Ceiling mounting is preferred in ordinary residential construction.
For maximum protection we suggest an alarm be installed on each level of a multilevel home including every bedroom, hallways, finished attics and basements. Put alarm at both ends of bedroom hallway or large room if hallway or room is more than 30ft.(9.1m) long. If you have only one alarm, ensure it is placed in the hallway outside of the main sleeping area, or in the main bedroom. Verify the alarm can be heard in all sleeping areas.Ceiling mounting is preferred in ordinary residential construction.

Terrible instructions but great product!
Confusing instructions, but basically after you put batteries in its nearly impossible to see the green light flashing that indicates its on. Had to put my hands over it to block out all the light to know it worked at first. Other than that they work great!
Bryan B –

Everyone needs an alarm.
Why did you pick this product vs others?:I live in a mobile home and both of my alarms had stopped working. They were hooked up to electricity. So I definitely needed a new alarm. After reading about different ones, I decided I liked this one the best.Build quality:It was built for carbon monoxide and fire. I love that idea. I had never had one that was for both. Ease of installation:My son-in-law had it on the wall in no time. Took longer to get his tools ready, than putting it on my wall.Battery life:I put the battery in and I havent had to change it since. So it last a really long timeDesign:I like how it’s made and the way it does the alarm. Value for money:A really good price to have both alarms in one.Size:Same size as my old fire alarm. So it was placed right beside my old one.
