Overview
The Kidde 10SDR is a compact, 4 inch battery powered smoke alarm built for bedrooms, hallways, and other small spaces where a full hardwired system is not practical. It runs on two included AA batteries and needs no electrical wiring at all.
This is a standalone unit, not part of Kidde's interconnected lineup, so it will not signal other alarms in the house if it detects smoke. Its sensing technology is tuned to tell cooking smoke and steam apart from an actual fire, which cuts down on the false alarms battery smoke alarms are known for near a kitchen.
- Two AA batteries included
- Sensing tuned to reduce cooking and steam false alarms
- UL 217 10th Edition and FCC tested
- 10 year limited warranty from purchase date
Who it's for
Good fit for renters, small apartments, guest rooms, or anyone who needs to add alarm coverage to one room without running wire or touching a breaker. Homeowners who want every alarm in the house to sound together should look at Kidde's hardwired, interconnect capable models instead.
Pros and cons
- No wiring or electrician needed
- Compact 4 inch housing fits tight spaces
- 85 dB alarm with visible red LED
- 10 year limited warranty
- Runs on AA batteries, not a sealed long life cell
- Standalone unit, does not interconnect with other alarms
Performance notes
The 10SDR uses Kidde's faster detection sensing to respond to real smoke while filtering out the kind of steam and cooking haze that trips older alarms. When it senses smoke it sounds an 85 decibel alarm and lights a red LED, and the unit is rated to UL 217 10th Edition and FCC standards.
