Connection of monitored inputs and outputs
The X10 connector plug on the B6-BCB13 and B6-BCB12 main control units is for connecting the transmission unit (main
detector) and alarm unit (sirens) for loads between 16
Ω and 1 kΩ. The interface includes two 1.5 A control outputs moni-
tored for short-circuit and wire breakage and two monitored inputs. The OM1 output has a feedback input for external trigger
confirmation.
Notice
Due to the fusing of the internal peripheral voltage (27 V) with quick-action 4 A, the maximum total output cur-
rent of all simultaneously actuated monitored outputs must not exceed a continuous current of 4 A per control
panel.
