6.9 Fault Relay Alarm
The Fault Relay Alarm function provides Power Failure and Port Link Down/Broken detection. With both power input 1 and power input 2 installed and the check boxes of power 1/power 2 ticked, the FAULT LED indicator will then light up if either power failure occurs. As for the Port Link Down/Broken detection, the FAULT LED indicator will light up when the port failure occurs; the check box beside the port must be ticked first.
Please refer to the section, ‘Wiring the Fault Alarm Contact’, for the failure detection.
Power Failure: Tick the check box to enable the function of lighting up the FAULT LED on the panel when power fails.
Port Link Down/Broken: Tick the check box to enable the function of lighting up FAULT LED on the panel when Ports’ states are link down or broken.
