LP and Carbon Monoxide alarms

[kaa4111]

Same subject. Different slant. 1 month old old safe-t-alert that won't stop blinking red/green and making that terrible noise. There is propane and the mute/reset button is not effective. Last night at midnight I took it out of the wall, wrapped it in 3 towels and a couple of hundred bucks worth of duct tape and hung it outside of the trailer. Was afraid to cut the wire because, well...I was afraid. Any ideas until I can get somewhere to have it replaced?

Just returned from a 3 night trip. Each night late, the detector activated. Running the overhead vent took care of it. Only late at night which makes me think that it is a very slow leak somewhere.
We were not using any of the gas appliances. Any suggestions to help me ID the source would be helpful.
Thank you

It's okay to combine smoke and CO detectors. It's not okay to combine LPG and CO detectors. No matter whether that combined LPG/CO detector is on the floor or ceiling, it's still in the wrong place for one of the things it's supposed to detect.

Completely disagree. I have a combined LP/CO detector in my garage that I plug into a wall outlet. It’s very sensitive and all I have to do is start my snowblower inside a very large garage and it immediately goes off. Maybe 5 seconds if that.

Not only that but most of the home CO detectors are plug in to the outlet types for older homes.
