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 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, chimneys, even wet or humid areas may inhibit particle or sm
oke
flow.
•
Smoke particles may become “cold,” stratify, and not reach t
he
c
eiling 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 reachi
ng
t
he 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 rateof-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 Authoritie
s
Havi
ng 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 meani
ng
of
the signal. Audible devices, such as horns and bells, can hav
e
di
fferent tonal patterns and frequencies. It is the property
owner's responsibility to conduct fire drills and other traini
ng
ex
ercises to make people aware of fire alarm signals an
d
i
nstruct them on the proper reaction to alarm signals.
• In rare instances, the sounding of a warning device can ca
use
t
emporary 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,
backu
p 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 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. Re-acceptance 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 . 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. 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.

6 HPFF12 NAC Expander — P/N 53576:B3 10/1/2018
The Honeywell Power Products FireForce (HPFF) is one of the most innovative fire alarm remote power supplies available that complies with UL 864 9th Edition. Designed with advanced switch-mode power supply technology and built with the latest surface-mount
electronic manufacturing techniques, they incorporate several new features that demanding installers requested to speed them through
installation and servicing.
The HPFF12 is a 12.0 A power supply that provides power for Notification Appliance Circuit (NAC) expansion to support ADA requirements and strobe synchronization (sync). It provides filtered 24 VDC power to drive four NAC outputs. The four-output circuits may be
configured as: four Class B (Style Y); two Class A (Style Z); two Class B and one Class A; or four Class A with the optional HPP31076
Class A adapter installed. The input circuits, which control the power supply operation, are triggered by the reverse polarity of a NAC or
by the reverse polarity of a 12 VDC or 24 VDC power source. The power supply is compatible with 12 VDC or 24 VDC control panels.
It contains an internal battery charger capable of charging up to 26.0 AH (amp hour) batteries.
The HPFF12 is a wall cabinet unit that can accommodate up to two 18 AH batteries. It can be configured to internally house one addressable control or relay module, a six-circuit relay module, or a six-circuit control module. (Modules available through authorized Honey-
well Fire Systems distributors.)
HPFF12CM is a chassis-mount model that can fit two 12.0 AH batteries. It is used for a multi-pack option that allows up to three
HPFF12CM units to be mounted in a compatible Fire Alarm Control Panel (FACP) cabinet; these separately sold cabinets are also
referred to as the large equipment enclosure. The addressable control or relay module option is not available on these models. (Equip-
ment enclosures available through authorized Honeywell Fire Systems distributors.)
HPFF12 and HPFF12CM power supply models operate at 120 VAC/60 Hz.
HPFF12E and HPFF12CME power supply models are export units that operate at 240 VAC/50 Hz.
NOTE: When an HPFF12CM unit is mounted in a FACP cabinet, the top row must be left open for proper heat dissipation.
1.1 General
The HPFF power supplies are used as remotely mounted power supplies and battery chargers. The Fire Alarm Control Panel (FACP) or
initiating device is connected to the input circuit(s). When the control input circuit activates due to the reverse polarity of the signal from
the initiating device, the power supply will activate its NAC outputs.
During the inactive or non-alarm state, the power supply supervises its NAC field wiring independently for short and open conditions. If
a NAC fault is detected, the power supply will open the initiating device input signal to notify the FACP and the Normally-Closed Trouble contact. If an AC loss is detected, the power supply will open the initiating device input signal, Normally-Closed Trouble, and a dedicated AC Fail contact.
If an alarm condition occurs and the NAC outputs are activated, the supervision and charger are disabled and the NAC circuit is no longer supervised (except for excessive loading or shorts). Supervision of other power supply faults such as battery voltage, AC loss, and
ground fault will continue and may be monitored via Trouble contacts.

1.4.1 Charger Disable Jumper (J1)
The HPFF power supplies’ battery charger capacity is 26 AH maximum using the integral
charger with a maximum charging rate of 0.75 A. The integral charger on the Control circuit
board must be disabled in certain situations by removing the charger-disable jumper. One
situation is when system requires a common battery set, as is possible in the large equipment
enclosure. Another situation is if the system requires a larger battery capacity than the integral charger can charge in the proper time. Larger capacity batteries can be used if they are
housed in an external UL-Listed enclosure, along with a UL-Listed battery charger that can
restore the full charge to the batteries in the proper time.
CAUTION: BATTERY CHARGER DISABLE
THE BATTERY CHARGER IS AUTOMATICALLY DISABLED DURING ALARM, SO BATTERIES WILL NOT BE
CHARGED WHEN THE POWER SUPPLY IS IN THE ALARM STAGE.
Larger capacity batteries can be used if they are housed in an external UL-Listed enclosure, along with a UL-Listed battery charger suitable for fire alarm service and with sufficient capacity to restore the full charge in the required time. The alternate enclosure and battery
charger shall be listed for Fire Protective Signaling use.
1.4.2 Ground Fault Disable Jumper (J2)
The Ground Fault detection circuit on the Control circuit board monitors the impedance
from earth ground to any user wiring point, including +24 VDC. An exception is the
initiating device signal inputs because they are optically-isolated from the rest of the
circuitry and should be detected by the initiating device or FACP. Remove ground-fault
disable jumper to disable the ground fault detection.
If the common circuitry of two or more HPFFs are connected together, or if the common of an HPFF is connected to the common of a system, such as a single battery connected to multiple units, then the ground fault jumpers must be removed from all but
one of the units. The unit with the jumper installed provides the ground monitoring for
the whole system. If two or more units are connected together with ground fault monitoring enabled, then the monitoring circuits interfere with each other, and false ground faults will be generated.

Each cabinet mounts using two or three key slots and two 0.250" (6.35 mm) diameter holes in the backbox. The key slots are located at
the top of the backbox and the two securing holes at the bottom.
Carefully unpack the system and check for shipping damage. Mount the cabinet 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 panel. Locate
the top of the cabinet approximately 5 feet (1.5 m) above the floor with hinge mounting on the left. Determine the number of conductors
required for the devices to be installed. Sufficient knockouts are provided for wiring convenience. Select the appropriate knockout(s) and
pull the conductors into the box. All wiring should be in accordance with the National and/or Local codes for fire alarm systems and
power supplies.
2.1 Backbox Mounting
CAUTION: STATIC SENSITIVE COMPONENTS
THE CIRCUIT BOARD CONTAINS STATIC-SENSITIVE COMPONENTS. ALWAYS GROUND YOURSELF WITH A STATIC
STRAP BEFORE HANDLING ANY BOARDS SO THAT THE STATIC CHARGES ARE REMOVED FROM THE BODY. USE
STATIC SUPPRESSIVE PACKAGING TO PROTECT ELECTRONIC ASSEMBLIES.
To prevent damage to the circuit board and to facilitate backbox mounting, the chassis with the 24 VDC power supply and the Control
circuit board can be easily removed. Loosen the two #8-32 nuts securing the top flanges of the chassis, then slide the chassis up to free it
from the lower tabs. Place the chassis assembly in a safe location until it can be reinstalled in the backbox.
1. Mark and pre-drill a hole in the wall for the center top keyhole mounting bolt using the dimensions illustrated in Figure 2.2 or
Figure 2.3.
NOTE: See the EQ Series Install Sheet PN 53412 for door-mounting details and measurements for B-size and C-size backboxes.
2. Install the center top fastener in the wall with screw head protruding.
3. Place backbox over the top screw, level and secure.
4. Mark and drill the left and right upper and lower mounting holes.
Note: outer holes (closest to sidewall) are used for 16" O.C. stud mounting.
5. Install remaining fasteners.
