Smoke Alarm Press the recessed test switch to silence the smoke detector sounder for 5 minutes. If necessary, silence the alarm 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.
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. It should detach from the base so you can open the battery compartment in the back. Remove and replace the battery to see if it caused the issue.
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.
First, try the reset button on each smoke alarm. If that doesn't work, flip the circuit breaker off and on. If that fails, you may have to disconnect the smoke alarms and remove the backup batteries inside them one by one. (The batteries are there to protect you during a power outage.)
A hard-wired smoke detector usually chirps for one of three reasons: A dead battery. Dust inside your smoke detector. An old or malfunctioning detector.
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.
Will a smoke alarm eventually stop chirping? A smoke alarm will eventually stop chirping if it stops detecting smoke or if the condition that created the false alarm is fixed. For example, if dust and debris is causing your alarm to sound, cleaning it will stop it from chirping.
To disarm the system, enter your user code then press the [OFF] key. will also be sent. To stop the alarm sounding, simply disarm the system.
The first sign of alarm battery failure is usually a beeping keypad. The beeping or chirping will often occur at the same time. This is because many panels do their automatic battery test every 24 hours. Less commonly, a low battery condition can cause false alarms at random times throughout the day.
There is a Reset button located behind the bottom panel of the ADT Base and a momentary press of this button will cause the ADT Base to reboot.
Several common causes can explain why your hard-wired smoke detector is beeping: Low battery: Even hard-wired smoke alarms have backup batteries that need replacing periodically. A low battery can cause that annoying beeping sound. Dust buildup: Dust and debris inside the smoke detector can trigger false alarms.
In most cases, you can find the 'hush' button on the smoke detector's cover.
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.
For hardwired smoke detectors, random beeping may result from electrical interference, loose connections, or power fluctuations. Wireless devices, such as Wi-Fi routers or baby monitors, can also disrupt the detector's signal, causing unexpected beeping.
Hardwired smoke detectors can still beep even if there is no battery. Possibly the backup battery might have been activated and that can signal a problem. The backup battery may have run out and that is causing your hardwired smoke detector to chirp.
Common causes of alarm system beeping can include: the alarm has been activated and the siren has timed out - check for signs of a break-in. low backup battery issues - check the backup battery and replace it if needed - more info on replacing the alarm backup battery.
To get your smoke alarm to stop chirping if you've already changed the battery, first try draining any residual charge by holding the test button down for 15 seconds. If this doesn't solve the problem, clean the unit. A blast of compressed air will often remove the dust particles that are causing the beeps.
If your smoke detector is hardwired, pull out the cable attaching it to the wall or ceiling and remove any backup batteries. If your alarm is an independent unit, simply remove its batteries. In some alarms, the batteries may be hidden behind a sliding or screw-mounted panel.
