Smoke and Carbon Monoxide Detector Powered by Battery with Digital Display, Dual Alarm Sensor of Smoke and CO (3-Pack)

We have an older home and had one old fire detector. These detect fire and CO2 and are perfect to place them where need be. Light weight, easy to install and nice looking. I have mine hung on the walls but they can be mounted on the ceiling as well. Read instructions on how to place them correctly for proper detection (head space to ceiling/interfering walls/etc.). They flash green periodically, I have yet to have one run low on battery, which was my main concern. I purchased these months ago and they’re still going strong. Very happy with my purchase!

great value for the money 3 pack. easy to hang. very loud beeper for testing and even louder alarm

Out of the set of 3 we had one go faulty within 9 months and kept making alarm and showing high numbers up to 112 even with replacing batteries. We had the fire department come and check and they got a 0 reading. Guessing not replaceable. But we are alive and safe.

Shipping was fast. Alarms are easy to install & easy to test. Would highly reccomend especially in residential site where required. Flashing "On Power" button shows up brightly to show it's working correctly. Will buy more possibly for other family members homes to keep them safe. Thanks 👍

Got these for all three floors of my home… Carbon Monoxide is a silent killer… No mercy, no second chance… how can you Not buy these and know you’re protected !!!!

These alarms were easy to install and work nicely. They are of good quality and I would purchase again.

We recently took a couples trip out of the country. I was doing some research and heard about a couple that died due to carbon monoxide poisoning while on vacation. I got a three pack of the detectors and they worked great.

The media could not be loaded. Hope I never have to find out if they work. The led blinks.
