Wiring
Placement
The sensor must be placed 30-50 cm from ground level on a side wall or on a vertical surface. One sensor can cover an area of around 25-50 m2, but the design of the room and the areas where the gas can stop must be taken into account.
Cabling
The sensor must be wired with the necessary cable, for 4-20 mA a minimum 3-core cable, in the case of a relay, the cable required to connect the control is recommended, with a maximum of 8-core cable.
