Honeywell FS20X Flame Detector

Feature & Principle

It is a multi-spectrum flame detector of Honeywell Fire Sentry FS20X series, integrating UV, dual IR and visible light sensors. It adopts double microprocessor and frequency analysis algorithm to identify flame characteristics and suppress false alarms. The detection range can reach over 60 meters for 0.1m² heptane fire. It supports adjustable sensitivity and continuous self-diagnosis. When the lens is contaminated or smoke is heavy, the infrared and visible channels can still maintain detection capability. It outputs alarm and fault signals via relay or Modbus communication for fire & gas safety system interlock.
