UR..13. sensors
in an appropriate position in which natural circulation of air is assured, never near
cookers, sinks (water sprays) ventilation grills or windows.
URG13/A
20 - 30 cm from ceiling for the detection of light gases as methane gas, town gas etc.
URG13.P/A
20 - 30 cm from floor for the detection of heavy gases as LPG (butane, propane, etc.).
URO13/A
1.5 - 1.8m from the floor for the detection of Carbon Monoxide (CO).
IN GENERAL:
