ABT-xCtrLine-4 provides 4 independent loudspeaker line outputs (A, B, C, D). The board allows switching between the main and backup amplifiers.
It is installed in the available slots of the SMART-CU-11LCD, SMART-CU-11LT or SMART-CU-8LCD control units.
Line measurement methods can be performed by: Impedance, Loop or End of Line (EOL) Module. The measurement method is selected from the software configuration.
The ABT-xCtrLine-4 enables the detection of open and ground leakage faults.
