UL61010-1 Listed UL, cUL, CE, UL 2075 Recognized Propane/Methane/Hydrogen/Nitrogen Dioxide/Carbon Monoxide sensor
|
|
(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) R134A sensor is factory calibrated to R134A gas but may be used as a general-purpose refrigerant sensor. Sensitivity to some other gases can be found in the installation manual. Actual response may vary depending on installation. For more accurate response to a specific gas, a unit may be field calibrated.
(3) These gases may be detected by the sensor but sensitivity curves are not available at this time.
(4) Carbon Monoxide full scale is 1000 ppm.
(5) Nitrogen Dioxide full scale is 30 ppm.
(6) CO2 sensor is equipped with a heater to account for temperatures down to -40°C.
(7) It is not recommended to de-activate ABC (auto-calibration) except for continuously occupied spaces or greenhouses. Drift ratings may vary based on environment.
(8) 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.
(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.
