The FlameSpec-IR3-H2-HD flame detector

FlameSpec IR3-H2-HD offers the fastest detection of flames and explosions, providing extra time that can be used to reduce damage to plant & property and evacuation of people.

Introduction

The FlameSpec-IR3-H2-HD flame detector provides unrivaled response, high performance and reliable detection for a number of fires found in Energy Transition applications. The detector addresses slow growing fires as well as fast eruptions of fire using improved IR3 technology. The detector operates in all weathers and light conditions.

The detector provides high-definition (HD) video output of the monitored area with near IR filtered imaging of fire events and personnel at distances up to 100 ft. (30m). This allows the rescue team to be aware of the exact situation before entering the hazardous area.

Video and data of events are stored saved quickly to non-volatile memory for post incident investigation. The recordings start one minute before detection and continue for up to four minutes.

Key Benefits

    • High immunity to false alarm, including arc welding.
    • Detects, hydrogen, ammonia, methane & syngas flames using three infrared wavelengths, with clear separation.
    • Each sensor has the same field of view to further improve false alarm immunity. HD, or composite, video output with automatic HD video recording of events.
    • Ultra-fast detection mode detection within 40 milliseconds for fireballs or explosions.
    • High speed (< 0.5 s) model [X5] available for the detection of fires in enclosed spaces.
    • 5 selectable sensitivity levels.
    • Data/Event logger – alarms, faults & videos as well as other relevant events are logged to non-volatile memory.
    • Built-in-Test (BIT) – Automatic and manual self-test of window cleanliness and overall detector operation.
    • Universal outputs, 3 and 4 wire, 4-20 mA sink / source, Fire, Auxiliary and Fault Relays. RS485 port using Modbus RTU.
    • HART® 7, for configuration & maintenance - option available.
    • Dirty optics warning for preventive maintenance needs.
    • Heated window to avoid condensation and icing.
    • Stainless steel tilt mount with horizontal and vertical adjustment.
    • SIL 2 capable - option available.
