“Most reliable” array-based infrared flame detection device

Current flame detection technologies have drawbacks: UV/IR detectors have good false alarm immunity, but limited detection range, high power consumption and problems if the field of view is obstructed by mist or smoke. Single IR detectors can only offer a compromise between detection sensitivity and blackbody rejection. Triple IR detectors achieve long range detection but sensitivity is significantly reduced in the presence of blackbody sources. The continued search for sensitive and reliable flame detection with false alarm immunity has resulted in the “revolutionary” FlameVision FV300.Traditional flame detection solutions have a wide range and deep field of view. This means when there is an alarm, the fire could be anywhere in a large area, possibly requiring staff to physically investigate, with the resultant time and safety implications. FlameVision pinpoints the location of the alarm incident(s) immediately so that the right decision can be made.

The FV300 makes many more calculations and analysis actions than any previous flame detector type, providing reliable detection. Comprehensive self-test routines of sensors and electronics along with reporting of optical integrity ensure reduced spend on unnecessary maintenance. The FV300 features interfaces for 4mA to 20mA, relay and MODBUS to meet demands for integration to non fire panel controls.

The detector utilizes infrared array based flame detection combined with integral CCTV to automatically and reliably identify flame incidents and pin point the location on a video image. By using an array as the sensing component, the FlameVision detectors are able to locate the angular position of the fire within the field of view. The detectors use this information to provide superimposed location information on a composite video output from an internal CCTV camera and to signal the coordinates of this location on its data output. This information allows the operator to quickly verify the alarm and implement the necessary actions. It also provides a valuable tool for false alarm control and event audit processes.

The device features 256 infra red sensor array monitoring the field of view to separately identify flame and non-flame sources. It enables over 50m detection range with 90° field of view. Regular self-testing of critical electronic circuits and regular monitoring of the detector window (OIM) reducing the frequency of regular maintenance visits. It is sealed to IP66 and IP67 (when suitable cable gland and sealant are used), ensuring long term reliability in harsh environment.
