About This Product

Experience the next level of fire safety with the Kidde 10-Year Battery Smoke Detector, Voice Alerts & LED Warning Lights, model 20SD10-V. 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. 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 and voice alerts will state "Fire!" 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
  • Fast alerts - upon sensing smoke or fire, an 85-decibel alarm sounds and a red led will illuminate
  • Voice alerts - crystal-clear voice alerts say fire, when smoke is detected and replace alarm at the end of the alarm's life
  • 10-year never-change battery - no low battery chirps or battery changes for 10 years and saves up to 40 dollars over the life of the detector (10-yr limited warranty on alarm, not a battery performance claim)
  • 3 LED lights - LED lights indicate alarm status, green equals to normal operation, amber equals to operating error, red equals to smoke or carbon monoxide detected
  • Simple installation - no wiring needed, install with the included twist-and-click mounting bracket
  • Self-testing - for added assurance, internal components ensure alarm is always operating as expected (self-testing is not a substitute for a weekly manual push test of the alarm)
  • Test and hush button makes it easy to test the smoke detector and silence false alarms, should they occur
  • End-of-life alarm - alarm sounds as a reminder when it is time to replace the alarm after 10 years of use after its original power-up date
  • 10-year limited warranty
  • Meets requirements of the following authorities - underwriters laboratories (UL), federal housing authority (FHA), housing and urban development (HUD), national fire protection association (NFPA)

    What does the Photoelectric sensor do?
    ByOct 10, 2025
    1 Answer | 
    Answer This Question

    Hello. The photoelectric sensor picks up smoke. It shines two different light and when there is enough smoke that the lights both light up the smoke and the light is reflected to the light sensor, the smoke alarm goes off for smoke.

      My Kidde Model i0910 died. Will this alarm fit on the same mount on the ceiling that my previous one had?
      ByAug 26, 2025
      1 Answer | 
      Answer This Question

      Hello. No, it will have a different bracket and a different placement of the screws. It is exactly for this reason we are transitioning to a universal bracket for most of our alarms so that different alarms won't have different brackets and that future alarms won't have different brackets. We fully admit we had different brackets for different alarms previously.

          When the end-of-life alarm sounds, can it be silenced? It might be several days before the alarm can be replaced. If it can be silenced, does it reset and alarm again after a predetermined period of time? If so, what is that period?

          1 Answer | 
          Answer This Question

          Hello. Yes! Push Test/Hush button once to silence for 24 hrs. (Push Test/Hush button again to clear HushTM and perform a test.) Note: 7 days after End of Unit Life begins, the notifications cannot be silenced.

              Does it come with batteries already in package?
              ByApr 11, 2025
              1 Answer | 
              Answer This Question

              Hello. The batteries are built into the alarm itself on the motherboard. You activate the battery on the back of the alarm or by putting the alarm on the mounting bracket.

                Kidde sealed lithium smoke detector : Is this model i9010? This is the ONLY one wanted
                ByMar 25, 2025
                1 Answer | 
                Answer This Question

                No. The I9010 is not made anymore as it doesn't meet the updated UL code and standards. This is the new version, the 20SD10-V, a 9th edition UL 217 version with photoelectric plus firmware sensor. The I9010 may still be available as the 21008067 if there is any left.

                  Great
                  [This review was collected as part of a promotion.] It's really easy to install. Simple instructions. I have had it up and working for over a month now. Seems to be working great and has no hassle at all. Would definitely buy another one for the other side of the house.

                    Easy installation and setup
                    [This review was collected as part of a promotion.] This smoke alarm is actually very easy to install and seems like it will last for years to come. It has voice alerts and also a guaranteed 10 year sealed battery which is nice to avoid those annoying chirps in the middle of the night. I feel incredibly safe knowing that it is there. The casing of the unit is constructed of hard plastic and feels very solid. It is sleek looking and not terribly big and gaudy looking like some units from the past. Set up is a breeze and it even has the ability to interconnect with other kid units in your home, which is comforting knowing they can be synced up. I would absolutely purchase another. Kidde is a trusted name in smoke alarm and CO2 detectorsane I would recommend to anyone.

                      Good so far
                      [This review was collected as part of a promotion.] I gave this to my husband to test as he would have been a better tester than myself. He uses it in his 3d printing room and has like how it performs so far. It was super easy to install, and the design didn't disrupt the room design. I can't review in detection as we haven't had a real-life situation (he tested it with a fake situation) but overall seems to work reliably.

                        Simple and portable
                        [This review was collected as part of a promotion.] I received this smoke detector complimentary of Influenster in exchange for my honest feedback. I am excited to try this smoke detector in my home. Although we have not had any incidents trigger the alarm, I really appreciate that it has a 10-year battery, voice alerts so you know which smoke detector is alarming, and it just twists onto the holding bracket. Very simple to use - perfect for any home, rental (unscrew it and take it with you when you leave!), or even mobile home / RV.

                          Last for 10years
                          [This review was collected as part of a promotion.] I received this product free from Influenster to try and review. It is the Kiddie Detect Smoke Alarm. I love that you don’t need to change the batteries and that it last for 10 years. No more annoying chirping when the batteries are low.
                          by
                            Will definitely be ordering more of these!
                            [This review was collected as part of a promotion.] LOVE that I don’t need to change the battery in this!!! There is literally nothing I hate more than when the battery is low in my smoke detector and it beeps all day. I have very tall ceilings so it’s difficult to constantly change batteries and with this unit, i only had to put it up once and now I don’t have to think about it for 10 years!

                                    [This review was collected as part of a promotion.] I received this Kidde smoke alarm to review. I love the simple look of this one.
