Explosion-proof Flame Detectors series Spectron-600-Exd

Detectors of the Spectron-601-Exd series determine manual arc and argon welding, as false disturbances

They are used in fire alarm and fire extinguishing systems in explosive zones of 1 and 2 classes of enclosed facilities and open installations, as well as in underground mines, mines and their ground structures

Detector in a stainless steel body is recommended for use in facilities, under conditions of acidic, alkaline, etc. chemically aggressive media, sea water and salt fog

Basic version of Spectron-601-Exd-B  is made with a digital output of the standard communication channel RS-485 with support of Modbus / RTU protocol. Current loop 4 ÷ 20 mA with HART protocol support is optional

Spectron-601-Exd-B has separate, galvanically isolated power inputs of the detector power supply and heating system power supply

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 mº

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 Spectron-601-Exd detectors 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

Detector response time is selected by the user from the specified values: 3, 10*, 15, 22 sec.  Manufacturer’s setting of the response time is 10 seconds

Transition of the detector from the "Fire" mode to the "Standby" mode is performed by disconnection for a time not less than:

• 2 seconds for detectors with relay output
• 8 seconds for detectors with HART/Modbus protocol support

S index of modifications of the Spectron-601-Exd flame detectors indicates an individual setting for a specific facility with complicated operatiog conditions
