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.

Reviewed in the United States on March 20, 2024

I bought this since we often stay in vacation rentals. This is a nice portable reassurance, since the last thing I do is check smoke and carbon monoxide alarms when I travel. Although this is fairly compact (probably 4-5 iPhones stacked on top of each other), it is not quite as small as I would otherwise prefer.. Nonetheless, it is easily packed in a suitcase or travel bag to take along on your next trip. The thermometer is a nice added feature.

5.0 out of 5 stars Trust Matters
Reviewed in the United States on February 1, 2024
Pattern Name: DetectorVerified Purchase
When buying a life safety device such as this detector, I would not take a risk with any product that is not UL certified. I bought two detectors to have a backup (two different brands) and this is the better of the two. The temperature displayed on the LCD is a nice bonus as it turns this unit into something useful instead of just an ugly plastic brick. I haven't been able to test the 10 year battery, of course. It is useful to know that there are real technical reasons to have the 10 year life limit on these detectors. The actual gas sensor used internally has a limited lifespan, so the 10 year expiration of this product is not a sales gimmick. You will find the same lifespan on other products, including those that case twice the price or more.

4.0 out of 5 stars Nice, small CO detector
Reviewed in Canada on August 12, 2017
Pattern Name: DetectorVerified Purchase
This is a quite small (5" x 2.5") and nice looking carbon monoxide detector that can be unobtrusively put on a dresser or hung on the wall. It shows the temperature all the time, but not that the CO is at zero which I wish it did to ensure it's doing its job properly, the only reason for a 4 vs 5 rating. Other than that, it's fine.

3.0 out of 5 stars Good item but doesn’t display Celsius
Reviewed in Canada on February 5, 2018
Pattern Name: DetectorVerified Purchase
Just bought three of these to replace outdated plug in style CO alarms.

Nice compact size with clear displays and easy to read warnings, should we ever have CO incident!!

While the thermometer function is only a “nice to have” and not critical to the function, this item should have the ability to switch between Fahrenheit and Celsius to be sold in Canada.

The description doesn’t clearly state this limitation and neither does the instruction booklet. The LCD has an element for C but there is no way to make the switch.
