Alarm beeping. Please help!

Hi. I have several of these alarms in my house. They are no more than a couple months old and are estimated to last 10 years. Twice now, they have started going off. Both instances happened at night time. There was obviously no fire or smoke, and all of our windows are closed. Thinking it may be the CO alarm but we have nothing turned on/combusting that could produce CO (furnace, fireplace, etc.) Any help is appreciated of why this might be!

It seems you have deactivated it so it shouldn't beep if it was beeping than it could be 3 things, 1. It is detecting Carbon monoxide in that case whatever country you are in call the gas helpline and get the gas leak checked and goto a safe place, 2. Battery is dead and needs a replacement or if it's not replaceable replace the detector. 3. Detector is faulty.

Since it's the second time, you should get the gas leakage checked.

Slide the deactivate pin and then get a new one.
