Spectron-801-Exd Series Explosion-proof Flame Detector

Used in hazardous area zones 1 and 2 of enclosed buildings and open installations, as well as in underground mines, mining plants and their above-ground facilities.

Recommended for fire alarm systems and fire extinguishing systems at facilities with UV radiation.

• Housing of Speсtron-801-Exd detector with index "A" is made of aluminum alloy (AD31T5);
• Housing of Speсtron-801-Exd detector with index "N" is made of stainless steel (AISI 321);
• Housing of Speсtron-801-Exd detector with index "M" is made of galvanized steel (steel 10).

Flame detector in stainless steel housing is recommended for use in facilities exposed to acidic, alkaline and other chemically aggressive environments, sea water and salt fog.

Spectron-801-Exd-A, Spectron-801-Exd-M, Spectron-801-Exd-N, Spectron-801-Exd-S-M and Spectron-801-Exd-S-N detectors are equipped with a digital interface supporting the Modbus/RTU protocol.

Spectron-801-Exd-M-HART, Spectron-801-Exd-N-HART, Spectron-801-Exd-S-M-HART, Spectron-801-Exd-S-N-HART detectors are equipped with a digital interface supporting the HART protocol.

For configuring detector’s parameters, “Spectron” configurator program is used. The program allows:

• request the status of the detector;
• restart the detector;
• change additional settings of the detector parameters.

Detectors with “HART” index in the name are configured using HART-USB "Spectron" interface converter. To download the software from our website click this link.

Detectors without “HART” index (with Modbus/RTU digital protocol) are configured using SB-RS-48 interface converter. To download the software from our website click this link.

For facilities with harsh operating conditions, the detector sensitivity can be changed.

The detector heater ensures full operation of the device at an ambient temperature of -70 to +90 ºС. With the heating function disabled the operating temperature range is -55 to +90 ºС. The detector remains operational with a short-term increase in temperature up to +135 ºС.

The field of view of Spectron-804-Exd series is 90º in the vertical, horizontal and all inclined planes.

The flame detection range (in accordance with GOST R 53325): 40 meters to TP5, 40 meters to TP6

Minimal response time, seconds:

The transition of the detector from the Alarm mode to the Normal mode is carried out by disconnecting the power supply for at least 10 seconds

In modifications of Speсtron-801-Exd flame detectors, the index "S" denotes individual adjustment for a specific facility with harsh operating conditions.

ATTENTION. The model of cable glands must be specified when adding to the specification and ordering the equipment. Cable glands are not included in the price of the equipment. Full information on cable glands is available on the CABLE GLAND page of our website . If you have any questions about the correct selection of the type of cable gland, you can contact the technical support service by phone.

Specialized program Spectron-OPS-AutoCAD for easier designing.

The warranty period of is 18 months from the date of commissioning, but not more than 24 months from the date of manufacturing.

Test emitters are offered for checking the functionality and setting:

• IT-12-Exd (black) - a test emitter for remote verification of the detector's performance;
• IT-12-Exd (red) – tuning emitter for remote change of detector parameters.

The range of emitters is 25 meters.

Spectron-801-Exd series flame detector is listed in the MTR “Gazprom” OJSC Stock item identification guide.
