About Bosch LC1-UM06E8

The range offers a choice of five loudspeakers distinguished by input power, opening angle and sound reproduction.

Voice Alarm applications
Voice alarm loudspeakers are specifically designed for use in buildings where system performance for verbal evacuation announcements is governed by regulations.

The LC1-UM06E8 Modular Ceiling Loudspeaker is designed for use in voice alarm systems and is EN 54-24 certified and compliant with British standard BS 5839-8.

The loudspeakers have built-in protection to ensure that fire damage to the loudspeakers does not cause failure of the connected circuit. In this way system integrity is maintained, ensuring loudspeakers in other areas can still be used to inform people of the situation.

The loudspeakers can also be used in combination with a metal fire-dome to increase protection of the cable termination.

The loudspeakers have a ceramic screw-terminal connection block, thermal fuse and heat-resistant, high-temperature wiring.
