KI-HFD

 Overview 
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.
 The KI-HFD is an intelligent fixed-temperature heat detector that 
contains a fixed-temperature heat sensor rated at 135 °F (57.2 
°C). It does not have a rate-of-rise function. The heat sensor moni
tors 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.
