Product Description

The First Alert CO710 Carbon Monoxide Alarm with 10-Year Battery and Digital Temperature Display detects dangerous carbon monoxide for up to 10 years. This carbon monoxide detector uses an electrochemical carbon monoxide sensor, the most accurate CO detection technology available, to detect the CO you can't see, smell, or taste in the air. A built-in 10-year lithium battery means you never need to worry about changing batteries during the lifetime of the alarm. This stylish CO monitor is designed to sit on top of a dresser or tabletop, and it has a backlit digital display that clearly shows the ambient temperature, as well as current and peak CO concentrations. An 85-decibel horn sounds if carbon monoxide levels are too high, and a test/silence button silences the alarm and allows you to test its functionality.

A great replacement for the First Alert CO1210 purchased from Costco from 2015-2016
4 Stars
A great replacement for the First Alert CO1210 purchased from Costco from 2015-2016
I purchased three replacement First Alert CO710 Carbon Monoxide Detectors from Amazon and was pleasantly surprised when the driver pulled up at 6:00 pm on the same day with the new units.The CO710 is easily installed with a Philips head screw driver. The only complication was that my old CO1210 was installed with screws mounted 2.5 inches apart. The new CO710 is designed to be installed 2 5/8" apart. The 1/8" difference means you can't slide the new unit in place without tools.My solution was to:1) Loosen both screws a few turn to accommodate the new screw brackets on the CO710.2) Unscrew the left screw 1-2 more turns. GENTLY bend the left screw outward (to create 1/8 adjustment).3) While holding the left screw at a slight angle, tighten the screw two turns.4) The CO710 should now slide on to your existing screws.The second photo shows how I adjusted the left screw. Hopefully these instructions will make your easier.
