If your Caddx alarm panel keypad beeping and having Fire/Smoke alarms that might be due to a fake alarm (meaning a fire alarm occurred but not present now) or worse there might be a real fire! For this reason move around and search for fire! If you find a real fire, call immediately Fire Department. If there is no real fire, follow the steps to reset Caddx fire alarms.

How to Reset Fire Alarm ?

  1. (optional) Press UP key in your alarm keypad. This shows “open/busy” zone numbers in your caddx alarm panel. Open your zone list and find “open/busy” zones there. It’s a good idea to double-check that ” open/busy” zones physically.
  2. If you are sure that there is really no Fire, you may reset SMOKE (Fire detector) zones now. In order to do that, enter *7 at caddx keypad. This will reset fire alarms in ALL of SMOKE detectors and your alarms will be cleared.
  3. Now re-press UP key in your alarm keypad. You should not see any “open/busy” SMOKE zones. (Maybe you may see open PIR detector zones, in which you or other people detected but this is not important)

When you press *7 to reset SMOKE detectors, Caddx alarm “cuts” DC voltage at SMOKE+ port. For this reason you don’t need to repeat this in all of partitions. One reset from any partitions is enough.

Notice that this only works if your Fire/SMOKE detectors getting 12V DC voltage from SMOKE+ port. If they get (+12V) voltage from AUX+ port, even if you press *7, nothing changes. In this case call for support service for maintenance.

Another reason of not clearing caddx fire alarms with *7 might be a wire problem or 3.3K-ohms resistance problem. All zones in Caddx alarm check for ” 3.3K-ohms ” resistance. If that resistance not “found” (by any means, including wire problem, bad 3.3K-ohms resistance) you can not clear that zone alarm. Only thing you can do is BYPASS that zone temporarily and call service for wire/resistance problem.
