Notifier NFC-50/100DA Distributed Audio Amplifiers 120VAC

The Notifier NFC-50/100DA is a FirstCommand distributed audio amplifier for 120 VAC, 60 Hz, used with the NFC-50/100(E) Emergency Command Center.

It amplifies audio messages for distribution throughout a facility when more audio power is needed. As a self-contained unit it can be mounted near the protected area to reduce speaker wiring. It connects to the data bus and audio riser bus of the NFC-50/100(E) console, has its own power supply and battery charger, and is fully supervised by the console. For survivability it can be set up with primary and backup amplifier power.
