Connection of relay outputs to B7-CPB11
The X5 connector plug on the B7-CPB11 main control unit has 3 freely programmable bistable 240 V/3 A relay contacts for
actuating sirens, permanent magnets, relays, etc. With planning software you can define whether the contact is a working
contact or normally closed contact. By programming an “Active in fail-safe position”, the state of each individual relay can be
defined for power supply failure or shut down of the control panel.
