Product details
Kidde Hardwired Photoelectric Smoke Detector Alarm, 10-Year Lithium Sealed Battery Backup
Experience the next level of fire safety with the Kidde Hardwired Photoelectric Smoke Detector Alarm, 10-Year Lithium Sealed Battery Backup, model 20SA10, that uses photoelectric sensor technology to detect visible fire particles associated with smoldering fires. New, 9th Edition sensor technology reduces false alarms often caused by cooking or shower steam, while internal components of the smoke alarm self-test to ensure that it's always operating as expected. (Self-testing is not a substitute for a manual push test of the alarm. Perform a button test once per week to verify proper alarm operation.) The Kidde Smoke Detectors' 5-inch design provides smoke detection for all living spaces such as your basement, living room, bedroom, kitchen, den, bathroom or crawlspace. When smoke or fire is detected, an 85-decibel alarm will sound and a red LED light will illuminate. The Kidde Smoke Alarm is also equipped with 3 LED indicators that illuminate based on the status of smoke alarm: green = normal operations, amber = fault in operation or error, red = smoke or fire indicated. The Kidde Photoelectric Smoke Detector is powered by a 120-Volt AC wire already installed in your ceiling and contains a 3-Volt sealed-in lithium battery (included in the alarm) that lasts the life of the alarm & works as a backup during power outages, providing peace of mind smoke detection. Installation is easy - simply mount the bracket onto the ceiling, pull the wires through the middle of the bracket, connect the wires installed in your ceiling to the Kidde Alarm & twist and click the smoke alarm into the bracket. The Kidde Smoke Detector will chirp when its time to replace the alarm, at the end of its 10-year life span. A test-hush button allows you to test the battery operations as well as silence nuisance alarms, should they occur. This Kidde model smoke alarm also offers Interconnection or Whole-Home Connection, which is the ability to connect alarms, so when one alarm sounds, they all sound, so you never miss an emergency & can escape quickly. Not all models offer interconnection or Whole-Home Connection options and requirements. Check each models user guide for more details. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Listed with a 10-year limited manufacturer's warranty, which begins when the combination smoke & carbon monoxide alarm is powered on. Warranty begins when the smoke alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced. The 10-Year limited warranty is not a battery performance claim. Meets requirements of 9th Edition UL 217, FCC, CSFM, and California Prop 65.

NO BATTERY BEEPS FOR 10 YEARS!!!
As I am in my mid-70s I wanted to forget about replacing batteries in smoke detectors. We have six of them in our home. It's getting more and more dangerous to get up on the ladders. This product with a 10-year battery life fits the bill. However, in my case as I was replacing other smoke detectors I needed a special connector. This was a $5 item and was very easy to install. The connector is made by Kidde also
Verified Purchase
Its Easy!!
The process was a total win. I found the right product at a competitive price with an efficient delivery. The purchase was tracked from acquisition to home delivery. I will use Walmart again.

Peace of Mind for Another 10 Years!
I had to replace my smoke alarms as it had been 10 years since I had installed them. I had purchased Kidde products in the past and have been very satisfied with them. So I purchased 3 of these smoke alarms and had them installed. I watched them being installed and it looked like quite a simple process. Fast and easy and they were in! Now I can have peace of mind for another 10 years!!
