The Notifier NFC-50/100 is an emergency voice-evacuation and mass-notification control panel in a surface-mount steel enclosure. It includes a 50-watt, 25 V RMS amplifier that drives one supervised Style Y/Z speaker circuit and stores fourteen field-programmable digital messages of up to 60 s each, complete with selectable alert tones. Standard features are an integral supervised microphone, eight command inputs, a 2.0 A synchronized NAC output, three Form C status relays, 500 mA of auxiliary 24 V power, and a USB/web programming interface. System capacity expands to 100 W and eight speaker zones with optional amplifier and circuit-expander modules, while the on-board charger supports two 18 Ah batteries (26 Ah charging capacity) for backup operation.
