When code requires a combination smoke and CO alarm on every level of a new build or renovation, the Kidde DETECT 21032773 is the hardwired unit contractors reach for. Photoelectric smoke detection and electrochemical CO sensing are combined in a single device, cutting installation time and reducing the number of devices to rough-in. Voice alerts announce "Fire" or "Carbon Monoxide" clearly — no guessing during an emergency. It interconnects with up to 24 Kidde devices so when one sounds, they all sound, making it straightforward to meet whole-home interconnection requirements on residential and light commercial jobs. The 120V hardwired connection with AA battery backup keeps protection live through power outages, and the Smart Hush® feature lets you silence nuisance alarms without pulling the unit.
