Q:Can these still be effective if wall mounted?
by|Apr 6, 2024
1 Answer
Answer This Question

A:  Hello. This alarm has to be hardwired in to AC power. If you have a flat ceiling, you can mount it on the wall within a foot of the ceiling. Please see owner's manual and refer to your local fire codes.

        Very simple to replace
        I purchased a 21 year old house and it still had the original smoke detectors, I purchased a 4 pack for the value and it was very easy to replace, this even come with the adapter in case the old ones didn’t have the correct pin configuration. The ready light is very strong and easy to see.

            We're protected again!
            We installed 7 of these to replace old ones that looked just like these (model FADC) and were no longer working properly (false alarms, quiet groan instead of loud siren). The installation included undoing the wire nuts that attached the old wire jumper/connecter and attaching the new wire jumper/connecter with the wire nuts. I was happy to find that the batteries are included. The new ones look nice and make the proper loud siren. I feel like we are protected again!

              This replaces a unit with a sealed (10 yr) battery.. It was challenging to fit the pieces together overhead. This has been in place for just a week.

              HORRIBLE, IVE BEEN TORTURED BY THEM FOR YEARS
              they have literally went off like once a month for years because of low battery. they dont even chirp if its low battery they fully go off and its always at night. i have literally thought there was a fire every single time this has happened but no. THEY ARE SO LOUD THEY MAKE YOUR EARS RING JUST BECAUSE THEY HAVE LOW BATTERY. THEY GO OFF WITH NO WARNING. PLEASE DO NOT BUY!!! (it scared my cat meep too,shes in the photo)

                Junk product IMO.
                We added on to our home in 2020 and City required fire alarms that have wireless networking. These crap alarms go off for no reason, usually in the middle of the night. When one goes off they all go off. It can occur multiple times a day or once every 4-6 weeks. We find no consistency why they go off. Kidde has sent replacements and they still give false alarms. Do not buy!

                  Great pricenpoint on a quality wired smoke detector
                  I like that this model is affordable, has replaceable 9V battery, and has hard wire capability. Its easy to mount with its own mounting bracket. The hardire harness has wires on i e end uou worenut to your house power/ground, and a quick release plug in the detector. Batteries are replaceable from the outside, I installednit and tested it, good to go!

                    Reliable
                    I purchased this as a replacement for the detector in my child’s room. Unfortunately the first one lasted just past the 5 year warranty, so I was stuck buying a new one. Being able to find the exact model made swapping them out very easy. Hoping this one lasts more than 5 years.
