounds of coded alarm signals. Similar to the
non-coded type, except that instead of a manually operated switch, a mechanism to rotate a code
wheel is utilized. Rotation of the code wheel, in turn, causes an electrical circuit to be alternately
opened and closed, or closed and opened, thus surrounding a coded alarm that identifies the
location of the box. The code wheel is cut for the individual code to be transmitted by the device
and can operate by clockwork or by an electric motor. Clockwork transmitters can be pre-wound
or can be wound by the pulling of the alarm lever. Usually the box is designed to repeat its code
four times and automatically come to rest. Pre-wound transmitters must sound a trouble signal
when they required rewinding. Solid state electronic coding devices are also used in conjunction
with the fire alarm control unit to produce coded sounding of the audible signaling appliances.

Break-glass Box (or Station) – A break-glass box is one in which it is necessary to break a
special element in order to operate the box.

Bypass Pressure Control System – The bypass-around supply fan can actually be placed at any
level. The bypass duct dampers are controlled by one or more static pressure sensors located
between the stairtower and the building. In addition, a manually operated damper may be located
at the top of the stairtower for smoke purging by the Fire Department.

CC – Custom Control.

Central Station System – A system, or group of systems, in which the operations of circuits and

devices are signaled automatically to, recorded in, maintained, and supervised from an approved
central station having competent and experienced observers and operators who, upon receipt of a
signal, take the required action. Such systems are controlled and operated by a person, firm, or
corporation whose principal business is the furnishing and maintaining of supervised signaling
service.

Channel – A path for signal transmission between two or more stations or channel terminations.
A channel can consist wire, radio waves, or equivalent means of signal transmission.

Chimes – A single stroke or vibrating-type audible signal appliance that has a xylophone-type
striking bar.

Circuit Interface – A functional assembly that interfaces one or more of its initiating device
circuits with a signaling line circuit in a manner that permits the central supervising station to
indicate the status of each of its individual initiating device circuits.

Circuit – The conductors or radio channel, and associated equipment used to perform a definite
function in connection with an alarm system.

Coded Signal – A signal pulsed in a prescribed code for each round of transmission. A minimum
of three rounds and a minimum of three impulses are required for an alarm signal.

Combination Detector – A device that either (1) responds to more than one of the fire
phenomena such as smoke, heat, flame, and fire gas or (2) employs more than one operating
principle to sense one of these phenomena. Typical examples are (1) a combination of heat
detector with a smoke detector, or (2) a combination rate-of-rise and fixed temperature heat
detector.

Combination System – A local protective signaling system for fire alarm, supervisory, or guard
tour supervisory service whose components may be used in whole or in part in common with a
non-fire signaling system such as a paging system, a burglar alarm system, a musical program
system, or a process monitoring service system, without degradation of or hazard to the protective
signaling system.

Communication Channel – A signaling channel (usually leased from a communication utility
company) having two or more terminal locations and a suitable information handling capacity
depending on the characteristics of the system used. One terminal location is at the central
supervising station and the other terminal location or locations are sources from which are
transmitted alarm signals, supervisory signals, trouble signals, and such other signals as the central
supervising station is prepared to receive and interpret.

Compensated System – Adjust the airflow to make up for pressure lost through open doors.
A compensated system can use dampers (or vents) to relieve excess pressure in the stairtower to
ensure that the pressure does not go over the maximum limit.

Control Unit – A device with the control circuits necessary to (a) furnish power to a fire alarm
system; (b) receive signals from alarm initiating devices and transmit them to audible alarm
notification appliances and accessory equipment; and (c) electrically supervise the system
installation wiring and primary (main) power. The control unit can be contained in one or more
cabinets in adjacent or remote locations.

Dedicated Smoke Control Components – Solely used for smoke control functions and are not
operated in a non-emergency condition. Dedicated system equipment is therefore required to
incorporate an automatic weekly self-test or each smoke control function.

Dedicated Smoke Control System – Installed in a building for the sole purpose of controlling
smoke.

Delinquency Signals – A signal indicating the need of action in connection with the supervision
of guards or system attendants.

Duct System – Use bypass dampers and ducts to control the amount of air flowing from the fan to
the outlets. The bypass dampers are opened when the stairtower is at the proper pressure, so that
excess air flows not into the duct system, but into the bypass duct and back to the air inlet.

Emergency Voice/Alarm Communication Systems – A system that provides dedicated manual
or automatic, or both, facilities for originating and distributing voice instructions, as well as alert
and evacuating signals pertaining to a fire emergency to the occupants of a building.

EOL Device – End of Line Device. A device used to terminate a supervised circuit.
