Fire Alarm & Emergency Communication System Limitations

While a life safety system may lower insurance rates, it is not a substitute for life and property insurance!

An automatic fire alarm system—typically made up of smoke
detectors, heat detectors, manual pull stations, audible warning
devices, and a fire alarm control panel (FACP) with remote notifi­cation capability—can provide early warning of a developing fire.
Such a system, however, does not assure protection against
property damage or loss of life resulting from a fire.

An emergency communication system—typically made up of
an automatic fire alarm system (as described above) and a life
safety communication system that may include an autonomous
control unit (ACU), local operating console (LOC), voice commu­nication, and other various interoperable communication meth­ods—can broadcast a mass notification message. Such a
system, however, does not assure protection against property
damage or loss of life resulting from a fire or life safety event.

The Manufacturer recommends that smoke and/or heat
detectors be located throughout a protected premises following
the recommendations of the current edition of the National Fire
Protection Association Standard 72 (NFPA 72), manufacturer's
recommendations, State and local codes, and the
recommendations contained in the Guide for Proper Use of
System Smoke Detectors, which is made available at no charge
to all installing dealers. This document can be found at http://
www.systemsensor.com/appguides/. A study by the Federal
Emergency Management Agency (an agency of the United
States government) indicated that smoke detectors may not go
off in as many as 35% of all fires. While fire alarm systems are
designed to provide early warning against fire, they do not
guarantee warning or protection against fire. A fire alarm system
may not provide timely or adequate warning, or simply may not
function, for a variety of reasons:

Smoke detectors may not sense fire where smoke cannot reach
the detectors such as in chimneys, in or behind walls, on roofs,
or on the other side of closed doors. Smoke detectors also may
not sense a fire on another level or floor of a building. A second­floor detector, for example, may not sense a first-floor or base­ment fire.

Particles of combustion or “smoke” from a developing fire
may not reach the sensing chambers of smoke detectors
because:

• Barriers such as closed or partially closed doors, walls, chim­neys, even wet or humid areas may inhibit particle or smoke
flow.

• Smoke particles may become “cold,” stratify, and not reach
the ceiling or upper walls where detectors are located.

• Smoke particles may be blown away from detectors by air
outlets, such as air conditioning vents.

• Smoke particles may be drawn into air returns before reach­ing the detector.

The amount of “smoke” present may be insufficient to alarm
smoke detectors. Smoke detectors are designed to alarm at var­ious levels of smoke density. If such density levels are not cre­ated by a developing fire at the location of detectors, the
detectors will not go into alarm.

Smoke detectors, even when working properly, have sensing lim­itations. Detectors that have photoelectronic sensing chambers
tend to detect smoldering fires better than flaming fires, which
have little visible smoke. Detectors that have ionizing-type sens­ing chambers tend to detect fast-flaming fires better than smol­dering fires. Because fires develop in different ways and are
often unpredictable in their growth, neither type of detector is
necessarily best and a given type of detector may not provide
adequate warning of a fire.

Smoke detectors cannot be expected to provide adequate warn­ing of fires caused by arson, children playing with matches
(especially in bedrooms), smoking in bed, and violent explosions

(caused by escaping gas, improper storage of flammable materi­als, etc.).

Heat detectors do not sense particles of combustion and alarm
only when heat on their sensors increases at a predetermined
rate or reaches a predetermined level. Rate-of-rise heat detec­tors may be subject to reduced sensitivity over time. For this rea­son, the rate-of-rise feature of each detector should be tested at
least once per year by a qualified fire protection specialist. Heat
detectors are designed to protect property, not life.

IMPORTANT! Smoke detectors must be installed in the same
room as the control panel and in rooms used by the system for
the connection of alarm transmission wiring, communications,
signaling, and/or power. If detectors are not so located, a devel­oping fire may damage the alarm system, compromising its abil­ity to report a fire.

Audible warning devices such as bells, horns, strobes,
speakers and displays may not alert people if these devices

are located on the other side of closed or partly open doors or
are located on another floor of a building. Any warning device
may fail to alert people with a disability or those who have
recently consumed drugs, alcohol, or medication. Please note
that:

• An emergency communication system may take priority over
a fire alarm system in the event of a life safety emergency.

• Voice messaging systems must be designed to meet intelligi­bility requirements as defined by NFPA, local codes, and
Authorities Having Jurisdiction (AHJ).

• Language and instructional requirements must be clearly dis­seminated on any local displays.

• Strobes can, under certain circumstances, cause seizures in
people with conditions such as epilepsy.

• Studies have shown that certain people, even when they hear
a fire alarm signal, do not respond to or comprehend the
meaning of the signal. Audible devices, such as horns and
bells, can have different tonal patterns and frequencies. It is
the property owner's responsibility to conduct fire drills and
other training exercises to make people aware of fire alarm
signals and instruct them on the proper reaction to alarm sig­nals.

• In rare instances, the sounding of a warning device can cause
temporary or permanent hearing loss.

A life safety system will not operate without any electrical
power. If AC power fails, the system will operate from standby
batteries only for a specified time and only if the batteries have
been properly maintained and replaced regularly.

Equipment used in the system may not be technically compat­ible with the control panel. It is essential to use only equipment
listed for service with your control panel.

Telephone lines needed to transmit alarm signals from a prem­ises to a central monitoring station may be out of service or tem­porarily disabled. For added protection against telephone line
failure, backup radio transmission systems are recommended.

The most common cause of life safety system malfunction is
inadequate maintenance. To keep the entire life safety system in
excellent working order, ongoing maintenance is required per the
manufacturer's recommendations, and UL and NFPA stan­dards. At a minimum, the requirements of NFPA 72 shall be fol­lowed. Environments with large amounts of dust, dirt, or high air
velocity require more frequent maintenance. A maintenance
agreement should be arranged through the local manufacturer's
representative. Maintenance should be scheduled monthly or as
required by National and/or local fire codes and should be per­formed by authorized professional life safety system installers
only. Adequate written records of all inspections should be kept.

Installation Precautions

Adherence to the following will aid in problem-free installation with long-term reliability:

WARNING - Several different sources of power can be
connected to the fire alarm control panel. Disconnect all

sources of power before servicing. Control unit and associ­ated equipment may be damaged by removing and/or insert­ing cards, modules, or interconnecting cables while the unit is
energized. Do not attempt to install, service, or operate this
unit until manuals are read and understood.

CAUTION - System Re-acceptance Test after Software
Changes: To ensure proper system operation, this product

must be tested in accordance with NFPA 72 after any pro­gramming operation or change in site-specific software. Re­acceptance testing is required after any change, addition or
deletion of system components, or after any modification,
repair or adjustment to system hardware or wiring. All compo­nents, circuits, system operations, or software functions known
to be affected by a change must be 100% tested. In addition,
to ensure that other operations are not inadvertently affected,
at least 10% of initiating devices that are not directly affected
by the change, up to a maximum of 50 devices, must also be
tested and proper system operation verified.

This system meets NFPA requirements for operation at 0-49º
C/32-120º F and at a relative humidity 93% ± 2% RH (non­condensing) at 32°C ± 2°C (90°F ± 3°F). However, the useful
life of the system's standby batteries and the electronic com­ponents may be adversely affected by extreme temperature
ranges and humidity. Therefore, it is recommended that this
system and its peripherals be installed in an environment with
a normal room temperature of 15-27º C/60-80º F.

Verify that wire sizes are adequate for all initiating and indi­cating device loops. Most devices cannot tolerate more than a
10% I.R. drop from the specified device voltage.

Like all solid state electronic devices, this system may
operate erratically or can be damaged when subjected to light­ning induced transients. Although no system is completely
immune from lightning transients and interference, proper
grounding will reduce susceptibility. Overhead or outside aerial
wiring is not recommended, due to an increased susceptibility
to nearby lightning strikes. Consult with the Technical Ser­vices Department if any problems are anticipated or encoun­tered.

Disconnect AC power and batteries prior to removing or
inserting circuit boards. Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filing,
reaming, or punching of the enclosure. When possible, make
all cable entries from the sides or rear. Before making modifi­cations, verify that they will not interfere with battery, trans­former, or printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs. Over­tightening may damage threads, resulting in reduced terminal
contact pressure and difficulty with screw terminal removal.

This system contains static-sensitive components.
Always ground yourself with a proper wrist strap before han­dling any circuits so that static charges are removed from the
body. Use static suppressive packaging to protect electronic
assemblies removed from the unit.

Follow the instructions in the installation, operating, and pro­gramming manuals. These instructions must be followed to
avoid damage to the control panel and associated equipment.
FACP operation and reliability depend upon proper installation.

3.3 Mounting a Cabinet

This section provides instructions for mounting the NFS-320/E/C backbox to a wall. The NFS­320/E/C is assembled with a removable chassis that can be removed to provide easier access to the
backbox’s mounting holes, or to allow the electronics to be worked on outside the cabinet.

Follow these guidelines when mounting the backbox:

• Locate the backbox so that the top edge is 66 inches (1.6764 m) above the surface of the
finished floor.

• Access to the cabinet shall be provided in accordance with NFPA 90, article 110.33.

• Allow sufficient clearance around cabinet for door to swing freely. (See Section 2.2.5 “System
Cabinet”.)

• Use the four holes in the back surface of the backbox to provide secure mounting. (See
Figure 3.1 on page 19.)

• Mount the backbox on a surface that is in a clean, dry, vibration-free area.

CAUTION:

Unless you are familiar with the placement of components within this backbox, only use the knockout
locations provided for conduit entry.

Follow the instructions below:

1. Mark and pre-drill holes for the top two keyhole mounting bolts (0.25 inch, 0.635 cm). Use
mounting hardware appropriate for the mounting surfaces; see UL 2017 Pull-Test
Requirements.

2. Select and punch open the appropriate knock-outs. (For selection guidelines, see Section 3.9
“UL Power-limited Wiring Requirements”.)

3.11.2 Installing and Configuring the PRN Series Printer

When connected to the Control Panel via an EIA-232 interface, the PRN prints a copy of all status
changes within the control panel and time-stamps the printout with the time of day and date the
event occurred. It provides 80 columns of data on standard 9" by 11" tractor-feed paper.

NOTE: You can also use the EIA-232 printer interface with UL-listed information technology
equipment, such as personal computers, to monitor the control panel for supplementary
purposes.

This section contains information on connecting a printer to the control panel and for setting the
printer options.

Connecting a Remote PRN Series Printer

Remote printers require a 120 VAC, 50/60 Hz primary power source. If required for the fire alarm
system configuration (for example, a Proprietary Fire Alarm System), a remote printer requires a
secondary power source (battery backup). Because a secondary power source is not provided, use a
separate Uninterruptable Power Supply (UPS) that is UL-listed for Fire Protective Signaling. You
may use your building emergency power supply, so long as it meets the power continuity
requirements of NFPA 72. Refer to NFPA 72 for further details.

Connect the remote printer to the Control Panel as follows:

1. Connect the three (3) open leads of the custom cable to the TB12 terminal block on the control

2. Plug the DB-25 connector end of the custom cable into the EIA-232 port of the remote printer.

5.1 Acceptance Test

When finished with the original installation and all modifications, conduct a complete operational
test on the entire installation to verify compliance with applicable NFPA standards. Testing should
be conducted by a factory-trained fire alarm technician in the presence of a representative of the
Authority Having Jurisdiction and the owner’s representative. Follow procedures outlined in NFPA
Standard 72’s section on Inspection, Testing and Maintenance.

5.2 Periodic Testing and Service

Periodic testing and servicing of the control panel, all initiating and notification devices, and any
other associated equipment is essential to ensure proper and reliable operation. Test and service the
control panel according to the schedules and procedures outlined in the following documents:

• NFPA Standard 72’s section on Inspection, Testing and Maintenance.

• Service manuals and instructions for the peripheral devices installed in the system. Correct any
trouble condition or malfunction immediately.

5.3 Operational Checks

Between formal periodic testing and servicing intervals, the following operation checks should be
performed monthly, or more frequently when required by the Authority Having Jurisdiction.

• Before proceeding: a) notify the fire department and the central alarm receiving station if
transmitting alarm conditions; b) notify facility personnel of the test so that alarm sounding
devices are disregarded during the test period; and c) when necessary, disable activation of
alarm notification appliances and speakers to prevent their sounding.

• Disconnect all releasing devices to prevent accidental activation in accordance with NFPA
2001 and NFPA 12A releasing agents.

WARNING:

Do not rely on disable/enable software settings to lockout releasing devices.

• Check that the green POWER LED lights.

• Check that all status LEDs are off.

• Press and hold the LAMP TEST key. Verify that all LEDs and all LCD display segments work.

• Activate an Initiating Device Circuit using an alarm initiating device or an addressable
initiating device on the SLC and check that all programmed active notification appliances
function. Reset the alarm initiating device, the control panel, and any other associated
equipment. Select the paging function and confirm that the message can be heard in the
affected fire zones. Repeat the above step with each Initiating Device Circuit and each
addressable device.

• Remove AC power, activate an Initiating Device Circuit through an alarm initiating device or
an addressable initiating device on the SLC, and check that programmed active notification
appliances sound, and alarm indicators illuminate. Measure the battery voltage with
notification appliances active. Replace any battery with a terminal voltage less than 21.6 VDC

to a recent power outage, allow the batteries to charge for 48 hours before testing.

• Return all circuits to their pretest condition.

• Check that all status LEDs are off and the green POWER LED is on.

• Notify fire, central station and/or building personnel when you finish testing the system.

5.4 Battery Checks and Maintenance

Maintenance-free sealed lead-acid batteries used in the system do not require the addition of water
or electrolyte. These batteries are charged and maintained in a fully charged state by the main
power supply’s charger during normal system operation. A discharged battery typically reaches the
voltage of 27.6 VDC within 48 hours; the charge rate depends on the battery size (2.0A for 18­26AH; 5.0A-5.7A for 26AH-200AH).

Immediately replace a leaking or damaged battery. Batteries should be replaced in accordance with
the battery manufacturer’s recommendations.

WARNING:

Batteries contain Sulfuric Acid which can cause severe burns to the skin and eyes and damage to
fabrics.

• If a battery leaks and contact is made with the Sulfuric Acid, immediately flush skin and/or
eyes with water for at least 15 minutes. Water and household baking soda provides a good
neutralizing solution for Sulfuric Acid.

• If Sulfuric Acid gets into eyes, seek immediate medical attention.

• Ensure proper handling of the battery to prevent short circuits.

• Take care to avoid accidental shorting of the leads from uninsulated work benches, tools,
bracelets, rings, and coins.

WARNING:

Shorting the battery leads can damage the battery, equipment, and could cause injury to personnel.

Appendix A: Power Supply Calculations

Calculations must be done to determine standby and alarm DC current loads. Ampere-hour
requirements must be calculated as well to determine battery size.

The CPS-24/E power supply provides filtered 24VDC power that may be used for operating
external devices. Use Table A.2 to determine if external loading is within the capabilities of the
power supply.

A.1 Calculating AC Branch Circuit Current

Use Table A.1 below to determine the total amount of current, in AC amperes, that a 120 VAC,
50/60 Hz service must be able to supply to the fire alarm system. Devices rated for 220-240 VAC
operation will draw approximately one-half the current listed in Table A.1.

ACPS-610 Installation Manuals for battery calculations.

AC Branch Circuit Installation

For guidelines on wiring the AC branch circuit current, see “Operating Power: AC Branch Circuit”
on page 60 in Appendix B.1 “Electrical Specifications”.

A.2 Calculating the System Current Draws

The control panel’s main power supply must be able to power all internal system devices (and
several types of external devices) continuously during non-fire alarm conditions. Use column 1 in
Table A.2 to calculate the Non-Fire Alarm Load on the power supply regulator when applying
primary power. The main power supply must also provide a finite amount of additional current
during a fire alarm condition. Use column 2 in Table A.2 to calculate the additional current needed
during fire alarms. The requirements for non-fire alarm and fire alarm current loads cannot exceed
the capabilities of the power supply as listed below:

• 3.9 A at 24 VDC during Standby; and

• 7.4 A at 24 VDC during Alarm.

The current draw from all NACs plus DC output from TB10 and TB2 is 3.0 A during standby, and

6.0 A in alarm.

52 NFS-320/E/C Installation Manual — P/N 52745:M2 7/1/14

Calculating the System Current Draws Power Supply Calculations

How to Use the Calculating Tables

As used in this section, “Primary” refers to the control panel’s on-board power supply, its primary
source of AC power. “Secondary” refers to the control panel’s backup batteries (or any other 24
VDC power supply listed for Fire Protective Signaling and connected in place of the batteries). The
term “standby” refers to the output current required when no fire alarm is present. The term “alarm”
refers to the output current required when a fire alarm is present.

The Primary Power Source Non-Alarm Current and Alarm Current columns are DC current
calculations. These calculations confirm that the power supply can provide enough current to
support the system during Primary Non-Fire Alarm and Fire Alarm conditions.

Quantities List the number of devices powered by the FACP and its power supply. Devices
powered by the Accessories Output (TB10 and TB2) draw current directly from the panel. Devices
powered by the Panel Output draw current through the fire panel’s connection to the power supply.
Use these quantities to calculate total current draw of each set of devices in calculation columns 1,
2, and 3.

Calculation Column 1 (Primary, Non-Fire Alarm Current in amps) Add the contents of
calculation column 1 to get the current drawn from the power supply during a non-alarm condition,
with AC power applied. This current draw cannot exceed 3.9 A without an auxiliary power supply.

Calculation Column 2 (Primary, Fire Alarm Current in amps) Calculation column 2 lets
the system designer determine the current load that the power supply must support during a fire
alarm. The total current draw during a fire alarm cannot exceed 7.4 A without an auxiliary power
supply.

Typically, a system should contain capacity to activate all output circuits and relays, and support
fire alarms on no less than 10% of Initiating Device Circuits, subject to the requirements of the
Authority Having Jurisdiction (AHJ).

The Control Panel provides power for Notification Appliance Circuits. Refer to the Device
Compatibility Document for 24 VDC notification appliances that are UL- and ULC-listed for fire
alarm systems.

Calculation Column 3 [Secondary (Battery) Non-Alarm Current] Column 3 lets the
system designer calculate the non-fire alarm current drawn from the secondary source in a non-fire
alarm condition during AC power loss.The non-fire alarm current is required to complete the
standby battery calculations. After summing all current draws, insert the total in Table A.3.

A.2.1 Calculating the Maximum Secondary Power Fire Alarm

Current Draw

Use Table A.3 below to determine the maximum current requirements of secondary power source
during fire alarm conditions. The result obtained is the amount of current that the batteries must be
able to supply to the fire alarm system. Use the result in Table A.4 to determine the size of the
batteries needed for the fire alarm system.

Results taken from Table A.3 below assume that, while in a fire alarm condition, batteries must
feed the main power supply (and any additional supplies such as the APS2-6R) with the maximum
rated power each supply can provide.

Electrical Specifications Wire Requirements

Operating Power: AC Branch Circuit

The control panel requires connection to a separate dedicated AC branch circuit. Follow these
guidelines when connecting the AC branch circuit:

• Label the branch circuit “Fire Alarm”. This must be a separate dedicated AC fire alarm circuit.

• Connect the branch circuit to the line side of the main power feed of the protected premises.

• Do not power other equipment from the fire alarm branch circuit.

• Run the AC branch circuit wire continuously, without any disconnect devices except for
overcurrent protection, from the power source to the fire alarm control panel.

• Overcurrent protection for the AC branch circuit must comply with Article 760 of the National
Electrical Codes, as well as local codes.

• Use 12 AWG (3.31 mm

Connect the ground terminal (TB1-Earth) to a solid earth ground (a metallic, cold water pipe may
be suitable in some installations). This connection is vital in reducing the panel’s susceptibility to
transients generated by lightning and electrostatic discharge.

) wire with 600 VAC insulation for the AC branch circuit.

Operating Power: Secondary Power Source (Batteries)

The battery charger is current-limited and can recharge sealed lead-acid type batteries. The battery
charger shuts off when the control panel is in alarm.

B.2 Wire Requirements

Each type of circuit within the Fire Alarm Control System requires use of a specific wire type to
ensure proper circuit operation. The wire gauge of a particular circuit depends on the length of that
circuit and the current traveling through it. Use Table B.1 below to determine the specific wiring
requirements for each circuit.

Compliance with the Federal Communications Commission (FCC) and Canadian Department of
Communication regulations on electrical energy radiation requires the following: Use twisted-pair
shielded wire for any non-SLC-loop wiring entering or exiting the cabinet that is not enclosed in
conduit. Use twisted-pair unshielded wiring for SLC-loop wiring.

NOTE: If running an SLC in conduit with Notification Appliance Circuits, you can reduce
problems by exclusively using electronic sounders (such as the SpectrAlert, SpectrAlert Advanced
or MA/SS-24 Series) instead of more electronically noisy notification appliances (such as
electromechanical bells or horns).
