The Bosch LC1-WM06E8 4 inch In-Ceiling Loudspeaker can be used for a wide variety of ceiling environments. This 6 W single cone loudspeaker provides excellent speech and music in indoor public address applications. The 4" Ceiling loudspeaker is suitable for use in air‑handling spaces when installed with the LC1‑MFD enclosure. The loudspeaker frame includes provision for mounting the optional pilot-tone indication board or WLS board and has a light conductor to indicate the pilot-tone status.

The Bosch LC1 Modular Ceiling Loudspeakers are designed for use in voice alarm systems and are EN 54‑24 certified. The loudspeakers have built-in protection to ensure that fire damage to the loudspeaker 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 LC1 loudspeakers can also be used in combination with a metal fire-dome to increase protection of the cable termination. They have a ceramic screw-terminal connection block, thermal fuse and heat-resistant, high-temperature wiring.

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.
