Product Overview

Intelligent combination alarm offers you and your family protection from fire and carbon monoxide. The intelligent combination alarm uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you and your family from carbon monoxide. Voice warning alerts you to the type of danger present. The Intelligent Alarm combines the detection capabilities of an ionization smoke sensor - which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires - with that of an electro-chemical sensor, which is used to detect CO. 10 Year Warranty.

Do the individual units communicate with each other?

Just curious if one goes off will the others. Is any communication between units done wirelessly or via connected wire?
Asked by: Curious
I don't think they would have to talk to each other, they would just go off when either the smoke or the gas would set them off.

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!!

Rated 4 out of 5 by from Decent product The alarm didn't detect anything as yet but I give it 4 stars because there's a design flaw when opening the battery door. there's 2 red spring loaded that sit upright when no batteries are in and it blocks the door from opening. Had to use a pen to push it down while trying to open the door.

I have just installed it by my furnace, but as of this writing it hasn't went off. When I installed the batteries it sounded like it should work and I liked having two different alarms, one for fire and one for gas leak.

Easy to set-up, voice alarm and sound alarm are very loud. Only issue is that the green standby light only blinks once when you test it and it does not blink afterwards to ensure that it's working (like a standard smoke alarm)
