Edwards EST SIGA-HFS 17/02 Siemens FDOOT441 is an advancedSignature Series Model SIGA HFS and SIGA HRS Intelligent Heat Detectors gather analog information from their fixed temperature and or rate of rise heat sensing elements and converts it into digital signals. The detectors on board microprocessor measures and analyzes these signals. It compares the information to historical readings and time patterns to make an alarm decision. Digital filters remove signal patterns that are not typical of fires.
