6.9 Fault Relay Alarm
The Fault Relay Alarm function provides the 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 be possible to light up when
any one of the power failures occurs. As for the Port Link Down/Broken detection, the
FAULT LED indicator will light up when the port failure occurs; certainly the check box
beside the port must be ticked first. Please refer to the segment of ‘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.
