Is this unit dated 2007? I understand that alarms need to be replaced every 10 years from manufacturers date, is that true?

The expiration date does not appear on the back of the alarm. It's the date it was manufactured.

Generally yes. especially the carbon monoxide detector needs to be replaced every 10 years.

I would recommend you go here to read up on what the insurance industry has to say ... http://www.theagentron.com/blog.php?id=89There should be a date printed on the back of the smoke alarm, which is its expiration date. In the First Alert brand alarm, the expiration date is located right beside the battery compartment.

The box it comes in is dated 2013 and I assume that is the manufacturers date too. I do not know about 10 years - just that batteries need to be replaced annually at time change.

The units I received were dated 5/2013. I received them 7/2013. The vendor guaranteed that they would be fresh units and they were. The ones they replaced were close to 10 years old. The smoke component was still active, but the CO wasn't. The CO function can wear out any time after seven years.

Mine seems to last a couple months. Not overly thrilled with the alarm because it would go off all the time for no reason and now it seems to be working fine.

If you check the back side of the unit you will see a label which has various pieces of information including a manufactured date. I quite sure you'll find it is probably six or more years old. That being the case, the unit must be replaced. It's useful life has been reached. It is designed to be this way. New batteries will make no difference.

I wish! I had 120 in an apartment building and couldn't even begin to tell you of the countless false alarms we've had since they were installed in 2010. I never found one to mix and match with these. If it is hooked into a relay check that too as sometimes that is the problem.

I don't know but what I can say about that piece of junk is:It developed a problem after about a monthCobys warranty wanted me to ship it to them for service at my expense (which is normal)BUT they wanted me to send them money for the return ship to me.AIN"T GONNA HAPPEN! I sent it back to Amazon for refund and bought another brank thats been fine for, I think 1-1/2 to 2-1/2 years now. I'm sorry but I don't use it for an alarm so can't comment on that.

I used the same brand. The sensors after about 10 years will begin to fail. After discussing the issue with tech reps from the manufacturer I replaced all of the detectors with the new replacement model and have had no problems.

Same problem here. I had it happen with two of the units over a 4 year period. Not going to fool me again.

Hi, There's not an alarm on mine. I've had it for over a year so maybe it's not the newest model?

I have no idea. The two units I have were installed when my place was built around 2003-2004. Only one has failed so far (about a year ago now). When I replaced it, I didn't bother to take apart the old one to see why it wasn't working.

The info says 7-year end-of-life warning alerts user to replace CO alarm (40 percent longer than other CO alarms). I always put a date on the device itself, as well as on my calendar so I know when to replace it.

I believe it said 10-15...but the unit begin going off randomly about 3-5 years in, and to claim warranty (if you can get them to agree)...they will make you ship it to them. The unit only costs $13. It's hardly worth the trouble to claim a warranty IMO.

From what I've been reading, previous to September 2014 there were issues with the alarm going off for no apparent reason. But that software has been updated and the problem has been resolved. I purchased 3 of the hard-wired ones the end of December 2014 installed them mid-January with no problems. I test all 3 the first day of every month as well. Great product!

Had mine since 2010 or 2011. Just keeps doing its thing so far without incident.

Yes. It is time to replace it. I have the same problem now. It is supposed to last seven years.

The battery seems to last a long time .I have had mine for over two years and I may have replaced the batteries once but I am not even sure about that. Bottom line is: how long the battery lasts should not even be a consideration when deciding to buy. I love the darn thing. I just wish I could find out how to turn the alarm off.

The battery is not the issue. Smoke detectors should be replaced every 10 years (actually 86,000 hours) whether or not they have replaceable batteries. This is why the unit has a 10 year battery. So that it will be maintenance free for its entire lifetime, and you will be forced to replace it after that.And yes, it probably does make them more money, but it's a matter of statistics. Your particular detector may still work at 15 years, but the vast majority don't at that age. It's a matter of risk management. I'd hate to loose my house (or part of it) because I tried to stretch $20 out another few years. The battery is not the issue.
