What to do if the smoke alarm North Yorkshire Fire & Rescue Service fitted for you has a low battery and is chirping or faulty.

 How do I get a replacement?image of front of a smoke alarm with test/silent button

Where possible we would ask you to contact FireAngel directly. They will send you a new smoke alarm in the post. This will be free under its 10 year warranty as long as it hasn’t been damaged or tampered with.

Am I at risk from fire while I wait for my new alarm?

The smoke alarms we fit will continue to detect smoke and go off for up to 30 days after the low battery warning chirping starts.

The chirping is keeping me awake at night, can I stop it?

The 10 year smoke alarms we currently fit have a ‘Sleep Easy’ function. This means you can temporarily silence the chirp for 8 hours by pressing the test button. After 8 hours, the audible chirp will start again. The Sleep Easy push button feature can be used a maximum of 10 times.

Will I need DIY skills or tools to fit the replacement alarm?

All FireAngel alarms we fit use the same backplate. The backplate can be left in place and just the alarm removed and replaced by twisting the alarm. No tools are needed.

What if I can’t safely swap the alarm and I have nobody who can help?

If you have no way of safely changing your alarm without assistance from ourselves,  please ring us on 01609 788545 or 01609 780150 to discuss.

Don’t worry we will still be offering advice and support on fire safety and visiting people who really need our help to stay safe.
