The X3301 Multispectrum IR Flame Detector uses signal processing algorithms, supported by an embedded 32-bit microprocessor, to provide continuous protection in the presence of false alarm sources where hydrocarbon fires and infrared radiation may occur. It is suitable for indoor and outdoor applications that require the highest level of false alarm rejection and fire detection performance. The detector is available in aluminum (painted) or stainless steel (316/CF8M cast) for installation in the harshest environments.

The X3301 has a detection range to a 1x1 foot (0.3 x 0.3 m) n-Heptane fire at 210 feet, and a solid cone of vision for methane fire. The detector features standard fire alarm, fault and auxiliary relays, with an isolated 0 to 20 mA output model with optional HART communication. The X3301 provides superior performance in applications that are at the extremes, and where background infrared radiation is a normal condition.
