NOTIFIER NFV-25, 50DAZS Distributed Audio Panel

NOTIFIER NFV-25, 50DAZS Distributed Audio Panel

General

The Notified FireVoice-25/50DAZS (NFV-25/50DAZS) is a compact, distributed audio (DAZS) panel that expands the eight speaker circuits found in the FireVoice-25/50ZS (NFV25/50ZS) audio control panel with an additional eight speaker circuits. Up to two NFV-25/50DAZS units wired Class B or up to five NFV-25/50DAZS units wired Class A can be linked to a master NFV-25/50ZS providing a total capacity of 24 speaker circuits. The speaker circuits can be manually activated via the switch module on the master NFV-25/50ZS panel or automatically via the serial communications link.

The audio riser input provides automatic gain control (AGC) which compensates for any audio signal loss due to circuit loading or cable length, to ensure delivery of a full output signal to the speakers. For systems requiring 24-hour backup, the built-in power supply and battery charger are able to charge up to 18 AH batteries.

Other options include a 25 Watt, 25 VRMS audio amplifier for system expansion to 50 Watts (providing dual 25 Watt speaker circuits) or as a secondary, backup amplifier. Optional 70.7 VRMS conversion modules are available for applications requiring 70.7 VRMS speakers.

Significant technological enhancements, set the NFV-25/ 50DAZS Series apart from other voice panels. The NFV-25/ 50DAZS has full supervision in both active alarm and standby conditions. Independent power feeds to each amplifier ensures that a short circuit in one amplifier will not shut down the other. Full output power (25 watts per amplifier) is generated with the optional 70.7 VRMS transformer module during low battery conditions. Additionally, modern integrated circuits, as opposed to transformer technology, amplifies audio for very low signal distortion.

Suitable applications include, but are not limited to: schools, auditoriums, dormitories, theaters, restaurants, places of worship, motels/hotels, office buildings, and factories.
