Page 47: Connection Cable
www.atestgaz.pl Guidelines to the cabling of the system with an RS-485 interface Introductory It is recommended that all system components are made according to the design created by person with the necessary skills and competence. Connection cable The data transmission line for the gas detectors working in the RS-485 standard should be performed only with the use of a shielded twisted pair cable. - Page 48 www.atestgaz.pl Power supply of the gas detector As a standard, in gas detectors with digital data transmission, it is assumed that the voltage cannot drop below 12 V (see the documentation of the detector). The power consumption of the detector is constant within the range of acceptable voltages.
