Mass notification systems are becoming an integral part of both emergency and non-emergency communications for organizations of all sizes and all industries. These notification systems integrate fire, security, and communications to provide emergency and non-emergency notification.

Mass notification systems can be used in a single building or in multiple building on a campus.  These systems may also use illuminated text signs to direct occupants of a building to evacuate and where to exit.

The LEMD Emergency Message Display is an LED illuminated text sign designed to comply with UFC requirements for mass notification systems.
