Diagnostic depth
The output signals from the two blocking switches which prevent remote panel activation have been implausible in relation to each other. One signal has indicated a deactivated remote panel and the other an activated remote panel.
Only one of coordinator pins 52 and 53 have been earthed. Both must be earthed at the same time.If the fault occurs when the remote panel is deactivated, this indicates an open circuit in one of the blocking switch circuits. If the fault occurs when the remote panel is activated, this indicates an short circuit to earth in one of the blocking switch circuits.
