The common word about smoke and CO detectors is that the sensors go bad after a long period - typically eight years - Does this apply to this unit??

Yes. I purchased mine in 2008. Not a peep from it until this year, when it started chirping and displaying a low battery signal that would not stop even after batteries were replaced. I figured out it must have reached it's usable lifespan.

Sorry, haven't had it for that long; only for a couple yrs now and seems to work fine.

The short answer is "Yes." The longer answer is that the CO sensors slowly deteriorate with time and so there is (was?) an industry standard that has devices shut themselves down after a fixed period of several years and signal the need for replacement. It's a safety measure.

I am not s sure but why would you? The battery should last between 5-7 years and if the cost of the battery exceeds a new smoke detector then you replace the detector. Have to ask the mfg this 1.........

These things have a 5 year warranty and a 7 year lifetime. The ERR code likely means that the 7 years is up. Trace amounts of carbon monoxide can build up in the detector and render it ineffective, so the entire unit should be replaced after 7 years. Was it previously used before your two years? Check the manufacture date on the back.

Usually one year but mine had a bad burning smell after the third day and it took them forever to get back with me. I wanted to know if there was a fire hazard, a recall or if it was safe to use . It took 5 unanswered phone calls. I returned it the next day thru Amazon. They called me after I had returned it. Take your chances and good luck.

I purchased the batteries earlier this year to replace the batteries in my smoke and carbon monoxide detectors. I put one in my alarm clock and left it unplugged for 7 days. It is still working. The last time I did that the clocked stopped after two days. I cannot give you a longer time review than 6 months.

Thanks everyone for you comments. I have a carbon monoxide detector right out from my stove. We have also installed a fan over top of the unit. I guess it can't burn the fumes fast enough like gordyh was talking. If it gets worse will have a teck check it out. Again I would like to thank you all. Didn't think I would get a reply.

That's approximately the date the sensors will start to deteriorate. It will start beeping and keep on so, until you change it out. It will also keep beeping even without a battery for some 3 or 4 days.

I purchased an earlier version of this detector in 2008 and yesterday it began the 3-chirp per minute "end of life" warning. Once I checked the manufacturing date on the unit it became obvious why it was chirping. Planned obsolesce, some might say, but if the detection system is only good for a limited time then this is a good thing. I just purchased this CO615 to replace it. By the way, the 3 chirps come very quick together (at least on my old unit) - it would be easy to mistake it for a low battery chirp, which I thought at first.

Hi Kevin, 8hrs on a full charge of continuous recording mode. Up to 30days on Stand by mode. We do have other option IR smoke detectors that is 20hrs on our spysonic website as well if the 8hrs is not enough time for you.Thank You.

Mine did that a few times and it was one defective unit (garage) that kept triggering the system. They are quite sensitive to any kind of debris. You should also use a vacuum every 6 months and suck out any dust build up of the sensors to help prevent this.

I had read somewhere online that people had the batteries last 30days. I found that after 48hrs the motion detection started to be significantly less sensitive until I put fresh ones in again.

I'm not a "science" guy - just a homeowner who's had CO detectors for years. Mine are up high just where a smoke detector would be. Many friends and "experts" have seen them up there in my house. Nobody ever said it was not the correct location.

I had to replace one a few years ago. I believe I reset it so many times that the reset failed to function properly. I read Hippie Bob's suggestion and wish I had tried that before I discarded the original sensor. Good luck .

Good morning. I regretted having bought this alarm. It was a waste of money and would have returned it if only I could at that time. I hope this answers a question in your mind about the reliability of this sensor.

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

In our home we have a group of 6 smoke alarms, 2 of them being carbon monoxide detectors. They connect up to the wiring all the same, any way the ones I have replaced do, the smoke alarm/carbon monoxide detectors just preform more function.

I have 2... They last about 4-6 months it seems like, depending on how much activity they transmit. The sensor on your front door is going to use more power than a side door. Just my experience.
