Experience the next level of fire safety with the Kidde Hardwired Smoke Detector, 10-Year Battery Backup, Interconnectable, LED Warning Light Indicators, 4 Pack, model 20SA10. This smoke detector has enhanced sensing technology that reduces false alarms often caused by cooking and sends fast alerts that help give your family more time to get out safely. Plus, it is interconnected so when one alarm sounds, they all do so you never miss an emergency (see user guide for compatibility with other Kidde models). This alarm offers a modern 5-inch design ideal for all living spaces such as living rooms, hallways, kitchens, & bedrooms. Comprehensively tested and designed to the latest UL standard for safety and reliability, the 5-inch smoke alarm is powered by 120V AC wiring with a 10-year built-in lithium battery, so you never have to change a battery for the life of the detector (not a battery performance claim). In addition, the detector is self-testing and easy to install with the included twist-and-click mounting bracket. Meets requirements of 9th Edition UL 217, FCC, and CSFM.
DETECTS SMOKE: Sounds a loud 85-decibel alarm when smoke is detected - 3 long beeps with red LED light flashing in time, repeating.
HARDWIRED & 10-YEAR BATTERY BACKUP: Operates on 120V AC wiring (installed in the ceiling). No battery changes for 10 years & saves up to $40 over the life of the detector.
ENHANCED SENSING TECHNOLOGY: Reduces false alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition & FCC standards.
SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.
INTERCONNECT CAPABILITY: When one alarm sounds, they all sound, so you can get out faster. (Different models offer different interconnection options and requirements. See User Guide for more info.)
3 LED NOTIFICATIONS: LED lights indicate alarm status, green = normal operation, amber = operating error, red = smoke detected.
TEST & HUSH BUTTON: Makes it easy to test the 5-inch smoke detector and silence false alarms, should they occur.
10-YEAR WARRANTY: Begins when alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced. (10-yr limited warranty on alarm, not a battery performance claim.)

Title: 10 year backup battery life
Review: AS discribed and easy to install! A huge value at this price! No more buying batteries every fall, as this battery back up last for 10 years. I'm not an electrician and I was able to install so easy and I installed them in a daisy chain (they are all linked so if 1 goes off they all do.) Instructions are easy to understand, and easy to follow. I didn't know that you should replace a smoke detector every 10 years becuase of dedgerdation of the detector, so when these expire it will have saved me lots. I highly recommend this smoke detector and the Kiddie company. The seller packaged them well so they arrived undamaged and in great condition.

Title: Peace of mind
Review: The Kidde Hardwired Smoke Detector is excellent. Installation was straightforward, and the 10-year battery backup offers peace of mind. The interconnectivity feature is a bonus, ensuring all alarms sound if smoke is detected. LED warning lights are clear and helpful. Highly recommend for reliable home safety!

Title: Needed to replace old units
Review: I had bought Kidde 10 year battery smoke detectors in August 2024, and in October 2024, they let me know it was time to replace so I found these. They were easy to install and I was able to buy the wiring harnesses to connect to existing connection plugs. I wish the wiring harnesses were included as part of the item, as I didn't need a separate connector 10 years ago. The 10 year batteries are the way to go as there are no middle of the night chirps with the 6 month battery units. Plug them in and you're good to go for 10 years!

Title: Much better than my last one
Review: I live in an apartment, and my old smoke detector would go off with the slightest smoke. We’re talking eggs would set it off. This guy, I’ve cooked steak with the window cracked and I’ve been fine! Way better at filtering out non issues. Tested and works. No false alarms yet!

Title: Bought 9...2 gave alarms about every week, but only at night...until I disabled them!
Review: Both alarms were removed and thankfully the battery back-up kept them working and alarming even when taken outside (sarcasm intended). Pressing the pause/hush button did nothing! Yes...the other 7 are working fine...so far! Best read the manual completely because you won't have your senses about you when the alarm goes off! Also, beware of putting them in places you can't reach as they advise testing the units every week (totally feasible...sigh). Also, if you need your 8' ladder to press the hush button on the alarm on your 14' ceiling, in the middle of the night...please be careful Also, turning off the breaker doesn't help, they have battery back-ups! I had to disable the alarms to get them to be silenced. I'll see what Kiddie has to say...

Title: Ten-year battery and hard wired into house system make it great.
Review: Easy to install, although it will need to be hooked into the wiring system for the home directly. It does not use our old standard connector plug. We have one unit 17 feet above the floor, and the batteries required changing every six months - a major chore that required our fire company or a handy man to come and do it. No more!
