I ordered this LP Detector to replace my original LP detector in my RV.
The original was a flush mount CCI Controls PreTell 22 Model # 7770.2. NOTE: There is a large number of CCI LP detectors failing after 4 or 5 years and the company is out of business now. The MTI LP detector mounts just fine in the hole left by the CCI detector. The MTI is slightly shorter then the CCI LP detector but I was able to mount the MTI in the same space with only a slight gap at one end, not really noticeable as my detector is mounted close to the floor.
The MTI detector seems to work just as designed. As a side note, most of the new RV's seem to be using the MTI LP detector.

This was an exact replacement for the CCI Pre Tell 25 LP Gas Detector. It fit into the existing opening and even the screw holes lined up. I just had to cut the two wires off of the old unit and use a couple of crimp connectors to make the connection. Took about 5 minutes to swap it out.

The "Replace" alarm on the propane detector that came with my 10 year old fifth wheel went off while I as getting ready to go on a trip. I searched for that model number and found this matching part. It arrived before my trip and fit perfectly in the hole cutout in the cabinet for the previous detector so installation was easy without any cutting, drilling or the addition of trim pieces. Shipping was fast and the product was just what I needed.

I ordered this LP gas detector as a replacement for the OEM CCI Pre-Tell 21 detector from my 2004 Winnebago Minnie 31C. The RV, new to use, came with a detector that had not been ever replaced - therefore making it 8 years old - which is 3 years past the "replace" date. The first night we camped with the heater, we were jolted awake by the horrific shriek of the CCI detector. There was no leak; it was erroneously sounding - somehow triggered by dust and chemicals that the forced air heat stirred up. We had to silence the alarm every 30-60 minutes, all night long. That made for a *very* long night.

Once I got home, I researched detectors, with the primary goal of an equivalent replacement that would fit nicely in the existing cutout. I was overjoyed to find that this unit fits *perfectly* with no gap or other problem. It was a two-wire connection, and that was that. Even the holes lined up perfectly with the pre-existing screw-holes. Especially for anyone with a Winnebago of about this vintage, looking to replace their flush-mount LP detector, I strongly recommend this unit.

These are really great gas detectors and when one goes out you can't beat this price. The shipment was very fast and we were back to normal in no time.

I took the advice of another review and bought this to replace a unit for our RV. Our original CCI Controls PreTell 22 Model # 7770.2 started activating randomly and after doing research found that it needed to be replaced. It fits into the existing opening so well that it looks original. The only thing we had to do is feed the wires into the old receptacle/plug (or alternatively strip the other half off from the wires in the RV.) Easy to install. Shipping was quick.

Easy installation - one hot wire and one ground wire both clearly labeled, but unit needed a larger mounting plate as the new unit was not as large as the original one. (Thus, hole too large.)Used 1/4" plywood, Works fine, has test button, silent mode too.
