Speaker unit for flush-mounting voice alarm systems
The RWM 412 T/EN speaker unit, featuring a self-extinguishing ABS UL94-V0 housing and a metal front grille, has a loudspeaker with a transformer for constant-voltage lines (50, 70, 100V); the output power is adjustable (12, 6 or 3W). The fixing systems enables it to be flush-mounted on a wall or in a false ceiling. These speaker units have been developed specifically for use in emergency and evacuation systems and each has its own ceramic terminal strip and thermal fuse. These ensure the protection of the line connecting the loudspeakers if a fire puts one or more of the speaker units connected to it out of use.
