I'm going to assume that it is your LP detector that is sounding off...
There are a few reasons that it might be sounding off:
First, is, obviously, a propane leak somewhere in the confines of the trailer. Make sure, first, that it isn't going off because you have a propane leak...that is what it is designed to "sound off" for, a leak, and you definitely want to rule that out first and foremost as the cause. If you've shut the propane off and aired out the trailer and it is still going off, then:
Second, your 12v battery is going low or is failing from an internal short or even an overcharge; any reason that would cause insufficient voltage. Most detectors have circuitry that will warn you when your 12v battery is so low that the detector has not got enough "juice" to effectively monitor for an LP leak (it takes a certain threshold voltage to operate the detection circuitry; much like the "chirp" you get from a smoke detector when the 9v or AA batteries run down). If your trailer has been sitting idle for a month or two and you haven't disconnected it or charged it during that time, your battery is probably low. The LP detector is the primary drain on your 12v battery during storage and will drain your battery in short order. That's why it is a good reason to disconnect your battery if the trailer is going to sit with no provisions for charging it. If your 12v battery is good, there is no propane leak, then:
Thirdly, the device itself has gone bad. That sometimes happens if it gets wet or just shakes its internals loose. They also have a "lifetime", you can usually find a date on them somewhere.
They are wired directly to the battery, however, there may or may not be a fuse anywhere from an in-line type (in an individual wire) to a fuse in your converter's fuse panel that you could pull. If you just want to "shut it up" until you can do adequate testing or until you can replace it (if the cause isn't obvious) you'll find it easiest to unscrew it from its mounting and unplug the unit. Make sure that you get it operational as soon as possible; an LP detector is first line defense against fires in your RV.
