If your home alarm keeps beeping for no apparent reason, it’s usually due to a “trouble” condition.
You may already know that there are many reasons for alarm system keypads to beep. Some keypad sounds are part of normal operation, like button press chirps or the built-in “Chime” feature. (To find out how to turn the chime on or off, see the links for user manuals further down the page.)
During a trouble condition, the intermittent, annoying beeping is intended to make you come to the keypad where you can see the display. Lights or a text readout can then give you further information about the problem condition.
Sometimes the problem isn’t your security system keypad at all. It’s often hard to tell exactly where a chirping or beeping sound is actually coming from.
A smoke alarm chirping can be very hard to locate. If you suspect this is the problem, see this page on how to stop a beeping smoke alarm.
If you’re sure it’s your home security alarm chirping, read on to see how to stop it and figure out the problem.
See this page if your DSC home alarm is beeping.

If your system is "out of control" and won't respond to keypad codes or commands, you may want to shut it down until you can schedule service. See this page on "How to Disable the Alarm System in Your Home".
If you have a valid code for the system, try using it to arm, then disarm the system.
If the alarm keeps beeping anyway, continue with the following steps.
On many systems, the “*” or “#” key will stop the keypad sounder.
Press any key that may be labeled “Reset”, “Clear”, "Cancel", or something
similar. Some panels may require additional keystrokes to permanently
stop the beeps, but this alone will work for some.
Also, be sure to try pressing the button momentarily as well as pressing and holding for a few seconds.
For most Radionics systems, pressing “Command”, then “4” will silence the keypads. “Command, 4, 0” will display what caused the trouble condition. For alphanumeric keypads you can read the trouble as text; for LED keypads, you’ll need a user manual to decode the light pattern.
Remember that silencing the keypad will not disable beeping permanently. After a while, the noise will come back. As long as the initial cause of trouble remains, the alarm keeps beeping until it’s fixed.
easily operate any alarm system, you’ll need a user manual. This in turn
requires that you know your security panel make and model number.
Most alarm manufacturers supply a decal inside the main panel box showing brand, model, and a wiring diagram.
After you find your brand and model information, you can download a user manual from one of the links above. If you’re a do-it-yourselfer or an alarm installer, you can also find programming manuals for many of the panels listed.
Most user manuals will have instructions on how to read trouble
codes directly from the keypad. For most brands of security panel, you
can enter a few keystrokes to bring up an LED or alpha/text display of
the specific source of the problem.
Common problems include battery trouble, loss of AC power, and phone line connection problems. If you have any wireless security equipment, a low battery in one of these devices could also be at fault.
Depending on the cause, most manuals suggest actions you can take to resolve the issues. Some of these you can do easily, such as checking circuit breakers or changing a battery. Other problems may require the attention of an alarm technician.
