Kidde Hardwired 120-Volt Smoke Alarm is Inter connectable with other hardwired alarms. The Front battery pull tab allows battery activation without removing alarm from mounting bracket. Large mounting base makes mounting easier, protects surface paint from dirt and covers imperfections. Pre-stripped wiring harness with easy off cap does not require stripper tool. Tinned strands increase conductivity and wire nut grip. Battery run down protection will shut down alarm memory when AC power is not present, reducing low battery chirp. Dust cover protects sensor from contaminates during construction reducing nuisance alarms.

Rated 4.7 out of 5 by 101 reviewers.
Rated 5.0 out of 5.0 by Great product - Easy install Had to replace old smoke detectors that were over 12 years old. I know way past over due !! After looking at reviews and the product myself I decided on this one, glad I did the old ones were a different manufacturer so the plug in was different, but this one came with its own hard wiring, if you needed like me to change plug in. SUPER EASY I had 4 of these units installed in less than 30 minutes... Work great, something as important as smoke detectors I would NOT give a good review if they weren't that good.. They are LOUD also... February 10, 2014
Rated 4.0 out of 5.0 by Better than just run of the mill detectors I never give excellent so the fact that I'm saying good is close enough to excellent. That aside this one has a hush feature that works really nice when you've burnt the toast. Instead of ripping the detector off the wall and hiding it under a pillow simply press the hush button and it mutes the alarm. I'd pay extra for that feature...but didn't have to. April 21, 2015
Rated 5.0 out of 5.0 by Great Smoke Alarm I'm a senior citizen, and I installed this myself with no problem at all. Very simple installation. Good product. I love the battery access door. No more taking the whole unit down just to put in a new battery. February 26, 2015
Rated 5.0 out of 5.0 by Convenient smoke detectors Our handyman recommended these smoke detectors. Said smoke detectors should be replaced every 10 years or so. When I told him I thought the old ones were pathetic--so hard to get off the ceiling and back up there once the batteries were changed, and why on Earth nobody has thought to make one that's easier, he said THEY HAVE--and he recommended Fire-X! He installed them really fast (must not have been too hard to do), and now when a battery needs replacing, we don't have to take the whole thing off the ceiling--you just open a little door on the side of the smoke detector, slide out the old battery, and slide in the new one! Pretty cool! Wish we'd done this years ago. Sure beats standing on top of a big ladder with your arms over your head trying to get the thing off the ceiling and back up again! July 8, 2014
Rated 1.0 out of 5.0 by Defective Product I have had this product installed by electricians and replaced a number of them. They chirp when there is no smoke and the battery has been replaced. This is the last time I will use them. It is hard to find the service manual on line and there are number complaints on line. I will replace all the the ones I have. This is a bad product!

Rated 5.0 out of 5.0 by Easy to install The product installed easily. The instruction were good. I only wish there was a way to recycle/return the unused part(s). March 27, 2015
Rated 5.0 out of 5.0 by Amazing product... The product arrived well packaged, on time and in excellent condition. Very easy to install and worked perfectly as described.Even came with 9-volt battery. Strongly recommend to anyone looking for such product. March 10, 2015
Rated 5.0 out of 5.0 by Easy replacement for existing smoke detectors I replaced six existing smoke detectors with these. Since the original ones had the same electrical connector, replacement was very quick and easy. Look and work great. March 10, 2015
