Output Signals (Redundant System)
Audible Alarm & Power Fail Signal
The Audible alarm and Power Fail signal are available from the signal card located on the backplane. The
audible alarm is silent and the Power Fail signal is "High" when all power modules are functioning properly.
The audible alarm will sound and the Power Fail signal will be "Low" under the following conditions :
a. One of the power supply modules is not functioning and is still attached to the backplane.
b. One of the power supply modules is attached to the backplane without an AC power cord plugged in.
Removing the not functioning power module from the backplane or pushing the reset switch provided will
reset the audible alarm and also the Power Fail signal.
