The 6W white LB1-UM06E-1 Metal Cabinet Loudspeaker from Bosch is a circular metal cabinet emergency loudspeaker that delivers professional performance from a robust, yet aesthetically designed metal enclosure. It is a suitable loudspeaker for indoor use in offices, schools, car parks, shopping centers, and in areas where vandalism is a potential hazard.

The cabinet is designed for both surface and recessed mounting on walls. The back box provides a selection of mounting holes, even for mounting on U40 and MK installation boxes. The back box has 2 knockout holes on the topside for 2 cable glands (sold separately) for loop-through connection.

For extra installation convenience, a safety cord from the back box lets the installer temporarily hang the front grille unit during installation. The cabinet has a three-way terminal block with screw connections suitable for loop-through wiring (including earth). The 4 primary taps on the matching transformer allows selection of nominal full-power, half-power, quarter-power, or eighth power radiation (in 3 dB steps).

Voice Alarm
Voice alarm loudspeakers are specifically designed for use in buildings, where the performance of PA systems is subject to official regulations. It is designed for voice alarm systems, and is compliant with British Standard BS 5839-8 and EN 60849.
The loudspeaker has built-in protection to ensure that in the event of a fire damage 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.
Connections and Safety
The loudspeaker has a ceramic terminal block, thermal fuse, and heat-resistant, high-temperature wiring. The cabinet has a provision for internally mounting the line/loudspeaker supervision board (sold separately).
