Functioning smoke detectors are extremely important in maintaining the safety of your home. Smoke detectors need to be replaced every 10 years, and smoke detector batteries should be replaced every 6 months.
You may need to replace your smoke detector The process takes just a few minutes and only requires a screwdriver and some electric tape.
Locate all of your smoke detectors.
There should be at least one detector on every floor of the house, including finished attics or basements. You may even have multiple smoke detectors on each floor, so make sure to check every room.
The location of the manufacture date should be easy to find but varies by model. If you find a smoke detector that is over 10 years old, you should replace it immediately. If you can't find a manufacture date on the smoke detector, the detector is probably over 10 years old and should be replaced.
Find the button on the face of the detector and hold it for at least 5 seconds. If the smoke detector beeps, it is functioning properly. If the detector does not beep, something is wrong.
You may hear all of your smoke alarms beep while only testing one of them; this is normal, and indicates the smoke detector in question is functioning properly.
You can buy an aerosol can of smoke to test your detector if you wish.
Shut off electricity to the detector.
To do this, you’ll need to find your circuit breaker and switch off power to the smoke detector in question. This will remove the danger of electric shock resulting from touching open wires.
Remove the old detector from the mounting.
Usually this will just involve a quarter turn counterclockwise. The unit will now be suspended from the ceiling by three wires, all connected to the detector via one plug called the wiring harness. These wires are:
Red or Yellow - Interconnect: This is the wire that connects the alarm with the remaining alarms in your residence.
Unhook the wires from the detector.
Ensure the power is off.
If you haven't done so already, make sure to turn the appropriate circuit breaker to the “off” position.
Attach the new wiring harness.
The new smoke detector should also come with a wiring harness very similar to the one you removed. Match the wires and attach them by twisting the metal ends around each other. Wrap the newly attached metal ends in electric tape or attach a wire cap. Attach the wires in the following manner: black to black, white to white, and red or yellow to the color of the third wire in your ceiling (this color can vary).
After attaching the wires, pull down slightly on the wire harness to make sure you have a good connection that can support the weight of the alarm. If the wire harness comes undone you will need to reattach the wires, making sure to wrap them tightly around each other.
If there are only two wires, you may only need to attach black to black and white to white.
