1.7 P3W Coordinator Connections
A connector is located in the bottom of the (PS721) wireless option module to connect to the P3W
coordinator (PS722). The connection between these should be made using a shielded network cable
with 3 pairs of wires – each pair to be twisted. Suitable cable conforms to the specification for RS-422
networks. This cable can be up to 200m long so that the P3W coordinator may be mounted, for
example, on the roof of the building containing the master station.
The Communications cable and appropriate glands for the P3W coordinator will need to be sourced
locally, according to site requirements. Connect the Communications cable as shown below, noting
that the connections are NOT all one to one.
