Propane / CO2 Detectors

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.

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 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.

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

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

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


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

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.
