GAS SAFETY WALL-MOUNTED GAS DETECTION CODE Wall-mounted carbon monoxide (CO) and natural gas (CH4) detector The detector can detect two gases: natural gas (CH4) and carbon monoxide (CO) Intervention sensitivity: - natural gas at 10% of the lower explosion limit - carbon monoxide, when the maximum allowed 300ppm CO concentration is exceeded, or rather in case low but damaging concentrations 30ppm for 2 hours persist for long periods in the premises. Power supply 230V a.c. 50-60Hz 2 potential-free changeover contacts output: 5(2)A/250Va.c. Natural gas catalytic sensor Natural gas intervention level...
