carbon monoxide detectors lifespan image
Phillip
The CO2 Monitor has started beeping about every 5 mins, almost like a battery needs to be changed, but the only battery is the big battery backup for the alarm system. Does anyone know if this thing might have a sensor that needs to be changed?

Hi Phillip,
I've installed many CO (carbon monoxide) detectors, and all have specified a lifespan of about 5 years. After the useful service life listed by the manufacturer, they should be replaced.
Yours may be different. Try googling the model number to find mfr's literature on it. Or, contact the installing company for advice.
I hope this is helpful, and good luck.

None of my fire alarms went off?
Harry
Yesterday my home got full of smoke due to a malfunctioning wood pellet stove, which I was tending to, what called my attention w so much smoke why none of my 10 smoke detectors went off.
The batteries are only about 6 months old, and they're the kind that are hooked up in series thru the 110V circuit and the battery is only for back up in case of a power failure. I tested each one by pressing the test button and ALL tested fine, but when I blow smoke on them, they just do nothing, they're less than 6 years old, I understand 1 or 2 may go bad....but all 10? a few of them are dual smoke/co2 combo, those dont work either, theres power on the line. Anyones opinion is valuable, but that know a lot about smoke detectrs please, chime in....Thanks!!
Ok, I meant parallel, the system was installed by professional electricians when the home was built in 2005, the manufact. date of the units is march 2005. I tried blowing air, vacuuming, no change they:re KIDDE 21006378 and the co combos are KIDDE KN-COSM-IB .
I left out that in the beginning they worked fine, Im going to try some more suggestions and get back. for the time being, temporahily, I got 2 new units from First Alert they're the battery only type,and they pass the smoke test nooo problem Thank you to all of you that answered.

Hi Harry,
Smoke detectors should be cleaned using compressed air, as others have said. Testing with actual smoke is also more accurate than just using the "test" button.
Be aware that smoke detectors do have a set lifespan. Most manufacturers recommend replacing any smoke detector after 5-10 years. The same is true for carbon monoxide detectors. Most of these that I've installed specify replacement after 5 years.
Check with the manufacturer, and see when they recommend replacing their units.
Sounds like you're really doing your homework. Good job!
