The AARC-EVAC™ ARX40-FB -R Standalone Wireless Linked
Emergency Visual Alert Flashing Beacon Units, all incorporate an in built Battery Backup UPS, 4 x Flashing Beacons and a Repeater
Transmitter. 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 a full standalone network
of units to provide for redundancy if the PA system fails for any
reason. These units are used in very high noise environments
where use of audio warnings is impracticable or to assist the
hearing impaired to be alerted to an emergency situation.
