Kidde KIR-HD Intelligent Fixed Temperature/Rate-of-Rise Heat Detector

Deliver reliable, fast-response heat detection across commercial facilities with the Kidde Commercial KIR-HD intelligent fixed temperature/rate-of-rise heat detector. Designed for building owners, integrators and security teams, the KIR-HD combines advanced thermistor sensing and continuous self-diagnostics to provide accurate alarm decisions—detecting fires at a 135 °F (57 °C) fixed alarm point or via a programmable 15 °F (8.3 °C)/min rate-of-rise profile for flaming fires. The addressable design supports up to 250 devices per loop and uses existing wiring to lower installation time and cost while enabling centralized monitoring and integration with FX Series intelligent panels. Rotary addressing and non-volatile memory simplify commissioning and maintenance, and the bicolor LED provides instant visual status for on-site personnel. Ideal for commercial security, surveillance, and building fire monitoring applications—warehouses, office buildings, and retail sites—Kidde KIR-HD delivers dependable heat detection where it matters most. Contact your sales representative or add the KIR-HD to your next project for robust heat detection and improved system reliability.

• Faster, more reliable fire detection: intelligent fixed-temperature and programmable rate-of-rise sensing detects both slow smoldering and fast flaming fires to reduce damage and downtime.
• Simplifies installation and maintenance: uses existing wiring, rotary addressing, and compatibility with FX Series panels to cut installation time and labor costs.
• Scalable network performance: supports up to 250 devices per loop and non-volatile memory for dependable, large-scale site monitoring.
• Built for continuous reliability: next-generation thermistor sensing with self-diagnostics and a bicolor status LED for clear on-site indication.
• Flexible mounting and interoperability: ceiling or wall mount with multiple base options (relay, isolator, audible) for integration into security and fire monitoring systems.
