The battery may need to be replaced. An alarm will chirp every 30 to 60 seconds for a minimum of seven days. With a "low battery" announcement, disconnect the unit and replace the batteries. You can also put a unit into low battery hush for up to 12 hours on newer units by pressing the test/hush button.
Take out its battery, then press the ``Test'' button holding it down for 15 seconds. An alarm will sound for a short time, then the alarm will silence.
Clear Residual Charge to Stop the Chirp
Remove the alarm from your ceiling or wall. Open the cover and take out the battery. Press and hold the test button for 15-30 seconds. This will fully reset the smoke alarm and drain any charge left inside.
The basic instruction for temporarily silencing your alarm system is to press the silence or hush button, which will deactivate the triggers for a few minutes. Most smoke detectors have this button named 'test,' which you can press and hold for a few seconds to get the job done.
Low battery
Smoke detectors are designed to go off when their electrical current goes down. This is because smoke in the air will reduce the electrical current. If your battery is low, the current will be low, meaning you get a false alarm.
Turn the power supply off at the source and completely power down the system. Then, wait up to a minute to turn it back on. A common cause of beeping is low batteries. If any component of your system operates on batteries, replace them and then reset the alarm to allow the system to register the new batteries.
In most cases, you can find the 'hush' button on the smoke detector's cover.
The battery may need to be replaced. An alarm will chirp every 30 to 60 seconds for a minimum of seven days. With a "low battery" announcement, disconnect the unit and replace the batteries. You can also put a unit into low battery hush for up to 12 hours on newer units by pressing the test/hush button.
You can silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
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.
Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping.
Take the individual chirping unit down: After shutting off the circuit breaker, take the individual unit down, remove the battery backup (if it has one), then hold the test button down for 15 seconds. This should reset your alarm and stop the chirping.
Smoke detectors chirp to indicate a low battery. This chirping happens every 30 to 60 seconds for at least seven days.
Most systems will begin beeping or chirping as a result of a total power outage or failure to recharge the system backup battery. 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.
The beeping sound the low battery alarm makes can become very annoying but can be disconnected by removing the drained battery from your home alarm system panel. Make sure to replace the drained battery with a new one to keep your home alarm system functioning properly.
Many alarm systems will beep when the battery power is low. You may hear a beep every few hours or once a day when the system runs its automatic battery test.
When the evening temps drop during the winter months, the slight drop in voltage may be enough to trigger the smoke detector's low battery alarm in the cold of night. Hardwired systems also have a backup battery, so the smoke detector still works in the event of a power outage.
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.
While your smoke alarm sounds, pressing the hush button will silence the smoke alarm for approximately 10 minutes. The hush feature is typically used where an alarm has been triggered accidently. This provides time to clear the current environment of fumes that triggered the alarm without the alert tone sounding.
