Kidde KIR-HCD Intelligent Multisensor Heat and CO Detector

Protect occupants and assets with a single, intelligent device: the Kidde Commercial KIR-HCD multisensor heat and CO detector delivers combined fire and carbon monoxide monitoring for demanding commercial environments. As a Kidde KIR Series combination detector, the KIR-HCD pairs rate-of-rise heat sensing with an electrochemical CO sensor to detect both smoldering and fast flaming fires while continuously monitoring for invisible CO threats. Built for security and building systems, it supports up to 250 addresses per loop and operates on DC power (15.20V–19.95V DC), and is UL 268 listed for dependable code compliance. The detector’s on-board microprocessor analyzes analog sensor data, applies digital filtering and automatic environmental compensation to minimize nuisance alarms and reduce maintenance. Installation teams benefit from rotary addressing, automatic device mapping and compatibility with existing wiring to speed deployment across campuses, hospitals, schools and commercial sites. Ideal for integrated security, surveillance and life-safety monitoring solutions — specify the Kidde KIR-HCD for a reliable, low-maintenance multisensor detector and contact your distributor to add it to your next project.

• Dual hazard protection: combines rate-of-rise heat sensing and carbon monoxide monitoring to reduce device count and simplify life-safety coverage.
• Fewer nuisance alarms: on-board digital processing and environmental compensation filter non-fire signals for reliable, actionable alarms.
• Faster installations: uses existing wiring and rotary addressing with automatic device mapping to cut commissioning time and labor costs.
• Code-ready reliability: UL 268 listing, continuous self-diagnostics and non-volatile memory help meet compliance and reduce maintenance overhead.
• Scalable integration: supports up to 250 addresses per loop for flexible deployment in commercial, institutional, and multi-site security systems.
