The 500 W AT-FR rack type fire emergency broadcasting panel is the top-power model of the series. Installed in a 19" cabinet, it works as the core host for large-area fire emergency broadcasting systems in malls, airports, stations, industrial plants and stadiums.
It connects to fire alarm linkage controllers, output modules, constant-voltage speakers and expansion amplifiers. Under fire conditions, the panel broadcasts pre-recorded evacuation messages or live voice instructions to a large number of speakers, ensuring clear guidance across the whole building.
