Overview
Kidde built this wired alarm to watch for smoke and carbon monoxide from a single unit, with AA cells carrying it through power cuts. Linked Kidde alarms sound together, and a red light flashes alongside the audible alarm.
Common AA backups mean a dead battery can be swapped from a kitchen drawer rather than replacing the alarm. Owners take on periodic battery changes, and alerts come from sound and a red LED, with no spoken messages listed.
Who it's for
Homes and apartments wired for alarms can tie this unit into a Kidde interconnect run. Someone who never wants to change a battery should look at a version with a built-in long-life backup.
Pros and cons
- Uses common AA backup batteries
- Batteries included in the box
- Two sensors cover smoke and CO
- Interconnects with other Kidde alarms
- Backup batteries need periodic replacement
- No voice alerts described
- Requires hardwired household power
- Interconnect options vary by Kidde model
Performance notes
A photoelectric sensor reads smoke while an electrochemical sensor tracks carbon monoxide, so each hazard has its own detector. Enhanced sensing is meant to filter cooking and steam, which governs nuisance trips near kitchens. Backup runtime during an outage depends on the condition of the AA cells.
