Description - most recent trouble code logged by the detector 32 possible EST's Signature Series Model SIGA-HFS and SIGA-HRS Intelligent trouble codes may be used to diagnose faults. heat Detectors gather analog information from their fixed temperature and/or rate-of-rise heat sensing elements and converts In the unlikely event that an unwanted alarm does take place, the it into digital signals. The detector's on-board microprocessor control panel's history file can be called up to help isolate the measures and analyzes these signals. It compares the information problem and prevent it from happening again. to historical readings and time patterns to make an alarm decision. Automatic Device Mapping - The loop controller learns where Digital filters remove signal patterns that are not typical of fires.

Each detector has its own unique serial number stored in Installation its on-board memory. The loop controller identifies each device on the circuit and assigns a soft address to that device's serial Signature Series Detectors mount to North American 1-gang number. If desired, Detectors can be addressed using the SIGA- boxes, 3-1/2 inch or 4 inch octagon boxes, and to 4 inch square PRO Signature Program/Service Tool. electrical boxes 1-1/2 inches (38 mm) deep. They mount to European BESA and 1-gang boxes with mm fixing centers. Installation Spacing - The SIGA-HFS (fixed temperature) and the SIGA-HRS (fixed temperature/rate-of-rise combination) Intelligent heat Detectors are rated for installation at up to 70 foot ( meter).

9 Spacing. These Detectors may be installed in rooms with ambient temperatures up to 100oF (38oC). Status LEDs - Twin LEDs are visible from any direction. A flashing GREEN LED shows normal system polling from the loop controller. A flashing RED LED means the detector is in alarm state. Both LEDs on steady shows alarm state - stand-alone mode. Normal GREEN. LED activity is not distracting to building occupants, but can be quickly spotted by a maintenance technician. Quality and Reliability - EST Detectors are manufactured in North America to strict international ISO 9001 standards. All electronics utilize surface mount technology (SMT) for smaller size and greater immunity to RF noise. A conformal coating is used for humidity and corrosion resistance. All critical contacts are gold plated. Compatibility The SIGA-HFS and SIGA-HRS Detectors are compatible only with EST's Signature Loop Controller.
