carbon monoxide detector years image

Shaun B

For ages and ages now we've smelled gas every now and then - we had Transco out who couldnt detect any leaks, but it seems that various times the flue, high up on the outside wall of our house must kick out has because we can smell it.
WE have got a 4 year old combi boiler.
we have got a carbon monoxide detector in the room for safety, but its frustrating..!

is it normal surely we shouldnt be smelling gas though..

its been like this for months

What can I do about a smoke detector than uses batteries very frequently.?

Pikesville

Both ULI and Kidde detectors installed in my house seem to be eating batteries . The ULI detector was manufactured in 2009. The Kidde one in 2010. ULI says it is warranted for 5 years, Kidde for 10 years. Kidde one has suddenly been false alarming carbon monoxide detected when hard wired. Could the hard wiring need to be replaced? My house was built in 1986. Detectors have been replaced several times over the years. The combo carbon monoxide/smoke detectors seem to have more false alarms and are eating up 9 V back up batteries. Help!

Answer
If the voltage is wrong it could be killing the alarms and they are constantly on the battery hence the reason they seem to go through batteries and false alarm.

You could have AC detectors and your home smoke detector circuit is DC (not good).

You could have DC detectors and the power on the line is AC(not good).

Or the voltage could be wrong it may be 120v ac and the detectors are 24vac. (not good)

Sounds to me like it is time to break out the volt meter and do some sleuthing and them go get the right detectors or rewire the detector power circuit in your home.
