• Robust aluminum extrusion enclosure
• Water and dust protected to IP 55
• EN 54‑24 certified
The LBC 3430/03 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 white. It has provisions for cable loop-through connection and inside mounting of a line- or loudspeaker- supervision board. The sound projector is suitable for use in voice alarm systems.
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 3430/03 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. The sound projector is constructed from extruded aluminum and finished in white. The front-grills and bracket are made from aluminum to increase corrosion resistance.
Installation/configuration notes
Mounting
The sound projector can be mounted to the ceiling or wall by means of two screws. The connection cable is fed out through an ABS cable gland (PG13.5) in the base of the mounting bracket. The wires can be terminated on the inside ceramic screw terminal block. For loop‑through connection, the cover plate is fitted with a second hole (covered as standard supplied).
Power Setting
The loudspeaker includes a transformer for both 70 V and 100 V with taps on the primary winding for different power settings. The required power radiation (in 3 dB steps) can easily be selected via a rotary vari‑tap switch, located close to the screw terminal block. The sound projector has an provision for inside mounting of the optional line-/loudspeaker supervision board.
