Explosion-proof, programmable, addressable, heat-sensitive fire detectors
These detectors are designed to detect fires accompanied by a temperature increase in the monitored area and transmit a digital signal to the control panel via a standard RS485 communication interface with the Modbus RTU protocol. They are maximum- or maximum-differential-action detectors with a variable response temperature – class "P" according to GOST 34698-2020. The detector measures the temperature of the monitored 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 |
Applications: Indoor and outdoor hazardous areas in accordance with GOST IEC 60079-14-2013 and other regulatory documents governing the use of electrical equipment in hazardous areas. It can be used in automatic fire extinguishing and fire alarm systems at special-purpose facilities, such as oil and petroleum product storage tanks and main pipeline pumping stations. The version with an external temperature sensor allows the sensor and processing unit to be placed in different hazardous area classes.
ATTENTION!
The detectors of the Azimut 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
