Quick CO monitor query

Mar 19, 2014 7 Replies

A friend has a failed CO monitor - it chirps and display 'err'. It is not supposed to display this as an 'end of life' warning.



It is a Kidde 900-0146.



I have checked the batteries and they are O.K. (at least it shows the same error with brand new batteries).



Now the destructions say to vacuum once a year and I'm pretty sure this will not have happened.



I will be replacing it anyway but I wondered out of interest if anyone has observed this kind of thing and been able to clear the error.



Cheers

"Move the CO alarm and place in another location prior to performing any of the following:

staining or stripping wood floors or furniture

painting

wall papering

using adhesives

Storing the unit in a plastic bag during the above projects will protect the sensor from permanent damage."

So it is possible to just bork the sensor.

I wonder how many people read and remember this.

The original CO detectors were extremely prone to damage and rarely lasted longer than a year in house with typical usage of household chemicals. They have got a lot better, but are still very prone to being killed by solvent vapours, airosol contents, etc.

They don't half give you a start when they go off ...

I guess that although the alarm might only have sensed 40ppm (or whatever trigger level they use), it's possible that a different room may be at a higher concentration and the occupants already somewhere around crossing the boundary between sleeping and coma.

Certainly not foreign decorators who painted a friend of mines smoke alarm the same colour as the ceiling. Brian

On reflection this also begs the question - what do you do with a mains CO alarm when you are decorating?

If it's like our mains smoke-and-heat alarm set - you press the button on the side and slide it out of its mount.

I also hung on to one of the shower hat things they supplied as new to keep them clean in new houses. We had a total rewire, and it was messy.
