Communications Systems | LBC 3430/02 Bidirectional Sound Projector LBC 3430/02 Bidirectional Sound Projector www.boschsecurity.com u Excellent speech and music reproduction u Ceiling and/or wall mounting u Robust aluminum extrusion enclosure u Water and dust protected to IP 55 u BS 5839‑8 and EN 60849 compliant The LBC 3430/02 is a 12 W bidirectional sound The sound projector is constructed from extruded projector intended for speech and music reproduction aluminum and finished in off- white. The front-grills in indoor and outdoor applications. The two and bracket are made from aluminum to increase loudspeakers facing in opposite directions are ideally corrosion resistance. suited to applications such as subway tunnels, long corridors and shopping arcades. The sturdy, aluminum Certifications and Approvals enclosure is finished in the color off-white. The sound Quality assurance projector is suitable for use in voice alarm systems. All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in Functions accordance with IEC 268-5 Power Handling Capacity Voice alarm loudspeakers are specifically designed for (PHC) standards. Bosch has also developed the use in buildings where performance of systems for Simulated Acoustical Feedback Exposure (SAFE) test verbal communication announcements is governed by to demonstrate that they can withstand two times regulations. The LBC 3430/02 is designed for use in their rated power for short durations. This ensures voice alarm systems and is compliant with British improved reliability under extreme conditions, leading Standard BS 5839‑8 and EN 60849. to higher customer satisfaction, longer operating life, The loudspeaker has built-in protection to secure that, and lessons the chance of failure or performance in the event of a fire; damage to the loudspeaker does deterioration. not result in failure of the circuit to which it is Safety acc. to EN 60065 connected. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used Emergency acc. to BS 5839‑8 / EN 60849 to inform people of the situation. The loudspeaker has a ceramic terminal block, thermal fuse and heat Water and dust protection acc. to IEC 60529, IP 55 resistant, high-temperature wiring.
