When the alarm goes on does it tell me if it's Gas or Carbon Monoxide?

When the alarm goes on does it tell me if it's Gas or Carbon Monoxide?
Asked by: Stan
Yes, the display indicates either GAS or CO. Also, the alarm sounds are different for each. The downloadable Use and Care manual (above) explains this.

CO heavy gas , natural gas is a light gas where to install

Co is a heavy gas and it recommends installing 3 - 4 feet from floor, natural gas is lighter and they suggest 12" from the ceiling , where is the best location for a CO/ natural gas combo detector
Asked by: JohnSOBOS
Everything I've done in research about CO says it's as light or lighter than air and should be installed up high...especially considering it's usually produced with warm air devices and therefore more prone to natural warm-air-rising currents. Propane, however, is heavy and sinks.

I see...Turned on the propane on all burners for a couple of minutes to perform my own "test" in my Aliner camper. This detector did nothing even with the malodorous gas reeking! Hope you're not without power for long. It drains a 9V battery in no time. Don't waste your money!

Rated 1 out of 5 by from Did Not Detect Gas Leak I got this unit primarily to detect gas leaks. After reading numerous warnings about the unit being too sensitive to install near the stove I did just that to establish if it was working. Encountering no alarms after several days I placed the unit in my gas grill, turned on the gas but not the igniter and closed the lid. No alarms after a minute of running the gas. I left the unit in the grill an additional 30 minutes after turning the gas off and still no alarm. The unit alarms as expected when pressing the test button. However I would not count on it working when exposed to real natural gas. I bought unit online and returned to local Home Depot store with no hassles.

Rated 5 out of 5 by from Saved my Life ! ! ! ! ! ! ! I purchased one when I moved in a month ago, It went off last week in the middle of the night. The CO level in my house was over 400 when the Fire Department arrived. A few more hours and I would have never woke up….. THANK GOD I INVESTED $40…. Now I have 3, 1 down stairs, 1 in the family room and 1 in the bedroom…...

Rated 1 out of 5 by from would not detect either gas purchased 2 of these units and assumed they work,but when I tested them with each gas neither one worked for propane or natural gas. Too late to return.

Rated 5 out of 5 by from Explanation of battery issue Just to dispel the myth that this detector "drains batteries" let me clear something up: The battery inside is a 9V and is intended as back-up if the power should fail in your home while you are sleeping. What is draining the battery is the periodic testing of the battery itself. The warning "beep" you hear is letting you know that the battery needs replacement because the remaining voltage remains too low to reliably power the gas sensors (and the alarm) for 24 hours should the power to your home go out. Do NOT recycle the 9V battery at this point because it still has plenty of life inside it to power a toy/remote/non-emergency/non-critical device! Engineers cannot create miracles. The goal of the backup battery is to avoid a "perfect storm" of conditions in your home that could result in harm to you and/or your family. If your 9V battery is requiring replacement too often (more than once every 3 months), chances are the battery is defective or, less likely, your device is defective. I do not work for the company; just wanted to explain. There was a very large natural gas explosion in Indianapolis last night; two people were killed and a over a dozen homes burned. a few 9V batteries a year is nothing compared to this loss of life and property.

Rated 5 out of 5 by from Easy to install and gives great peace of mind I purchased this for a friend of mine who has a gas stove, but cannot smell. When I was at her home I smelled gas and she suddenly realized one of the knobs was turned on slightly, but the pilot light didn't ignite the gas. The alarm was easy to install and it eases her mind about the possibility of a gas leak.
