Voice alarm loudspeaker
Voice alarm loudspeakers are specifically designed for use in buildings where performance of systems for verbal evacuation announcements is governed by regulations. The LC2‑PC30G6‑4 is designed for use in voice alarm systems.
The loudspeaker has built‑in protection to ensure that, in the event of a fire, damage to the loudspeaker does not result in failure of the circuit to which it is connected. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation. It is standard fitted with a back‑can enclosure to increase protection of the cable termination.
The loudspeaker has an emergency compliant ceramic screw‑terminal block and thermal fuse.
