Optional Modules
ACC-AAM25: 25 watt, 25 VRMS audio amplifier module.
Field-programmable for system expansion to 50 watts (provid-
ing dual 25-watt speaker circuits) or as a backup to the primary
25-watt amplifier where required. Single Class A or Class B
speaker circuit. Plug-in-style terminal blocks for ease of ser-
vice and maintenance. Fully supervised and power-limited.
Diagnostic LEDs include: yellow “trouble” LED (cable fault, 70
VRMS fault, amp fault) and green “amp functional” LED.
FC-XRM70: Converts 25 VRMS audio outputs to 70.7 VRMS
for retrofit applications. Plugs directly on ACC-AAM25 mod-
ule(s), allowing independent conversion to 70.7 VRMS.
FC-LPS: Local digital message playback for user review of
field-recorded custom messages.
BAT Series: Two batteries required. See FACP manual for
specific current requirements. See data sheet for overview of
batteries.
NFV-TR: Optional trim ring for semi-flush mounting.
VEC-RM: Optional remote microphone, includes backbox.
Only one VEC-RMper system.

Temperature and Humidity Ranges
This system meets NFPA requirements for operation at 0 –
49°C/32 – 120°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 tempera-
ture 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 – 27°C/60 – 80°F.
Standards and Codes
The NFV-25/50 complies with the following standards: NFPA
72 National Fire Alarm Code; NFPA 101 Life Safety Code; UL
864 Standard for Control Units for Fire Alarm Systems.

Application Examples
The FireVoice-25/50 is a voice evacuation control panel which
can be used with a variety of FACPs for emergency audio
messages. Two typical application examples follow.
One Speaker Circuit
Single output zone, single input circuit (SEE FIGURE 1). A
very basic application is one NFV-25/50 with one amplifier and
a single speaker circuit. This configuration is suitable for small
facilities requiring no more than 25 watts of output power. A
single fire evacuation message will be initiated during an alarm
condition from the host FACP or can be manually started with
a message push-button.
The NAC from the host FACP is connected to CMD1. The
CMD1 “out” terminals are then terminated with an end-of-line
resistor for the FACP’s Style Y NAC, or the terminals are wired
back to the host FACP for a Style Z NAC. S3 DIP switches “1”,
“2”, and “3” are set to OFF; this selection sends a 60-second
message to the speaker circuit when the CMD1 input is acti-
vated. The S5 DIP switch “5” is set to OFF; this selection acti-
vates the CMD1 input by a reverse-polarity condition. CMD3,
CMD4, and CMD5 inputs require end-of-line resistors.
The system may also be manually activated from the keypad.
Press the Building Speakers button, then press the Fire Mes-
sage button.
Or use the microphone to make an announcement.
