How often should these be replaced. Mine are dated 2011.

They are hard-wired to start beeping at you after 10 years, which I think is a requirement for CO detectors (used to be 7). I see no reason to replace them sooner than that.

Firex units have a self test mode within them to ensure the CO function is working properly. If it fails the tests you will get a warning signal. So no matter if it is 5 or 10 or 15 years it will let you know if it thinks it is not working properly.

My Electrical Supply Company tells me they should be replaced every 5 years.

A quick scan of the manual says 10 years. Code says all detectors in residences be replaced in 10 I believe. I use after 7 as a rule of thumb. M

I just spoke with customer service at USI Electric and they must know these are crap. Mine were manufactured in JUL 2009 and for $11.00 they will replace them. Just have to send defective units back to them with a check and a return address. You may want to call to confirm that they will do it for you.

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert

I don't know, mine were good for 3-4 months. If you contact the seller maybe they can tell you.

I am not sure. I have only recently started replacing ones at the business that I work at.

I bought mine in 2011 and it goes to 2016. I presume that they all cover a 6 year span: year of manufacture + 5.

As long as you cleean them properly they last. I have had mine for 2 years, just brought em out last week for a project and works great. Just be sure to properly disassemble and clean them and thes are a fine investment

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

I heard they have an exp of 5 yrs. Mine are dated with an exp of 9/18 and I got them in November 2013.

I have a expiration date of 04/2014. So they are still good for a while. You should get them used up by than.

Those I received have worked well thus I have not looked at warranty. Cheaper to just replace them.

Mine usually only last about one year. Then you have to toss it and buy another. I'm on my 4th.

Hi Jeffrey, I haven't had to replace mine yet. I still have the original ones I bought in May of 2013 (1.5 years), about 20k in miles on the car with about a 1/3 of them at night.

Have you replaced the heads? It is recommended that they be replaced every year. Hope this helps.

I seem to have to replace mine every 18 months or so. Really depends on how much tv you watch.
