Replacing RV LP, CO, and Smoke Detectors

One more; inside the dump compartment door.  You’ve got a moment to think as you dump the stink.  What better time to look over your detector expiration dates?  Any compartment door will do.  Find one you frequent, and post this important information there.

All kidding aside, please take a moment to inspect your detectors, find the expiration date, and either write that date down, or replace the detectors, and jot the new detector expiration dates someplace you’ll see it regularly, and remember to check.

Cut, Strip, and Crimp

As someone who has wired about a thousand stereo systems over the past thirty years, cutting and stripping the wire that connected the CO and LP detectors was quite straight forward.


I happened to have my trusty wire stripper with me, which made the process of cutting and stripping the wire even easier.


Given how much wire one finds in a truck camper, a dedicated wire stripper should almost be considered mandatory for anyone who plans to work on their camper.

Of course scissors can both cut the wire, and – if done carefully – cut into the wire insulation to strip the wire.  Either way works, but the dedicated wire stripper sure makes this simple.


Once the CO and LP detector wires were stripped and prepared, we stripped and prepared the wire leads coming from the camper for the corresponding detectors.  The detector ground wires were then twisted with the ground wires from the camper, and fastened with permanent twist-on wire connectors.

Once the new CO and LP detectors were wired up, the next step was to install them back into the positions where the old detectors had been.


The CO detector was identical in shape to the detector it replaced and screwed into position in minutes.  Something this simple, and this critical, is a no brainer for everyone reading this article.  Seriously, please go out and check your CO detector right now.


The LP detector was a bit larger than the detector it replaced and required a bigger hole be cut to install the unit.


Bill Ward took an air tool saw and cut the space bigger to accommodate the new detector.  This could have also been accomplished with a Dremel or small hand saw.


A few minutes later the unit was installed and screwed into place.
