Description

The Edwards SIGA-HFD is an intelligent fixed-temperature heat detector that features a fixed-temperature heat sensor rated at 135°F (57.2°C). Also, 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.

Edwards SIGA-HFD – The Signature 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 microprocessor in each detector provides additional benefits, including self–diagnostics and a History Log, Automatic Device Mapping, and fast, Stable Communication.

Additionally, each Signature Series detector constantly runs self-checks to provide important maintenance information. Furthermore. The results of self-checks are automatically updated and permanently stored in the detector’s non-volatile memory.
