Fire Alarm System Limitations
While a fire alarm system may lower insurance
rates, it is not a substitute for fire 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 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.
The Manufacturer recommends that smoke and/or heat
detectors be located throughout a protected premise 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 Guides for
Proper Use of System Smoke Detectors, which are made
available at no charge to all installing dealers. These documents can be found at http:/www.systemsensor.com/html/
applicat.html. 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 second-floor 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, or
chimneys 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.
• 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 stor-
age 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, crippling its ability to report
a fire.
Audible warning devices such as bells 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:
• 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 or comprehend the meaning of the signal. It is the property
owner's responsibility to conduct fire drills and other
training exercise 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 fire alarm 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. It is essential to use only
equipment listed for service with your control panel.
Telephone lines needed to transmit alarm signals from
a premise 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 fire alarm malfunction is
inadequate maintenance. To keep the entire fire alarm
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 fire
alarm 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 this manual is read and understood.
CAUTION - System Reacceptance 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 indoor dry
operation at 0-49° C/32-120° F
93 ±2% RH (non-condensing) at 32 ±2° C/90 ±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 all peripherals be
installed in an environment with a nominal room temperature of 15-27° C/60-80° F.
Verify that wire sizes are adequate for all initiating and
indicating device loops. Refer to manual Specifications
section for maximum allowable I.R. drop from the specified
device voltage.
and at a relative humidity of
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
interferences, 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, and printed circuit board
location.
Do not tighten screw terminals more than 9 in-lbs.
Over-tightening 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 by authorized personnel.

System Overview
SECTION 1 System Overview
The FCPS-24FS6 is a 6 amp power supply and the FCPS-24FS8 is an 8 amp power supply. Each
FCPS-24FS power supply is a compact, cost-effective, remote power supply and battery charger
which provides ADA compatible strobe synchronization. The remote power supplies consist of a
filtered 24 VDC output that can be configured to drive four Style Y (Class B) NACs (Notification
Appliance Circuits). The four circuits can be configured for Style Z (Class A) with the optional
ZNAC-4 Class A converter module. Alternatively, th e four output circuits may be configured as 24
VDC resettable or nonresettable power outputs. The input circuits, which control the power supply
operation, are triggered by the reverse polarity of an NAC or by a 12 VDC or 24 VDC power
source. The power supplies are compatible with 12 VDC and 24 VDC control panels.
The FCPS-24FS6E and FCPS-24FS8E offer the same features as the FCPS-24FS6 and
FCPS-24FS8 respectively but allow connection to 220/240 VAC. Unless otherwise specified, the
information in this manual applies to both the 110/120 VAC versions and the 220/240 VAC
versions of the power supplies.
The FCPS-24FS6C and FCSP-24FS8C are the Canadian versions which offer the same features as
the FCPS-24FS6 and FCPS-24FS8 respectively. Unless otherwise specified, the information in this
manual also applies to the Canadian versions of the power supplies.
1.1 General
The FCPS-24FS power supplies can be used as remotely mounted power supplies and battery
chargers to power four noncoded or coded NACs. The Main FACP (Fire Alarm Control Panel)
NAC(s) is connected to the remote power supply input circuit(s). When the control input circuit
activates due to reverse polarity of the NAC from the FACP, the power supply will activate its
Notification Appliance Circuits.
During the inactive or nonalarm state, the power supply supervises its NAC field wiring for short
and open conditions. AC fail, battery, charger and ground fault troubles will also be monitored by
the power supply. If an NAC or power supply fault is detected, the power supply Normally-Closed
Trouble contact will open.
If an alarm condition occurs and the NAC is activated, the supervision is disabled and the
Notification Appliance Circuit is no longer supervised (except for shorts). Supervision of other
power supply faults such as low battery, AC loss, ground fault and battery charger trouble will
continue and may be monitored via the Trouble relay contacts.

CAUTION! Remove all power (AC & DC) before cutting or moving any jumpers.
1.4.1 Jumper JP1 - Ground Fault Detection
The Ground Detection circuit monitors for zero impedance between the power supply and ground.
Jumper JP1 is located in the top right section of the power supply circuit board. Cutting JP1 will
disable ground fault detection by the power supply. This should only be done if ground faults are
being monitored by a panel connected to the FCPS power supply.
1.4.2 Jumpers JP2 and JP3:
Coded/Noncoded Input Selection
Jumpers JP2 and JP3 are located in the top right section of the power supply circuit board. JP2 is
used for Control Input Circuit #1 and JP3 is used for Control Input Circuit #2. The position of
these jumpers will depend on the type of signal being fed to the input circuits:
• If the source voltage to the input circuit is a noncoded (steady voltage) input signal, the
24s8jp3b.cdr
jumper for the corresponding input circuit should be in the default position which jum pers
the bottom two pins (as illustrated in drawing at left).
• If the source voltage to the input circuit is coded (variable voltage), the jumper for the
corresponding input circuit should be moved to jumper the top two pins.
1.5 LED Indicators
• AC Power on (green) LED - indicates AC power is present
• Ground Fault (yellow) LED - indicates a ground fault condition (zero impedance to ground)
• Battery Trouble (yellow) LED - indicates low or no battery
• NAC Trouble (yellow) LED - indicates a Notification Appliance Circuit trouble (blinks once
for Circuit 1 trouble, twice for Circuit 2 trouble, three times for Circuit 3 trouble and four
times for Circuit 4 trouble. Note that multiple circuits in trouble will cause the LED to blink
the number of the circuit with the highest number)
• ChargerTrouble/AC Loss (yellow) LED - indicates a charger fault or loss of AC power:
If AC is applied to the power supply without a battery connected, both the Charger
Trouble/AC Loss LED and Battery Trouble LED will turn on simultaneously, indicating
that a battery is not connected.
When a battery is connected and the power supply is in Normal Mode, if the battery
voltage drops too low or the battery is disconnected, only the Battery Trouble LED will
turn on.
When a battery is connected and the charger develops a problem, only the Charger
Trouble/AC Loss LED will turn on.

1.7 General
System Overview
The FCPS may be used in a number of different applications. It may be used as a remotelymounted power supply and battery charger where it can provide up to four coded or noncoded,
synchronized or nonsynchronized NACs (Notification Appliance Circuits). Alternatively, output
#4 can be used as a door holder circuit which will provide a steady 24 VDC output until an alarm
condition or AC fail condition causes it to drop to 0 VDC following a 10 second delay. All four
outputs can also provide power.

One possible application for the FCPS remote power supply utilizes the NAC repeater feature. In
this application, one or two NACs are connected from the main FACP to the remote power supply
control input circuits. When the control input circuits are activated by the reverse polarity of the
NACs, the power supply will activate its corresponding output circuits as programmed by SW1
DIP switch configuration (refer to Table 3.1 on page 18).
During the inactive state, the remote power supply supervises its NAC field wiring for short and
open conditions. If a fault is detected, the power supply will enter a trouble condition and
illuminate the NAC Trouble LED. When the NACs are activated, the supervision is disabled and
the circuits are no longer supervised (except for short circuit conditions). Supervision of other
power supply faults such as low battery, battery charger trouble, ground fault and AC loss will
continue and may be monitored via the power supply trouble relay.
If an application requires that all four outputs activate at the same time, only one NAC is required
from the FACP. For this application, the NAC is connected to control input circuit #1 and SW1
DIP switch is set for this operation.

Installation
SECTION 2 Installation
Carefully unpack the system and check for shipping damage. Select a location for the cabinet that
is in a clean, dry, vibration-free area where extreme temperatures are not encountered. The area
should be readily accessible with sufficient room to easily install and maintain the power supply.
Locate the top of the cabinet approximately five feet above the floor with the hinge mounting on
the left. Determine the number of conductors required for the devices to be installed and determine
the appropriate knockouts. All wiring must be in accordance with the National and/or Local codes
for fire alarm systems and power supplies.
2.1 Backbox Mounting
The circuit board contains static-sensitive components. Always ground yourself with a pr oper wrist
strap before handling any boards so that static charges are removed from the body. Use static
!
suppressive packaging to protect electronic assemblies.
1. Remove the PC board and transformers from the backbox before installing backbox. Set the
board and transformers aside in a safe, clean place. Avoid static discharge which may
damage static sensitive components on the board
2. Mark and predrill holes for the top two keyhole mounting bolts
3. Install two upper fasteners in the wall with the screw heads protruding approximately ¼”
4. Using the upper keyholes, mount the backbox over the two screws
5. Mark the lower two holes, remove the backbox from the wall and drill the mounting holes
6. Mount the backbox, install the remaining fasteners and tighten all screws
7. When the location is dry and free of construction dust, reinstall the PC board and
transformers and continue with the installation
8. IMPORTANT! Make certain to connect the supplied grounding strap between the Earth
terminal on TB1 (AC Terminal Block) of the main circuit board and the chassis ground stud
as illustrated in Figure 2.1:
