Why Is My Smoke Alarm Beeping?
A beeping smoke alarm can be annoying, but it's a critical safety warning. It usually indicates a low battery, a fault, or that the unit has reached its expiry date.
Important Safety Warning
Never disconnect a smoke alarm to stop the beeping without replacing it. Your safety depends on it.
Common Signs & Symptoms
- Intermittent 'chirp' every 30-60 seconds
- False alarms when cooking or showering
- Continuous sounding without smoke present
- Yellowing of the plastic casing (sign of age)
Potential Causes
Why is this happening? Here are the most common reasons we see in WA homes:
- Low 9V backup battery (most common)
- Dust or insect ingress interfering with sensors
- Expired unit (Smoke alarms last 10 years)
- Power fluctuations or loose wiring
Troubleshooting Steps (DIY Safe)
- 1Check the date of manufacture on the unit. If older than 10 years, replace immediately.
- 2Vacuum around the mesh to remove dust or bugs.
- 3Replace the 9V backup battery (if applicable).
- 4Press and hold the 'Test' button to reset the unit.
DIY vs Professional
In Western Australia, it is illegal to perform your own electrical work. While you can change a lightbulb or reset a switch, anything involving wiring or removing fittings must be done by a licensed electrician.
