Description
This First Alert CO710 Carbon Monoxide Alarm features a 10-year built-in lithium battery for continuous monitoring during the life of the alarm, and uses an electrochemical carbon monoxide sensor and an 85-decibel alarm to alert you to CO threats.
The advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes.
Because CO evenly distributes itself, it's important to have a CO detector on every level and in every bedroom of your home. This easy-to-use alarm features a digital display that shows ambient temperature as well as peak CO levels. The detector's stylish design looks great on top of a dresser or table.

Q: Does this work the same if plugged into a surge protector?

Q: How many PPM before this detects CM?
submitted by Dorothy - 8 years ago
A: Thank you for reaching out. First Alert’s carbon monoxide alarms are designed to alarm before there is an immediate life threat. Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and exposure times as described below. They are measured in parts per million (PPM) of CO over time (in minutes).
CO Level: 70 PPM, Alarm Response Time: 1 to 4 hours. CO Level 150 PPM: Alarm Response Time: 10 to 50 minutes. CO Level: 400 PPM, Alarm Response Time: 4 to 15 minutes.

False alarm
False alarm after 2.5 weeks of use. Wasted the fire department’s time and mine. Completely useless

Don't travel with this
Took this detector on an overseas flight to use in a rental apartment. Packed it in my carryon bag, because of airline lithium battery restrictions. Alarm kept going off in carryon, because of pressure on test button from other items packed around it. Finally had to disable the alarm to shut it up, which meant it could never be used again. Then had trouble disposing of disabled alarm in foreign country, because you can't just throw a lithium battery in the trash. What a waste of money.

I must have for travelers
I must have for people who travel. This is small and will easily fit in your suitcase. Although carbon monoxide leaks are rare, they are also deadly. This is so easy to take along. Highly recommend.

Temperatures are way off!
Just bought two of these. Thought the temperature was a nice idea. Bought it specifically for this feature. One reads 64 and the other 70.

Peace of Mind
In addition to only have to replace it every ten years, I like you can place on a table or shelf as I am not a big fan of drilling a bunch holes in the wall so I like that option.

Does not last 10 years.
Worked well for 3 years then died. 10 years is a stretch, not even 5 years.

Excellent CO2 monitor
First Alert is a name you can trust! I purchased this monitor for peace of mind. I vacation at VRBOs and feel much safer bringing my own CO2 monitor.

Malfunctioning after one month.
I have owned this unit one month and it’s already malfunctioning with the 3 chirp alarm.

Easy to read
[This review was collected as part of a promotion.] I am very happy with this item so far! I have young kids in the house and always take very precaution that I can. This was very easy to set up and is wonderful to read. It is small and fits very easily anywhere. I like that it doesn't have to be plugged in and runs on a battery. The battery does not last a very long time. I do like that you can mount it or just having it set up on a counter. I am so glad I got this detector, it definitely keeps my mind at ease knowing myself and my family is safe.

Works great
[This review was collected as part of a promotion.] This First Alert CO710 Carbon Monoxide Detector with Digital Temperature Display is excellent for the home. It is light weight, user friendly, and has a thermostat displayed on the front screen. The read of the thermostat is pretty accurate. The material it’s made out of feels sturdy. It has a blue lighting on the back screen and the alert beeping sound is not super loud or annoying. Can place it anywhere in the home or take it with you anywhere needed for extra protection. No need to mount it up on wall. Overall it works really well but if the battery dies ( says it will last 10 years) there is no replacement battery so you would have to buy another one.

Awesome features!
[This review was collected as part of a promotion.] This First Alert Carbon Monoxide Alarm is exactly what I was looking for! I love that there’s no installation needed - it sits right on the shelf or wherever you place it so no need to get out the toolbox. It also has a 10 year lithium power cell so no digging in the battery box hoping to find that one last 9 volt battery you know is in there somewhere and no more of those annoying low battery chirps!!! But my favorite feature is the digital temperature display. It’s just a handy little bonus in my opinion! I feel secure now knowing we’ll be alerted to any carbon monoxide leaks in our home thanks to this alarm from First Alert.

Easy to Install
[This review was collected as part of a promotion.] I trust this product. It was INCREDIBLY simple to install and has proven to be very durable. The battery life is fantastic and you can stick it just about anywhere. The instructions for use are incredibly easy. You basically just put it somewhere out of sight, sit back, and hope it doesn't tell you there's some kind of problem. Can't beat that at all. I also appreciated the fact that the instructions gave guidance on where in the room to put the device. I don't have a ton of experience with this kind of stuff, so knowing where I could and could not deploy the detector was surprisingly helpful. I'd hate to do it wrong and miss a problem!

I highly recommend these and definitely place them in multiple areas of your home. Great quality. Great value and well trusted brand. Seriously highly recommend.

Nice features
[This review was collected as part of a promotion.] After a couple local incidents of carbon monoxide poisoning here in town. I realized that it was way past time to finally get a proper high quality CM detector. Then i proceeded to do my due diligence in researching the huge variety of CM detectors out there. I finally decided that this was my best choice. Lots of excellent features ranging from the Parts Per Million detector, along with the temperature gauge and night time lighting feature, not to mention the ease of mind in knowing i have one less worry in this world.

Loud enough to hear!
[This review was collected as part of a promotion.] My family's safety is my number one priority. I have a carbon monoxide detector in every room. However, those aren't as easy to operate as the First Alert. It's runs on battery power unlike the other detectors, it doesn't need to be plugged in. It has a battery life that lasts for 10 years. Super easy to activate switch on the back of the unit. I tested the alarm and it's loud enough to alert you to evacuate when the carbon monoxide levels are detected. The digital temperature display is an added bonus feature.

Carbon monoxide detector
[This review was collected as part of a promotion.] I want to always make my home safe and the carbon monoxide detector is a product I want in my house. The detector is easy to read and install. Plug it in and that's all you need. The alarm is loud and can be heard on the next level of my home. I highly recommend getting this detector and installing in your home. I have carbon monoxide detectors installed in every level of my home because we had a carbon monoxide leak a few years ago. If we didn't have one installed I probably wouldn't be here rating this product.

Wonderful
[This review was collected as part of a promotion.] The first alert carbon monoxide detector with digital temperature display is absolutely perfect. The detector saved my family's life by being so extremely accurate. During a family trip we were in the car sleeping overnight and the detector went off causing us to wake up and notice a small fire coming from the hood. The detector is by far better than any other brand. The quality is outstanding and the value is spot on for providing accurate results and it can save your life. Recommended to all my friends and family.
