3. Connect the 14 Conductor Cable from the power supply to the Main Back Board.

Installing Power Supplies

FireNET L@titude Fire Alarm Control Panels can be equipped with either a 5.25 Amp or 10.25 Amp power
supply. Set DIP switches on the 5.25 Amp and 10.25 Amp Power Supplies before completing the installation
process. Refer to DIP Switch Settings. The power supply settings must be performed to establish the optimal
charge current of the standby batteries. These power supplies can be set to operate at inputs of 115 VAC or 230
VAC. For more information about the power supplies and their functions, see Power Supplies.

The 5.25 Amp Power Supply

The 5.25 Amp Power Supply contains a jumper setting for changing from 115 VAC to 230 VAC. Check the
jumper setting prior to wiring and operating the 5.25 Amp Power Supply with the FireNET L@titude Fire Alarm
Control Panel.

Hochiki America Corporation

FireNET L@titude Fire Alarm Control Panel Installation
Page 24
Manual
Installation

Confirm that the 5.25 Amp Power Supply is set for 230 VAC before operating at 230 VAC. Permanent damage
of the power supply will result if the 115 VAC jumper setting exists while operating the power supply at 230 VAC.

WARNING! Remove jumper J1 before operating the FireNET L@titude Fire Alarm Control Panel at 230 VAC.
Failure to remove jumper J1 prior to operating at 230 VAC will cause permanent damage to the 5.25 Amp power
supply.

High voltage present on jumper pins. Remove AC power before changing jumper setting.

Voltage Jumper Required

115 Yes
230 No

Refer to Connecting Field Wiring for specific details about wiring the power supplies. Provide an AC power
connection to the terminal block from a 15 Amp branch circuit. The following figure illustrates AC connections of
the 5.25 Amp Power Supply:

Hochiki America Corporation

Version 3.01 | June 2023 | MAN-1431HA

 Installation

1. Connect a wire from the ground terminal ( ) to the grounding block of the cabinet box.

2. Connect a wire from the grounding block of the cabinet box to a ground. Provide this connection in close proximity to
the cabinet box.
3. Connect a wire from the neutral terminal (N) to the neutral of the power source.
4. Connect a wire from the line terminal (L) to the line of the power source.

The 10.25 Amp Power Supply

Unlike the 5.25 Amp Power Supply, the 10.25 Amp Power Supply does not require a jumper to switch between
115 VAC and 230 VAC. The 10.25 Amp Power Supply provides an auto-detect feature that automatically
compensates for input voltages of 115 VAC or 230 VAC.

Provide an AC power connection to the terminal block from a 15 Amp branch circuit. To connect AC power to the
10.25 Amp Power Supply:

1. Connect a wire from the ground terminal ( ) to the grounding block of the cabinet box.

2. Connect a wire from the grounding block of the cabinet box to a ground. Provide this connection in close proximity to
the cabinet box.
3. Connect a wire from the neutral-terminal (N) to the neutral of the power source.
4. Connect a wire from the line-terminal (L) to the line of the power source.

Connecting Standby Batteries

The FireNET L@titude Fire Alarm Control Panel provides connections for two standby batteries. Refer to
Calculations for determining the minimum required battery capacity for the fire alarm system. If the required
battery capacity exceeds the space available in the cabinet, an appropriately-sized auxiliary UL listed battery
cabinet suitable for fire alarm service will be required. If needed, install that cabinet (wired close-nippled)
adjacent to the panel to minimize battery lead length.

WARNING! Battery terminals and leads are not power-limited. Shorts can cause a fire or an explosion. Use
extreme caution while connecting standby batteries.

Refer to Connecting Field Wiring for specific details about connecting the standby batteries.

1. Place two 12 VDC, VRLA, rechargeable, standby batteries in the base of the cabinet.
2. Orient terminals of the standby batteries so that the positive ( + ) terminal of one standby battery is facing the
negative ( - ) terminal of the other.

Hochiki America Corporation

Version 3.01 | June 2023 | MAN-1431HA
FireNET L@titude Fire Alarm Control Panel Installation

Installation

3. Connect the black wire of the power supply to the negative ( - ) terminal of Battery 1.
4. Connect the red wire of the power supply to the positive ( + ) terminal of Battery 2.
5. Connect the jumper wire from the ( + ) of Battery 1 to the ( - ) of Battery 2.
6. Route battery leads at least 0.25" from all other cabling.

The series connection described provides the 24 V standby voltage required by the panel. Do not connect the
two batteries in parallel. A parallel connection will not provide the 24 V required for operating the panel in a
standby condition.

The battery connections can be made while AC power on or off. If AC power is off, the battery connection will not
be recognized (and the unit will remain unpowered) until AC is restored. Once AC power is on and the batteries

Installing Optional Panel Modules

Panel modules are installed at the factory according to customer requirements. In some situations, it may be
necessary to install additional panel modules to satisfy site configuration requirements. This section describes
procedures for installing and configuring panel modules. Before installing optional panel modules, check and set
the DIP switch settings, if applicable.

DIP Switch Settings

Each panel module of the FireNET L@titude Fire Alarm Control Panel must contain a unique setting before
being connected to the Main Back Board. The binary setting of the DIP switch sets the specific address for the
panel module. The numeric order of the address setting between modules does not impact operation, but each
panel module must be assigned a separate / unique address.

The black portion of the DIP switch identifies the switch actuator.

Address 0 is shown above for illustrative purposes only. Address 0 should never be used.

For addresses above 15, switches 5 and 6 will need to be used.

l For address 16-31, switch 5 should be in the ON position. Switch 5 ALONE adds 16 to the address number. For
example, for address 20, set the switch position to address 4 shown above and switch 5 in the ON position.
l For address 32-47, switch 6 should be in the ON position. Switch 6 ALONE adds 32 to the address number.
l For address 48-63, switches 5 AND 6 should be in the ON position. Switches 5 and 6 TOGETHER adds 48 to the
address number.

Placement

To install modules on the FireNET L@titude Fire Alarm Control Panel:

1. Disconnect AC power and standby batteries prior to performing the module installation.

Overview

Notification Appliances
Notification Appliances operate with the FireNET L@titude Fire Alarm Control Panel in a special application or
regulated mode. The panel supports the simultaneous operation of regulated and special application outputs
between NACs.

The FireNET L@titude Fire Alarm Control Panel does not support the simultaneous operation of regulated and
special application outputs on the same NAC channel.

The panel supports special application outputs when operating:

l Gentex NAC devices

l System Sensor NAC devices
l Wheelock NAC devices
l Amseco NAC devices

Synchronization modules are not required and should not be used on special application outputs.

Synchronization

NAC synchronization can be performed across all NAC channels of an individual panel. NAC synchronization
cannot be performed across multiple panels.

The FireNET L@titude Fire Alarm Control Panel provides internal device synchronization between the outputs
of NACs when operating NAC devices from Gentex, Amseco, System Sensor, or Wheelock without the use of
an external synchronization module. External synchronization modules must not be used on the NAC outputs
when operating in the synchronization mode.

While most systems only use one device manufacturer, the L@titude panel can synchronize strobe devices
from any two manufacturers simultaneously. Devices from different manufacturers cannot be combined on the
same channel. Audible synchronization across manufacturers can only be accomplished between Gentex and
System Sensor.

The maximum number of strobes that can be synchronized for each brand is

l Amseco 2.37A / 88mA = 27 appliances

l Gentex 2.5A / 78mA = 32 appliances
l System Sensor 1.32A / 66mA = 20 appliances
l Wheelock 2.5A / 60mA = 41 appliances

Configuring NAC Outputs

Settings are provided in the panel GUI and Loop Explorer 2 for controlling the NAC outputs of the FireNET
L@titude Fire Alarm Control Panel. Selections are available in these utilities for providing outputs with
synchronization or various forms of constant power. Settings are also provided to allow the Alarm Silence
button to operate on the front panel in various modes.

Review the settings described below to configure each NAC output for operation.

Output Options General Alarm and Emergency are selected as default conditions. Alternative output options for this
field include Auxiliary Output, Pre-Alarm Output, Supervisory Alarm, and Trouble. Do not select the
General Alarm option if the NAC channel is to be controlled by cause-and-effect programming.
Strobe Strobe Output is not selected for operation as a default condition. Selecting this field allows the user
to define which synchronization protocol to be used.
NAC AUX 24V DC When the Strobe option above is not selected, Off is selected as the default operating condition.
Options for this output are continuous constant power, door holder, and resettable.

l Continuous constant power provides a voltage output comparable to AUX 24V.

l Door holder outputs lose power during fire alarm conditions and/or during AC power loss.
l Resettable causes power loss that lasts 4-5 seconds each time the panel is reset.
Alarm Silence Each NAC is configurable in reaction to the Alarm Silence button on the front panel. Edit properties of
the NAC channel in Loop Explorer 2. Select the box for Silencing if NAC silencing is required on this
channel. If Internal Synchronization Protocols are in use, an option is also available to Silence the
strobe. Failure to check the Strobe Silence box will cause horns to be silenced with continued
operation of the strobe.

For more details, refer to NAC Output Specifications.

Batteries
Refer to Calculations for determining the minimum required battery capacity for the fire alarm system.

WARNING! Battery terminals and leads are not power-limited. Shorts can cause a fire or an explosion. Use
extreme caution while connecting standby batteries. To ensure the battery is not short-circuited, do not connect the
batteries until all wiring of the battery cabinet and power supply is complete. The final wiring connection must be made
at the terminal of the battery.

An appropriately-sized auxiliary UL listed battery cabinet suitable for fire alarm

service will be required. When using a rack mount battery cabinet, it is
recommended to mount it directly below the FACP. Configure the battery cabinet
to provide 24VDC with a capacity meeting or exceeding the minimum required.
Refer to the documentation of the selected battery cabinet for specific wiring and
installation instructions.

Connect the 24V output of the battery cabinet to the BATTERY connections on
the FACP Power Supply module. The cable connecting the power supply and
battery must be a jacketed cable with a VW-1 flame rating. The cable between
the power supply and the battery cabinet should be kept as short as possible. It
must be no longer than 5 feet if using 12 AWG wire or 3 feet if using 14 AWG
wire.

NOTE The most commonly available wire that meets these requirements is
heavy duty outdoor extension cords of type SJ, which would need to be modified to
suit the application.

The FireNET L@titude Fire Alarm Control Panel contains fuses to protect it against overloads. During the life of
the product it may be necessary to replace one or both of the fuses. Replace fuses only after addressing the
cause which resulted in the fuse failure.

Battery Lead Fuse on 5.25A Power Supply

Failure of the battery lead fuse will result in a Battery Missing trouble. Verify that the fuse is the problem by
disconnecting the fused-lead from the battery, and measuring the resistance of the lead from end-to-end with
an ohm meter. The resistance should measure less than 1 ohm. If it measures higher, replace the fuse with a
UL listed slow blow fuse. After replacing the fuse, measure the resistance again. If it still measures higher than 1
ohm, replace the lead. Refer to the Equipment List for fuse part numbers.

Once the replacement is complete, reconnect the lead to the battery terminal and verify the Battery Missing
trouble has cleared.

Refer to Equipment List for parts supporting the assembly and connection of the fuse.

Replacing the Power Supply Fuse

Failure of the power supply fuse will result in a Power Failed trouble. Verify that the internal fuse is the problem
by checking that the proper AC voltage is present across the L & N terminals on the AC-in terminal block of the
power supply.

WARNING! This is high voltage area. An electrical shock hazard exists. Use extreme care.

If the terminals have proper AC voltage and the green AC NORM indicator on the power supply is not lit,
disconnect AC power at the source and replace the fuse.

Replace the power supply fuse by removing it from the fuse housing contained on the circuit board of the power
supply. Install the replacement fuse in the fuse housing and then test the power supply to determine that it
operates. The following figure illustrates the fuse of the power supply:

Removing the Power Supply Fuse

1. Turn off the AC power feed to the fire control panel. It is not necessary to disconnect the batteries.

Installing the Replacement Power Supply Fuse

WARNING! This is a high voltage circuit area. An electrical shock hazard exists in this area when the fire control
panel is operating. Do not replace the fuse while powering the fire control panel. Remove AC power at the source
before attempting to replace the fuse of the power supply.

1. Insert and center the replacement fuse in the upper housing.

For the 5.25A power supply, use only a UL listed 250V, 3A, slow blow, 5x20mm fuse.

For the 10.25A power supply, use only a UL listed 250V, 5A, slow blow, 5x20mm fuse.

2. Press the upper housing on the lower housing until the halves snap together. The following figure illustrates the
closed fuse housing:

3. Restore AC power.
4. Monitor the AC NORMAL and DC OUT ON LED indicators on the power supply of the FireNET L@titude Fire
Alarm Control Panel to determine that trouble conditions are not reported following fuse replacement.

Operating Constraints
Installation of the FireNET L@titude Fire Alarm Control Panel must include the operating constraints of the
system to maintain continuous signal monitoring and reporting. Operating constraints are based on the current-
driving capability of the panel while maintaining external loading caused by devices and cabling.

External loading must be selected within the limits of the FireNET L@titude Fire Alarm Control Panel to provide
continuous operation. External loading is caused by individual or multiple combinations of Signaling Line Circuits,
Notification Appliance Circuits, and Initiating Devices. It is also caused by the size and length of cabling
connections. Refer to Calculations to determine the appropriate size and length of cabling.

Appendix C: Calculations

APPENDIX C: CALCULATIONS
Current loading of the FireNET L@titude Fire Alarm Control Panel is limited to the capacity of the power
supplies. Installers must determine the loading placed on these power supplies by adding the sum of device
loads to the no load alarm current of the FireNET L@titude Fire Alarm Control Panel. The result obtained from
this calculation must be below the operating current of the power supply.

The 5.25 Amp Power Supply operates the fire control panel and external loads with 5.25 Amps and reserves
1.25 Amps for charging the standby batteries.

The 10.25 Amp Power Supply operates the fire control panel and external loads with 10.25 Amps and reserves
2.25 Amps for charging the standby batteries.

Current limits are provided in Specifications for outputs of the FireNET L@titude Fire Alarm Control Panel. Total
device currents must be below limits provided for all outputs of the fire control panel.

The calculation of total current loading must include the sum of device loads on the circuit outputs of the FireNET
L@titude Fire Alarm Control Panel. Circuits to be included in this calculation for total current loading are:

l SLC Loops
l NAC Outputs
l 24V OUT
l AUX 24V
l Peripheral Interface Modules
l Network Module
l Panel Standby and Alarm Currents

The current limits provided in Specifications are maximums for individual outputs of the fire control panel. These
output-levels are not intended to be summed together to determine the total current available from the FireNET
L@titude Fire Alarm Control Panel. Refer to these levels only when determining the limit of device-loading on
each output circuit.

 Appendix C: Calculations

SLC Loop Cabling

The FireNET L@titude Fire Alarm Control Panel requires that SLC Loops include wire gauge and lengths
specified in tables of this section.

The maximum allowable voltage drop of 6.4 V is necessary on the SLC loop to maintain the minimum device
operating voltage of 17 V. The worst case voltage drop occurs when the load is located at the farthest point from
the terminals of the fire control panel.

Example Voltage Drop Condition

The following example demonstrates the impact of cable size and length on output circuits. A twin-wire of 16
AWG cabling is connected to SLC loop 1. The length of the 16 AWG cable is 1000 ft (305 m) and the device-load
on the loop is 400 mA. The device-load of 400 mA is determined from manufacturer data sheets. The following
figure illustrates the example SLC voltage drop condition of 16 AWG cable:

A voltage-drop of 1.6064V DC is determined from the table of 16 AWG cable for a single wire length of 1000 ft
(305 m) and a load of 400 mA. The resistance of one wire of the 16 AWG cable is 4.016 Ω at 1000 ft.

Voltage-drop of the twin Conductor Cable

(Vconductor 1 + Vconductor 2 ) = (1.6064V DC + 1.6064V DC) = 3.2128V DC

Appendix C: Calculations

Voltage at the load

Vload = Vsource - (Vconductor 1 + Vconductor 2 ) = 24V DC - (1.6064V DC + 1.6064V DC) = 20.7872V DC

A voltage of 20.7872 VDC is available to operate the device at this circuit location.

Shading of the SLC tables identify cable length and load combinations that are not permitted for SLC loop
devices. Light shading represents cable lengths that are not permitted when SLC circuits contain five or more
isolators. Dark shading represents cable lengths that are not permitted without the connection of isolators in the
SLC circuit.

Twin cables are connected to SLC loop terminals of the FireNET L@titude Fire Alarm Control Panel. Data
provided in SLC tables of this section represent resistance and voltage from a single cable-conductor.
Resistance and voltage levels obtained from these tables must include the secondary conductor of the twin cable
during the evaluation process. SLC tables are provided for the following recommended wire gauges:

14 AWG 2.525 Ohms / 1000 ft

16 AWG 4.016 Ohms / 1000 ft
18 AWG 6.385 Ohms / 1000 ft

NAC Cabling
The FireNET L@titude Fire Alarm Control Panel requires that NAC circuits include wire gauge and lengths
specified in tables of this section. Shading of the tables identify cable length and load combinations that are not
permitted for NAC devices.

Twin cables are connected to NAC terminals of the FireNET L@titude Fire Alarm Control Panel. Data provided
in the tables of this section represent resistance and voltage from a single cable-conductor. Resistance and
voltage levels obtained from these tables must include the secondary conductor of the twin cable during the
evaluation process.

Cable length values in the tables represent worst case conditions with the total load at the farthest point from
terminals of the fire control panel. Voltage drops are represented with a depleted battery of 20.4V. Minimum
output voltage is 20V. maximum allowable voltage drop is 4V to ensure a minimum of 16V at the device.

Tables are provided for the following recommended wire gauges:

12 AWG 1.588 Ohms / 1000 ft

14 AWG 2.525 Ohms / 1000 ft
16 AWG 4.016 Ohms / 1000 ft

AUX 24V Cabling

The FireNET L@titude Fire Alarm Control Panel requires that AUX 24V circuits include wire gauge and lengths
specified in tables of this section.

Twin cables are connected to AUX 24V terminals of the FireNET L@titude Fire Alarm Control Panel. Data
provided in AUX 24V tables of this section represent resistance and voltage from a single cable-conductor.
Resistance and voltage levels obtained from these tables must include the secondary conductor of the twin cable
during the evaluation process.

Cable length values in the tables represent worst case conditions with the total load at the farthest point from
terminals of the fire control panel.

AUX 24V tables are provided for the following recommended wire gauges:

12 AWG 1.588 Ohms / 1000 ft

14 AWG 2.525 Ohms / 1000 ft
16 AWG 4.016 Ohms / 1000 ft

Determining the Total Load Current

The following example demonstrates the process for determining the total load current of the FireNET L@titude
Fire Alarm Control Panel:

1. Identify the current draw of each device on the circuit connection.

2. Add the device currents together in each circuit connection.
3. Compare the sum of the device currents with the current limit of each circuit connection to verify that the summed
level is below the current limit value.
4. Add the device load currents together that were obtained for each of the circuit connections:

Circuit Connection Maximum Current Limit Example Load Current

SLC Loop 1 400 mA 150 mA
SLC Loop 2 400 mA 50 mA
AUX 24V 900 mA 0
NAC 1 2.5 A 750 mA continuous DC
NAC 2 2.5 A 925 mA continuous DC
Total Device Load 1.875 A

5. Add the Total Device Load to the no-load alarm current to obtain the Total Load Current.
6. Total Device Load + FireNET L@titude Fire Alarm Control Panel No-Load = Total Load Current

1.875 + 200 mA = 2.075 A

Total Load Current = 2.075 A

7. Verify that the current level is below 4 Amps: 2.075 A < 4 A

8. This example demonstrates that device loading does not exceed the 4 Amp capacity of the power supply.

1.25 A of the 5.25 A power supply is reserved for battery charging.

Refer to Specifications for the maximum current limits provided in the example calculation above.

Appendix C: Calculations

Determining the Standby Battery Capacity

This section provides guidelines for determining the standby battery rating. For power supply applications that do
not include fire alarm equipment, alarm current is the dynamic current present during operation of the power
supply. Standby current is the static current present when the power supply is not operating an alarm.

Battery Rating Equation

The equation below describes the method for determining the amp hour rating of the standby batteries:

Battery Rating = ( Battery De-Rating Factor ) x [ ( Standby amp hours ) + ( Alarm amp hours )]
OR
Battery Rating = ( Battery De-Rating Factor ) x [ ( 24 hours x Standby-Current ) + ( 5 Minutes x Alarm Current)]
where the battery de-rating factor = 1.2 and 5 minutes = 5 / 60 minutes = 1/12 = .0833 hours

To determine the amp hour rating of standby batteries:

1. Record the standby current of the power supply.

2. Record the standby current of the fire control panel. This current includes the LCD Main Processor Board, the Main
Back Board, System A Panel Module, and System B Panel Module. It does not include current of the power supply
and circuit boards in Slots C through F.

3. Record the standby current of circuit boards populating Slots C through F.

4. Record the standby current of SLC, NAC, and auxiliary devices.
5. Total standby currents.
6. Record the alarm current of the power supply.
7. Record the alarm current of the fire control panel. This current includes the LCD Main Processor Board, the Main
Back Board, System A Panel Module, and System B Panel Module. It does not include current of the power supply
and circuit boards in slots C through F.

8. Record the alarm current of circuit boards populating slots C through F of the panel.
9. Record the alarm current of SLC, NAC, and auxiliary devices.
10. Total alarm currents.
11. Multiply the total standby current with the standby-time of 24, 48, or 72 hours to provide the result in amp hours.
12. Multiply the total alarm current with the alarm time 5 or 15 minutes to provide the result in amp hours.
13. Combine the sum of amp hours for total standby and alarm.
14. Determine the minimum required amp hour capacity of the standby battery by multiplying the combined Amp hours
with the 1.2 de-rating factor.
