Questions & Answers

Are there a lot of false alarms for the explosive gas component of model KN-COEG-3?

Asked by: SuzyQ
My experience after 2 months of use is NO false alarms....I have located it in a small furnace room that contains both a natural gas furnace and natural gas water heater. As for placing it in the furnace room when the instructions say not to place in furnace rooms--It was my only common sense option in the raised ranch home.-----In any event if i had a gas leak and had placed the detector in an upstairs location or down stairs bedroom far from the furnace and incoming gas lines It may be tooooo late as the gas would never reach the detector in time.... Am I missing something by placing It in the furnace room for earliest possible detection of a gas leak? Agan,I have had NO false alarms and like the units, but you must take time and educate yourself thru the instructions.

why it beeps so often if it shows 0.

Asked by: Esme
Hello Esme, It may be responding to a power spike or fluctuation. It is not an indication of CO or Gas.

We have a Carbon Monoxide and Gas Detector it keeps going off after being plugged in for a day and a half. Reset it it's good for about 36 hrs and it's going off again. Put in a new battery but that has not helped. They are not cheap!! We called the gas Company there was no leaks.
Asked by: 56NOMAD
I wonder if you are having a methane gas leak as this detector will detect that but it isn't natural gas, it could be that your sewer vent is clogged.
