Functions
-
The LBB1992/00 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
