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 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 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,
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
2
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

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 . 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 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 Circuits). 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 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:
DISCONNECT POWER
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 HPF24S power supply.
1.4.2 Jumpers JP2 and JP3: Coded/Noncoded Input Selection
•
•
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.

Figure 1.2 Simplified HPF24S Block Diagram
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 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 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 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.

2.3 Addressable Module Mounting
The HPF24S has been designed to allow the mounting of an addressable control, relay or monitor
module on the main circuit board inside the power supply cabinet with the module status LED visible through the closed door. This allows power to be fed from the HPF24S Auxiliary Power output
directly to the module, if needed, without running the power wires outside the cabinet. As an example, Figure 2.5 illustrates wiring from the Auxiliary power output terminals to a CMF-300 control
module’s terminals 3 (-) and 4 (+).
NOTE: The optional module mounting kit (P/N 90286) is required to install an addressable
module on the power supply main circuit board. The kit includes four female/female and four
male/female standoffs as well as four mounting screws.

3.2 Programmable Features Description
3.2.1 Synchronization Type Selection
Synchronization is a feature that controls the activation of notification appliances in such a way that
all devices will turn on and off at exactly the same time. This is particularly critical when activating strobes which must be synchronized to avoid random activation and a potential hazard or confusion. The HPF24S can be programmed to operate with a variety of manufacturer’s devices. Note
that strobe synchronization works only with non-coded NACs.
DIP switches 1 and 2 are used to select the type of synchronization as listed below:

Table 3.2 Sync Type Settings
Maximum Number of Strobes for Synchronization
The total current draw for each Notification Appliance Circuit cannot exceed 3.0 amps, special
application, 300mA regulated. Refer to the manufacturer’s documentation supplied with the strobes
to determine the maximum current draw for each strobe and ensure that the circuit maximum is not
exceeded.
To ensure proper strobe and circuit operation, there is also a limit to the number of strobes that can
be attached to each circuit. Following is a table of the strobes that have been tested with the power
supply and the maximum number that can be connected to each NAC when using the lowest candela settings. Make sure that the NAC maximum current is not exceeded:

3.2.2 Synchronization Mode - Master/Slave
The HPF24S power supply can be configured for Master or Slave Synchronization by setting DIP
switch 3 ON for Slave or OFF for Master mode.
In some installations, it is necessary to synchronize the flash timing of all strobes in the system for
ADA compliance. Strobes accomplish this by monitoring very short timing pulses on the NAC
power which are created by an FACP with synchronization capability. When installed at the end of
a NAC wire run, this power supply can track (that is follow) the strobe synchronization timing
pulses on the existing NAC wire run. This maintains the overall system flash timing of the additional strobes attached to this power supply.
When this power supply is configured as a sync generator (Master Synchronization mode), the
Sync Input terminals are not used. The power supply is the originator of the strobe synchronization
pulses on its NAC outputs. In sync generator mode, the sync type (System Sensor, Wheelock, or
Gentex) is selectable via DIP switches 1 and 2.
When this power supply is configured as a sync follower (Slave Synchronization mode), the power
supply’s NAC outputs track the strobe synchronization pulses present at the supply’s Sync Input
terminals. The pulses originate from an upstream FACP or other power supply. Some FACPs pro-
HPF24S Series Power Supplies — P/N 52751:F1 10/15/13
21
Programming Options
Programmable Features Description
vide synchronization timing pulses from a dedicated sync output connector. Connect the HPF24S
sync input terminals to the FACP sync output connector instead of the FACP NAC.
Note that the Synchronization Type configured by DIP switches 1 and 2 must be set to the same type
as the signal being fed to the Sync Input circuit in the event that Selective Silence is employed.
Important! In Slave Mode, if the Input is active, but no signal is present on the Sync Input circuit,
the power supply will turn the NACs on steady until a sync signal appears. The NACs will turn off
when the Input becomes inactive.
Also in Slave Mode, if the Input is active and the Sync Input is suddenly lost (HPF24S or wiring
failure), there will be a three second period when NAC outputs are indeterminate. After this three
second period, the power supply will turn the NACs on steady until the Input becomes inactive.
3.2.3 AC Fail Delay/Aux. Trouble Relay Function
The AC Fail Delay feature provides the option to delay generation of a trouble signal upon the loss
of AC power. In addition, the operation of the Aux. Trouble Relay is altered.
•
DIP switch 4 set to the ON position will delay the generation of an AC Loss/brownout trouble
signal for 2 hours. In addition, the Aux. Trouble Relay will immediately respond to all trouble
conditions on the power supply.
•
DIP switch 4 set to the OFF position will allow the HPF24S to generate a trouble signal
immediately on the loss of AC power. In addition, the Aux. Trouble Relay will respond only
to AC power fail/brownout conditions.
Refer to “Supervision of HPF24S Faults” on page 25, for operation of internal NAC trouble relay
in response to AC loss.
3.2.4 Input/Output Function
DIP switches 5 and 6 are used to determine the Input Control circuits that will activate the four output circuits and the function of the output circuits. For example, to configure a General Alarm
operation in which Input Control Circuit #1 activates all four output NACs, DIP switches 5 and 6
are both set to the OFF position. In this configuration, the Sync Input circuit is ignored if the power
supply is set as a Master but will be monitored if the supply is set as a Slave. In addition, if the
Auxiliary Power output is set as a resettable output, the circuit connected to Control Input Circuit
#2 will control the auxiliary power reset function.
The following table details the four possible input/output configurations:

2 If no synchronization is selected by switches 1 & 2, the Sync Input is ignored.
3 When using Split Alarm with power supply configured for Slave Mode, System Sensor cannot be used (use
System Sensor with Master Mode only).
4 Selective Silence allows the silencing of the sounder portion of a horn/strobe combination device without turning
off the strobe.
Auxiliary Power Control
The 24 VDC Auxiliary power from TB4 Terminals 9(+) & 10(-) can be resettable or nonresettable
power only when the power supply is configured for General Alarm operation. For all other configurations, the auxiliary power output is only nonresettable.
In the General Alarm configuration, the Auxiliary power output can be made resettable by applying
a steady signal to Control Input 2 (positive 12 to 24 VDC on TB4 Terminal 7 and common on Terminal 8). Temporarily removing the voltage or reversing the polarity will cause the Auxiliary
power output to reset for 6 seconds.
3.2.5 Charger Enable/Disable
The HPF24S battery charger can be disabled to accommodate an external battery charger. Setting
DIP switch 7 to the default setting of OFF will enable the battery charger. Setting DIP switch 7 to
the ON position will disable the charger. It should only be disabled if an external battery charger is
being used for the HPF24S.
3.2.6 Door Closers
Output Circuit #4 can be configured as an NAC or door closer circuit. Setting DIP switch 8 to the
OFF position will configure Output Circuit #4 as an NAC. Setting DIP switch 8 to the ON position
will configure only Output Circuit #4 as a door closer circuit which will provide a steady 24 VDC
to door holders until an alarm or AC fail condition removes the power following a 10 second delay.

Section 4: Trouble Supervision
4.1 Supervision via FACP Notification Appliance Circuit
4.1.1 Supervision of FACP to HPF24S wiring
The FACP (Fire Alarm Control Panel) supervises the connection between itself and the HPF24S
via the control panels NAC End-of-Line Resistor (ELR). The ELR must be installed at the FCPS
end of the circuit, after the last notification appliance on the circuit. If no additional devices are
connected from the HPF24S Control Input terminals, the ELR must be connected across terminals
5 & 6 for Control Input Circuit #1 and across terminals 7 & 8 for Control Input Circuit #2. An open
or short anywhere on the control panel’s NAC or power supply NAC will be detected at the FACP
as a NAC trouble.
IMPORTANT: If additional notification appliances are connected to the Out terminals 5 & 6 of
Control Input Circuit #1 or extended from Control Input Circuit #2 Terminals 7 & 8, the ELR must
be installed after the last device on the circuit.
4.1.2 Supervision of HPF24S Faults
The FACP will detect HPF24S power supply faults as an open circuit condition on its NAC. An
internal trouble contact is located between TB4 Terminal 3 (In+) and TB4 Terminal 5 (Out+). Any
of the following conditions will cause the trouble contact to open, provided the FACP Notification
Appliance Circuit is not in alarm. The following trouble conditions will cause a general NAC trouble:
•
A field wiring fault on the NAC output of the power supply
•
An AC fail condition at the power supply (only if SW1 switch 4 is ON and a 2 hour delay has
expired. If SW1 switch 4 is OFF, the Internal Trouble contact will not respond to an AC fail
condition)
•
A battery fail condition at the power supply
•
A battery charger fail on the power supply
•
A ground fault condition on the power supply (zero impedance between power supply and
ground)
Any power supply trouble will break the connection between the FACP and the ELR connected to
Control Input #1 provided the FACP’s NAC is not in alarm. The FACP’s ELR must be placed after
the last notification appliance connected to FCPS terminals 5 & 6 on TB4 or, if no devices are connected to these terminals, the ELR must be connected directly across terminals 5 & 6.
If trouble monitoring is required when the power supply is in alarm, the Trouble Relay at TB5 can
be used for this purpose. An addressable monitor module may be used to monitor these contacts.
Refer to “Aux. Trouble Relay/AC Fail Relay” on page 25 in the following section.
NOTE: Control Input #2 (terminals 7 & 8) cannot be used to supervise the power supply for
internal troubles, but an ELR is still required for FACP wiring supervision.
4.1.3 Aux. Trouble Relay/AC Fail Relay
The HPF24S power supply has one fail-safe Form-C aux. trouble relay located at TB5. The contacts can be monitored by an FACP input circuit or an addressable monitor module as illustrated
below. The Aux. Trouble Relay responds to HPF24S power supply troubles depending on the setting of SW1 switch 4.

Trouble Supervision
AC Loss Reporting Delay
•
With SW1 switch 4 set to the ON position, AC Fail/brownout reporting will be delayed 2 hours
and the following trouble conditions will cause the normally energized Aux. Trouble Relay to
change states regardless of whether the panel is in alarm or standby:
– An AC fail condition at the power supply
– A battery fail condition at the power supply
– A battery charger fail on the power supply
– A ground fault condition on the power supply (zero impedance between the power supply
and ground
– A field wiring fault on the NAC output of the power supply. (If the panel is in alarm, only a
short circuit on the NAC will be detected as a trouble)
NOTE: The NAC Trouble LED will indicate which NAC circuit is in trouble by blinking once for
Circuit 1, twice for Circuit 2, three times for Circuit 3 and four times for Circuit 4. If more than one
circuit is in trouble, the LED will blink the highest circuit number in trouble.
•
With SW1 switch 4 set to the OFF position, AC Fail/brownout reporting will occur
immediately and the Aux. Trouble Relay will change state only for AC Fail/brownout
conditions. A monitor module can be used to monitor the relay for AC fail.

The reporting of AC loss to a central station is usually delayed in order to prevent multiple transmissions of AC loss and restoral, thus allowing AC power to stabilize. When a host FACP is programmed to delay AC loss reporting, the HPF24S must be configured to delay the reporting of AC
fail. This is accomplished by setting SW1 DIP switch 4 to the ON position. This will prevent AC
loss from being reported as a trouble condition for two hours.
Changing the AC Loss Reporting setting will also affect the functioning of the Trouble Relay.
Refer to “Aux. Trouble Relay/AC Fail Relay” on page 25.
Note that the HPF24S power supply will immediately indicate loss of AC power by turning off the
AC Power LED and turning on the Charger Trouble/AC Loss LED, regardless of the setting of
SW1 DIP switch 4.

5.1 Controlling Four NACs With One Input and Selective
Silence
NOTE: The Relay Module is required only for this application with the power supply set as Master.
If the power supply is set as Slave, the Relay Module is not required. In Slave mode, selective
silence (horn mute) is provided by the FACP through the sync input.
In this application, the power supply has been set as a master with synchronized outputs and selective silence (see SW1 switch settings in following illustration). All four HPF24S output circuits,
which are shown as NACs (Notification Appliance Circuits), can be controlled from one input such
as an addressable control module as illustrated in Figure 5.1. The control module can be powered
from the HPF24S auxiliary 24 VDC power output (TB4, Terminals 9 & 10) and supervised by an
EOL relay. An addressable relay module, programmed as an alarm output and a silenceable point,
can be used as a selective silence input.
NOTE: Mass Notification (MN) only, Fire only, or MN/Fire combo NACs only are
allowed.

5.4 Remote Supply With Resettable and Nonresettable Power
The HPF24S can be used as a remote stand-alone power supply to provide power to any devices
that require filtered, resettable or nonresettable power. The HPF24S6 can provide up to 4 amps of
continuous current and the HPF24S8 can provide up to 6 amps of continuous current. The power
supply must be set for Split Alarm mode. Output circuits 1 & 2 are configured as resettable power
outputs by connecting the resettable power from an FACP to Control Input 1 Terminals 3(+) & 4(-)
on TB4 of the HPF24S. Output circuits 3 & 4 are configured as nonresettable power outputs by
connecting jumpers between the auxiliary 24 VDC output on TB4 to the Control Input 2 terminals
on TB4 [Terminals 9(+) to 7(+) and 10(-) to 8(-)].
NOTE: All four outputs can be configured as resettable or all four can be configured as
nonresettable by setting the power supply for General Alarm and then connecting a resettable
power source to Control Input 1 or a nonresettable power source, such as the Aux. Power output
of the HPF24S, to Control Input 1.

Section 6: Power Supply Requirements
6.1 Overview
This section contains instructions and tables for calculating power supply currents in alarm and
standby conditions. This is a four-step process, consisting of the following:
1.
Calculating the total amount of AC branch circuit current required to operate the system
2.
Calculating the power supply load current for non-fire and fire alarm conditions and
calculating the secondary (battery) load
3.
Calculating the size of batteries required to support the system if an AC power loss occurs
4.
Selecting the proper batteries for your system
6.2 Calculating the AC Branch Circuit
The power supply requires connection to a separate, dedicated AC branch circuit, which must be
labeled FIRE ALARM. This branch circuit must connect to the line side of the main power feed
of the protected premises. No other non-fire alarm equipment may be powered from the fire alarm
branch circuit. The branch circuit wire must run continuously, without any disconnect devices,
from the power source to the power supply. Overcurrent protection for this circuit must comply
with Article 760 of the National Electrical Codes as well as local codes. Use 14 AWG (2.00 mm2)
wire with 600 volt insulation for this branch circuit.
Use Table 6.1 to determine the total amount of current, in AC amperes, that must be supplied to the
system.

6.3 Calculating the System Current Draw
6.3.1 Overview
The power supply must be able to power all internal and external devices continuously during the
non-fire alarm condition. To calculate the non-fire alarm load on the power supply when primary
power is applied, use Calculation Column 1 in Table 6.3 on page 40. The power supply must support a larger load current during a fire alarm condition. To calculate the fire alarm load on the
power supply, use Calculation Column 2 in Table 6.3 on page 40. The secondary power source
(batteries) must be able to power the system during a primary power loss. To calculate the non-fire
alarm load on the secondary power source, use Calculation Column 3 in Table 6.3 on page 40.
When calculating current draw and the battery size, note the following:
•
Primary refers to the main power source for the power supply.
•
Secondary refers to the power supply’s backup batteries.
•
All currents are given in amperes (A). Table 6.2 shows how to convert milliamperes and
microamperes to full amperes.
To convert...
Multiply
Milliamperes (mA) to
amperes (A)
mA x 0.001
Microamperes (μA) to
amperes (A)
μA x 0.000001
Example
3 mA x 0.001 = 0.003 A
300 μA x 0.000001 = 0.0003 A
Table 6.2 Converting to Full Amperes
6.3.2 How to Calculate System Current Draw
Use Table 6.3 on page 40 to calculate current draws as follows:
1.
Enter the quantity of devices in all three columns.
2.
Enter the current draw where required. Refer to the HPP Device Compatibility Document for
compatible devices and their current draws.
3.
Calculate the current draws for each in all columns.
4.
Sum the total current for each column.
5.
Copy the totals from Column 2 and Column 3 to Table 6.3 on page 40.
Following are the types of current that can be entered into Table 6.3 on page 40.
 Calculation Column 1 - The primary supply current load that the power supply must
support during a non-fire alarm condition, with AC power applied
 Calculation Column 2 - The primary supply current load the power supply must support
during a fire alarm condition, with AC power applied
 Calculation Column 3 - The standby current drawn from the batteries in a non-fire alarm
condition during a loss of AC power

Use Table 6.4 to calculate the total Standby and Alarm load in ampere hours (AH). This total load
determines the battery size (in AH) required to support the power supply under the loss of AC
power. Complete Table 6.4 as follows:
1.
Enter the totals from Table 6.3 on page 40, Calculation Columns 2 and 3 where shown.
2.
Enter the NFPA Standby and Alarm times. Refer to Section 6.4.1, “NFPA Battery
Requirements”.
3.
Calculate the ampere hours for Standby and Alarm, then sum the Standby and Alarm ampere
hours.
4.
Multiply the sum by the derating factor of 1.2 to calculate the proper battery size (in AH).
5.
Write the ampere hour requirements on the Protected Premises label located inside the cabinet
door.

6.4.1 NFPA Battery Requirements
NFPA 72 Local and Proprietary Fire Alarm Systems require 24 hours of standby power followed by
5 minutes in alarm.
6.4.2 Selecting and Locating Batteries
Select batteries that meet or exceed the total ampere hours calculated in Table 6.4. The power supply can charge batteries in the 7 AH to 18 AH range. The power supply cabinet is capable of housing batteries up to 7 AH. Batteries larger than 7 AH require the BB-17F or other UL listed external
battery cabinet.

Appendix A: Wire Requirements
Connecting external system accessories to the main circuits must be carefully considered to ensure
proper operation. It is important to use the correct type of wire, gauge and run length for each circuit. The following table lists NAC wiring requirements for the HPF24S6 and HPF24S8 Field
Charger Power Supply.

Table A.1 NAC Wiring Requirements for Power Supply
NOTE: Calculations are based on Direct-Current Resistance data for uncoated copper wire, per
National Electrical Code (2005 Edition) Table 8, Conductor Properties.
NOTE: These distances reflect the worst case scenario and are based on the correct draw of the
highest candela strobes at the low end of the supported NAC voltage with the entire load at the
end of the circuit. Further distances can be achieved by performing a point to point voltage
calculation that more accurately reflects the specific devices used and how they are dispersed on
the circuit.
