Description
Technical Description – FDS303H
Designed for hazardous industries where fast H2 flames detection is critical and nuisance alarms are not an option.
The MICROPACK FDS303H is an explosion proof multi spectrum IR hydrogen (H2) flame detector. The device delivers superior performance, responding to hydrogen fires at long distances.
The FDS303H has been independently tested to demonstrate it can detect a hydrogen plume fire at 40m (131 ft) in 5 seconds.
A Closer Look
The FDS303H compliments the FDS series of Visual and IR3 Flame Detectors by delivering superior detection performance of hydrogen (H2) fires. The FDS303H utilizes the latest IR flame detection algorithms to ensure maximum false alarm immunity.
The Specs at a Glance
- Multi-spectrum IR design delivers long detection distances and enhanced false alarm immunity.
- Easy integration using industry standard outputs: Alarm and Fault Relays; 0-20mA; HART®, as standard.
- Adjustable sensitivity levels, for application flexibility and to ensure detectors do not cross vote.
- Microprocessor controlled heated optics, maintains operation in harsh weather conditions (snow, ice, condensation).
- Continuous optical test, without a reflector. Verifies operation and improves device up-time.
- Designed to meet performance testing to multiple fuels, FM 3260 and EN 54-10.
On-board Flame Video Recording
Each FDS301 incorporates an on-board Micro-SD card capable of recording 17 seconds of the alarm
video – 8.5 seconds pre-alarm and 8.5 seconds post-alarm. This video recording proves
invaluable during incident analysis and more crucially, you will never have an unknown alarm. This
feature has allowed operators who have experienced fires, to put preventative measures in place to
ensure the same incident does not occur again.
Immunity and Discrimination
Because of its principle of operation, the FDS301 is immune to common sources of unwanted alarms such as hot
work (e.g. grinding and welding), hot CO2 emissions (such as turbine exhausts) and reflected flare radiation.
Single Sensitivity
Unlike any other flame detector on the market, the sensitivity of the detector is preset, and no configuration is required. The detector is sensitive to fires of n-heptane 0.1m2 at up to 44m within a 90° Horizontal field of view. The sensitivity of the detector is pre-set and no changes in sensitivity are required.
Flexible Outputs
With built in relays, the FDS301 can be operated as a standalone alarm device with no need for further control equipment. Alternatively, it can be integrated into a control system using its 2 relay outputs, or a 0 to 20 mA signal with HART.
