The 350 W AT-FR rack type panel is installed in a standard 19" cabinet and acts as the main host of a fire emergency broadcasting system. By connecting to a fire alarm linkage controller, output modules, constant-voltage speakers and expansion amplifiers, it delivers powerful voice evacuation for medium-size commercial and industrial buildings.
On receiving an emergency signal, the panel switches automatically to emergency broadcasting and plays pre-recorded fire evacuation messages or live MIC announcements, guiding people to safe exits.
