Notifier’s First Command NFC-50DA(E), NFC-50/100DA and NFC-125DA(E) are intelligent 50 watt, 100 watt, and 125 watt amplifiers that are 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) is capable of producing 50 watts of total power and includes four built-in, fully supervised speaker circuits/zones. The NFC125DA(E) is capable of producing 125 watts of total power with four built-in, fully supervised speaker circuits/zones. Both amplifiers are expandable to include eight speaker circuits when an optional NFC-CE4 module is installed.
