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 develop-

ing 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 detec-

tors 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.systemsen-

sor.com/html/applicat.html. A study by the Federal Emer-

gency 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 sys-

tem 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 ion-

izing-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 predeter-

mined 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 pro-

tection 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 sys-

tem for the connection of alarm transmission wiring, communi-

cations, signaling, and/or power. If detectors are not so

located, a developing fire may damage the alarm system, crip-

pling 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 medica-

tion. 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 responsi-

bility 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 com-

patible with the control panel. It is essential to use only equip-

ment 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 tele-

phone line failure, backup radio transmission systems are rec-

ommended.

The most common cause of fire alarm malfunction is inade-

quate 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 stan-

dards. 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 main-

tenance agreement should be arranged through the local man-

ufacturer'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 associ-

ated equipment may be damaged by removing and/or insert-

ing 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 pro-

gramming 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 compo-

nents, 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 (non-

condensing) at 32°C ± 2°C (90°F ± 3°F). However, the useful

life of the system's standby batteries and the electronic com-

ponents 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 indi-

cating 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 light-

ning 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 Ser-

vices Department if any problems are anticipated or encoun-

tered.

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 modifi-

cations, verify that they will not interfere with battery, trans-

former, 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 han-

dling 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 pro-

gramming 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 HPF24S6 is a 6 amp power supply and the HPF24S8 is an 8 amp power supply. Each HPF24S

power supply is a compact, cost-effective, remote power supply and battery charger which provides

ADA compatible strobe synchronization. Each remote power supply consists of a filtered 24 VDC

output that can be configured to drive four Style Y (Class B) NACs (Notification Appliance Cir-

cuits). The four circuits can be configured for Style Z (Class A) with the optional ZNAC-4 Class A

converter module. Alternatively, the 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 HPF24S6E and HPF24S8E offer the same features as the HPF24S6 and HPF24S8 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 HPF24S6C and HPF24S8C are the Canadian versions which offer the same features as the

HPF24S6 and HPF24S8 respectively. Unless otherwise specified, the information in this manual

also applies to the Canadian versions of the power supplies.

1.1 General

The HPF24S 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 Notifica-

tion Appliance Circuit is no longer supervised (except for shorts). Supervision of other power sup-

ply faults such as low battery, AC loss, ground fault and battery charger trouble will continue and

may be monitored via the Trouble relay contacts.

4. Wire the power supply circuits, referring to the options described in“Trouble Supervision” on

page 25 and the application examples in“Applications” on page 27.

5. Connect primary power source wiring while observing the following:

– Make certain that the AC mains circuit breaker is off before making any wiring connections

between the mains and the power supply.

– Make certain primary power source is 120 VAC, 60 Hz, 3.2 amps.

– Run a pair of wires (with ground conductor) from the protected premises main breaker box

to TB1 of the power supply main circuit board.

– Use 14 AWG (1.6 mm O.D.) or heavier gauge wire with 600V insulation.

6. Apply power to the power supply using the following procedure:

– Apply AC power by turning on the AC mains circuit breaker connected to the power supply.

– Connect a properly charged battery to connector JP4 on the power supply main circuit

board.

1.4 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 HPF24S power supply.

CAUTION: DISCONNECT POWER

REMOVE ALL POWER (AC & DC) BEFORE CUTTING OR MOVING ANY JUMPERS.

System Overview LED Indicators

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 jump-

ers 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 jumper for the corresponding input

circuit should be in the default position which jumpers 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.

NOTE: Cutting Ground Fault jumper JP1 voids UL/NFPA Style/Class identifications for circuits

unless Ground Faults are being monitored by an FACP connected to the power supply. Cut

jumper JP1 only if a panel connected to the power supply is monitoring for Ground Faults or with

the approval of AHJ (Authority Having Jurisdiction).

General System Overview

1.7 General

The HPF24S may be used in a number of different applications. It may be used as a remotely-

mounted power supply and battery charger where it can provide up to four coded or noncoded, syn-

chronized 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 con-

dition or AC fail condition causes it to drop to 0 VDC following a 10 second delay. All four out-

puts can also provide power.

One possible application for the HPF24S 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 sup-

ply 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 20).

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 illumi-

nate the NAC Trouble LED. When the NACs are activated, the supervision is disabled and the cir-

cuits 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.

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

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:

CAUTION: STATIC SENSITIVE COMPONENTS

THE CIRCUIT BOARD CONTAINS STATIC-SENSITIVE COMPONENTS. ALWAYS GROUND

YOURSELF WITH A PROPER WRIST STRAP BEFORE HANDLING ANY BOARDS SO THAT

STATIC CHARGES ARE REMOVED FROM THE BODY. USE STATIC SUPPRESSIVE PACKAGING

TO PROTECT ELECTRONIC ASSEMBLIES.
