Bosch LS1-OC100E1 Hemi-directional loudspeaker is an easy to install, innovative loudspeaker which projects consistent and high quality sound, ensuring superb reproduction of background music and high speech intelligibility for paging or emergency calls. The speaker?s opening angle and high sound pressure level allows it to cover at least 600 m2, making it extremely suitable for indoor high-ceiling areas like warehouses, transport and exhibition halls, mega stores and swimming pools.

The Bosch LS1?OC100E1 is used in voice alarm systems and is compliant with EVAC standards. The loudspeaker has built-in protection to ensure that a fire-damaged loudspeaker does not cause failure of the connected circuit.

The loudspeaker has ceramic terminal blocks, a thermal fuse and heat-resistant, high-temperature wiring.

The loudspeaker is made of high-impact ABS TSG, selfextinguishing according to class UL 94 V 0 and with?the highest flame retardant rating (UL 94 5VA). The?loudspeaker has a white and silver finish; the metal?grille has a silver finish.
