Introduction: Farthermost distance 1000 meters, with the amount of aeriform detector, use wire cable quality of work is relative, source distance can add transmission space through increasing signal amplifier. Stationary gas warning apparatus by call the police controller and detector composition, controller can put park duty room inside, basically undertake controlling to each monitoring point, aeriform detector installs the spot that reveals the most easily at gas, its core component is inside the aeriform sensor of buy, sensor detects the chroma of the gas in air. The aeriform chroma that detector detects sensor is changed into telegraphic date, transmit controller through wire cable, aeriform concentration is higher, telegraphic signal is stronger, be achieved when aeriform chroma or call the police more than controller installs call the police when the dot, aeriform warning apparatus issues alarm signal, can start facility of couplet of substandard of fan of electromagnetism a powerful person, exhaust, eliminate hidden danger automatically. One, the transmission distance of wire cable is the most remote 1000 meters, with the amount of aeriform detector, use wire cable quality of work is relative, source distance can add transmission space through increasing signal amplifier. 2, the output signal of detector has what 3 lines to make: 4-20MA standard signal, second line makes: M-BUS signal or RS485 signal, 4 lines make: RS485 signal, standard RS485 signal 3, 3 lines make commonly used wire cable norms minute of line: Use GB or blame mark RVV3*1 commonly. 0-1.
