Bosch LBC-3481/12 15W HORN SPEAKER in Dhaka

Product description:

The LBC 3481/12 is a circular 10 W horn loudspeaker, measuring 156 mm (6.14 in) in diameter. They are made from aluminum. The edges of the horns are covered with a PVC profile for protection against impact damage. They are light grey (RAL 7035), and are water and dust protected.

The LBC 3481/12 has built-in protection to ensure 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 Horn loudspeaker has a ceramic terminal block, thermal fuse and heat resistant, high-temperature wiring. They have provision for inside mounting the optional line/ loudspeaker supervision boards.

The LBC 3481/12 is designed for use in voice alarm systems and is compliant with EVAC standards.
