Det-Tronics X3301
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.
