Product Details
The Notifier NFC-50DA is a 50-watt distributed (remote) audio amplifier for FirstCommand NFC-50/100 systems. It includes four fully supervised speaker circuits selectable for 25 Vrms or 70.7 Vrms operation and supports Class A (Style Z) or Class B (Style Y) wiring. A built-in power supply and charger supervise local backup batteries (up to two 18 Ah in the cabinet, 35 Ah charging capacity), while data and audio riser connections keep the amplifier under full control and monitoring by the primary console. Installing the optional NFC-CE4 module expands the unit to eight speaker circuits, and up to eight distributed amplifiers, any mix of NFC-50DA, NFC-50/100DA, or NFC-125DA, can be added to a single system for greater audio power and zoning flexibility.
