If your ADT security system shows “FC”, then it is not communicating properly. “FC” stands for “Comm Failure” and is a common problem in the ADT security system. Fortunately, such minor issues do not require contacting ADT. By following a few basic steps (outlined below), you should be able to troubleshoot and resolve them yourself.

In this particular case, the FC code must be reset. This can usually be done by entering your code followed by the number “5”.

If all else fails, remember that you can contact your local ADT customer service representative for assistance.

They are experts and can help you solve any problem. However, in most cases, you can reset the FC code by following these three steps:

• Step 1: Locate the reset button on the ADT alarm keypad. Press the reset button and hold it for about two seconds.
• Step 2: Sometimes the reset button doesn’t work. If that doesn’t work, you’ll have to use Plan B. If you’re sticking with Plan B, press the “*” button, then “7” and finally “2.”
• Step 3: If you have followed steps 1 and 2 correctly, your alarm system will reset and then turn off.

Why is ADT Comm Failure or FC happening on my security system? If the Comm Failure message does not disappear after a few minutes

1. Contact your security organization and let them know that you have a Comm Failure message on your keyboard.
2. Ask the security company to put your account in test mode so that the police are not sent.
3. Turn on your security system in away or stay mode.
4. Wait 60 seconds for the exit delay to expire and for the keypad to display “system armed”.
5. Open the door or window and wait for the siren to sound.
6. After the siren sounds, turn off the alarm system as usual by entering your user code and turning it off.
7. Disarm the security system a second time to reset the alarm message displayed on the keypad.
8. Wait 2-3 minutes for the alarm system to send a signal to the central station.
9. The Comm Failure message should now be removed.

If the Comm Failure message still does not clear, your system may be programmed with a dialing delay that requires the siren to sound for at least 30 seconds before the alarm system sends a signal.

Turn the system back on and repeat steps 3-6, but this time wait 30-40 seconds before turning off the alarm system.

If the Comm Failure persists, then you’ve done almost everything you can, and it’s time to call the burglar alarm service for help.

Comm Failure can occur for several other reasons. Why is ADT Comm Failure or FC happening on my security system?

Make a local call

The most current reason is that all alarm panels must now dial the area code to make a local call.

The Federal Communications Commission (FCC) recently designated 988 as the new national suicide prevention hotline number.

Because of this, all calls, including local phone calls, must be preceded by the area code.

When your alarm system calls your security organization, it dials the phone number programmed into the alarm system’s control panel.

Without an area code, a call to the monitoring center is not possible. The alarm system will try to call several times and display a Comm Failure message if the call fails.

You will need to contact your security company and ask them to come to your home to reprogram your phone number to fix this issue.
