Overview
Mounting this Kidde alarm on a ceiling or wall needs no wiring, since a sealed battery powers it for its full service life. A photoelectric sensor watches for smoke, and the alarm sounds, flashes red and announces the hazard by voice.
No battery swaps and no chirps for the life of the unit make it easy to install in every bedroom and hallway. The listing describes no interconnect, so each unit only warns the room it is in.
Who it's for
Renters, landlords and homeowners filling gaps in bedrooms, halls and apartments. Homes where every alarm must sound together need an interconnected system.
Pros and cons
- Sealed battery, no swaps
- No low battery chirps
- Voice alert announces the hazard
- Fewer cooking false alarms
- No interconnect described
- Smoke only, no CO detection
- Whole unit is replaced at end of life
Performance notes
A photoelectric sensor reacts to visible smoke particles, which suits slow smoldering fires. Placement away from steam and cooking reduces nuisance alarms further.
