Smoke alarm beeping
A short beep every 30 to 60 seconds usually means a flat battery or an alarm at the end of its life. Smoke alarms last about 10 years. Check the date on the back.
What to do right now
- Press the test button to confirm the alarm still works.
- If the battery is replaceable, fit a new one of the right type.
- Check the date of manufacture on the back. Over 10 years old means replace it.
- Do not leave the home without a working alarm. If it must come down, replace it the same day.
It is an emergency if
You can see smoke, flames, or smell burning. Get everyone outside and call 000.
For fire, smoke, shock injuries or fallen lines, call 000 first.
Common causes
Low battery
The most common cause. Hardwired alarms also have a backup battery that runs flat.
End of life
Alarms last about 10 years. After that, they chirp and need replacing, not re-batterying.
Dust or insects
Dust in the sensing chamber can cause false alarms, especially in older alarms.
What we do about it
We replace old alarms with interconnected, hardwired alarms, so when one sounds they all sound, and test them before we leave.
Common questions
It beeps even with a new battery. Why?
Most likely the alarm is past its 10 years or has a fault. It needs replacing.
Can I take it down to stop the noise?
Only if you replace it that day. A home without a working alarm is the real danger.
