Fire detectors, thermal, point, explosion-proof, programmable, addressable
The detectors are designed to detect fire accompanied by an increase in temperature in the controlled space and transmit an information digital signal to the control and monitoring device via the standard RS485 communication interface with the Modbus RTU protocol. It is a maximum or maximum differential action detector with a variable response temperature - class "P" according to GOST 34698-2020. The detector measures the temperature of the controlled area in the range from -60 ° C to + 150 ° C. Temperature response classes according to GOST 34698-2020:
| A1 | A2 | A3 | B | C | D |
| A1R | A2R | A3R | BR | CR | DR |
Scope of application – explosion-hazardous areas of premises and outdoor installations according to GOST IEC 60079-14-2013 and other regulatory documents governing the use of electrical equipment in explosion-hazardous areas. It can be used as part of automatic fire extinguishing and fire alarm systems at special-purpose facilities: tanks with oil and oil products; pumping stations of main oil pipelines. The version with an external temperature sensor allows placing the sensor and processing unit in different classes of explosion-hazardous areas.
ATTENTION!
The detectors of the "Azimuth MK (OP) 485" series are not measuring instruments.
Depending on the housing material, explosion protection means and temperature sensor design, the detectors are produced in versions in accordance with Table 1. Table 1
