    Comments about First Alert® CO Detector (CO615):

    I bought this product as soon as I moved into my home. Home is 19 years old. I disconnected all ADT monitors so I bought this CO2 monitor since there are 2 gas fireplaces, gas stove and gas heat. 3 months after moving in, alarm goes off 5am one morning. Called gas company and they identified a leak coming from the valve in one of the fireplaces. Can't imagine what would have happened without this product! Thanks!

    Comments about First Alert® CO Detector (CO615):

    It was brought up that a fire department responded to a CO alarm recently and discovered that the First Alert CO detector model CO615 can be activated by a TV remote that is pointed at the unit and the channel up/down or volume up/down button held for five seconds. This is apparently a feature to test or silence the unit. This is the first any of us were aware of this, however it is noted in the 615 owners manual.
