Smoke Detector, 10-Year Battery Powered, with LED Status Lights, 85 dB Alarm, 5-inches, 20SD10, 1 Pack

They work. I hate them. Can go off during normal cooking. Triggered by vape. I'm sure if you are an in door smoker it will go off for those too. They are fine as it's only once in a while. 5 star because they do work. Better to be over sensitive than not sensitive enough I guess.

We were getting tired of false-alarm smoke detectors and having them all sing out in unison. Also, getting tired of replacing expensive 9v batteries each year for the 7 of them. This smoke detector has a 10 year battery, loud alarm and easy installation. We opted for the battery only model and tucked the low-voltage wires away underneath the mounting brackets. If the brackets aren't drilled for your wiring box dimensions, they're easily modified with a drill using a small drill bit to drill guide holes and then expanded in diameter with a larger bit to the size needed. Once the base plate is mounted, just turn the detector on the base a quarter turn. The battery is activated with a chirp. A quick button test to make sure it's active. That's it. I'm not a wiz at the mechanics, but the advertisement says that this model reduces false alarms by using traditional as well as visual tech in order to determine an actual fire or smoke danger. So... set it and forget it (with whatever test schedule is right for you) and don't worry about them again until 2035!

Just installed it, so can't comment as to whether it functions as intended, but whoever designed the mounting bracket was either incompetent or a sociopath. Bought this 20SD10 model to replace a Kidde i12060A that lasted 10 months (not years) before it started chirping randomly in the middle of the night, even with a fresh battery. The mounting plate for the prior model does not work with this unit. Perhaps there is a good reason for it. HOWEVER, the holes for the mounting plate are at a different distance from each other than with the prior plate, AND a different distance than the standard ceiling receptacle. Moreover plates like this typically have a larger hole that fits over the head of a bolt that has been slightly unscrewed and can then be twisted so that the bolt can be tightened. This eases installation. This plate requires both bolts to be entirely unscrewed (not a trivial task with a ten-foot ceiling while on a ladder) and then screwed in while the plate is obscuring the bolt holes. The ceiling receptacle has pre-drilled (actually molded) holes that are 2 and 3/4 inches apart and 3 and 1/4 inches apart, as did the prior 2 Kidde detectors. I was able to mount this off-center but wish the Kidde engineers had asked a builder or electrician what might work or at least made a standard mounting plate that fit their entire line of smoke detectors or maybe took a look at some of their prior designs. What could have been a 30 second replacement turned into nearly an hour.

kiddee quality and upgraded looks

Pay attention to what you’re doing when you activate them. The instructions are confusing and ChatGPT is wrong on this one. The center screwdriver type slot in the red dial will line up with the setting you want. It will line up with ON when it’s or will PERMANENTLY DISABLE when you’ve killed it for good. That’s the only thing to be aware of. The instructions can be confusing. When you screw it into the mount, it can only be screwed in clockwise, aka “righty tighty”.

1 of the 3 is already defective after 2 months, it started chirping at 4am giving my dog severe panic attacks, which was the whole reason I bought it so that I wouldn't get low battery alerts all the time. EDIT: Kidde warranty is amazing, after calling them they are mailing a replacement with no hassle.

Very easy to install. We had a Kidde smoke detector for 10 years without changing any battery, so when it started beeping we ordered the same brand, all my husband had to do we twist the old one to remove and twist on the new kidde smoke detector! So easy, he was expecting it to be a pain, it was not and he was thrilled! Will definitely buy again. Arrived on time!

This smoke detector is a great value for the home. The battery lasts for 10 years so no need to replace the battery every 6 months. It is wireless, so you don't need to hard wire it to the electrical system. The accuracy is spot on with no nuisance alarms. It will be a good item to get when you need a replacement detector.

it looks vey good quality
