Propane / CO2 Detectors

I would never use a TT without a working propane/CO alarm. Propane is heavier than air so it needs to be close to the floor. CO is about the same weight as air. It's odorless, aka "the silent killer". You might want to add an extra CO only detector near head hight.

Low DC voltage
Defective Unit
Expired Unit..they have a shelf life. Expiration date is usually stamped on backside


Replace it........be safe!

Our rig is a 2012, I hope they last longer than 3 years....

Kidde makes a CO detector with s ten year lithium ion battery. About $50 at Home Depot

Do you disconnect the battery when you have the trailer parked in storage??

I have a similar problem with a battery powered smoke detector. We have to pull the battery while cooking.

I suppose I will have to replace it or maybe move it farther from the kitchen area.

A dog farting near the detector will also set it off, so if Rover likes to sleep on the floor near the detector, that could be a culprit. I would never sleep in the unit without a detector for gas though, as waking at 4 am is preferable to never waking again.

I agree with you, hopefully they last longer than three years. Since you pulled it try looking at the back and see if there is an expiration date. Also you might try to figure out if the CO or the LP alarm is going off.

Since both alarms need LP to sound you could turn off the gas at the bottles and then light a stove burner and let it burn out. Now turn on the gas only and let it sit that way for the night. If the alarm goes off you know you most likely have a propane leak.

Also when you say it goes off at 4am it makes me think your batteries are draining and setting it off. You might want to find a way to check battery voltage in the middle of the night if the alarm sounds.

I'm always a bit concerned when I read that a CO alarm goes off and the first thing they do is turn off the alarm. Sort of means the alarm is useless of you don't believe it when it goes off. I'd quit fooling around and have it professionally tested so you know when it goes off it's for real.

I agree with Skip. These devices are designed to save your life. Disabling them puts the odds against you when you really need them. I sell gas detection equipment for a living. This isn't something you want to neglect.
