Overview
Kidde builds this hardwired combo alarm to speak the hazard out loud, saying Fire for smoke and Warning, Carbon Monoxide for CO. It runs on household power with two AA cells as backup, and linked Kidde units sound together.
Spoken warnings remove guesswork about whether to get out or open windows. The backup uses AA batteries rather than a sealed cell, so it adds a battery chore that sealed models avoid.
Who it's for
Families with gas appliances or attached garages who want clear spoken instructions in an emergency. Homeowners who want zero battery upkeep should consider a sealed battery version.
Pros and cons
- Voice names the hazard
- Smoke and CO in one device
- AA backup batteries included
- Wired interconnect with Kidde units
- Backup batteries need replacing
- Needs existing alarm wiring
- Interconnect limited to Kidde models
Performance notes
Separate sensors handle smoke and CO, and the voice message tells occupants which one tripped. Backup time depends on the AA cells, so fresh batteries matter for outages.
