Alert Beacons® are designed to serve campuses, military bases, and other large facilities that presently lack an in-building emergency notification system and where retrofitting a conventional voice public address system is impractical and cost prohibitive. Alert Beacons are most effective when wall-mounted in prominent locations throughout the facility. In the event of an emergency, these devices flash and sound to capture the attention of building occupants at a distance and display a custom message about the nature of the emergency and how to respond.
