Caledonia, Mich.– Viking Group, Inc., a Michigan-based manufacturer and distributor of fire protection solutions, is announcing the latest in the innovative flame detector offerings provided in the Alarm & Detection portfolio: the FM Approved VSF303H Multi-Spectrum IR H2 Flame Detector, which can detect hydrogen plume fires at 131 ft.

In addition, the detector offers microprocessor-controlled heated optics that maintain operation in extreme or harsh weather conditions. The FM Approved detector is made of copper-free aluminum or is available in 316 stainless steel.
