Description

The Edwards KI-HFD is an intelligent fixed-temperature heat detector that contains a fixed-temperature heat sensor rated at 135 °F. It does not have a rate-of-rise function. The heat sensor monitors the temperature of the air in its surroundings and the detector analyzes the data to determine when the air temperature near the detector exceeds the device’s alarm point.

Besides, the microprocessor in each detector provides additional benefits – Self-diagnostics and History logs, Automatic Device Mapping, and Fast, Stable Communication. Also, the Edwards KI-HFD fixed temperature detector provides a 135°F (57°C) fixed temperature sensor for slow-building fires.

In general, the KI Series smoke detectors bring advanced sensing technology to a practical design that increases efficiency, saves installation 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.

The detector mounting bases accept #18 AWG (0.75mm2), #16 (1.0mm2), #14 AWG (1.5mm2), and #12 AWG (2.5mm²) wire sizes. Sizes #16 AWG (1.0mm2) and #18 AWG (0.75mm2) are preferred for ease of installation.
