Carbon Monoxide Detector Time Expired

[davidpbo]

My CO detector is 7 years old, fitted and activated 2015. It is bibbing so I suspect battery (Lithium) is dead. (Test does not function).

I can change the battery but do the sensors degrade?

It reminded me to check mine. It is a Kidde one and says it has a 10year life from initial power up. The book says it will chirp every 30 seconds when expiry time is reached.

I would expect the sensors to degrade over time, particularly in the humidity of a boat.
If you feel the need to have one, then you might as well get a new one every few years.

It has an electrochemical sensor which will have a limited life. The instructions should tell you the expected life of the sensors.

If yours has a replaceable battery and you are still within the expected life span of the sensor replace the battery and test that it works with a CO source.

It was at the end of its 7 year life. I replaced it despite not having anything in the cabin other than a double burner and grill which is not used unattended, it would have to be blowing old boots for us to have the washboard in while cooking.

For the sake of a few quid, it's a no brainer really. I'd always have at least one on board. Not always what you've got on the boat, it's other people too. Eg - Next door running up a twin engine petrol speed boat could fill you boat with fumes and CO. Or someone running a little genny/pressure washer, etc on the pontoon or even an outboard I guess?

Complete new sensor & display £22 or so from Amazon.

Chirping is a flat battery we had CO an CO2 detectors in our boat engine room and in our sitting room because it has a wood burner, battery changes needed but the sensors have never gone.

Where did you get the CO₂ detector from and why did you fit it ?

How do you know that?

Have you, just as a chance, tried a proven new battery ?

No because I don't have the wherewithal to test the sensor on CO detector and the battery is soldered in Lithium polymer. I could change it easily but decided on a new detector.

The instruction booklet for my CO alarm describes how to put the device into "sensor test mode" and then test it with a lighted cigarette or incense stick.

Following media reports this June about non-working imported carbon monoxide (CO) alarms sold on internet shopping sites, the Boat Safety Scheme (BSS) is cautioning boaters, that choosing the right CO alarm is an especially critical decision as boats can fill in minutes, sometimes seconds, with lethal levels of the highly toxic gas.

My Kidde alarm ( £22 or so from Amazon a couple of years ago ) went off as soon as I cooked a fried breakfast on my boat with the hatches closed, so seems sensitive to both fumes and poor culinary skills.

 

[matthewriches]

Sure it wasn't a combination alarm lol

! might have left it set on Fanny ( Craddock ) alert mode.

Replace the CO detector for less than twenty of your english pounds
