- Local control: Kidde doesn't say whether the alarm works without the cloud.
- Detects: The page gives no UL standard.
- Power: Kidde says 120 V AC with a lithium backup battery; it calls the 10-year figure a warranty term, not a battery performance claim.
- Alarms link wirelessly: No wireless interconnect: it links by wire only to Kidde alarms with hardwired AC interconnect, and then when one sounds, all sound.
