Safe-T-Alert 20-441-P-WT Mini Hard-Wired Propane/LP Gas Alarm - 12V, 20 Series, White

It was for our R.V. propane detector dated to last 5 years . this one was already 1&1/2 year old.

Perfect replacement. Won’t give 5 stars too early we’ll see what life is.

This was a perfect match for the one In our camper

Perfect replacement for original one. The manufacturing date (is on the back of unit) is very important. Although these are wired they do have a battery in them. There’s no replacing the battery, the whole unit needs to be replaced when the battery dies. Most brands including this one have a five year battery. Once you open, check the date to ensure that it was recently manufactured. If it isn’t recent, return it. Saw one at a local Camping World before buying this one. Had them open for me (used to be able to see the manufacturing date but the packaging has changed and you can’t see it. Guess what, it had been manufactured two years ago. So that meant two years of lost battery time. HINT: Do yourself a favor and put manufacturing date on side or top of unit (with permanent marker) where it can easily be seen when replacing your current unit. That way you’ll know when it is close to time to replace. Since the manufacturing date is on the back, you can’t see it without removing whole unit from wall. No wondering “when did we replace it”.

Easy install

Excellent replacement for existing, easy to install, and worked immediately upon energizine.

Works good. Time will tell. Very easy to install with two screws and two wires.

exact replacement for the one that lasted 9 years in my RV, easy to install, took 5 minutes
