Usually, if your smoke detector squeaks, then your battery has failed. The chime is a built-in warning system to let you know to change the battery. While this is the most frequent cause, there can be other reasons for the constant chirping.
All homes typically have two types of smoke alarms: battery-powered or hard-wired. The difference between the two systems isn’t whether it’s battery-powered, as the name might imply, but if the sensors in your home (when you need more than one) are interconnected through hard wiring or not. Even if you have hard-wired alarms, each device will likely require batteries for backup in a power outage.
What causes smoke alarms?
There are several reasons why fire alarm may sound occasionally. The most common reasons are:
Batteries are not inserted properly: If your battery is partially empty, the connectors may not be connected properly, causing squeaks.
The battery pull tab has not been removed: Even with a hard-wired alarm system, you will need to remove the battery pull tab, allowing your device to use back up batteries in a power failure.
Unclosed battery compartment: If you do not close the battery compartment entirely after inserting or replacing the battery, an alarm will sound to get your attention.
Low battery: The most common cause is a low battery. The chime means that you need to install a new battery.
How to stop the smoke alarm from going off with a battery
Regardless of the actual source of the chirping, there are several vital steps to take to identify and replace your battery:
Locate Alarms That Are Going Off: While some apartments and tiny homes will only have one or two alarms, larger homes must have multiple alarms, and you’ll want to make sure you stay alert. Resolve the source of the problem.
Accessing the battery compartment: Due to the confusing wiring and connections, it is not recommended that you obliterate the alarm but take that battery. If you can maneuver the notice enough to reach the battery compartment fully, that should be enough to turn the battery off.
Open the battery compartment and remove the battery: By completely removing the battery, you will be able to check the pull tab to confirm that it has been removed.
Reinsert Existing Battery: Try reinserting the current battery while confirming that the battery is inserted correctly with all connectors connected. After the battery returns, wait a moment to see if the chirping resumes before placing your alarm back in the cradle. If the chirping has stopped, the battery may be loose, or the drawer is not fully closed.
Replace the battery: If the chirping continues, it’s time to replace the battery. When returning, make sure you close the drawer entirely and securely insert the battery. We recommend that you schedule a battery replacement for your detector every year. Additionally, manufacturers recommend completely replacing all of your sensors after ten years.
How to stop smoke detectors from buzzing without batteries
With a hard-wired system, it’s essential to realize that you may have spare batteries inside your alarm and need to replace them frequently. Unlike alarms that don’t connect, you can’t just pull them down and change the battery. You will have to maneuver the device to reach the battery.
However, if your hard-wired smoke alarm doesn’t have a backup battery, you should take other steps:
Remove each chime component: After turning off the breaker, take down the individual part, remove the backup battery (if any), then hold the test button for 15 seconds. This will reset your alarm and stop the chirping. Different brands may have other resetting methods, so it’s best to consult the manufacturer’s recommendations for resetting your particular alarm.
Clean the device: Dust and other household debris can get into your alarms and cause problems with their delicate sensors. Use can air or a small brush to clean smoke alarms.
Replace your device: If you’ve tried replacing the battery, resetting, and cleaning your device, and it still sounds, you may need to replace your smoke alarm.
