D390 Clean Room Flame Detector

3IR FLAME DETECTOR FOR CLEANROOMS & WET BENCHES

Designed for chemical-laden harsh environments, the Model D390 is the most suitable flame detector for semiconductor cleanrooms and wet benches.

The Model D390 is a stand-alone 3IR fire & flame detector in a totally sealed polypropylene enclosure specifically designed for semiconductor clean rooms and wet benches. The D390 detectors is optimized to respond to fire sources from hydrocarbon and non-hydrocarbon fuels while rejecting non-fire false alarm sources. The D390 detectors requires an external 24 VDC power source and is supplied with Alarm / Auxiliary / Fault relays, 4-20 mA Analog and RS485 Modbus outputs. The flame detector is supplied with an integral 10-foot Teflon Coated multi-conductor cable for wiring to external devices. The detector can store 200 events and 6FireGraphs in its FRAM memory.

PRODUCT FEATURES
  • Multi-Spectrum Detection – 3IR design detects flame and fire across multiple spectrums for high false alarm immunity.

  • Versatile Outputs – Alarm, fault, auxiliary relays, 4–20 mA, and RS485 ModBus® for seamless system integration.
  • Event Logging – stores events and 6 FireGraphs for accurate tracking and analysis.

  • Automatic Self-Test – Checks electronic circuitry and Optical Path Integrity test with OptiRadar®Leak-Proof Polypropylene enclosure.

  • Easy Installation – Integral cable harness for easy field wiring, and test mode for manual testing.

  • Made in the USA with a 5-Year Warranty – Built to high standards for long-term reliability.
