Wiring Connections:
The power and communications wires for the sensor are connected to a plug that
is attached to the head of the sensor. The wires will already be attached to this
plug at SSi, however for reference the wiring for this plug is:
Sensor Plug Terminal #1: Green Wire (to location #1291 on terminal strip)
Sensor Plug Terminal #2: White Wire (to location #1281 on terminal strip)
Sensor Plug Terminal #3: Red Wire (to location #1261 on terminal strip)
Sensor Plug Terminal #4: Black Wire (to location #1271 on terminal strip)
20 feet of sensor wire is included with the unit, however it is capable of operating
over substantially longer distances if required. When attaching the necessary
wires to the terminal strip inside the panel, all connections should be made
according to the following diagram:
