Installing Alltronic Centrale Mod. GS200/B Methane Gas Detection System

The objective of the system is to cut off the supply of methane gas by cutting the 230V power supply to a solenoid valve, in this case, the main gas solenoid valve, contrtolled by Alltronic Centrale Mod. GS200/B. The GS200/B central unit can be used with up to 2 GS 12 type gas detectors to cover the entire area to be protected. A 12V DC battery can be integrated. The pre-alarm time can be adjusted from 2 to 60 seconds. The output relay has a double contact (NO and NC) free of voltage, ideal for directly operating a solenoid valve by supplying or cutting off its power.
