The LHM 0606/xx is a general purpose, 6 W, costeffective ceiling loudspeaker. The /00 version is screw mounted and the /10 version is clamp mounted into the ceiling. An optional fire dome LBC 3080/01 is available.
Functions
An economic flushing-mounting ceiling loudspeaker is available for general purpose applications. 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.
Certifications and approvals
All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 268-5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test
to demonstrate that they can withstand two times their rated power for short durations. This ensures extra reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and much less chance of failure or performance deterioration.

Installation/configuration notes
Mounting
The assembly is simply and quickly installed into a hole in the ceiling cavity. The /00 version is secured with the three white screws (supplied). The /10 version is secured by two integral spring-loaded ceiling locking clamps. A circular template for marking a
165 mm diameter hole is included with the loudspeaker.
Three wires on the matching transformer (primary) provide for selection of nominal full-power, half-power or quarter-power radiation.
Fire dome
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
2 | LHM 0606/xx Ceiling Loudspeaker
loudspeaker, the ceiling loudspeaker can be fitted with a protective steel fire dome (LBC 3080/01). This optional fire dome is mounted on the loudspeaker assembly using four self-tapping screws, supplied as standard. There are four knock-out holes; two (2) for rubber grommets (supplied) and two (2) for cable glands. (PG13).
