About this item

Product details

The Kidde model 10SDR is a battery-operated photoelectric smoke alarm built for a compact, no-wiring setup. Its photoelectric sensor is designed to sense visible fire particles associated with smoldering fires, and the sensor technology is described to help reduce false alarms often caused by cooking or shower steam. Because it runs on 2 AA alkaline batteries that are included in the box, there's no electrical wiring to connect—you simply mount the bracket to the ceiling, then twist and click the alarm into place. Once it's installed, scan the key features below for the alarm and indicator details, weekly testing responsibility, battery and end-of-life alerts, certification information, and warranty terms.
  • Photoelectric sensing: A photoelectric sensor senses visible fire particles associated with smoldering fires, and the sensor technology reduces false alarms often caused by cooking or shower steam.
  • Power and batteries: Operates on 2 AA alkaline batteries, which are included.
  • No-wiring installation: No wiring needed—mount the bracket to the ceiling, then twist and click the alarm into the bracket.
  • Alarm and indicator: Upon sensing smoke or fire, an 85-decibel alarm sounds and a red LED illuminates.
  • Test-Hush control: A Test-Hush button lets you test the alarm and silence nuisance alarms, should they occur.
  • Weekly testing responsibility: 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.
  • Low-battery alert: A low-battery chirp alerts you when the batteries need replacing.
  • End-of-life reminder: The alarm sounds a reminder when it is time to replace the alarm after 10 years of use from its original power-up date.
  • Certifications and standards: UL Certification and ETL Listed; rigorously tested by ETL to meet UL 217 10th Edition and FCC standards.
  • Warranty: 10-year limited manufacturer's warranty that begins when the smoke alarm is powered on. If that date is unknown, assume the alarm should be replaced. The 10-year limited warranty is not a battery performance claim.
  • Compact size: Assembled dimensions of 4.02 in H x 4.02 in W x 1.81 in L.

Small, but really loud. They work really well.

I was kind of nervous when I saw the size of box that two of these came in, but when my husband hooked them up and tested them and we heard the sound they put off we realized that size does not matter. It is loud enough for us to hear from far away. We have one at one towards our room and one by the kids' room. I'm very happy with this purchase. We replaced our much older, much bigger ones for these. I couldn't be happier, plus they come with batteries. What else could you ask for.

Smoke detection safety

As long as a smoke detector is able to alert you to any smoke or changes in your cooking environment, you know they are keeping you safe. I ordered battery operated smoke detectors because they alert me when the batteries are low and in Puerto Rico we have too many electrical outages, when most needed.
