The LBC 3430/02 is a 12 W bidirectional sound  
projector intended for speech and music reproduction  
in indoor and outdoor applications. The two  
loudspeakers facing in opposite directions are ideally  
suited to applications such as subway tunnels, long  
corridors and shopping arcades. The sturdy, aluminum  
enclosure is finished in the color off-white. The sound  
projector is suitable for use in voice alarm systems.  
The sound projector is constructed from extruded  
aluminum and finished in off- white. The front-grills  
and bracket are made from aluminum to increase  
corrosion resistance.  
Certifications and approvals  
Quality assurance  
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. 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 lessons the chance of failure or performance  
deterioration.  
Functions  
Voice alarm loudspeakers are specifically designed for  
use in buildings where performance of systems for  
verbal communication announcements is governed by  
regulations. The LBC 3430/02 is designed for use in  
voice alarm systems and is compliant with British  
Standard BS 5839‑8 and EN 60849.  
The loudspeaker has built-in protection to secure that,  
in the event of a fire; damage to the loudspeaker does  
not result in failure of the circuit to which it is  
connected. In this way, system integrity is maintained;  
ensuring loudspeakers in other areas can still be used  
to inform people of the situation. The loudspeaker has  
a ceramic terminal block, thermal fuse and heat  
resistant, high-temperature wiring.
