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.
