2.2 Electrical connections
The KSGD connections are located on the rear of the detector PCB.
The KSGD will operate from a 12/24 volt AC or DC supply. Start-up current from a 24 volt AC supply
is 260mA with steady state of 100mA. A single plug on the PCB accepts all the electrical connections.
A small flat bladed screwdriver can be used to prise the plug away from the socket.
