My smoke alarm is beeping but there is no smoke - what should I do?

What to do when your smoke alarm sounds but there is no sign of smoke

The most likely reason for an alarm sounding - without the presence of smoke or a fire - is dust inside the cover unit.

If every alarm on the system is sounding, a rapidly flashing red light on the cover of one of the units will show where the alarm was triggered.

The alarm can be silenced by pressing and releasing the test / hush button on the cover of the triggered alarm - pressing and releasing the test/hush button on different alarm cover unit won’t silence it.

After the test/hush button has been pressed there will be a 10 minute period of reduced sensitivity, indicated by the red light flashing once every ten seconds.

The cover unit should then be cleaned by running a narrow nozzle attachment of a vacuum around the smoke entry slots, which should remove any dust, fibres or insects that may be within the sensor chamber of the alarm.

The film below shows you how to stop your smoke alarm making unwanted noise.
