10 NFS2-3030 Listing Document — P/N LS10006-051NF-E:F2 5/19/2022

1.3 Connecting Power Sources and Outputs

1.3.1 Primary Power Source

The NFS2-3030 uses the AMPS-24/E addressable power supply. The AMPS-

24/E provides a total of 5A of power to the CPU and can recharge batteries

ranging from 7 to 200 amp-hours. If the AMPS-24/E is mounted in a separate

cabinet, power supply must be within 20 feet of the fire panel enclosure and

wiring must be in conduit. To connect the AMPS-24/E to the NFS2-3030,

perform the following steps:

1. Connect J13 on the CPU2-3030(CPU2-3030DC for Canada Only) to

TB1 on the AMPS-24/E power supply using cable 75637.

2. Before connecting the batteries, check AC power to the system. (See

below.)

3. Connect the batteries.

For additional information and to determine whether or not the system

requires an auxiliary power supply, refer to the AMPS-24/E Manual docu-

ment number 51907.

1.3.2 Checking AC Power

Table 2 contains a checklist for checking AC power applied to the system.

1.3.3 Secondary Power Sources

Batteries provide +24 VDC secondary (backup) power. Batteries can be installed in the fire panel cabinet or in an optional battery backbox. All wiring

must be encased in conduit. A secondary power source is required to support the system during primary AC loss. Refer to the manual for the AMPS-24/

E Manual, document number 51907, for additional information on connecting secondary power.

1.3.4 External Power Sources

Additional power can be provided via auxiliary power +24 VDC power supplies that are UL/ULC-listed for fire protective service. For additional

information on connecting auxiliary power supplies, follow connection procedures specified in the auxiliary power supply manual.

1.3.5 Accessory Power for Peripheral Devices

TB6 on the CPU draws power from the primary, secondary and external sources to pass +24 VDC power to devices within the same enclosure as the

CPU. If those devices have outputs, those outputs must be power-limited (Class 2). Power rating is limited to the AMPS-24/E primary power source

(+24 VDC, 5 Amps max) TB3 on the AMPS-24/E provides a secondary Accessory power source. Refer to the AMPS-24/E Manual for further details.

WARNING: DISCONNECT ALL POWER SOURCES

SEVERAL SOURCES OF POWER CAN BE CONNECTED TO THE CONTROL PANEL. BEFORE SERVICING THE CONTROL

PANEL, DISCONNECT ALL SOURCES OF INPUT POWER INCLUDING THE BATTERY. WHILE ENERGIZED, THE CONTROL

PANEL AND ASSOCIATED EQUIPMENT CAN BE DAMAGED BY REMOVING AND/OR INSERTING CARDS, MODULES, OR

INTERCONNECTING CABLES.

NOTE: UL 2610 Proprietary Burg requires 24 hours of standby

power

CAUTION: BATTERY CONNECTION

WHILE CHECKING POWER, ENSURE BATTERIES ARE NOT CONNECTED.
