For many of our most popular systems, beeping alarms and low battery trouble beeps can be silenced by pressing the [OFF] or [#] buttons from the keypad.
You can press the Test/Silence button to silence the alarm. For Smoke alarms, the ADT Base LED ring blinks red and the number pad disappears.
Remove the alarm from its mounting base. Press and release the reset button twice. Press and hold the button for 5 seconds until the red LED starts blinking quickly.
Stopping a smoke alarm from beeping is often simple. Get a step ladder and carefully reach for the alarm. Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping. If this doesn't work, grasp the device and turn it counterclockwise.
Disarm the alarm system
The process for doing this differs for each system, but one of the following is usually recommended: Enter the passcode and disarm. Arm the system, and then disarm it, immediately. Press the status button on the keypad.
Dust and debris can easily accumulate inside your hard-wired smoke alarm, causing that incessant chirping sound. This build-up can interfere with the sensing chamber, triggering false alarms. To prevent this, make a habit of cleaning your smoke detectors regularly.

A Checklist for Stopping the Chirping
First, replace the old battery. If you've installed a new battery and the alarm continues to beep, drain any residual charge from the unit. Remove the unit from the ceiling and remove its battery, then hold the test button for 15 seconds. Next, replace the battery.
Press the hush/silencing button. It will silence the entire interconnected system. The button may also say “test.” It should silence all the alarms immediately unless there's still smoke and debris. It will reset in eight minutes, given that the smoke and debris have dissipated.
This chirping happens every 30 to 60 seconds for at least seven days. When you hear this, it means the battery needs replacing.
If you replaced the battery and it's still beeping, the smoke detector might have expired like milk. Smoke detectors have an expiration date. The sensitive equipment inside can only work reliably for so long, so if yours is beeping and its expiration date has passed (or will in a year or two), it's time to replace it.
