Notifier NFC-BDA-25V.

The Notifier FirstCommand NFC-50/100 i s a single channel, 50 watts, 25 VRMS, 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 can record fourteen field-programmable messages (up to 60 seconds each) with an integral microphone or external audio source. An integral power supply with a 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). It’s available for backup purposes or to provide an additional 50 watts. Depending on the application, the backup amplifier is available in 25 or 70 volts.
An FACP can automatically activate the NFC-50/100 via eight Command Input Circuits (CMD) or 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 closing 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. 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 VRMS transformer module 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.
