That’s why we want you to test your detectors, and change the batteries if needed, on 29 February 2020, Leap day.
How do you test your detectors and how often?
You should test your detectors on a monthly basis and change the batteries twice a year, according to the London Fire Brigade.
To test your detectors all you need to do is press and hold the test button for a few seconds or until the alarm sounds. If the sound is weak or it’s been more than 6 months since you last changed the battery, you’ll need a new battery.
Best practice is to ask someone to stand in the rooms you are not testing the alarm in. You need to be able to hear the alarm in every room.
Don’t forget to keep a couple of spare batteries around your home in case they start beeping in the middle of the night.
Even if your detectors are connected to the mains, it’s important to test their back up batteries, which can be tested the same way as above.
Need some advice?
If you’re not sure whether your detectors are correctly positioned, or you need help testing them, the London Fire Brigade will come out and assess your home for free. They’ll even install new ones on the day, and free of charge.
