Description

Product details of BOSCH LBB 1992/00 Plena Voice Alarm Router Price in BD for PA System Supplier Price BD

The LBB 1992/00 has a set of relays for zone-switching the power amplifier output(s) to different loudspeaker groups. Each zone can be switched between:

• The call channel (call-station selection, all-call microphone, or emergency activation)

• The BGM channel (front panel selection)

• Off

Volume override relay contacts are provided for each zone separately for overriding local loudspeaker volume controls. This ensures that priority messages go through with a given volume, even though the local volume controls may be set to a low volume level for background music, for example. Both three-wire and four-wire override schemes are supported. A call or a triggered input will activate these contacts for the appropriate zones, together with an additional voltage free contact (call-active) for control purposes. An overload protected 24 VDC output provides power for driving external relays, making an external power supply unnecessary. The master output channel, or one of the input channels, can be selected to be monitored with headphone connector and LED meter.
