General Monitors® FL500-H2 UV/IR Flame Detector

General Monitors® FL500-H2 UV/IR Flame Detector

Product catalog summary
Overview: The General Monitors FL500-H2 is a UV/IR flame detector designed for detecting hydrogen fires. It combines ultraviolet (UV) and infrared (IR) sensors to provide quick response and increased immunity to false alarms, suitable for both indoor and outdoor environments.
Design and Features: The detector features a rugged stainless steel housing, three LED status indicators for alarm, fault, and normal conditions, and a reduced footprint for easy installation and maintenance. It includes a self-check feature called Continuous Optical Path Monitoring (COPM) that performs regular checks to ensure functionality.
Performance and Testing: The FL500-H2 is Factory Mutual (FM) approved for hydrogen fires and can be tested using the TL105 Test Lamp, which simulates fire conditions without the risk of an open flame.
Specifications:
  • Wavelengths: UV: 185 to 260 nm, IR: 2.95 microns
  • Field of View: Up to 130° conical
  • Response Time: Less than 3 seconds for hydrogen at 60 ft.
  • Classification: Suitable for various hazardous locations (Class I, Div 1, Groups B, C, D, etc.)
  • Approvals: CSA, FM, ATEX, IECEx, INMETRO, CE Marking
  • Power Requirements: 20-36 VDC, 200 mA max.
  • Analog Output: 0-20 mA with various signal levels for fault, ready, IR, UV, and alarm conditions
  • Relay Contact Rating: 5 A at 250 VAC or 30 VDC
  • Communication: RS-485 Modbus RTU, HART 7 compliant
  • Environmental: Operating temperature range from -67°F to +185°F, humidity 0% to 95% RH non-condensing

General Monitors® FL500-H2 UV/IR Flame Detector-1

General Monitors® FL500-H2 UV/IR Flame Detector Self-check feature Rugged stainless steel enclosure UV detector Three LED status indicators for alarm, fault, and normal operating conditions UV/IR TECHNOLOGY SAFETY INTEGRITY SELF-CHECK A UV/IR flame detector combines an ultraviolet (UV) sensor for quick response and an infrared (IR) sensor that monitors radiation emitted by a hydrogen flame. This combination offers increased immunity, operates at faster speeds and is suited for both indoor and outdoor use. Every two minutes, a built in self-check known as Continuous Optical Path Monitoring (COPM) performs an optical and electrical check to ensure the optical path is clear and the electronic circuitry is operational. IMPROVED DESIGN RELIABLE TESTING ANYTIME, ANYWHERE Stainless steel housing, three LED status indicators, reduced footprint, and simplified wiring make the FL500 Flame Detector easy to install and maintain. The FL500 Flame Detector can be tested with our exclusive TL105 Test Lamp, which simulates the flickering of a fire. This allows the detector to be tested under simulated fire conditions without the associated risk of an open flame. FM PERFORMANCE APPROVED DETECTION The FL500-H2 Flame Detector is performance approved by Factory Mutual (FM) for hydrogen fires.
