Once both the “A” and the “B” input power LEDs are green, other LEDs can be used to
diagnose other faults.
One fault that may show as a red flashing ALM LED on the alarm card is communications fail.

If there is no controller present, the flashing red LED can be addressed by switching the Tens and Units
rotary switches to positions 0 using a small Phillips screwdriver. If a controller is present the signal
between the alarm card and the controller is likely broken. Please examine all wiring. Also note: all
shelves in a system must have different addresses to be recognized by the controller.
