Micropack launches FDS303 multi-spectrum infrared flame detector

A new multi-spectrum infrared flame detector quickly detects all hydrocarbon fires over a long range, including those not detectable in the visible spectrum.


The FDS303 has been developed by flame detection specialist Micropack for use in hazardous environments where fast fire detection is critical.

In fact, the FDS303 has been independently tested by Factory Mutual to detect a hydrocarbon fuel pan fire at 60m.

“The FDS303 provides excellent immunity to false alarms in hazardous areas. It is explosion-proof and responds to hydrocarbon liquid fuel and gas fires at long distances – up to a range of 60 metres – in less than five seconds,” Director of sales Eliot Sizeland said.

The detector utilises a ‘no-mirror’ continuous optical check, which verifies operation, improves device up-time and needs less cleaning. That – and utilisation of the latest IR flame detection algorithms – ensures a minimum of false alarms and faults.

With microprocessor-controlled heated optics, it’s operating temperature is -60°C to +85°C (-76°F to +185°F), so operation is maintained in harsh weather conditions producing snow, ice, heat or condensation.

The FDS303 comes with global hazardous area approvals FM, ATEX and IECEx and worldwide marine approvals. It has certified performance testing to multiple fuels: FM 3260 and EN 54-10.

Adjustable sensitivity levels give application flexibility and ensure that multiple detectors do not cross-vote.

External testing takes place with a long-range flame simulator that minimises the need for scaffolding. And integration is easy using industry standard outputs; the FDS303 is certified SIL 2 capable.



For over 30 years, Micropack has been actively working with the oil & gas industry and are today recognised as specialists in Fire & Gas hazard detection technologies.

In the early nineteen eighties Micropack was involved in offshore process control and safety systems. This encompassed development, commissioning and support services to major clients and installations such as the Chevron Ninian field.

In the late nineteen eighties, Micropack pioneered the field in optical fire and gas detection technologies and as a result Micropack has been involved in the development of many of the leading detection technologies available on the market today.

Micropack is also experienced in fire research work and the effects of offshore environmental conditions on optical detection methods. This work is what led to Micropack’s development of a range of fire and gas mapping tools to measure the performance of fire and gas detection systems. The company is considered a market leader in this field.

This experience led Micropack to apply its unique specialist knowledge and expertise in its own range of products, including the Visual Flame Detection System. Micropack’s Visual Flame Detection System has been installed and successfully operated globally for over 15 years.
