Answer: 
Yes, I have replaced the batteries and it won't stop with the chirp/voice warning that batteries are low. I replaced to a different brand of battery - still won't stop. I just disconnected it (hard wired too) and will return to the store to purchase another one. Very annoying.

Customer Reviews

Rated 3.9 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Easy to install Fortunately we haven't needed to use the alarm yet for either smoke or carbon monoxide. But it is a good upgrade on the contractor grade alarms that the builder installed August 18, 2016
Rated 2.0 out of 5.0 by Replacement for one that failed Bought 5 for a remodel of an older home. One was defective after a time and I replaced it June 28, 2016
Rated 5.0 out of 5.0 by did the Job I could no longer test my 5 year old version of this product. So I switched it out for a new version that takes AA batteries rather than 9 volt batteries. Very easy switch out. February 10, 2016
Rated 3.0 out of 5.0 by Too difficult to install This was too difficult to install because it had to be hard wired. I'm sure the detector/alarm is good but I exchanged it for one run by battery only. January 19, 2016
Rated 4.0 out of 5.0 by combo detector the detector does what it is supposed to. Typically, these devices are too expensive, and you are lucky to get 5 years out of these 10 yr life promotions. December 15, 2015
Rated 4.0 out of 5.0 by Good replacement Fairly easy to install--of course, it wasn't quite the same size as the one I was replacing, but it appears to be a good product. October 29, 2015
Rated 5.0 out of 5.0 by It works We were doing some remodeling, and the building inspector said we had to put in CO detectors. I replaced our two old wired smoke detectors with two of these. After they were installed, a worker was demolishing our old wood floor, which generated a wood burning smell. Suddenly we hear "Beep Beep Fire Fire" from the smoke alarm, so at least we know the smoke detector and voice alert works. Hopefully we won't ever hear the CO alarm. August 4, 2015
Rated 5.0 out of 5.0 by AWSOME & PRETTY, stylish & useful NEW SMOKE DETECTORS, YEA. needed them for awhile. THEY WORK GREAT August 11, 2015
