UL61010-1 Listed UL, cUL, CE, UL2075 Recognized CO and NO2 elements
|
|
(1) One side of transformer secondary is connected to signal common. Dedicated transformer is recommended. No mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certified by a national or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required.
(2) Carbon Monoxide full scale is 1000ppm.
(3) Nitrogen Dioxide full scale is 30ppm.
(4) Accuracy of CO2 reading may be reduced at temperatures below 14ºF (-10°C). CO2 sensor is equipped with a heater to account for temperatures down to -40°C.
(5) It is not recommended to de-activate ABC (auto-calibration) except for continuously occoupied spaces or greenhouses. Drift ratings may vary based on environment.
(6) Combination CO/Methane, Co/Propane, or CO/Refrigerant sensors should be mounted according to Propane/Methane/Refrigerant recommendations. Consult factory for other combinations. Mounting height recommendations may be adjusted according to installation. Ensure sensor is accessible for maintenance and target gas has unobstructed access to sensor. Mount in accordance with ANSI/NFPA 70 and NEC or CEC.
(7) R134A sensor may be used as a general purpose refrigerant detection. The sensor's response to other refrigerants will change proportionally as shown in the following app note: https://www.senvainc.com/catalog/documents/downloadcenter/Refrigerant%20cross%20sensitivities.pdf Actual response may vary depending on installation. For more accurate response to a specific gas, a unit may be field calibrated.
(8) These gases may be detected by the sensor but sensitivity curves are not available at this time.
(9) A bump test involves exposing the sensor to a reference gas and detecting the sensor’s response. If sensor response is out of accuracy range, recalibration or replacement of the sensor element may be necessary.
