Siterwell GS886-H02 Standalone Smoke & CO Detector with 10-Year Battery

Great to have the combo of smoke and carbon monoxide in one unit. Easy to install and gives me peace of mind. Ten year battery is another great idea. Highly recommended.

It replaced a First Alert unit, which was past its service life. I was able to use the same mounting site and screw anchors. EAS

This SITERWELL Smoke Detector Carbon Monoxide Detector Combo 10 Year Battery is wonderful. Did you know that you need to swap out your smoke detectors every ten years or so? I didn't until a year or two ago, and since we have been in our home for 30+ years... we had a few to change out.I love that this detector is a combination smoke and carbon monoxide detector. And I certainly appreciate the long battery life. Installation was quick and easy, and yes, the test beep is super loud. The voice is a bit weird, but it certainly gets your attention.I feel this was a great value for the price and am happy with the purchase.

Luckily I have not had occasion to test whether this works, but the test functions work and it was easy to install.

The media could not be loaded.

This product has a 10 year battery installed no need to change. Carbon monoxide detectors are critical to have in your home if you have any gas appliances or grills, or even wood-burning fireplaces. Instructions say to be installed by a professional person. We installed this easily ourselves, but I would recommend if you were unsure with the directions, to have it installed by professional. There are only criticism of his product would be that we wish the voice was louder. The alarms are very loud as you can see from the video.
