Overview
A photoelectric smoke sensor and an electrochemical carbon monoxide sensor share one housing in this Kidde hardwired alarm. House wiring powers it with battery backup, and interconnection makes linked Kidde alarms sound together.
One device covering both smoldering fires and carbon monoxide saves a second ceiling unit, and interconnection spreads the warning through the house. Dimensions, warranty and service life are missing from the listing.
Who it's for
Homes with an existing hardwired alarm circuit that want smoke and CO coverage at each location get both from one unit. Renters without wired alarm circuits need a battery-only model instead.
Pros and cons
- Smoke and CO in one unit

- Links with many Kidde devices

- Dimensions and warranty not listed
- Needs a hardwired circuit
- No app alerts
Performance notes
The photoelectric sensor responds to visible particles from slow, smoldering fires, while the electrochemical cell detects carbon monoxide. Status shows through LED colors for normal operation, an error or an alarm event. Batteries carry it through power outages.
