Connection of monitored inputs and outputs
The X10 connector plug on the B7-CPB11 main control unit is for connecting the transmission unit (main detector) and alarm
unit (sirens) for loads between 16
Ω
and 1 k
Ω
. The interface includes two 1.5 A control outputs monitored for short-circuit and
wire breakage and 2 monitored inputs. The OM1 output has a feedback input for external trigger confirmation.
