Is the operate light supposed to be on all of the time?

Asked by Amanda April 8, 2021

Answers

Hello Amanda, On battery operated units, the LED does not stay on all the time.

At what level of CO does this product alarm?

Asked by Marcia February 22, 2021

Answers

They trigger at once and before levels are deadly.

Mounting the unit

Asked by Jb February 17, 2021
5
Answers

I googled the best place to mount it...as for double sided tape, yes, it's a very lightweight unit. That should work. Here's the google answer on the best place to mount it: Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance. Good luck.

Does the kit include mounting screws/anchors?

If the shed gets quite hot or cold I wouldn't place it in there either way the batter or unit could be effected. The directions might show the "maximum safe "operating temperatures.

Appears to be a great value. I can't say how good it works yet because you can't smell or see carbon monoxide. If I'm still alive in 10 years it's either because it worked or I haven't had a carbon monoxide leak in my house. I did buy 2 of them because I wanted something to protect my family and I don't have a lot of money. I also bought 6 smoke detectors because out of every place I checked Home Depot had the best price easily. I think that they might be doing this on purpose to help keep people safe. Thank you Home Depot.

I’m so happy I bought this. I’m 60 years old and I’ve never had a carbon monoxide detector ever. Now I don’t have to worry about the deadly gas coming into my house killing me my pets and family. I only got this because the mortgage company made me. I don’t know how over the last 60 years I could of slept in this house without one. I know Greta Thunberg would be so proud of me. Now I can prance around my house safely and happy while listening to The Osmond Family album.

Unit works as required by city ordinance but the batteries outlasted the CO sensor inside. The projected life is 7 years but all of mine failed in about 6 years. The new ones are good for 10 years. Wonder why the manufacturer doesn't supply a plug-in CO sensor instead of making you throw the entire unit out, Could be expensive and labor intensive if you have many apts.
by Chuck
Response from Kidde ExpertJun 4, 2019
Hello. The price of the sensor is a large portion of the cost of the alarm itself. Making the sensor reliably replaceable would increase the cost of the alarm and the replaceable sensor might cost almost as much as a new alarm.

We purchased two of these detectors. We have a new house that has interconnected smoke detectors, but when I read about them it did not say they detected carbon monoxide. We have an attached garage, a gas fireplace and a gas furnace. Carbon monoxide could come from any of these. We would rather be safe than sorry. This detector is relatively inexpensive and easy to install. I would recommend it to anyone.

Easy to install. My previous Kidde CO alarm expired exactly 7 years to the manufacturing date. It's nice that the newer version comes with batteries and less for 10 years now.
