Spectron-804-Exi-H fire flame detector

Presents a fire detector flame infrared (4IC) range. It is made in accordance with the requirements for explosion-protected equipment with the type of explosion protection "intrinsically safe circuit ia", having the level of explosion protection "especially explosion-proof" with the marking RO Ex ia I Ma X / 0Ex ia IIC T6 Ga X / Ex ia IIIC T85ºC Da X according to TR TS 012/2011, GOST 31610.0. The design of the device and the scheme of sensor arrangement allows to obtain the resulting diagram of detection of fire sources in the form of a 90° cone. The signal "FIRE" is formed only when the 4-IR sensors register the presence of flame simultaneously. The standard configuration of the detector includes a relay for the "FIRE" signal and an opto-transmitter for the "FAULT" signal. Provided 4 modes of detector with different thresholds of sensitivity and signal processing time to reduce the impact of interference when the detector identifies the fire or close location of the suspected place of ignition.
