Notifier’s FirstCommand NFC-50DA(E), NFC-50/100DA, and NFC-125DA(E) are intelligent 50 watt, 100 watt, and 125 watt amplifiers used with the NFC-50/100(E) 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.

Each NFC-50DA(E) produces 50 watts of total power and includes four built-in, fully supervised speaker circuits/zones. The NFC-125DA(E) produces 125 watts of total power with four built-in, fully supervised speaker circ style=”font-size:16px;”uits/zones. Both models are expandable to eight speaker circuits with the optional NFC-CE4 module.

The NFC-50/100DA can be configured for 50 watts primary and 50 watts backup, or 100 watts primary with 50 watts backup. It comes standard with eight built-in, fully supervised speaker circuits/zones.

Up to eight NFC-50DA(E)s, NFC-50/100DAs, or NFC-125DA(E)s can be connected to the NFC-50/100(E), providing a total of 1100 watts of audio power and up to 24 speaker circuit outputs.

These amplifiers are connected via data and audio riser buses to the NFC-50/100(E) console, with built-in power supplies, battery chargers, and full supervision for trouble conditions.
