Questions & Answers

Why does this model start chirping for no reason, about every 10 days. Three chirps, followed by pause, repeats several times -always when we are sleeping. Following instructions I've re-set it, and still happens. Is it trying to tell me something?

                Purchased 4 smoke detectors to replace my existing detectors, great price, features, easy installation and the fact that I won’t have to replace batteries for the next 10 years.

                Easy to install and LOUD, a nice safety feature of EVERY home!
                Easy to install and LOUD alarm, this smoke detector will protect your house and family for 10 years without having to worry about being bothered by the "bip ... bip ... bip" of a low battery. Attaching the wiring (after turning off the red circuit, of course) is easy to do while connecting the yellow lead to the "runner" between all the other hard-wired smoke detectors. Plug the unit in, turn on the power, and (when all the detectors stop complaining that the power went out), press the button and cover your ears. You might even get neighbors coming over to ask if everything is alright! A nice safety feature of EVERY home!

                My Family's safety is first and this helps ensure that!
                Fantastic Smoke detector with a battery backup…I was not aware of a battery backup on a AC hardwired detector, and was pleased to see this. Everything needed to install this detector was in the box, and the instructions were clear and concise. I installed this unit by replacing an existing detector. It was extremely easy. I just replaced the mounting bracket and easily hooked up the wiring. All told, about 15 minutes! The new detector easily twists into the bracket. The unit also has a temporary silence button if needed. The test button released a LOUD audible tone that could wake up anyone! Quick, easy, all parts are included. This is a 10-year detector, with a battery backup!! I will be replacing my other units!

                Nope look for another option
                I was really hoping the first smoke detector was a dud. I reached out and received a replacement and it is going off same as the first. The first one received I noticed on the 3rd day the smoke detector would give off with a very loud warning 3x's then turn off, few minutes later would repeat so I finally disconnected. I was not in my home for a few days so it could have gone off sooner, same as the replacement started going off within a few hours of install

                Quality hard-wired fire and smoke alarm
                This fire and smoke alarm has a lithium back-up battery but must be hard-wired into the ceiling; we gained easy installation access through our attic. Installation instructions were well-written, although the print is very small. Connecting the yellow wire is optional, used to connect with any other hard-wired alarms throughout the house, allowing one to trigger all the others. Once we finished installation, the green "go" light came on, gave the proper test beeps, and is working as expected.

                Easy Install
                This is a generic universal hard wired smoke detector. It came with an instruction manual that was a little difficult to read. It is a very nice looking smoke detector compared to the 20 year old one it replaced. Lucky for me, I did not need instructions to install it. Installation was simple. Much easier than a known brand i installed in another area previously. Once connected the alarm sounded automatically to let you know it worked. Turning it off only required the push of a button. I recommend this product.

                Keeping safe at home
                I hate having to remember to change batteries every time change, so this is a good solution. Came with everything needed to install. Instructions were thorough. I replaced the one in my kitchen area because that is a necessary coverage room. Has a battery backup. When the end of life of detector, it sends an alert. You can interconnect alarms, once one sounds, all compatible devices sound.
