The Intelligent Thermal (Heat) Detector Siemens HI921 provides an advanced method of detection, address programming supervision ─ combined with sophisticated FACP communication. Siemens HI921 uses a state-of-the-art thermistor, microprocessor and advanced signal analysis, providing high reliability and accuracy. Additionally, Each Siemens HI921 unit is UL listed including advanced built-in ISOtechnologyTM - a “True Class-X” SLC operation (use is optional) greatly improving system reliability and circuit integrity while providing advanced addressable fault finding. Each Siemens HI921 is a cost-effective, intelligent, addressable thermal detector that provides distinctive, advanced features: seven (7) field-selectable temperature settings specially tailored for application-specific detection needs combined with Class-X SLC operation built-in avoiding additional installation and material cost. The temperature-range settings for each Siemens HI921 detector is between 135°F (57°C) ─ 175°F (79°C) with fixed and rate-of-rise programmability. This variance provides the customer with maximum flexibility to program the temperature settings to suit multiple application needs and changing environmental conditions. Siemens HI921 can be configured to provide a low-temperature warning signal at 40°F (4.4°C). This feature − along with a compatible FACP (Cerberus PRO Modular | FireFinder XLS/V or with Cerberus PRO FC/FV922 or FC/FV924 FACPs) − serves as prevention of water freezing in pipes for sprinkler systems, meeting NFPA 72
