If there's a low battery warning, you might need to replace the alarm system's battery. If the alarm persists after replacing the battery, consider power cycling the entire alarm system. Turn off the main power supply to the alarm, wait a few minutes, and then turn it back on.
To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds.
You can silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Low batteries normally don't cause false alarms, but sometime cause trouble notifications. However, if your system has a heavy power draw, a power failure and low-battery combination can sometimes cause too low a voltage to a powered sensor (eg a PIR) which can make it super-touchy and cause a false alarm.
If there's a low battery warning, you might need to replace the alarm system's battery. If the alarm persists after replacing the battery, consider power cycling the entire alarm system. Turn off the main power supply to the alarm, wait a few minutes, and then turn it back on.
Go to your main control box and disconnect the battery supply, which will stop all beeping and shut your alarm system down. Once power is restored, you can reconnect your battery and your alarm system should work as before.
'Low battery chirp' is a short high pitched warning sounds emitted by your smoke alarm every 30-40 seconds. Pressing the 'Hush' button will force the alarm into 'low battery hush' mode, temporarily silencing the low battery warning for 8 hours, to give you time to replace the 9V 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.
Most alarms have a red reset button. Hold this down for 15 to 20 seconds and see if that doesn't do the trick. Method 2 - Try a manual reset. Remove the batteries and hold down the reset button for 15 to 20 seconds.
All First Alert Alarms come with a Test Button. With the battery removed from the unit, press and hold this button for 30 seconds. This will fully reset the alarm, removing the residual charge of the previous battery.
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.
Smoke detectors have a built-in residual charge, even with the battery removed. Press down and hold the test or reset button for a minute or so, this should drain it and shut it up.
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.
The process for stopping a smoke alarm is simple. For battery-operated smoke alarms, this can be as simple as pressing the “test” or “silence” button. If your smoke alarms are interconnected, you may need to flip the “smoke” switch on your breaker box.
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.
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.
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.
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.
It sounds like the battery in your main panel needs to be replaced. The battery is located in the main panel box of your system. This box is typically found in a utility room, closet or attic.
