The LHM 0606/00-US is a general-purpose, 6 W, cost-effective ceiling loudspeaker. It is screw mounted into the ceiling. An optional fire dome is available.

Functions
An economic flush 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 70-volt matching transformer mounted on the back. A circular metal grille is an integrated part of the front. The appearance and neutral white color have 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 continuous 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 improved reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and lessens the chance of failure or performance deterioration.

Safety according to EN 60065

Installation/Configuration Notes

Mounting
The assembly is simply and quickly installed into a hole in the ceiling cavity and secured with the three white screws (supplied). A circular template for marking a 165 mm (6.5 in) 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 the building. To prevent fire entering the cavity via the 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 knockout holes; two (2) for rubber grommets (supplied) and two (2) for cable glands (PG13).
