NFC-BDA-25/70V Audio Amplifier Modules

An optional second audio amplifier can be plugged into connectors J10 & J11 located in the upper right of the main control board in the 
NFC-50/100. This amplifier also provides 50 watts of power at 25 V

RMS

 or 70 V

RMS

, depending on the model, and can therefore be used 

to expand system power to 100 watts (providing dual 50 watt speaker circuits) or it can be used as a backup amplifier. The output is  
power-limited (Class 2) and speaker circuit connections to it are provided on the main control board and optional speaker circuit 
expander module. The circuit can be wired for Style Y (Class B) or Style Z (Class A) operation.

LEDs are provided to indicate Amplifier Supervision (green indicates amplifier is functional) and Circuit Trouble (yellow indicates field 
wiring fault or amplifier fault). The LEDs are only visible with the panel door open.

NFC-CE6 Circuit Expander Module

This optional module plugs into connector P1 in the upper middle of the main control board. The NFC-CE6 adds three primary speaker 
circuits to the NFC-50/100. The NFC-CE6 adds three secondary circuits to the system when the NFC-BDA-25/70V Audio Amplifier 
Module is also installed.

NFC-XRM-70V Transformer 70.7 V

RMS

This optional module plugs into connector J12 of the main control board and provides conversion for the integral audio amplifier from 
25 V

RMS

 to 70.7 V

RMS

 at full rated 50 watts output power.

NFC-FFT Fire Fighter Telephone

The NFC-FFT has a telephone handset and user interface that allows an operator to communicate with remotely located telephone hand-
sets in a building. It is housed in its own cabinet with key lock. It requires an external operator interface power connection (24 volts DC) 
from the NFC-50/100 main console or it may be powered from an external 24 VDC power supply such as HP300ULX. The NFC-FFT 
provides supervision, annunciation, and control for the local handset and for up to 24 remote telephone handsets. It provides indications 
of phone activation and corresponding trouble conditions. Refer to the 

NFC-FFT Fire Fighter Telephone

 manual. Not for use in UL2572 

Mass Notification or Canadian applications. 

NFC-50DA Distributed (Remote) Audio

The NFC-50DA is a 50-watt audio amplifier (audio booster) with its own cabinet and key lock. It requires an external data bus connec-
tion and an external audio riser connection from the NFC-50/100 main console. The unit comes standard with 4 speaker circuits. An 
option card, NFC-CE4, provides 4 more speaker circuits for a total of 8. Speaker circuits are activated/de-activated manually or automat-
ically by the NFC-50/100 main console. The unit is capable of either 25 V

RMS

 or 70.7 V

RMS

 operation. Refer to the 

NFC-50/125DA Dis-

tributed Audio

 manual. Not for use in Canadian applications. 

NFC-125DA Distributed (Remote) Audio

The NFC-125DA is a 125-watt audio amplifier (audio booster) with its own cabinet and key lock. It requires an external data bus con-
nection and an external audio riser connection from the NFC-50/100 main console. The unit comes standard with four (4) speaker cir-
cuits. An option card, NFC-CE4, provides 4 more speaker circuits for a total of eight (8). Speaker circuits are activated/de-activated 
manually or automatically by the NFC-50/100 main console. The unit is capable of 25 V

RMS

 operation. Refer to the 

NFC-50/125DA 

Distributed Audio

 manual. Not for use in Canadian applications. 

NFC-50/100DA Distributed (Remote) Audio

The NFC-50/100DA is a 50/100-watt audio amplifier (audio booster) with its own cabinet and key lock. It requires an external data bus 
connection and an external audio riser connection from the NFC-50/100 main console. The NFC-50/100DA is capable of producing up 
to 100 watts of audio power. The amplifier functions as 50 watts with 50 watts as backup, 100 watts with no backup or 100 watts with 50 
watts backup using NFC-BDA-BU. The unit comes standard with 8 speaker circuits. Speaker circuits are activated/de-activated manu-
ally or automatically by the NFC-50/100 main console. The unit is capable of either 25 V

RMS

 or 70.7 V

RMS

 operation. Refer to the 

NFC 

Distributed Audio

 manual. Not for use in Canadian applications. 

NFC-RM Remote Microphone

The NFC-RM has a hand held microphone and is housed in its own cabinet with keyed lock. It requires an external data bus connection, 
an external audio riser connection, and an external operator interface power connection (24 volts DC) from the NFC-50/100 main con-
sole. ALL CALL paging can be broadcast over the speaker circuits by depressing the microphone's push-to-talk switch. Not for use in 
UL2572 Mass Notification or Canadian applications.

NFC-RPU Remote Page Unit

The NFC-RPU has a hand held microphone and 8 message buttons. It is housed in its own cabinet with a keyed lock or thumb lock 
(requires AHJ approval). It also has a 9th button that will activate a monitor module mounted inside the cabinet. This may be used for 
HVAC shutdown applications when the monitor module is connected to the FACP SLC polling loop. The remote page unit requires an 
external data bus connection, an external audio riser connection, and an external operator interface power connection (24 volts DC) from 
the NFC-50/100 main console. ALL CALL paging can be broadcast over the speaker circuits by depressing the microphone's push-to-

NOTE:

Any combination of up to eight audio boosters comprised of NFC-50DA, NFC-125DA, and NFC-50/100DA can be used in the 

system. Their external data bus addresses must be unique and must be sequential. Addresses are set via dipswitches on each unit's PC 
board. Refer to Section 2.14 on page 48.
