Beeping Smoke Alarms

There are several reasons as to why your smoke alarm could be beeping intermittently or occasionally going off (when there is no fire!)

Smoke detectors work by using a tiny beam of light that sets the alarm off when it is broken. Ideally this only occurs when there is smoke breaking this beam, however this can also happen as a result of things such as:

  • Dust
  • Steam
  • Hairspray
  • Insects
  • Aerosols in general
  • Vapes

E.g.very occasionally it is possible for your smoke alarm to go off after having a very long shower. 


If the batteries in your alarm are running low or have run out, this can cause the alarm to beep at regular intervals.  There will be a stock of batteries in your home which you can use to change the batteries in your smoke alarm - they will either be double AA or 9V.

If you are sure none of the above things are affecting your smoke alarm, you have changed your batteries, and your smoke alarm is still beeping or going off, please let us know by getting in contact with the maintenance team.
