KI-HRD
The KI Series smoke detectors bring advanced sensing technol ogy to a practical design that increases efficiency, saves installa tion time, cuts costs, and extends property protection capabilities. Continuous self-diagnostics ensure reliability over the long-haul, while the latest thermister technology makes these detectors ideal wherever dependable heat detection is required.
Overview
The KI-HRD is an intelligent fixed temperature/rate-of-rise fire detector. It monitors the temperature of the surrounding air and analyzes the data from the sensor to determine whether to initiate an alarm. The rate-of-rise heat function quickly detects a fast, f laming fire. The fixed-temperature heat function detects fire when the air temperature near the detector exceeds the alarm point.
