If a PSU is not fitted, the corresponding LED will not illuminate unless the incorrect number
of PSUs are selected when it will flash red.
The Comms LED indicates external communication with the frame. On a passive panel this
will mean communication from the frame or an active control panel. On an active panel this
will be communication with Statesman via an RS422 link or via Ethernet.
