Overview
A bedroom hallway or a basement near the furnace can get smoke and CO protection from this Kidde alarm without any wiring. Two AA batteries power it, and it chirps when they run low.
No-wiring install puts smoke and CO coverage anywhere a screw can go. Batteries need regular replacement, and the listing describes no voice alerts or interconnect.
Who it's for
Renters and homeowners adding coverage near bedrooms and fuel-burning appliances. Homes that need interconnected alarms or sealed batteries should look at other Kidde models.
Pros and cons
- Smoke and CO in one device
- No wiring needed
- Fewer cooking false alarms
- Mounting hardware included
- Batteries need periodic replacement
- No interconnect described
- No voice alerts listed
Performance notes
Each hazard has its own sensor, so one unit covers smoke and CO in the same spot. Battery life sets how long it runs before the low battery chirp, which the listing does not quantify.
