About This Product

Experience the next level of fire safety with the Kidde 10-Year Battery Smoke Detector, LED Warning Lights, model 20SD10. This compact 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. 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 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). When smoke is detected, the red LED light will flash in time with the loud 85-decibel alarm to help you seek safety. A test-hush button allows you to test the battery operations as well as silence nuisance alarms, should they occur. In addition, it's self-testing and easy to install with the included twist-and-click mounting bracket. This Kidde smoke alarm is equipped with an end-of-life notifications that will beep to remind you it's time to replace it at the of its 10-year lifespan. Meets requirements of 9th Edition UL 217 and FCC. Does not meet requirements for CSFM.

Highlights

  • Enhanced sensing technology - reduces false alarms often caused by cooking

    I have the 10 year Kidde smoke alarm that I’ve had for three years. It went off the other day and now I cannot reset it. It’s blinking green light and sometimes red light and chirping. Does this mean it needs to totally be replaced or what?

          Is this model or other Kidde model compatible to GENTEX S1209F "Hardwired Interconnected Photoelectric Smoke Alarm Detector with Dualink, Battery Backup & Relay Contacts"? The GENTEX S1209F Smoke detector is out of stock (or discontinue) from Home Depot.

          Hello. No, Kidde alarms don't work with Gentex alarms and our alarms don't have relay contacts and are not commercially rated.

            Does this use a different mount design than other Kidde detectors like the i9010 sealed 10 yr smoke detector? Can older mounts be used with this one?
            ByDec 29, 2024
            2 Answers | 
            Answer This Question

            Yes! I had to drill two new holes per each new detector. You can't even reuse 1 of the two old holes as the other one will be visible. So annoying. Not even a provision in the bracket to reuse old holes.

              Hello. This alarm uses a different mounting bracket then the older alarms like the I9010 and the mounting bracket will have to be replaced. If you want an alarm with a 10 year sealed battery, you will want the 30CUD10 model 21031514

                From the date of activation most stores only keep them in the shelf for about 6 months

                  The battery warranty is the alarm warranty which is based on date of purchase. You will want to keep a digital copy of the receipt or invoice and/or staple a copy to the owner's manual.

                      Overall an easy to install smoke detector, and I like that is has a sealed battery so there is (hopefully) no worry of the batteries getting low and chirping at what seems like the worst time in the middle of the night. This also saves having to get to a hard to reach location to replace low batteries. The biggest issue I have is that the base plate doesn't have key hole style positions for the screws, like the hardwired versions, and requires you to hold the plate on the ceiling and install the screws through the holes. It would be much easier if you can install the wall anchors and screws ahead of time, slide the plate over them and secure the screws. This is particularly useful when standing at an odd angle on a tall ladder where you want the least amount of fumbling around to get this installed! Why can't they just supply the same base plate as the hardwired versions?

                      Constant trouble beeping
                      We put in four of these. Keep getting trouble alarms We replaced them with the same still get trouble beeping starting to put ones with battery in. Had another one go off at 2 am last night

                        I decided to replace the existing unit in my home because it is located 12 feet high in a vaulted ceiling. Since mid 2018 when I moved in the batteries have failed twice and I need to borrow a 16-foot extension ladder to change the batteries. Kidde's 10-year battery is a great thing for this application. My only negative comment is the fine print suggests you should test the unit monthly. That is never going to happen.

                        Easy to install, but stock is old
                        I ordered today Feb 2025, but received an item manufactured in March 2024. So I already lost 10% of the lifespan of a 10 year product.

                          Not a reliable alarm
                          False alarm too many times. This alarm has gone off multiple times in the middle of the night and won't shut off with a push button. No other alarm does this in the house. For the expense to be safe is important but to be faulty and not able to shut off with a push even going outside is disappointing.

                            The Kidde 10-Year Battery Powered Smoke Detector model 20SD10 Smoke Alarm
                            10-Year Battery Powered Smoke Detector The Kidde 10-Year Battery Powered Smoke Detector model 20SD10 Smoke Alarm is white in color. The indicator flashes Green when in normal standby operational mode, Amber when you have a fault 1-4 times with 3 chirps every 60 seconds, Flashes Red when the Alarm is active. The Smoke Alarm gives you 3 long beeps, repeating until the issue is resolved. Installation is easy with the 2 screws, 2 wall anchors provided with a Philips tip driver. For issues you can find helpful information on the back of the unit. What I like other than the ease of install is that we have not had an alarm go off since installed a week ago Our old unit went off every time the oven door was opened. Must be better calibration not to go off with the oven open.

                            Peace Of Mind
                            I was needing to replace my smoke detector in the basement and wanted a newer model. I like that this one has a ten-year life span and has LED warning. The smoke detector was easy to mount to the wall and set up. The instructions were clear and easy to follow. You only need a Philips screwdriver to do the installation. The dust cover to protect the product was a nice touch.
