Distributed Audio Amplifier

The NFC-50/100DA, 50/100 watt intelligent amplifiers are used for audio message amplification and designed as self-contained units and can be conveniently installed near an area of protection to reduce wiring demands for speaker circuit outputs.

The Notifier's first command NFC-50/100DA are intelligent 50 watt and 100 watt amplifiers that are used with the NFC-50/100 Emergency Command Center.

These distributed audio amplifiers amplify an audio message for distribution throughout a facility when additional audio power is required. They are designed as self-contained units and can be conveniently installed near an area of protection to reduce wiring demands for speaker circuit outputs. For applications that require additional capacity, expand the First Command system's total wattage and speaker circuit capability.
