Description
The FireVoice-25/50 (NFV-25/50) is a state-of-the-art, single or dual-circuit (25 watts each) Emergency Voice Evacuation Control Panel (EVAC). The NFV-25/50 records five field-programmable messages (up to 60 seconds total message duration) with an integral commercial-grade emergency communications microphone or from an external audio source. Significant technological enhancements set the NFV-25/50 apart from other EVAC panels – these include full supervision in both active (alarm or music) and standby conditions, supervision of amplifier outputs, field wiring, message generator, all tone generators, and the microphone. The integral power supply charges up to 18 AH batteries, which can be housed in the NFV-25/50 cabinet.
The NFV-25/50 is suitable for use as an adjunct (slave or stand-alone) to most UL-Listed Fire Alarm Control Panels (FACPs). An optional 25 watt, 25 VRMS audio amplifier is available for system expansion to 50 watts (providing dual 25 – watt speaker circuits) or as a secondary amplifier in jurisdictions requiring backup. A 70.7 VRMS converter is also available for independently converting amplifiers to meet retrofit needs.
A host of field-programming options, including the capability of five custom messages (fire, tornado, evacuation, hazmat, non-fire, multi-language, etc.) make the NFV-25/50 the most versatile voice evacuation system available.
Suitable Applications include schools, auditoriums, dormitories, theatres, restaurants, places of worship, lodging, office buildings, and factories.
