The FlameSpec-UV-IR-F flame detector

 

The FlameSpec UV-IR will detect fires and explosions extremely quickly, thereby allowing mitigation steps to be initiated more rapidly to limit event escalation.

Introduction

The FlameSpec-UV-IR-F flame detector provides ultra-fast response, high performance and reliable detection of a large variety of fires including hydrocarbon fires (visible and non- visible). The detector addresses slow growing fires as well as fast eruptions of fire using improved UV-IR technology. The detector operates in all weather and light conditions.

Key Benefits

    • High immunity to false alarm
    • High sensitivity – up to 100 ft. (30m) for a 1 ft2  (0.1m2) n-heptane pan fire.
    • Hydrocarbon flame detection. Spectrum response of IR radiation in the 4.0-5.0 micron range
    • Ultra-fast detection mode detection within 5 milliseconds for fireballs or explosions.
    • High speed (<0.5s) model [X5] available for compliance with NFPA 33.
    • Four sensitivity levels.
    • Universal outputs, 3 and 4 wire, 4-20 mA sink / source, Fire, Auxiliary and Fault Relays. RS485 port using Modbus RTU.
    • Event logger – alarms, faults and 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.
    • Dirty optics warning for preventive maintenance needs.
    • HART® 7, for configuration & maintenance - option available.
    • Window heater to avoid condensation and icing.
    • Stainless  steel tilt mount with horizontal and vertical adjustment.
    • SIL 2 compliant - option available.
    • Detect high UV (sparks and arcs) or IR levels via auxiliary relay and 4-20mA.
