Chapter 1

Smoke control overview

Smoke is one of the major problems created by a fire. Smoke threatens life and property, both in the immediate location of the fire and in locations remote from the fire. The objectives of smoke control include:

• Maintain reduced-risk escape route environments

• Diminish smoke migration to other building spaces

• Reduce property loss

• Provide conditions that assist the fire service

• Aid in post-fire smoke removal

Smoke consists of airborne solid and liquid particulates, gases formed during combustion, and the air supporting the particulates and gases. Smoke control manages smoke movement to reduce the threat to life and property. This chapter describes:

• Methods of smoke control

• Applications of smoke control methods

• Smoke detection and system activation

• Design approaches to smoke control

• Design considerations for smoke control

BAS-APG001-EN 1

Chapter 1 Smoke control overview

Methods of smoke control

Smoke control system designers use five methods to manage smoke. They use the methods individually or in combination. The specific methods used determine the standards of design analysis, performance criteria, acceptance tests, and routine tests. The methods of smoke control consist of: compartmentation, dilution, pressurization, air flow, and buoyancy.

Compartmentation method

The compartmentation method provides passive smoke protection to spaces remote from a fire. The method employs walls, partitions, floors, doors, smoke barriers, smoke dampers, and other fixed and mechanical barriers. Smoke control system designers often use the compartmentation method in combination with the pressurization method.

Dilution method

The dilution method clears smoke from spaces remote from a fire. The method supplies outside air through the HVAC system to dilute smoke. Using this method helps to maintain acceptable gas and particulate concentrations in compartments subject to smoke infiltration from adjacent compartments. In addition, the fire service can employ the dilution method to remove smoke after extinguishing a fire. Smoke dilution is also called smoke purging, smoke removal, or smoke extraction.

Within a fire compartment, however, dilution may not result in any significant improvement in air quality. HVAC systems promote a considerable degree of air mixing within the spaces they serve and building fires can produce very large quantities of smoke. Also, dilution within a fire compartment supplies increased oxygen to a fire.

Pressurization method

The pressurization method protects refuge spaces and exit routes. The method employs a pressure difference across a barrier to control smoke movement ( either the refuge area or an exit route. The low-pressure side is exposed to smoke. Airflow from the high-pressure side to the low-pressure side (through construction cracks and gaps around doors) prevents smoke infiltration. A path that channels smoke from the low-pressure side to the outside ensures that gas expansion pressures do not become a problem. A top-vented elevator shaft or a fan-powered exhaust can provide the path.

(In.w.c. [Pa])

• The minimum pressure difference column provides the pressure

difference between the high pressure side and the low-pressure side.

• The minimum pressure difference values incorporate the pressure

induced by the buoyancy of hot smoke.

• A smoke control system should maintain the minimum pressure

differences regardless of stack effect and wind.

• The minimum pressure difference values are based on

recommendations in NFPA 92A (NFPA 2000, Recommended Practice for Smoke Control Systems).

• In.w.c. is inches of water column.

• Pa is Pascals.

Airflow method

The airflow method controls smoke in spaces that have barriers with one or more large openings. It is used to manage smoke in subway, railroad, and highway tunnels. The method employs air velocity across or between barriers to control smoke movement (

Figure 2).

Figure 2: Sample airflow method

4 BAS-APG001-EN

Applications of smoke control methods

A disadvantage of the airflow method is that it supplies increased oxygen to a fire. Within buildings, the airflow method must be used with great caution. The airflow required to control a wastebasket fire has sufficient oxygen to support a fire 70 times larger than the wastebasket fire. The airflow method is best applied after fire suppression or in buildings with restricted fuel. For more information on airflow, oxygen, and combustion, refer to Huggett, C. 1980, Estimation of Rate of Heat Release by Means of Oxygen Consumption Measurements, Fire and Materials.

Buoyancy method

The buoyancy method clears smoke from large volume spaces with high ceilings. The method employs paths to the outside and relies on hot combustion gases rising to the highest level in a space. At the high point, either a powered smoke exhausting system or a non-powered smoke venting system clears the smoke.

Applications of smoke control methods

Applying the methods of smoke control to spaces within a building provides a building smoke control system. Smoke control methods are most commonly applied to building spaces to provide zoned, stairwell, elevator shaft, and atrium smoke control.

Note:

It is beyond the scope of this user guide to provide mathematical design analysis information for smoke control. For references to design analysis information, see References.

Appendix A,

Zoned smoke control

Zoned smoke control uses compartmentation and pressurization to limit smoke movement within a building. Typically, a building consists of a number of smoke control zones. Barriers (partitions, doors, ceilings, and floors) separate the zones. Each floor of a building is usually a separate zone (

Figure 3 on page 6). However, a zone can consist of more than one

floor, or a floor can consist of more than one zone.

The zone in which the smoke is detected is the smoke control zone. Zones next to the smoke control zone are adjacent zones. Zones not next to the smoke control zone are unaffected zones.

Pressure differences produced by fans limit smoke movement to adjacent and unaffected zones. The system may pressurize adjacent zones and leave all unaffected zones in normal operation (Figure 3(a) and Figure 3(c),

page 6). Pressurizing adjacent zones creates a pressure sandwich. Or, the system may pressurize adjacent zones and some unaffected zones (Figure 3(b), control zone, putting it at a negative pressure, relative to adjacent zones.

page 6). In either case, the system exhausts the smoke

BAS-APG001-EN 5

Chapter 1 Smoke control overview

Zoned smoke control cannot limit the spread of smoke within the smoke control zone. Consequently, occupants of the smoke control zone must evacuate as soon as possible after fire detection.

Figure 3: Sample arrangements of smoke control zones

+ : Represents high-pressure zone – : Represents low-pressure zone

When an HVAC system serves multiple floors (Figure 4 on page 7) and each floor is a separate zone, the following sequence provides smoke control:

1. In the smoke control zone, the smoke damper in the supply duct closes and the smoke damper in the return duct opens.

2. In adjacent and/or unaffected zones, the smoke dampers in the return ducts close and smoke dampers in the supply ducts open.

3. If the system has a return air damper, it closes.

4. Supply and return fans activate.

6 BAS-APG001-EN

Applications of smoke control methods

Figure 4: Sample HVAC operation during smoke control

Note:

For simplicity, Figure 4 does not show the ducts on each floor or the penthouse equipment.

When an HVAC system serves only one smoke control zone, the following sequence provides smoke control:

1. In the smoke control zone, the return/exhaust fan activates, the supply fan deactivates.

2. The return air damper closes, and the exhaust damper opens (optionally, the outside air damper closes).

3. In the no-smoke zone, the return/exhaust fan deactivates, the supply fan activates.

4. The return air damper closes, and the outside air damper opens (optionally, the exhaust air damper closes).

Stairwell smoke control

Stairwell smoke control uses pressurization to prevent smoke migration through stairwells to floors remote from the source of the smoke. Secondarily, it provides a staging area for fire fighters.

In the smoke control zone, a pressurized stairwell maintains a positive pressure difference across closed stairwell doors to limit smoke infiltration to the stairwell. Stairwell smoke control employs one or more of these design techniques: compensated pressurization, noncompensated pressurization, single injection pressurization, and multiple injection pressurization.

Compensated pressurization technique

The compensated stairwell pressurization technique adjusts air pressure to compensate for various combinations of open and closed stairwell access doors. The technique maintains constant positive pressure differences across openings. To compensate for pressure changes, it either employs modulated supply airflow or over-pressure relief.

BAS-APG001-EN 7

Chapter 1 Smoke control overview

If the technique employs modulated supply airflow, a fan provides at least minimum pressure when all stairwell access doors are open. Either a single-speed fan with modulating bypass dampers or a variable frequency drive varies the flow of air into the stairwell to compensate for pressure changes.

If the technique employs over-pressure relief, a damper or fan relieves air to the outside to maintain constant pressure in the stairwell. The amount of air relieved depends on the air pressure in the stairwell. A barometric damper, a motor-operated damper, or an exhaust fan can be used to maintain the air pressure.

Non-compensated pressurization technique

The non-compensated pressurization technique provides a constant volume of pressurization air. The level of pressurization depends on the state of the stairwell access doors. When access doors open, the pressure in the stairwell lowers. When access doors close, the pressure raises. One or more single-speed fans provide pressurization air (

Non-compensated stairwell pressurization works best when:

Figure 5).

• Stairwells are in a lightly populated building (for example: telephone

exchanges and luxury apartments).

• Stairwell access doors are usually closed, but when used, remain open

only a few seconds.

Figure 5: Sample non-compensated system

8 BAS-APG001-EN

Applications of smoke control methods

Single and multiple injection pressurization techniques

The single injection and multiple injection techniques provide pressurization air to a stairwell ( more pressurization fans located at ground level, roof level, or any location in between.

The single injection technique supplies pressurization air to the stairwell from one location.

Figure 6). Both techniques use one or

IMPORTANT

The single injection technique can fail when stairwell access doors are open near the air supply injection point. Pressurization air will escape and the fan will fail to maintain a positive pressure difference across access doors farther from the injection point.

The multiple injection technique supplies pressurization air to the stairwell from more than one location. When access doors are open near one injection point, pressurization air escapes. However, other injection points maintain positive pressure differences across the remaining access doors.

Figure 6: Sample single and multiple injection methods

Elevator shaft smoke control

Elevator shaft smoke control uses pressurization to prevent smoke migration through elevator shafts to floors remote from the source of the smoke. Elevator shaft smoke control is similar to stairwell smoke control. The stairwell pressurization techniques described previously are applicable to elevator shaft pressurization.

BAS-APG001-EN 9

Designating an elevator as a fire exit route is an acceptable, though not typical, practice. NFPA 101 (NFPA 2003, Life Safety Code) allows elevators to be second fire exit routes from air traffic control towers. For

Chapter 1 Smoke control overview

more information about elevator shaft smoke control, refer to Klote, J.K., and Milke, J.A. (Design of Smoke Management Systems, 1992).

Atrium smoke control

Atrium smoke control uses buoyancy to manage smoke in large-volume spaces with high ceilings. The buoyancy of hot smoke causes a plume of smoke to rise and form a smoke layer under the atrium ceiling. NFPA 92B (NFPA 2000, Guide for Smoke Management Systems in Malls, Atria, and Large Areas) addresses smoke control for atria, malls, and large areas. Atrium smoke control techniques consist of smoke exhausting, natural smoke venting, and smoke filling.

Smoke exhausting technique

The smoke exhausting technique employs fans to exhaust smoke from the smoke layer under the ceiling. Exhausting prevents the smoke layer from descending and coming into contact with the occupants of the atrium (

Figure 7). Effective smoke removal requires providing makeup air to the space. Makeup air replaces the air that is exhausted by the fans. If makeup air is not introduced, the space will develop a negative pressure, which will restrict smoke movement.

Figure 7: Sample atrium smoke exhausting technique

10 BAS-APG001-EN

Applications of smoke control methods

Natural smoke venting technique

The natural smoke venting technique employs vents in the atrium ceiling or high on the atrium walls to let smoke flow out without the aid of fans (

Figure 8). The applicability of natural venting depends primarily on the size of the atrium, the outside temperature, and the wind conditions. When smoke is detected, all vents open simultaneously. The flow rate through a natural vent depends on the size of the vent, the depth of the smoke layer, and the temperature of the smoke.

Note:

Thermally activated vents are not appropriate for natural venting because of the time delay for opening.

Figure 8: Sample natural smoke venting technique

BAS-APG001-EN 11

Smoke filling technique

The smoke filling technique allows smoke to collect at the ceiling. Without fans to exhaust the smoke, the smoke layer grows thicker and descends. Atrium smoke filling is viable when an atrium is of such size that the time needed for the descending smoke to reach the occupants is greater than the time needed for evacuation.

People movement calculations determine evacuation time. For information on people-movement calculations, refer to SFPE 1995, Fire Protection Engineering Handbook.

Chapter 1 Smoke control overview

Underground building smoke control

The smoke control objective for underground buildings is to contain and remove smoke from the alarm zone. The smoke control system fully exhausts the alarm zone and provides makeup air to replace the exhausted air.

Setup and zoning of the smoke detectors is part of the fire alarm system engineering effort. The fire alarm system signals the smoke control system to start automatic smoke control operations.

In NFPA 101 (NFPA 2003, Life Safety Code), chapter 11.7 states that an underground building with over 100 occupants must have an automatic smoke venting system. Chapter 14.3, for new educational occupancies, provides smoke zoning requirements. Chapter 12.4.3.3 states that automatic smoke control must be initiated when two smoke detectors in a smoke zone activate. Chapter 12.4.3.3 states that the system must be capable of at least 6 air changes per hour.

Smoke detection and system activation

The appropriate smoke detection and system activation approach depends on the specifics of the smoke control system and on the code requirements. Automatic activation has the advantage over manual activation. Automatic activation provides fast and accurate response. Each smoke control application has detection and activation requirements:

• Zoned smoke control

• Stairwell smoke control

• Elevator smoke control

• Atrium smoke exhaust

12 BAS-APG001-EN

Note:

Smoke detectors located in HVAC ducts should not be the primary means of smoke control activation. Duct detectors have long response times and exhibit degraded reliability when clogged by airborne particles. However, a duct detector signal may be used in addition to a primary means of activation. For more information, refer to Tamura, G.T., Smoke Movement & Control in High-Rise Buildings.

Smoke detection and system activation

Zoned smoke control detection and activation

Zoned smoke control activation occurs on a signal from either a sprinkler water flow switch or a heat detector. For maximum benefit, the zoned smoke control system should only respond to the first alarm. Two design techniques that prevent detection of smoke in zones other than the first zone reporting are:

• Not activating smoke control on smoke detector signals

• Activating smoke control on signals from two separate smoke

detectors located in the same zone

Note:

Zoned smoke control should not activate on a signal from a manual pull station (pull box). If pull box activation does not occur in the zone that contains the fire, activation incorrectly identifies the smoke zone.

Stairwell smoke control detection and activation

Stairwell smoke control activation occurs on an alarm signal from any device, including sprinkler water flow switches, heat detectors, smoke detectors, and manual pull stations (pull boxes). Most stairwell smoke control systems operate in the same manner regardless of the source of the alarm signal.

Elevator smoke control detection and activation

Elevator smoke control activation occurs on an alarm signal from any device, including sprinkler water flow switches, heat detectors, smoke detectors, and manual pull stations (pull boxes). Most elevator smoke control systems operate in the same manner regardless of the source of the alarm signal.

Note:

The description of elevator smoke control detection and activation does not apply to pressurization systems for elevators intended for occupant evacuation.

Atrium smoke exhausting detection and activation

Atrium smoke exhausting activation occurs on a signal from a beam smoke detector. A beam smoke detector consists of a light beam transmitter and a light beam sensor. Typically, the transmitter and the sensor are located apart from each other. However, when located together, the transmitter sends its beam to the opposite side of the atrium. At the opposite side, the beam reflects back to the sensor.

Note:

Atrium smoke control should not activate on a signal from a manual pull station (pull box). Atrium smoke exhaust systems have different operating modes depending on fire location.

BAS-APG001-EN 13

Chapter 1 Smoke control overview

Note:

Atrium smoke control should not activate on signals from sprinkler water flow switches or heat detectors. Since the temperature of a smoke plume decreases with height, activation by these devices may not provide reliable results.

Beam smoke detectors minimize interference problems created by stratified hot air under atrium ceilings. On hot days or days with a high solar load on the atrium roof, a hot layer of air may form under the ceiling. The layer can exceed 120 fire may not be hot enough to penetrate the layer and reach ceilingmounted smoke detectors (

Beam-detector installation typically conforms to one of two configurations: vertical grid or horizontal grid.

Figure 9: Sample stratification

° F (50° C). The smoke from an atrium

Figure 9).

Vertical grid

The vertical grid is the most common beam detector configuration. A number of beam detectors, located at different levels under the ceiling, detect the formation and thickening of a smoke layer. The bottom of the grid is at the lowest expected smoke stratification level.

Horizontal grid

The horizontal grid is an alternate beam detector configuration A number of beam detectors, located at different levels under the ceiling, detect the rising smoke plume. Beam detectors are located:

• Below the lowest expected smoke stratification level

• Close enough to each other to ensure intersection with the plume

14 BAS-APG001-EN

Design approaches to smoke control

Smoke control methods provide a mechanical means of directing smoke movement in an enclosed space. The application of one or more methods to a building provides a building smoke control system. Design approaches to smoke control include the no smoke, tenability, and dedicated system approaches.

No-smoke approach

The no-smoke approach provides a smoke control system that prevents smoke from coming into contact with people or property. Almost all smoke control systems are based on the no-smoke approach.

While the objective is to eliminate all smoke, some smoke occurs in protected spaces. By molecular diffusion, minute quantities of smoke travel against pressurization and airflow. These very low concentrations of airborne combustion products are detected by their odor. These and higher levels of diffused contaminants may not result in high-risk conditions.

Tenability approach

The tenability approach provides a smoke control system that allows smoke to come into contact with occupants. However, in this approach, the smoke control system dilutes the by-products of combustion before they come into contact with people. In atria applications, the natural mixing of air into a smoke plume can result in significant dilution. Tenability criteria vary with the application but may include:

• Exposure to toxic gases

• Exposure to heat

• Visibility

Dedicated system approach

The dedicated system approach, such as stairwell and elevator smoke control, provides a system that has the sole purpose of managing smoke. It does not function during normal building comfort control.

The advantages of the dedicated system approach include:

• The interface is simple, since there are few components to bypass.

• Modification of controls after installation is unlikely.

• Easy operation and control.

• Limited reliance on other building systems.

The disadvantages of the dedicated system approach include:

• Component failures may go undiscovered since they do not affect

normal building comfort control.

• Building systems may require more physical space.

BAS-APG001-EN 15

Chapter 1 Smoke control overview

Design considerations for smoke control

Two occurrences will hinder smoke control:

• Plugholing

• Smoke feedback

Smoke control systems should be designed to address the problems that are caused by plugholing and smoke feedback.

Plugholing

Plugholing occurs when an exhaust fan pulls fresh air into the smoke exhaust ( increases the smoke layer depth. It has the potential of exposing occupants to smoke.

The maximum flow of smoke (Q depends on the depth of the smoke layer and the temperature of the smoke. If the required total smoke exhaust is greater than Q additional exhaust vents will eliminate plugholing. The distance between vents must be great enough that the air and smoke flow near one vent does not affect the air and smoke flow near another vent.

Figure 10). Plugholing decreases the smoke exhaust and

) exhausted without plugholing

max

Figure 10: Sample plugholing

16 BAS-APG001-EN

Design considerations for smoke control

Smoke feedback

Smoke feedback occurs when smoke enters a pressurization fan intake and flows into protected spaces. Design techniques reduce the probability of smoke feedback:

• Supply air intakes located below openings from which smoke might

flow, such as building exhausts, smoke shaft outlets and elevator vents.

• Automatic shutdown capability to stop the system in the event of

smoke feedback.

For more information on smoke feedback, refer to SFPE 1995, Fire Protection Engineering Handbook.

Pre-installation considerations

This chapter provides considerations that must be given prior to installing an engineered smoke control system. The pre-installation considerations are:

• Zone operating modes

• Associated equipment

• Equipment supervision

• System testing

• Alarm response

• Automatic smoke control matrix

• Response times

Note:

In this chapter, the application of the smoke control system as a zoned system is for general practice and conforms to national codes and publications. In all cases, the local authority having jurisdiction (AHJ) has the authority to modify requirements.

IMPORTANT

The local AHJ must approve the proposed system before installation begins.

Zone operating modes

Zone operating modes are a pre-installation consideration. The design of a building smoke control system is the responsibility of the building architects and engineers. In the National Fire Protection Association (NFPA) publication NFPA 101 (NFPA 2003, Life Safety Code), chapter

11.8 provides general high rise building requirements. Chapter 12–42 provides high-rise building requirements based on type of occupancy. Both chapters may apply to a specific building.

Understanding the smoke control system operating modes enables the effective layout of system controls. One of four operating modes governs each zone: normal, alarm, adjacent, or unaffected.

BAS-APG001-EN 19

Chapter 2 Pre-installation considerations

Normal mode

A zone is in normal mode when no fire, smoke, or sprinkler alarms are present in the building. In some zoning systems, a zone may be in normal mode if an alarm condition is present in the building but the zone is not affected. In normal mode, the smoke control system is inactive.

Alarm mode

A zone is in alarm mode when it is the origin of the first fire, smoke, or sprinkler alarm. In alarm mode, the smoke control system operates fans and dampers to protect adjacent and unaffected zones and provide a smoke exhaust route for the alarm zone.

Adjacent mode

A zone is in adjacent mode when it is next to the alarm zone. However, in some zoning systems, zones that are not next to the alarm zone may be designated as adjacent zones. Other zoning systems may designate all non-alarm zones as adjacent zones. Codes do not state which zones are adjacent. In adjacent mode, the smoke control system sets fans and dampers to pressurize adjacent zones in order to contain the smoke in the alarm zone.

Unaffected mode

A zone is in unaffected mode when it is neither the alarm zone nor an adjacent zone and an alarm is present in the building. In large buildings, there may be many zones that are not near the alarm zone. Codes do not state which zones are unaffected. In unaffected mode, the smoke control system may shut down and isolate unaffected zones. Or, the smoke control system may allow unaffected zones to operate in normal mode. Actual system operation depends on the design of the smoke control system.

Associated equipment

Equipment associated with the smoke control system design is a preinstallation consideration prior to setting up the smoke control system controls. Associated equipment includes: fire alarm system equipment, fire alarm control panel, firefighter’s smoke control station, and smoke control system equipment.

Fire alarm system equipment

The building fire alarm system is responsible for detecting an alarm condition, alerting occupants by audible and visual means, and signaling the smoke control system. Fire alarm system equipment includes: area,

20 BAS-APG001-EN

Associated equipment

beam, and duct smoke detectors; manual pull stations; and sprinkler flow devices.

Note:

Fire alarm system equipment is neither furnished nor installed by Trane.

Area smoke detectors

Area smoke detectors detect the presence of smoke at the ceiling. When activated, an area smoke detector signals the fire alarm system. The zoning of area smoke detectors must reflect the zoning of the building.

Note:

Under certain conditions, heat detectors or heat with rate of rise detectors are preferable to area smoke detectors.

Beam smoke detectors

Beam smoke detectors detect the presence of smoke beneath the ceiling. When activated, a beam smoke detector signals the fire alarm system. In atrium applications, beam detectors may replace area smoke detectors. Beam smoke detectors minimize interference problems created by stratified hot air under the atrium ceiling.

Duct smoke detectors

Duct smoke detectors detect smoke in building air-distribution system ductwork. When smoke is present, a signal from the detector deactivates the fans in the system in which the detector is installed. However, smoke

control system commands must override fan deactivation by a duct smoke detector.

In NFPA 90A (NFPA 2002, Standard for the Installation of Air Conditioning and Ventilating Systems), section 6.4.2.1 provides the

requirements for duct smoke detectors. Supply duct smoke detectors must be located downstream of the system filters and ahead of any branch connection. In mixing systems, this is usually after the return air connection. Duct smoke detectors may be required in the supply duct of all air-handling systems greater than 2000 cubic feet per minute (CFM) and at each floor with a return air volume greater than 15,000 CFM.

Two exceptions limit the use of duct smoke detectors:

• Duct smoke detectors are not required in 100% exhaust air systems.

• Duct smoke detector use is limited if area smoke detectors cover the

entire space served by the return air distribution. Since area smoke detectors usually cover entire floors, the typical system only requires one duct smoke detector in the common return duct.

Manual pull stations

Manual pull stations enable occupants to report a fire. When activated, a manual pull station signals the fire alarm system. A manual pull station alarm must not initiate the automatic operation of the smoke control

BAS-APG001-EN 21

Chapter 2 Pre-installation considerations

system, since a pull station is not necessarily activated in the zone that contains the smoke or fire.

Sprinkler flow devices

Fire alarm system equipment may include two types of sprinkler flow devices: sprinkler flow switches and tamper switches.

Sprinkler flow switches, installed in fire sprinkler lines, notify the fire alarm control panel (FACP) of flow in the sprinkler lines. The FACP transmits an alarm to the smoke control system. The smoke control system may initiate automatic smoke control from the alarm. Sprinkler zones must coincide with the zone layout of the building and the zoning of the FACP.

Tamper switches are installed on manual shutoff valves in the fire sprinkler system. The switches provide a supervisory alarm signal to the fire alarm system if the shutoff valve closes. Alarms activated by tamper switches must not initiate the automatic operation of the smoke control system.

Fire alarm control panel

The FACP receives alarm signals. If the FACP receives an alarm, it notifies the smoke control system of the alarm and the alarm location. The zone layout of the FACP must match the zone layout of the building to ensure that the FACP is capable of sending accurate signals to the smoke control system. The mechanical and electrical consulting engineers coordinate the building zone layout to the FACP layout to ensure a proper interface.

Firefighter’s smoke control station

The firefighter’s smoke control station (FSCS) enables firefighters to take manual control of the smoke control system. The FSCS must be located in an easily accessible but secure location. The normal location is near the FACP.

IMPORTANT

The FSCS must be listed by Underwriters Laboratories (UL) as suitable for enabling firefighters to take manual control of the smoke control system.

Commands from the FSCS control panel are the highest priority commands in the system. They override automatic control of smoke control system components.

The FSCS provides a graphic representation of the building. It shows smoke control zones and associated smoke control mechanical equipment. The panel includes: lights, an audible trouble LED, and manual switches.

22 BAS-APG001-EN

Associated equipment

Lights

The FSCS provides lights that show the mode of each zone and the status of each piece of smoke control mechanical equipment. The status lights must conform to a specific color code scheme (

Table 3).

Table 3. Pilot lamp color codes

Color Description

Green Fan On or damper Open

Red Fan Off or damper Closed

Yellow (or Amber) Verification of Operation Status light. Fan or

damper not in commanded position.

Audible trouble indicator

The FSCS may provide an audible trouble indicator with a silence switch. If provided, the indicator alerts personnel to system trouble.

Manual switches

The FSCS provides manual switches that operate smoke control system fans and dampers. Normally, there is one manual switch for each piece of equipment. However, in complex smoke control systems that have very large fan systems, one switch may operate more than one piece of equipment. This allows the smoke control system to coordinate smoke control functions without damaging equipment. For example, the manual switches that control large central fan systems may also operate the mixing dampers to prevent tripping the high- and low-pressure cutouts.

Manual switches at the FSCS are either 2- or 3-position switches. Labels show the current state of each switch (

Table 4).

BAS-APG001-EN 23

ON-OFF Fans only controlled from the FSCS

OPEN-CLOSE Dampers only controlled from the FSCS

Smoke control system equipment

The smoke control system receives alarm signals from the FACP and manual command signals from the FSCS. On receiving alarm signals and/or manual commands, the smoke control system controls the mechanical smoke control equipment. Manual command signals from the FSCS take priority over alarm signals.

Chapter 2 Pre-installation considerations

The smoke control system controls fans and positions dedicated and nondedicated dampers, both in the smoke control zones and at the airhandling systems. It may also position dampers or air modulation devices such as variable-air-volume (VAV) boxes serving the smoke control zones. Equipment associated with the smoke control system includes: dampers, fans, verification of operation equipment, and the Tracer™ MP581 programmable controller.

For VAV-based systems, there must be some form of duct pressure relief on each floor or in each smoke control zone. In smoke control mode, all return and supply dampers will be set to 100% open. If the VAV dampers are closed when this occurs, the duct pressure may be enough to damage duct work. To avoid this possibility, duct pressure relief dampers, either DDC or mechanically controlled, should be installed in the ductwork for each smoke control zone.

It should be noted that careful sizing of smoke control supply air damper and relief damper is necessary to use smoke purge and protect dampers.

In contrast to a VAV system, it is not necessary to provide separate duct pressure relief in constant volume as this is a form of dedicated smoke purge with supply and return/exhaust dampers already open. Supply dampers should be sized such that any one damper can spill an adequate amount of air.

Outdoor air, return air, relief, and exhaust dampers

A nondedicated comfort control system controls outdoor air, return air, relief, and exhaust dampers. In normal operation, the return damper operates in opposition to the outdoor air damper. However, during smoke control system activation, all three dampers may be closed simultaneously to isolate the air-handling system for smoke control operations.

An elevator shaft damper, located at the top of a hoistway, relieves pressure generated during elevator operation. Since elevator shaft dampers are usually open, the natural stack effect of the building will tend to distribute smoke through the building via the elevator shafts. Some codes require a key-operated switch at the main floor lobby to close the elevator shaft damper. With local approval, this switch can be located at the FSCS.

Smoke dampers

A smoke damper is located in any duct that penetrates a smoke zone perimeter. Smoke dampers that are listed by Underwriters Laboratories (UL) are subject to more stringent leakage tests than are standard control dampers. The listing usually includes the control actuator as part of the smoke damper assembly, but does not include the end switches.

IMPORTANT

Smoke dampers must have a Underwriters Laboratories (UL) listing for smoke control applications (UL 555S).

24 BAS-APG001-EN

Associated equipment

Smoke dampers are ordered as a complete assembly. They are typically two-position dampers and have end switches that indicate the fully open and fully closed position. The switches are installed in the field. Dampers actuate with two types of control: pneumatic actuation and electrical actuation.

Note:

Switches that are part of the actuator do not provide an acceptable indication of actual damper travel. They only show the operation of the actuator and not the actual position of the damper.

For pneumatically actuated smoke dampers, the operating pressure range (spring range) and the normal position of the damper must be specified. Typically, the normal position will be closed (normally closed). The spring range must be high (8–13 lbs) to give the most close-off force.

Uniform Building Code 905.10.2 requires hard drawn, type L, copper pneumatic piping for smoke control system components. The air source must have automatic isolation valves separating it from pneumatic control devices not used for smoke control. Since the smoke control system will open and close smoke dampers, it may require an air pressure monitoring switch. If air pressure is lost in the smoke damper control lines, the switch transmits a Trouble indication.

For electrically actuated smoke dampers, the operating voltages are 24

Vac a nd 12 0 Vac. It is usually not possible to get actuators with DC operating voltages. A spring on the actuator positions the damper if power is lost. The power-loss position is typically the actuator closed (normally closed) position.

The electrical power that operates the smoke damper must be from an emergency power source and is monitored at a point after the last disconnect. The loss of electrical power initiates a Trouble indication.

BAS-APG001-EN 25

Fans

Fans need additional control components for smoke control operation. Supply/return fan systems require independent control of fans. Multiple fan system Start and Stop points bypass some safety devices.

VAV systems require the smoke control system to be capable of either commanding the fans to full capacity or a higher capacity than comfort controls would command. High-pressure safeties are not bypassed in smoke control operation. Care must be taken to ensure that increased capacities do not trip high-pressure cutout devices. Excess pressures could deactivate fan systems, making them unusable for smoke control.

Verification of operation equipment

Codes require that the smoke control system provide verification of operation status indications at the FSCS. To accomplish this, the smoke control system provides devices that monitor the actual operation of fans

Chapter 2 Pre-installation considerations

and dampers: status switches, differential pressure switches, airflow paddle switches, current-sensing relays, limit switches, and end switches.

Status switches at fans and dampers monitor the operation of the devices. Multiple binary inputs at the Tracer MP581s verify the On and Off status of fans and the Open and Closed status of dampers. If a status switch does not confirm the commanded (automatic or manual) operation, a Fail indicator activates at the FSCS. Failure detection must incorporate a time delay to give the devices time to function.

Differential pressure switches, airflow paddle switches, and currentsensing relays monitor fan operations. Differential switches piped across fan and paddle switches in the air stream can give erroneous indications.

IMPORTANT

A current-sensing relay is the preferred way to confirm the operating status of a fan.

Limit switches and end switches monitor dampers. The switches activate damper Open and Closed signals for the FSCS. The damper blades activate the switches. Some codes require two switches in order to sense both the fully opened and fully closed position of the damper.

Tracer MP581 programmable controller

The Tracer MP581 must have multiple binary inputs to verify the On and Off operation of fans. It must also have multiple binary inputs to verify the Open and Closed positions of dampers.

Equipment supervision

Equipment supervision is a pre-installation consideration. Smoke control equipment must be supervised to ensure it is operational. Supervision techniques consist of confirming communications among system control panels, confirming operation in normal use situations, and performing weekly self-tests.

Confirming communications among all system control panels is a supervision technique that monitors basic system integrity. If any panel loses its communications, a Trouble alert is sent to the FSCS.

Normal use operations confirm the integrity of field point wiring for nondedicated equipment. Nondedicated equipment provides conditioned air to the building daily. When nondedicated equipment is not operational, comfort conditions deteriorate and building tenants notify maintenance personnel.

26 BAS-APG001-EN

System testing

System testing is a pre-installation consideration. To verify proper operation, the smoke control system must include provisions for: automatic weekly self-testing and manual periodic testing.

Automatic weekly self-testing

As UL requires, the smoke control system provides automated weekly self-tests for dedicated smoke control system components. The self-tests activate components and monitor operation. They provide verification of operation status indications to the FSCS that show if the component passed or failed the test. Automatic weekly self-tests do not function if a smoke or fire alarm is present.

Manual periodic testing

As NFPA 92A (NFPA 2000, Recommended Practice for Smoke Control Systems), chapter 5.4 requires, the smoke control system provides a

manual testing capability. It provides annual tests for nondedicated system components and semi-annual tests for dedicated system components. The semi-annual tests are required in addition to the automated weekly self-tests for dedicated smoke control system components. Building maintenance personnel schedule and conduct the tests.

The manual periodic tests verify smoke control system responses to alarm zone inputs. Some of the manual testing must be performed with the system operating on emergency power, if applicable. An alarm must be generated in each zone. The system and equipment responses must be verified and recorded. Manual periodic testing should occur when the building is not occupied.

BAS-APG001-EN 27

Alarm response

Alarm response is a pre-installation consideration. NFPA 92A (NFPA 1996, Recommended Practice for Smoke Control Systems), section 3.4.5.5 requires the automatic response to an alarm to be based on the location of the first alarm. Subsequent alarms from other zones must be ignored for the purposes of automatic response.

Automatic smoke control matrix

An automatic smoke control matrix (Table 5 on page 28, dedicated; Table 6 on page 28, nondedicated) shows each piece of mechanical equipment and each building zone. The matrix shows the automatic response of each piece of equipment to an initial alarm for each smoke zone. It also shows the mode of each zone based on an alarm in another zone. Commands from the FSCS may override the automatic responses. The matrix must be engineered for a specific project.

Response times

Response times are a pre-installation consideration. For a discussion of response time requirements for smoke control systems, refer to NFPA 92A (NFPA 2000, Recommended Practice for Smoke Control Systems), section 3.4.3.3 and NFPA 92B (NFPA 2000, Guide for Smoke Management Systems in Malls, Atria, and Large Areas), section 4.4.4. The activation sequence should be accomplished so as to avoid damage to the equipment. For example, the dampers should be opened before starting the fans. Table 7 shows the required response times, as published in the referenced NFPA documentation.

Ta b l e 7. NFPA response time requirements

Component Response time

Damper operation to desired state (open or closed)

Fan operation to desired state (on or off)

Note:

Some building codes such as the Uniform Building Code have much more stringent response times. As with all of the considerations discussed in this chapter, the local authority having jurisdiction (AHJ) has the final word.

75 seconds

60 seconds

Cable distance considerations

Table 8 on page 30 given cabling distance requirements for data of two different types:

• Hardware based, such as from analog or binary inputs and outputs

• Communication based, such as from the Lontalk communication link

or I/O bus (EX2)

The table also presents different cabling distance requirements depending on whether the data path is monitored or unmonitored.

There are no stated distance limitations for monitored information paths. The maximum distance allowed is the same as the manufacturer’s stated maximum distance for that particular data type. A data path is considered monitored if some notification for opens, ground-shorts, and conductor shorts is available and used (NFPA 72A [2002] section 4.4.7.1).

BAS-APG001-EN 29

Chapter 2 Pre-installation considerations

Note:

Process verification, sometimes referred to as end-to-end testing, can be considered a means of monitoring data (NFPA 92A [2000] section

3.4.6). Communicated values are an example of process verification. A communication link can be monitored for quality, and the system can be notified if there is a communications failure.

Distance limitations for unmonitored data paths are severely limited.

Table 8. Cabling practices and restraints

Monitored data paths

Refer to the best wiring practices given in BMTX-SVN01A-EN for installing Lontalk communication links.

Refer to the wiring requirements given in CNT-SVN01C-EN for the I/O bus wiring between the Tracer MP580/581 and the EX2s.

Unmonitored data paths

3 ft (1 m) (NFPA 72A [2002] section 6.15.2.2)

20 ft (6 m) and in conduit (NFPA 72A [2002] section 4.4.7.1.8)

Smoke control system overview

An engineered smoke control system can be added on to a Tracer Summit requirements, and capacities for smoke control applications differ from Tracer Summit systems that do not employ smoke control.

A smoke control installation includes a Trane building control unit (BCU), the Tracer MP581 programmable controller, and wiring. These devices should be wired on the smoke control communication link. Devices that are a part of the Tracer Summit system, but are not used by the smoke control system, must be on a separate communication link.

IMPORTANT

For dedicated smoke control system, only Tracer MP581s used for smoke control are allowed on the LonTalk communication link. Tracer MP581s and other LonTalk UCMs not involved in smoke control must be connected to other BCUs. A nondedicated smoke control system can have other LonTalk devices connected to the communication link.

Installation diagrams consist of system riser and system termination diagrams. These diagrams provide requirements and restrictions to the installer.

BAS-APG001-EN 31

32 BAS-APG001-EN

System termination diagrams

System termination diagrams show wire terminations at panels and field devices. Guidelines for creating system termination diagrams include:

• Diagrams for Tracer MP581 panels may be formatted as lists.

• Diagrams for field devices show: normal state, expected operation,

and voltage requirements. An example of a normal state notation is

normally open. An example of an expected operation description is closed contact opens damper.

• Diagrams for field devices not furnished by Trane are created during

installation. After installation, the diagrams become part of the asbuilt documentation.

• Diagrams for the control of starters and variable flow devices (VFDs)

must show the required relays and connections for the hierarchy of control ( to bypass some safety devices and the local manual switches. Also, manual controls from the firefighter’s smoke control station (FSCS) must be wired to give them the highest priority of control.

System termination diagrams

The wiring between a Tracer MP581 and the FSCS is non-supervised and power limited. Additional requirements are:

• Tracer MP581 and FSCS must be in the same room.

• Wiring between the Tracer MP581 and FSCS must be in conduit.

• Wiring distance cannot exceed 20 ft.

• Wire must be #18 AWG.

The number of wires needed between the Tracer MP581(s) and the FSCS is determined by the total number of zones and manual override switches at the FSCS. Multiple Tracer MP581 panels may be required to monitor and control the FSCS. One Tracer MP581 controls the trouble LED and the Sonalert audible alarm of the FSCS, as well as supplying 24 Vac power to operate the lamp test relay(s).

Table 9 shows wires for a typical Tracer MP581 that controls the FSCS trouble LED and the Sonalert audible alarm.

Table 12. BMTX BCU model number

Model Description

BMTX001DAB000 BMTX BCU, 120 Vac, UUKL listed

To ensure proper operation of the BMTX BCU, install the power supply circuit in accordance with the following guidelines:

• The BCU must receive power from a dedicated power circuit. Failure

to comply may cause control malfunctions.

• A disconnect switch for the dedicated power circuit must be near the

controller, within easy reach of the operator, and marked as the dis connecting device for the controller.

• High-voltage power-wire conduits or wire bundles must not contain

input/output wires. Failure to comply may cause the controller to mal function due to electrical noise.

• High-voltage power wiring must comply with the National Electrical

Code (NEC) and applicable local electrical codes.

• High-voltage wiring requires three-wire 120/230 Vac service (line,

neutral, ground).

Note:

The transformer voltage utilization range is 120 Vac. T h e pane l automatically detects whether the current is 50 or 60 cycle.

To connect high-voltage power wires:

WARNING

EMI/RFI considerations

Take care to isolate HVAC controllers from electromagnetic interference (EMI) and radio frequency interference (RFI). Such interference can be caused by radio and TV towers, hospital diagnostic equipment, radar equipment, electric power transmission equipment, and so on. In addi tion, take care to prevent the BMTX BCU from radiating EMI and/or RFI.

The BMTX BCU is equipped with EMI/RFI filters that trap RFI to ground. In most situations, a good earth ground will reduce EMI/RFI problems by acting as a drain for EMI and RFI. If the BMTX BCU is receiving or radiating interference, make sure that the earth ground is good. Do not assume that the building conduit is an adequate ground.

Checking the earth ground

Though a proper earth ground is especially important in areas of high EMI or RFI, always check the quality of the ground, regardless of location.

WARNING Hazardous voltage!

The cover plate must be in place when the BCU is operating. Failure to replace the cover plate could result in death or serious injury.

If the earth ground has a voltage of more than 4 Vac, use a different ground. Failure to do so could result in death or serious injury.

To check the quality of the earth ground:

1. Open the enclosure door.

2. Inside of the enclosure at the top-right corner, remove the high-voltage area cover plate.

3. Measure the ac voltage between the earth ground and the neutral terminal, as shown in Figure 20 on page 47.

Ideally, the voltage should be 0 Vac. Find a different ground if the voltage exceeds 4 Vac. A higher voltage may result in:

• Danger to people touching the enclosure

• Erratic communications

• Erratic equipment operation (Because noise may affect voltage

levels at the inputs—the controller interprets input noise as changes in temperature, humidity, pressure, and so on.)

4. Replace the cover plate.

Installing the Tracer MP581 programmable controller

Installation guidelines

Guidelines for installing a Tracer MP581 include:

• A Tracer MP581 that monitors the fire alarm control panel for

consistency (FACP) must be installed in the same room as the FACP. It must be installed within 20 feet of the FACP. Cables between the FACP and the Tracer MP581 must be in conduit.

• A Tracer MP581 that monitors and controls the fire smoke control

system (FSCS) must be installed in the same room as the FSCS. It must be installed within 20 feet of the FSCS. Cables between the FACP and Tracer MP581 must be in conduit.

▲IMPORTANT

Wiring between the Tracer MP581 and the FACP and between the Tracer MP581 and the FSCS (point wiring) must be in conduit. The conduit requirement is necessary, since the binary inputs to the Tracer MP581 are not supervised.

• Wiring from a Tracer MP581 to field sensors and relays is not

supervised. Installation of this wiring must conform to more stringent requirements when a Tracer MP581 is part of a smoke control system than when it is part of a standard mechanical system control.

Circuit requirements

To ensure proper operation of the Tracer MP581, install the power supply circuit in accordance with the following guidelines:

• The Tracer MP581 must receive high-voltage power from a dedicated

power circuit. Failure to comply may cause control malfunctions.

• A disconnect switch for the dedicated power circuit must be near the

controller, within easy reach of the operator, and marked as the dis connecting device for the controller.

• High-voltage power-wire conduits or wire bundles must not contain

input/output wires. Failure to comply may cause the controller to mal function due to electrical noise.

• High-voltage power wiring must comply with the National Electrical

Code (NEC) and applicable local electrical codes.

• High-voltage power wiring requires three-wire 120/230 Vac service.

Use copper conductors only.

Note:

The voltage utilization range for the Tracer MP581 transformer is 120 Vac. The panel detects whether the current is 50 or 60 cycle.

WARNING Hazardous voltage!

Before making electrical connections, lock open the supply-power disconnect switch. Failure to do so could result in death or serious injury.

CAUTION Use copper conductors only!

Unit terminals are designed to accept copper conductors only. Other conductors may cause equipment damage.

To connect high-voltage power wires:

1. Lock open the supply-power disconnect switch.

2. At the top right corner of the enclosure, remove the knockout and install 0.5-inch (13 mm) conduit (see

Figure 29. Knockout for high-voltage power wires

Figure 29).

Power wire entry through knockout for 0.5-inch conduit

3. Open or remove the Tracer MP581 door if it is already installed.

4. Inside of the enclosure at the top-right corner, remove the high-voltage area cover plate.

5. Feed the high-voltage power wires into the enclosure.

6. Connect the line wire to the L terminal as shown in Figure 30 on page

61.

7. Connect the neutral wire to the N terminal.

8. Connect the green ground wire to the chassis ground screw. The ground wire must be continuous back to the circuit-breaker panel.

9. Replace the cover plate.

WARNING Hazardous voltage!

The cover plate must be in place when the controller is operating. Failure to replace the cover plate could result in death or serious injury.

10. On a label, record the location of the circuit-breaker panel and the electrical circuit. Attach the label to the cover plate.

Chapter 5 Installing the Tracer MP581 programmable controller

EMI/RFI considerations

The Tracer MP581 is equipped with EMI/RFI filters that trap RFI to ground. In most situations, a good earth ground will reduce EMI/RFI problems by acting as a drain for EMI and RFI. If the Tracer MP581 is receiving or radiating interference, make sure that the earth ground is good. Do not assume that the building conduit is an adequate ground.

Checking the earth ground

Though a proper earth ground is especially important in areas of high EMI or RFI, always check the quality of the ground, regardless of location.

WARNING

Hazardous voltage!

The cover plate must be in place when the controller is operating. Failure to replace the cover plate could result in death or serious injury.

If the earth ground has a voltage of more than 4 Vac, use a different ground. Failure to do so could result in death or serious injury.

To check the quality of the earth ground:

1. Open the enclosure door.

2. Inside of the enclosure at the top-right corner, remove the high-voltage area cover plate.

3. Measure the ac voltage between the earth ground and the neutral terminal, as shown in Figure 31 on page 63.

Ideally, the voltage should be 0 Vac. Find a different ground if the voltage exceeds 4 Vac. A higher voltage may result in:

• Danger to people touching the enclosure

• Erratic communications

• Erratic equipment operation (Because noise may affect voltage

levels at the inputs—the controller interprets input noise as changes in temperature, humidity, pressure, and so on.)

4. Replace the cover plate.

Input/output wiring guidelines

Input/output wiring must meet the following guidelines:

• Wiring must conform with the National Electrical Code and local elec-

trical codes.

• Use only 18 AWG twisted-pair wire with stranded, tinned-copper con-

ductors.

• Binary input/output wires must not exceed 1,000 ft (300 m).

• Analog input wires must not exceed 300 ft (100 m) for thermistors

and 0–10 Vdc inputs and 1,000 ft (300 m) for 0–20 mA inputs.

• Analog output wires must not exceed 1,000 ft (300 m) for 0–10 Vdc

outputs and 0–20 mA outputs.

• Do not run input/output wires in the same wire bundle with high-

voltage power wires. Running input/output wires with 24 Vac power wires is acceptable, but the input wire must be shielded.

• Terminate input/output wires before installing the main circuit board

(see

“Installing the circuit board” on page 76).

Checking binary inputs

To check binary inputs for proper operation:

1. Make sure that the sensor is connected and closed.

2. Set the multi-meter to measure Vac, then measure the voltage across the input connections at the signal and common screw terminals.

The measured voltage should be less than 0.1 Vac. If the voltage is greater than this, the input readings may change erratically.

3. Set the multi-meter to measure Vdc, then measure the voltage across the input at the signal and common screw terminals.

The measured voltage should be less than 0.1 Vdc. If the voltage is greater than this, the input readings may be offset.

CAUTION Equipment damage!

Continue to step 4 only if you completed steps 2 and 3 successfully. Measuring resistance may damage the meter if the voltage is too high.

4. Set the multi-meter to measure resistance. If you completed steps 2 and 3 successfully, measure the resistance across the input.

The resistance should be less than 200 Ω when the binary input is closed and greater than 1 kΩ when it is open.

70 BAS-APG001-EN

Checking outputs

Follow the procedures in this section to test outputs for proper operation.

IMPORTANT

Perform the tests in this section before providing power to the termination board or installing the main circuit board. Failure to do so will result in incorrect multi-meter readings.

To test outputs for proper operation, you need the following tools:

• Digital multi-meter

• Small flat-tip screwdriver

Checking binary outputs

To check binary outputs for proper operation:

1. Set the multi-meter to measure Vac, then measure the voltage across the binary output at the common and signal screw terminals.

The measured voltage should be less than 0.1 Vac. If the voltage is greater than this, the load may turn on and off unexpectedly. Check for the following problems:

• A shared power supply may be incorrectly connected. Check the

wire to make sure that no additional connections have been made.

• The wire may have an induced voltage somewhere along its

length.

2. Set the multi-meter to measure Vdc, then measure the voltage across the binary output at the common and signal screw terminals.

The measured voltage should be less than 0.1 Vdc. If the it is greater than this, a shared power supply may be incorrectly connected. Check the wire to make sure that no additional connections have been made.

CAUTION Equipment damage!

Continue to step 3 only if you completed steps 1 and 2 successfully. Measuring resistance may damage the meter if the voltage is too high.

3. Set the multi-meter to measure resistance. If you completed steps 1 and 2 successfully, measure the resistance across the binary output to confirm that there are no shorts and no open circuits.

Resistance is load dependent. Pilot relays have a relatively low resistance of less than 1 kΩ, but some actuators have a high resistance. Check to see what kind of binary output is connected before checking for open and short circuits.

BAS-APG001-EN 71

Checking 0–10 Vdc analog outputs

To check 0–10 Vdc analog outputs for proper operation:

Chapter 5 Installing the Tracer MP581 programmable controller

1. Make sure that the actuator is connected but powered off.

2. Set the multi-meter to measure Vac, then measure the voltage across the analog output at the signal and common screw terminals.

The measured voltage should be less than 0.1 Vac. If the voltage is greater than this, the load may turn on and off unexpectedly. Check for the following problems:

• A shared power supply may be incorrectly connected. Check along

the wire to make sure that no additional connections have been made.

• The wire may have an induced voltage somewhere along its

length.

3. Set the multi-meter to measure Vdc, then measure the voltage across the analog output at the signal and common screw terminals.

The measured voltage should be less than 0.1 Vdc. If the voltage is greater than this, a shared power supply may be incorrectly con nected. Check along the wire to make sure that no additional connections have been made.

CAUTION

Equipment damage!

Continue to step 4 only if you completed steps 2 and 3 successfully. Measuring resistance may damage the meter if the voltage is too high.

4. Set the multi-meter to measure resistance. If you completed steps 2 and 3 successfully, measure the resistance across the analog output at the signal and common screw terminals.

The resistance should be greater than 500 Ω. (The analog output will not be able to reach 10 Vdc if the load resistance is less than 500 Ω

Checking 0–20 mA analog outputs

To check 0–20 mA analog outputs for proper operation:

1. Make sure that the actuator is connected but powered off.

2. Set the multi-meter to measure Vac, then measure the voltage across the analog output at the signal and common screw terminals.

The measured voltage should be less than 0.1 Vac. If the voltage is greater than this, the load may turn on and off unexpectedly. Check for the following problems:

• A shared power supply may be incorrectly connected. Check along
