CO Alarm

The process of purchasing the new CO Alarm was fine. I did though like the old model CO5120PDBN, with the digital display better than looking up what the beep sequence is indicating.

Mounting Issues

Alarm does not stay affixed to base - purchased 2 units and had to use double side adhesive tape to secure the units to their base.

Purchase review

Ordered carbon dioxide detector from First alert store. They processed and sent the detector without delay. Called with mailing concern and they quickly and efficiently helped. A great Co. to work with and product is exactly what I needed. The web site is great. Thank You First Alert!
