Testing Smoke Alarms

Smoke alarms are sensitive lifesaving devices and provide early warning in the event of a fire, therefore it is vital that regular testing takes place to ensure correct operation. Incorrect location and poor maintenance can affect the device.

Mid & West Wales Fire and Rescue Service (MWWFRS) recommend that smoke alarms are tested and maintained in the following way.
  • Once per week by pressing the test button until the alarm sounds.
  • Clean once per month by vacuuming around the alarm and wiping over with a damp cloth to remove any dust.


The alarms provided by MWWFRS have a 10-year battery life and at the end of its life the alarm will bleep once every minute for a minimum of one month.

For any other indications of a fault please refer to the manufacturer’s instructions that accompanied the alarm.

If you have a fault with a hard wired alarm, then please contact an electrician or your landlord if in a rented property.
