Question: where on the wall to install it
Document: I was surprised to read the instructions. They stated clearly that this alarm should be mounted low in the wall.
Perfect for our rv. Set right into the original on the wall, tested perfect, easy replacement. Everyone should have one in their rv.
We've only had the thing for about 2 months. My husband just put it together and mounted it on the wall a few weeks ago, so it should be in tip top shape!
I had to replace an old CO Alarm in my RV and found this exact replacement at Amazon. It fit perfectly in the original wall-mount holder that I had removed the old one from. Perfect!
Easy to install, went up in minutes, came with batteries and clear instructions.
Easy to install, light tells if it is working, good value for price.
My old one went past its life of 5 years and I wanted to replace it with the same model which I could not find anywhere else. It is a very efficient product and I did not have to make a new place for it to fit on my wall.
Seller was terrific. Low price, fast delivery and reasonable shipping.Product is easy to install.
I would recommend this product. It was very easy to install and half the cost of the same product at RV dealerships.
This is the second one of these we have purchased. The first one lasted well over 10 years before it finally gave out. This one fit right where the previous one had been, saving me the problems of putting new screws in the wall, etc. Compact and easy to change batteries.
Answer: yes
