On new residential builds and renovation jobs where code mandates a combination smoke and CO alarm on every level, the Kidde DETECT 21032773 is the hardwired unit professional electricians and contractors specify. A single device handles both threats — photoelectric smoke detection and electrochemical CO sensing — cutting rough-in time and reducing device count on the ceiling. Voice alerts announce "Fire" or "Carbon Monoxide" clearly so occupants know exactly what they're responding to. The unit interconnects with up to 24 compatible Kidde devices, making whole-home interconnection straightforward on residential and light commercial projects. The 120V hardwired connection with AA battery backup maintains protection through power outages, and Smart Hush® lets you silence nuisance alarms on the spot without pulling the unit from the box.
