EX-PROOF IR/UV FLAME DETECTOR WITH WINDOW DUST LEVEL CONTROL (KZO) AND VIDEO MODULE. SUPER-RESISTANT TO FALSE INTERFERENCE, DOES NOT RESPOND TO WELDING
Super-resistant to heavy optical interference. Determines manual arc and argon welding as false interference
Ex-proofing marking РВExdI / 1ExdIICT6. It is used in fire alarm and fire extinguishing systems in explosive zones of 1 and 2 class of inside facilities and outside installations. Ex-prove mine labeling РВExdI allows detector application in underground mines, pits and surface structures.
Body is made of stainless steel 12Х18Н10Т. Particularly recommended for facilities with complicated operation conditions - exposure to acidic, alkaline or other chemically aggressive media. Exposure to sea water and salt fog
Detector is designed with window dust level control function. When the critical contamination of the viewing window is reached, the detector transmits a fault signal to the computer
Output interfaces for information exchange:
RS-485 with Modbus/RTU protocol support
Current loop 4-20 with HART protocol support
Built-in recorder for 4000 events with the ability to log events of other system devices connected with the detector via RS-485
Additional LED indicators for pre-alarm detection:
blue indicator - UV channel pre-alarm
green indicator - IR channel pre-alarm
On request, the detector can be equipped with a video module for video recording of alarm events.
Additional programmable relay of the detector allows to connect additional equipment to the detector.
Detector sensitivity switching "Far/Near" is provided for facilities with complicated operation conditions. Detection range in the "Far" mode is 25 m, in the "Near" mode is 12 m
Heating of the detector ensures proper operation of the device at ambient temperature from
-70 to +75 ºС. In case the heating of the detector is disabled, temperature range is from -40 to +75 ºС
Viewing angle of the detector remains in a vertical, horizontal and all inclined planes, and corresponds to 90º
Flame detection range corresponds to class 1 according to GOST R 53325-2012 - 25 meters according to TP5 and according to TP6
Minimum response time, seconds
3; 10*; 15; 22
* - manufacturer’s settings)
Mode change of the detector from the "Fire" mode to the "Standby" mode is performed by disconnecting voltage supply for 10 seconds or by a special command using the Modbus / RTU protocol
Protection is made in compliance with IEC 60529:2013
Warranty period 12 years Warranty period could be extended to 36 months if "Warranty extension" option is used.
Detector operates together with ex-proof transmitters:
- IT-12-Exd (black) - test transmitter for remote testing of detector operation availability
- IT-12-Exd (red) - adjusted transmitter for remote modification of detector parameters
Range of transmitters is 25 m.
