Kidde 20SD10-CA 10-year battery talking smoke alarm

BedroomMid-range

Safety level: Life-safety alarm: install, test and replace as the maker directs. Follow the manufacturer's placement instructions and your local fire code, test it monthly, and replace it by its end-of-life date.

Warning: Life-safety device: an alarm only helps if it works and you can hear it. Install it where the manufacturer and your local fire code say, check it carries a recognized certification mark (such as CSA, ULC or ETL in Canada, or UL in the US), test it monthly, and replace it when it reaches its end-of-life date. Don't climb a ladder or chair to test it if your balance isn't reliable.

About this product

A battery-powered photoelectric smoke alarm with a sealed 10-year lithium battery, so there is no battery to change for the life of the alarm. Kidde's listing says it announces "Fire! Fire!" as well as sounding an 85 dB alarm, and that it meets the Canadian standard CAN/ULC-S531. It replaces Kidde's older P3010B-CA bedroom alarm.

Brand: Kidde
Typical price (approx.): Approx. C$63 (Amazon.ca, October 2026)

Who it helps

This may help people who find bending down or stretching up hard, for example after hip or back surgery; and people who want everyday tasks to take less effort.

Check before buying

Good for bedrooms and hallways where climbing up to change a battery is the hard part. Test it monthly with the button (many people use a broom handle from the floor rather than a step stool), and replace it 10 years after it was first powered. It is a Canadian model, so US buyers should check for a UL 217 listing.
Check the certification mark, power source, end-of-life date and placement instructions on the manufacturer's page, and what your local fire code requires.
Check return policies in case it doesn't suit you.

Limitations

This is life-safety equipment: it must be placed, tested and replaced as the manufacturer directs. Your local fire department can advise on where alarms are required.
