16.9 How to Exercise the Output Relays
To test the Relay output channels by forcing the relays to a specific state:
1. Login as an Engineer. Navigate to the Outputs screen:
c) From the System Status screen select the Inputs icon:
d) Toggle the Inputs Icon to select the Outputs icon:
2. Select the channel to be tested, and then select Force or Force Deactivate, as required. The channel will indicate a
Fault until the action is cancelled.
3. When ready, select the channel again, and select Clear Force from the popup menu.
4. Repeat steps 4 and 5 for all relay output channels.
Note: The system will indicate a fault and the System Fault relay will open while a Force condition is present.
To avoid any unwanted activation of output devices (e.g. emergency flooding) always inhibit or disable relay
activated outputs before exercising the relays and remember to enable them when testing is finished.
Check and ensure that the system is restored to normal operation once all testing is finished.
