why does my first alert smoke detector keep beeping

1) Take down all the smoke detectors. IF you have a CO monitor also hard wired, take it down as well. 2) For each detector, open the battery compartment so that there is no power to the detector. Hold down the test button until all beeping stops to drain the capacitor. The detectors usually have a capacitor that holds some charge even after disconnected from power and battery. 3) Close the battery compartment so that the detector is running on battery alone. If it starts to chirp, repeat with a new battery. If it chirps with a new, good battery, try blowing dust out of the detector and repeating. If it still chirps, get a new detector. 4) Once all detectors are working on battery power, connect them to power one by one. If the detector starts to chirp, then try a different detector in that location.


If both chirp you probably have a wiring problem or connector issue at that location. If one chirps but the other does not, you probably have a wiring or connector problem on the chirping detector. I hope this helps. Most of this came from First Alert customer support. They were very helpful.

Before you replace that smoke detector or go out and purchase another new pack of nine-volt batteries, there are a couple things you should know about your smoke detector, and a few things you can do to address this problem. There are several different types of smoke detectors, however, the most current model detectors found in homes and apartments operate by low-voltage electrical wiring with a battery backup.


These smoke detectors have internal processors that store error codes, and a week battery chirp is a common error code that may be retained, even after the old battery is replaced. The only way to clear this error is to reset the smoke detector, which can be done by following these simple steps: * Turn off the power to the smoke detector at your circuit breaker. * Remove the detector from its mounting bracket and unplug the power supply. * Remove the battery from the smoke detector. * With the battery removed, press and hold the test button for 15-20 seconds. * Replace the new battery in the detector and plug in the power supply. * Restore power to the circuit breaker. * Reattach the breaker to mounting bracket.


When the power is restored, the smoke detector should chirp once. However, your low-battery chirping should no longer be a problem. There is one other thing you can do to reduce the possibility of ever hearing chirping from your smoke detector, and this is to change your batteries before the chirp is heard. A good rule of thumb and industry standard is to change the batteries in your smoke detectors every six months. October is fire prevention month and a good time to change all your detectors in your home. However, if your detectors are chirping, change your batteries immediately. If your smoke detector is more than 10 years old, the unit should be replaced with a newer one.


Detectors can be purchased at your local hardware stores, or your local fire department may have a program to distribute them. It is recommended that smoke detectors be installed in each bedroom of your home and a hallway. However, if you only have one smoke detector, placing it in the hallway outside of all bedrooms is the best location for placement. If you live in the city of Sacramento and would like to get more information on how to get a smoke detector installed in your home call 311 from a hard-line telephone.
