Voice Alarm applications
Voice alarm loudspeakers are specifically designed for use in buildings where system performance for verbal evacuation announcements is governed by regulations. The LC1 Modular Ceiling Loudspeaker range is designed for use in voice alarm systems and is compliant with British standard BS 5839-8
The loudspeakers have built-in protection to ensure that fire damage to the loudspeakers 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 loudspeakers can also be used in combination with a metal fire-dome to increase protection of the cable termination
The loudspeakers have a ceramic screw-terminal connection block, thermal fuse and heat-resistant, high temperature wiring
Certifications & Approvals
All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 68-5 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. All plastic parts are self extinguishing according to UL 94 V0
