What to do if the ARM light is slowly blinking and the LCD KP shows COMM FAILURE on my FBII Security System?
- C
  Courtney PowersAug 7, 2025
  If the ARM light is slowly blinking and the LCD KP displays 'COMM FAILURE', it indicates a failure to communicate with the central station. First, check for any cut or disconnected telephone lines and repair them if needed. Then, verify the panel programming for any incorrect central station information and reprogram it with the correct details if necessary. If the issue persists, it might be due to faulty telephone lines, in which case you should consult your local telephone company. As a last resort, the panel itself might be faulty and need replacement.

  If the AC/LB light is off, it could be due to a primary AC power outage. Check the transformer connection and the AC input voltage. Alternatively, the keypad might be faulty, requiring replacement.

What to do if the Siren/Speaker does not sound in my FBII OMNI-400 EU Security System?

  If the siren or speaker isn't working, first test the siren/speaker by connecting it directly to a 12VDC power source. If no sound is produced, replace the siren/speaker. Next, inspect the wiring for any open or short circuits, and replace the wiring if necessary. Finally, check terminals 3 (+) and 4 (-) for 12VDC when the panel is in alarm (if programmed for bell output); if no voltage is measured, the panel might be faulty and need replacement.

How to fix ZONE light ON & READY light OFF issue in FBII Security System?

  Jonathan WolfAug 22, 2025
  If the ZONE light is ON and the READY light is OFF, it means a zone is faulted and the system isn't ready. Inspect the loop wiring for any opens or shorts and repair them. Also, check the EOL resistor for any opens or incorrect values. Another possible cause is a faulty keypad that needs to be replaced. As a final check, verify the zone terminal voltage for 3.3VDC; you can also temporarily bypass the zone to test; if the problem persists, replace the panel.

How to troubleshoot AC/LB light slowly blinking with LCD KP showing LOW BAT on FBII OMNI-400 EU?
- B
  Brandy KingAug 27, 2025
  If the AC/LB light is slowly blinking and the LCD KP displays 'LOW BAT', it indicates a DC power issue or low battery voltage. Check the battery connections and the battery voltage with the transformer disconnected. If the voltage is less than 11VDC, let the battery charge or replace it.

How to fix a keypad display that is not lit on my FBII OMNI-400 EU?

  If the keypad display is not lit, it could be due to a loss of both AC and DC power. Check the transformer and battery connections, and verify the AC input and battery voltage with the transformer disconnected. Another potential cause is that the keypad isn't receiving power. In this case, check terminals 20 (+) and 17 (-) for 12VDC.
