Overview
Wiring this Kidde combo alarm into an existing hardwired circuit adds both smoke and carbon monoxide detection at one ceiling spot. A sealed backup battery runs it through outages, and linked Kidde units sound together.
Combining smoke and CO sensing with a sealed battery cuts the number of devices and the yearly battery chores. It relies on existing alarm wiring, and interconnect options vary between Kidde models.
Who it's for
Homeowners, landlords and electricians updating wired alarms in homes with gas appliances or attached garages. Homes without alarm wiring need a battery-powered combo instead.
Pros and cons
- Smoke and CO in one device
- Sealed backup battery
- Wired interconnect with Kidde units
- Fewer cooking false alarms
- Needs existing hardwired circuit
- No voice alerts listed
- Interconnect limited to Kidde models
Performance notes
The photoelectric chamber reacts to visible smoke while the electrochemical cell measures carbon monoxide, so each hazard has its own sensor. Placement away from kitchens and steam lowers nuisance alarms.
