Flame Detection

  • FGard IR3 (SIL-2)

    The Crowcon FGard IR3 flame detector is an explosion proof multi spectrum IR flame detector. FGard delivers superior performance, responding to hydrocarbon liquid fuel and gas fires at long distances.

    The FGard IR3 delivers first-in-class flame detection with intelligent heated optics for clearer results and advanced optical verification to greatly reduce false alarms.

    60 metre flame detection range – Will detect all Hydrocarbon fires which means no condensation forming on the window, improving reliability and performance across temperature.

    Responds in less than 5 seconds to 0.1m² fire at 60 metres

    Intelligent heated optics – No condensation / ice / water

    Automatic test verifies cleanliness of the lens and electronic circuitry. No reflector optical check and large optical surface results in far fewer false alarms.

Gas Detection Control Panel

  • Gasmaster

    Crowcon’s enhanced Gasmaster gas detector control panel has a modular design meaning users only need purchase the required number of input modules. It can easily be extended by adding more modules at a later date.

    All gas levels are displayed simultaneously – enables full systems status check at a glance.

    Alarm messages can be customised to indicate the name or location of any detector in alarm.

    All functions, from day-to-day operation to re-calibration, can be carried out from the front panel – routine testing can be performed rapidly.
