2. SENSITRON A Halma Company DS4847 SMART P-2 Datasheet (EN) P. 2/4 The SMART P-2 gas detector is designed to be installed in car parks and simultaneously detect CO and NO2 gases or CO and petrol vapors. It is compliant with the EN 50545-1 standard, which defines the requirements for the detection of CO and NO2 in car parks and tunnels. For the detection of toxic gases (CO and NO2) the electrochemical cell is used and is housed in the polycarbonate head. The catalytic sensor is used to detect petrol vapors, which guarantees excellent linearity up to 100% LFL. This sensor is placed in an aluminum head, which can be remoted with a maxiumum distance of 1.5m. The EN 50545-1 standard describes the values of the alarm thresholds for CO and NO2, moreover the activation of the alarms is a function of the time- weighted average of the detected gas concentration. The SMART P-2 has a 12-24 Vdc power supply and an RS485 digital signal output. The detectors are housed in polycarbonate enclosures complete with two M20 cable glands.
