Section 1: Product Description
The Notifier FirstCommand NFC-50/100 is a single channel, 50 watt, 25 V
RMS
, emergency voice evacuation panel that may be used for
fire applications, mass notification applications, or both. The NFC-50/100 comes standard with one speaker circuit. The panel provides
the ability to record fourteen field programmable messages (up to 60 seconds each) with an integral microphone or from an external
audio source. An integral power supply with battery charger supplies operational power. A 50 watt audio amplifier is built into each
panel. An optional second 50 watt amplifier (NFC-BDA-25/70V) is also available for backup purposes or to provide an additional 50
watts. The backup amplifier is available in either 25 volts or 70 volts depending on which application is necessary.
Automatic activation of the NFC-50/100 by an FACP is possible via eight Command Input Circuits (CMD) or via the ACS/ANN Bus
serial communications link from the FireWarden-100X, FireWarden-100-2, NFS2-640, and NFS-320 FACPs.
Two Command Input Circuits can be independently field programmed for activation by an FACP Notification Appliance Circuit reverse
polarity or by closure of a supervised normally open contact and six Command Input Circuits activate on contact closure. CMD 1 and
CMD 2 provide terminals for NAC input and output to allow installation of the audio panel anywhere along the NAC circuit being used
to activate it.
If the message generator fails, the system automatically reverts to a backup tone generator.
Power is fed independently to each amplifier so that a short circuit in one amplifier will not shut down the other. Full output power of 50
watts per amplifier is generated while in a low battery condition. Power is not diminished when the optional 70 V
RMS
transformer mod-
ule is installed. Audio is amplified utilizing modern integrated circuits as opposed to transformer technology. This provides for very low
signal distortion for crystal clear audio.
Primary applications for the audio panels include protecting structures such as military facilities, restaurants, schools, auditoriums,
places of worship, buildings with occupancies over 50, etc. The NFC-50/100 is designed to interface directly to addressable or conven-
tional (CMD inputs 1-8) fire alarm control panels or can be used with the NFC-50/125DA panel to distribute audio in systems that
require more than 100 watts.
For Canadian applications, refer to Appendix C on page 83.
