Kidde CO120X Relay Module for I-Combo Units, CO Alarms

Ensure rapid, coordinated notification when carbon monoxide is present by adding auxiliary alerting to your life-safety network. The Kidde Residential CO120X Relay Module is a compact relay designed to activate external bells, sirens, hallway or stairway lighting when it receives a CO interconnect signal from compatible I-Combo carbon monoxide alarms. Because the relay only energizes on CO signals and will deactivate if it receives a smoke interconnect, installations benefit from precise, reliable behavior that reduces nuisance activations and supports integrated alarm control systems.

Engineered for easy integration into security, monitoring and surveillance-focused installations, this US-made relay (Manufacturer P/N: CO120X) fits tight spaces at 3/4" x 3" x 1-3/4" and weighs just 0.15 lbs, making it practical for retrofits and new construction alike. Use it to extend CO detection to remote notification devices, improve site-wide alerting strategies, and strengthen overall fire and gas safety procedures. Add the Kidde CO120X to your system to enhance monitoring reliability and occupant protection—order now or consult your Kidde supplier for integration guidance.
