Spectron-804-M-Modbus fire flame detector

Spectron-804 series detectors are ultra-highly resistant to heavy optical interference. Detect manual arc and argon welding as false interference They are recommended for use in fire alarm systems and fire extinguishing systems in closed objects and open installations. The detector housing is made of galvanised steel. For objects with difficult operating conditions there is a switchable sensitivity of the detector, 4 operating modes with different range and time of flame detection. The viewing angle is maintained in vertical, horizontal and all inclined planes, and corresponds to 90º. Transition from the detector from the "Fire" mode to the "Duty" mode is made by removing the power for at least 2 sec.
