How To Reset Smoke Detector? – Troubleshooting Guide

The steps to reset your smoke alarm can vary based on the type. For example, if you have a battery-powered smoke detector, it is a little easier to rest compared to an electric smoke detector. This is because electric smoke detectors tend to have a backup battery. 

Here’s how to reset a smoke detector: 

1. Turn off the main circuit breaker.
2. Remove the circuit breaker from the wall.
3. Remove the battery.
4. Replace the battery and remount the detector.
5. Turn the breaker on and wait for the alarm to sound.
6. Hold the test button until the alarm sounds.

Let’s break down these steps in more detail and help you get your smoke detector reset. Keep in mind that if you have a battery-operated smoke detector, you can skip to step three, as steps one and two are unique to electric smoke detectors. 

This is an important step in the process of resetting electric smoke detectors because messing with anything connected to power can be dangerous. So, turn off the main circuit breaker to help prevent any accidents while resetting your smoke detector. 

If you have never turned off your main circuit breaker before, let’s go over some things you may want to know before you do it. First, turning your circuit breaker off should be done sparingly. Doing this every once in a while will not harm the breaker, but repeatedly turning off the main breaker can cause electrical hazards and harm it. 

Only turn off the circuit breaker when necessary to prevent any damage. However, doing this once in a while will not be harmful. So, don’t be afraid to do it when necessary. 

Another important thing you should know about turning off your residence’s main circuit breaker is that it causes unexpected power loss to your electronics. This could cause a problem for some of the items you own. If you are worried about a sudden loss of power in your electronics, unplug your electronics before turning the breaker off.

After turning off the main circuit breaker, you can begin to reset your smoke detector. You’ll need to remove the circuit breaker from the wall and disconnect the power cord. 

Start by grabbing the smoke detector and twisting it counterclockwise. This will remove it from the wall, allowing you to access the inside. Be careful during this step because the removable part of the smoke detector will still connect to the wall with a cord. 

Carefully pull the detector down once you detach it from the wall and locate the cord that connects it to the wall. If there is no cord connecting the smoke detector to the wall, then your detector works on battery power only, and you can move on to step three. Otherwise, you will need to remove the cord to completely cut off the power source. 

Next, you want to carefully remove the cord or cords that connect to your smoke detector. These wires supply power to the detector, and you should only remove them temporarily to reset them. If the wires connect to the detectors with just a plug and socket, go ahead and remove them. 

Sometimes, this is not that easy to do. The cord may connect to the smoke detector via wire nuts. This can complicate removing the cord, but it doesn’t make it impossible. In this case, all you need is a screwdriver. Use the screwdriver to remove the wire nuts and disconnect the cord, freeing the smoke detector.

If you had skipped to this step after omitting steps 1 and 2, remove the smoke detector by twisting it counterclockwise. Once you remove it but fail to see any cord connecting it to the base, you’re all caught up. Now, it’s time to remove the battery. 

All-electric smoke detectors have a backup battery. This is to keep residents safe in the event of a power loss. Thus, you will need this step no matter which type of smoke detector you have in your home. 

Remove the battery from your smoke detector by pulling it out of the detector and disconnecting it from the connector. This will fully shut down the power of the smoke detector, allowing it to 

completely reset.
