Marine FLAMEVision FV300 Array Based Infrared Flame Detectors

The FlameVision detector utilises infra red 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 FLAMEVision offers a major improvement in both flame detection capability and immunity to false alarm sources over triple IR detectors. It also includes features designed to reduce maintenance requirements.

The FLAMEVision range of detectors provide, as standard, the following system interface:

• Volt-free relay contacts for alarm and fault, programmable as normally open or normally closed
• An analogue output current, in the range 4 to 20mA, proportional to the flame detection signal.
• RS485 serial data port suitable for network connection using a MODBUS protocol.
• Video output compatible with twisted pair video cable.
    

Features:

• Built-in CCTV option to assist with rapid response
• Fast, reliable flame detection using infra red detection
• Simplifies alarm handling for remote control room situations
• Provides immediate visual ID of alarm location
• Robust housing with heated optics
• Automatic monitoring of detector functionality including signal transmission through window status
• 256 infra red sensor array monitoring the field of view to separately identify flame and non flame sources
• Range of integral interface options
• Masking of part of field of view in software configuration tool
• Over 50m detection range with 90° field of view
• Remote video monitoring with fire location and detector information
• Automatic Optical Integrity Monitoring

Benefits:

• Highly sensitive to flame, thus increasing probability of early detection of hydrocarbon fires over a longer range.
• Able to see flames through smoke and through high densities of solvent vapours thus increasing the probability of early detection of hydrocarbon fires.
• Insensitive to artificial light sources, such as halogen lights.
• Consistent, high sensitivity, flame detection throughout a 90° field of view due to 256 individual sensors.
• Consistent detection of different types of hydrocarbon fuels from alcohol to aviation fuel with range or size of fire related to calorific value of the fuel.
• Pinpoint location of the fire within the field of view enabling more effective counter measures to be taken.
• Regular self-testing of critical electronic circuits and regular monitoring of the detector window (OIM) reducing the frequency of regular maintenance visits.
• Integral flame simulation for verification of detection path enabling either easy walk-testing of the installation or testing by remote control to ensure continued reliability of the detector operation.
• Options of different system interfaces as standard.
• Sealed to IP66 and IP67 (when suitable cable gland and sealant are used) ensuring long term reliability in harsh environment.
• Software masking of identified unwanted sources of radiation in the detector field of view.
