The Notifier NFC-50DA is a 50-watt distributed audio amplifier for FirstCommand voice-evacuation systems. Specifically, it works with the NFC-50/100(E) Emergency Command Center. As a result, designers can place audio power near the protected area. Therefore, riser wiring drops and voltage drop stays inside spec.
This amplifier ships with four built-in, fully supervised speaker circuits as standard. In addition, the optional NFC-CE4 module expands the unit to eight speaker circuits. Furthermore, the NFC-50DA is field-selectable for 25 Vrms or 70.7 Vrms output. As a result, it matches most existing speaker risers.
