NFV 25 50DA Audio Panel Notifier FireVoice 25 50DA NFV 25 50DA is a compact Audio DA panel which is designed to interface the FireVoice 25 50 NFV 25 50 Series audio panels to audio in systems that require more than 25 watts NFV 25 50DA is offered in a self contained modular that includes a single channel 25 Watt 25 VRMS amplifier An optional 25 Watt 25 VRMS audio amplifier available to expand the NFV 25 50DA to 50 Watts provid dual 25 Watt speaker circuits or as a secondary backup NFV 25 50DA can be used to distribute voice evacuation throughout a facility The audio riser input provides gain control AGC which compensates for any signal loss due to circuit loading or cable length to delivery of a full output signal to the speakers For requiring 24 hour backup the built in power supply battery charger are able to charge up to 18 AH batteries to 25 NFV 25 50DA units can be connected to an NFV master unit If all units are equipped with the optional amplifier the total wattage can be 1300 watts options include a digital message generator module a factory recorded voice with field record and play capability up to five distinct messages Optional 70.7 conversion modules are available for applications 70.7 VRMS speakers technological enhancements set the NFV 25 Series apart from other voice panels The NFV 25 has full supervision in both active alarm and standby Independent power feeds to each amplifier that a short circuit in one amplifier will not shut down other Full output power 25 watts per amplifier is gener with the optional 70.7 VRMS transformer module during battery conditions Additionally modern integrated cir as opposed to transformer technology amplifies audio very low signal distortion applications include but are not limited to schools dormitories theaters restaurants places of motels hotels office buildings and factories 25 watts of 25 VRMS audio power expandable to 50 watts panel Automatic gain control AGC Optional 70.7 VRMS conversion module available for each primary AC power supply and secondary battery circuit Designed for maximum system flexibility and expansion Unobstructed module access and removable terminal for ease of service and maintenance Optional digital message generator module FC MGM factory prerecorded emergency evacuation message custom 60 second recorded message capacity Five Command Input Circuits C 20 Control Systems Field selectable message and field recording capability optional FC MGM RCA jack or mini audio input for connection to external audio devices Built in alert tone generators with steady slow whoop or chime tones Alert tone selection may be field programmed to conform ANSI S3.41 Audible Emergency Evacuation Signal Pattern per NFPA diagnostic LEDs include Power System Trouble Message
