This monitor board is used to monitor the integrity of the speaker circuit. It can monitor the state of the speaker circuit and all its branches together with the LBB 4440/00 monitor control panel. The state of the speaker line is transmitted to LBB 4440/00 through the existing speaker cable. Basic function this monitor board is installed in the housing of the last speaker in the speaker circuit or packaged in a separate housing. It can monitor branch lines. If a speaker circuit has multiple branches, a separate LBB 4443/00 is installed for the last loudspeaker in each branch. This monitor board can detect and report circuit faults within 100 seconds.
