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 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 first­floor 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 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, 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 panel. 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 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.

Section 1: System Overview

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 switch­mode 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 Honeywell 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.
(Equipment 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.

System Overview Jumpers

!

1.4 Jumpers

The HPFF power supplies are comprised internally of two basic components: a 24 VDC power
supply and a Control circuit board. The HPFF12 models have an installed 12.0 A power supply.
Jumpers are located on the control circuit board; see Figure 1.1, “Control Circuit Board”.

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:

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.

Section 2: Installation

!

The standard cabinet may be either semi-flush or surface mounted. Fire Alarm Control Panel
(FACP) cabinets can only be wall mounted. 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: 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 predrill a hole in the wall for the center top keyhole mounting bolt using the

dimensions illustrated in Figure 2.2, “Standard Cabinet: Dimensions for Wall-mounting”
on page 19 or Figure 2.3, “FACP Cabinet-Mounting Details: Backbox-Mounting Holes
and Chassis-Mounting Studs (EQBB-D4 shown)” on page 20.

NOTE: See 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.

5. Note: outer holes (closest to sidewall) are used for 16" O.C. stud mounting.

6. Install remaining fasteners.
