VXP-25/50
Distributed Audio Voice Transponder
Section: Voice Control Systems
PRELIMINARY
GENERAL
The VXP-25/50 Distributed Audio Voice Transponder is a dual-channel, 25 watt
(expandable to four-channel, 50 watt), 25 VRMS, distributed audio, emergency
voice evacuation panel which is compatible with existing NOTIFIER voice
equipment. The VXP-25/50 can be used to distribute voice evacuation audio over
a building’s speaker system. A separate custom power supply module (FC-PSM)
with battery charger is included. An optional second audio amplifier (FC-
AAM25) is available as a backup to the primary amplifier or to expand speaker
power to 50 watts (providing dual, 25-watt speaker circuits). This same
25-watt amplifier can also be used for backup purposes when the panel is
configured for 50-watt operation. 70 VRMS conversion modules (FC-XRM70) are
also available as options for installations where 70 VRMS speakers are to be
installed or already exist. The modular design permits greater installation
and servicing ease.
The FC-VTM Voice Transponder Module, supplied with the BE-VXP basic equipment
kit, allows connection to a NOTIFIER addressable Fire Alarm Control Panel SLC
loop. The five SLC device addresses for the VXP are set using the FC-VTM
rotary switch for the “10’s” address and individual slide switch for a “1” or
“5” at the “1’s” address. The SLC/FlashScan control points permit VXP
activation from a control panel connected to the SLC loop. This module also
provides two firefighter-telephone or NAC circuits (requires an APS-6R power
supply).
Significant technological enhancements set the VXP apart from other
distributed audio voice panels. These enhancements include full supervision in
both active alarm and standby conditions. Supervision is provided for:
amplifier outputs, field wiring (shorts and opens), optional message generator
(FC-MGM), all tone generators.
If the single audio riser input fails, the VXP can be programmed to switch to
the optional FC-MGM Message Generator Module or built-in tone generator. If
the FC-MGM fails or is not installed, the two tone generators on the main
circuit board can be automatically switched in as backups.
Power is fed independently to each amplifier so that a short circuit in one
amplifier will not shut down the other. Full output power of 25 watts per
amplifier is generated while in a low battery condition. Power is not
diminished when the 70 VRMS option is installed. Audio is amplified from
modern integrated circuits instead of transformer technology. This provides
very low signal distortion for crystal-clear audio.
The VXP is designed to interface directly to the VEC-25/50 Voice Evacuation
Control Panel and compatible NOTIFIER voice alarm equipment such as the AMG
and ATG.
