HI921 Thermal (Heat) Detector

Model HI921

The Intelligent Thermal (Heat) Detector (Model HI921) provides an advanced method of detection, address programming supervision ─ combined with sophisticated FACP communication. Model HI921 uses a state-of-the-art thermistor, microprocessor and advanced signal analysis, providing high reliability and accuracy.

Additionally, Model HI921 is a cost-effective, two-wire / addressable thermal detector that provides a distinctive, advanced feature: seven (7) field-selectable temperature settings specially tailored for application-specific detection needs.

  • Compatible with Siemens Model `H’-series devices on the same loop (with Cerberus PRO Modular | FireFinder XLS/V | FC9–series fire-alarm control panels)
  • Contains seven (7) field-selectable settings in a temperature range of 135°F –174°F (57.2°C –78.9°C)
  • Provides a low-temperature warning of 40°F (4.4°C)
  • Field programmable as rate-of-rise or fixed temperature
  • Tri-color detector-status light-emitting diode (LED) with 360 ° view
  • Compatible with Model 8720 | DPU (device programmer / loop tester)
  • Utilizes advanced, microprocessor-based signal processing
  • Each detector is self-testing:
    -complete diagnostics performed every 10 seconds
  • Polarity insensitive via SureWire™ technology
  • Functions with Model DB-11–series mounting bases
  • Superior electromagnetic interference (EMI) and radio-frequency interference (RFI) immunity
  • Restriction of Hazardous Substances (RoHS compliant)
  • UL 521 Listed, ULC Listed; FM (#3230,#3210), CSFM (#7272-0067:0258) Approved
