Questions & Answers

Since it is smoke detected, will cig. smoke make it go off?

Since it is smoke detected, will cig. smoke make it go off?
Asked by: Snuggy
No, smoking does not set it off. I did have a small carpet fire and the smoke detector did NOT GO OFF. Makes me wonder how big a fire must be to set it off? Of course I tested it after the incident and it was working fine?

Do I install on the ceiling like a normal smoke detector? Or does the CO detector require lower placement?

Do I install on the ceiling like a normal smoke detector? Or does the CO detector require lower placement? I heard that CO detectors should be placed low to the ground because carbon monoxide is heavier than air.
Asked by: Erica

Intelligent Battery Operated Combination Smoke and Carbon Monoxide Alarm (2-Pack) is rated 4.5 out of 5 by 186.
Rated 5 out of 5 by from Great product I bought this item because I liked the 2 in 1 feature. It was very easy to install.
Date published: 2017-08-02
Rated 5 out of 5 by from 7 yr lifespan, worth price mine just went out last week, after 7 years of faithful service, with no malfunctions along the way. Kiddie makes a great detector, and they have never let me down. This is a great buy, but they do have an even better model out now. This time around, I will be upgrading to the li-ion battery version with a 10 year lifespan ... that's three extra years of expected life, and no batteries to change, plus you get to keep all the same features. And at about $10-$15 more than the standard AAA version, the "higher" price really just buys all those AAA's that you won't need to install... saving you time, and putting less batteries in a landfill!!

The only problem was some ignorant customer must have opened the package and stole the two batteries that were suppose to come with the item. I was able to scrounge up fifty cents to buy two batteries to keep my family from dying from C.O. or smoke.

I rated this a 3 because I think the green light that blinks every 60 second when it's in normal working condition should be so much brighter to let me know everything is working instead of standing and looking at it to make sure it's working.

Rated 3 out of 5 by from seems ok It seems to be ok. It has worked when i tested it. I was told by a fire inspector to avoid the ionization type smoke alarms. He said the photo electric type are more reliable. I wouldnt have spent $40 on this one had I known that.

True, mounting and setting is very simple, but I won't know if it works well until there's a necessity for it to go off.
