The VSF303 is an explosion-proof multi-spectrum IR flame detector. The device delivers superior performance, responding to hydrocarbon liquid fuel and gas fires at long distances. The VSF303 has been tested by FM to detect a hydrocarbon fuel pan fire at 200 ft. (60 meters) within five seconds!

Its multi-spectrum IR design delivers long detection distances and enhanced false alarm immunity. Plus, with continuous optical testing (without a reflector), the VSF303 verifies operation and improves device up-time. Its microprocessor-controlled heated-optics maintains operation in harsh weather conditions such as snow, ice, condensation and more. With simple integration, adjustable sensitivity levels and so much more to offer, the VSF303 Multi-Spectrum IR Flame Detector delivers the high-quality performance needed to ensure top-of-the-line detection capabilities.
