Answer This Question

I discoved after installing that the center does blink red. It just doesn't have the traditional round bubble LED like my old one did.

              How difficult is it to install this battery powered smoke detector in place of a currently installed battery powered Kidd smoke detector?

              Thank you for your question, you will need to use the mounting backet that comes with this unit. Please follow the installation guide for safety instructions.

              By|Sep 25, 2025

                The main problem you will run into is they decided to make the diameter smaller than a standard smoke detector for some unknown reason, so you will see a paint ring or fading.

                  They are small and easy to install.just a couple of screws. Installed all three in minutes. The best part is that the batteries last 10 years.

                  Very easy install. Met all the specifications for my home fire inspection.

                  Easy to install and hang. Expensive, but I like the peace of mind that the 10-year sealed battery provides—no worrying about changing batteries every year. Definitely recommend!
