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.

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.

Section 1: System Overview

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.

1.2 Features

1.7 General

The HPF24S may be used in a number of different applications. It may be used as a remotelymounted power supply and battery charger where it can provide up to four coded or noncoded, synchronized or nonsynchronized NACs (Notification Appliance Circuits). Alternatively, output #4 can be used as a door holder circuit which will provide a steady 24 VDC output until an alarm condition or AC fail condition causes it to drop to 0 VDC following a 10 second delay. All four outputs can also provide power.

One possible application for the 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.

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.

2.3 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.

Programmable Features Description Programming Options

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:

DIP Switch 1 DIP Switch 2 Synchronization Type

OFF OFF no synchronization (steady 24V)

OFF ON System Sensor

ON OFF Gentex

ON ON Wheelock

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. 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:

Strobe Manufacturer HPF24S6 (max. strobes) HPF24S8 (max. strobes)

System Sensor 51 51

Wheelock 30 40

Gentex 39 39

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 provide synchronization timing pulses from a dedicated sync output connector. Connect the HPF24S

HPF24S Series Power Supplies — P/N 52751:E1 4/14/2011 21

Programming Options Programmable Features Description

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:

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.

*If the SLC device does not match the one in this figure, refer to the SLC manual wiring conversion charts for legacy and newer versions of the modules.

• 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.

4.2 AC Loss Reporting Delay

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.

Section 5: Applications

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.

The control module is shown to demonstrate the use of a remotely mounted device associated with an addressable fire alarm control panel. The module could be replaced with any circuit capable of polarity reversal, such as an FACP NAC.

The following notes apply to Figure 5.1 on page 28.

1. When the HPF-24S power supply is in an inactive state (control module not active), a trouble on the power supply will result in an open circuit condition on the control module output circuit (monitored by End-of-Line Resistor across TB4, Terminals 5 & 6). As an alternative, the trouble contacts at TB5 of the power supply can also be used for independent trouble monitoring.

2. The addressable relay module must be programmed as a silenceable point at the FACP to allow selective silence of horn/strobe devices. The Normally Open contact of the relay module is connected between TB4 Terminal 7 (IN2 +) and Terminal 9 (Aux. Power +).

3. Do not loop wires under screw terminals. Break wires to maintain proper supervision.

4. An End-of-Line Resistor must be installed between TB4, Terminals 5 & 6 for control module wiring supervision (the ELR value is dependent on the module employed).

7. IMPORTANT! When the power supply is programmed for both Selective Silence and Slave Mode, TB4 Terminal 7 (IN+) must be jumpered to Terminal 9 (AUX+) and Terminal 8 (IN-) must be jumpered to Terminal 10 (AUX-). The FACP will control the Selective Silence feature with this configuration. If the terminals are not jumpered as indicated, the horn portion of the horn/strobes will be silenced

at all times.

The following notes apply to Figure 5.3 on page 32.

1. When the HPF24S power supply is in an inactive state (control module not active), a trouble on the power supply will result in an open circuit condition on the control module output circuit (monitored by an End-of-Line Resistor across Terminals 5 & 6). As an alternative, the trouble contacts at TB5 of the power supply can also be used for independent trouble monitoring.

2. Do not loop wires under screw terminals. Break wires to maintain proper supervision.

3. An End-of-Line Resistor must be installed between terminals 5 & 6 for control module wiring supervision (the ELR value is dependent on the module employed) and across terminals 7 & 8 for FACP NAC wiring supervision (the ELR value is dependent on the NAC).

4. For a list of compatible devices, refer to .

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 mm 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 Example

Milliamperes (mA) to amperes (A)

Microamperes (A) to amperes (A)

mA x 0.001 3 mA x 0.001 = 0.003 A

A x 0.000001 300 A 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
