Signature Series Model Edwards Siga-HRS Intelligent Detector-heat gather analog information from their fixed temperature and/or rate-of-rise heat sensing elements. The detector’s onboard microprocessor measures and analyzes these signals. It compares the information to historical readings and time patterns to make an alarm decision. Additionally, digital filters remove signal patterns that are not typical of fires. However, the unwanted alarms are virtually eliminate.
The microprocessor in each detector provides four additional benefits – Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation, and Fast, Stable Communication. The Edwards Siga-HRS Intelligent Detector-heat (fix temperature/rate-of-rise combination) intelligent heat detectors are rate for installation at up to 70 foot (21.3 meters) spacing. In other words, these detectors may be install in rooms with ambient temperatures up to 100 oF (38oC).
The loop controller learns where each device’s serial number address is install relative to other devices on the circuit. Also, this mapping feature provides supervision of each device’s install location to prevent a detector from being reinstalled (after cleaning etc.) in a different location from where it was originally. The history log for the detector remains relevant and intact regardless of its new location. Each detector on the circuit continues to collect and analyze information from its surroundings.
