CO alarm went off then stopped

[Guest Guest TP]

Hi.

i was woken up at 5am by my Smoke/CO alarm beeping 3 times then completely stopping. It is a Kidde model and didn’t say either “fire” or “CO detected”, it was literally just 3 beeps.

I have since tested the alarm using the test button and it works fine. It has made no noise since. Should I be worried?

Thanks

Thank you for posting this question on the Safelincs Forum. It is important to use the alarm in accordance with the user manual supplied with the alarm unit to ensure correct operation as per its design. Optical smoke detectors are particle detectors and it is possible that the sound you heard was a ‘transient event’ caused by particles or insect activity (such as very small flies or spiders). Carbon monoxide gas would cause the alarm unit to emit four beeps – see user manual for details.

The test button is a full function test of the alarm so as you have pressed it and the alarm responds correctly this would mean that the unit is capable of detecting smoke or carbon monoxide gas provided it is used as per the user manual. It is important to maintain the alarm and follow the information on the user manual: ‘General Maintenance To keep your Smoke/CO Alarm in good working order, please follow these simple steps: 1. Verify unit alarm, lights and battery operation by pushing the test/reset button once a week. 2. Clean your alarm monthly using compressed air or a vacuum cleaner hose and vacuuming or blowing air through the openings around the perimeter of the alarm. If cleaning does not restore your alarm to normal operation the alarm should be replaced.’

The 10SCO has a ten year warranty and Kidde do treat warranties very seriously. You can contact Safelincs or Kidde for assistance.
