The AARC-EVAC™ ARX82-FB-R, ARX83-FB-R & ARX84-FB-R Standalone Wireless Linked Emergency Alert Siren &
Message Broadcast Units with Flashing Beacons & Repeater Transmitter, incorporates an in-built 110-240V Din Rail
mounted Power Supply and Battery Backup UPS. They are fully self-contained making them ideal for use in locations
where there is no existing PA system, or to cover areas not serviced by a PA system or as part of a full standalone
network of AARC-EVAC units to provide for redundancy if the PA system fails for any reason.
