The 6W white LHM 0606/00 Ceiling Loudspeaker from Bosch is screw mounted into the ceiling. The LBC 3080/01 fire dome is sold separately. This full range loudspeaker is suitable for both speech and music reproduction in shops, department stores, schools, offices, sports halls, hotels, and restaurants.
The speaker assembly consists of a single-piece, 6W dual cone loudspeaker and frame, with a 100 V, matching transformer mounted on the back. A circular metal grille is an integrated part of the front. The appearance and neutral white color has been selected to be unobtrusive in virtually all interiors.
The mounting assembly is simply and quickly installed into a hole in the ceiling cavity. It is secured with the included 3 white screws. The 3 wires on the matching transformer (primary) provide for selection of nominal full-power, half-power, or quarter-power radiation. A circular template for marking a 6.49” (165.00mm) diameter hole is included with the loudspeaker.
During a fire, the ceiling cavity in which loudspeakers are installed can allow flames to spread throughout a building. To prevent fire entering the caving via the loudspeaker, the ceiling loudspeaker can be fitted with a protective steel fire dome (LBC 3080/01). This fire dome (sold separately) is mounted on the loudspeaker assembly using 4 self-tapping screws, supplied as standard. There are 4 knock-out holes; 2 for rubber grommets (supplied) and 2 for cable glands.
