Spectron-701-Exd Series Explosion-proof Flame Detector

Can be 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 using in fire alarm and fire extinguishing systems in the facilities with UV radiation sources.

• Housing material of Spectron-701-Exd with index "A" is aluminum alloy (AD31T5);
• Housing material of Spectron-701-Exd with index "N" is stainless steel (AISI 321);
• Housing material of Spectron-701-Exd with index "M" is 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.

For facilities with harsh operating conditions detector’s sensitivity range can be switched

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

The field of view of the detector is 90º in the vertical, horizontal and all inclined planes.

The flame detection range is (according to GOST R 53325): TP-5 - 30 meters, TP-6 - 30 meters.

Minimal response time, seconds: 3, 5, 10, 15

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

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 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.
