Model CMS300 Carbon Monoxide Transmitter and Switch

Current/Voltage Selectable Output, Jumper Selectable SPDT Relay Contact

The Model CMS300 Carbon Monoxide Transmitter and Switch provides a field selectable current or voltage output that is proportional to the carbon monoxide concentration in underground parking garages, vehicle maintenance facilities, or mechanical rooms. An integral relay can be used for alarm conditions and is configured with preset jumper selectable ranges of 25, 60, or 150 PPM. Field calibration can be done by using Model GCK-200CO-2000CO2 calibration gas, Model A-507 calibration adapter, and the on board zero and span potentiometers.

Product Applications

  • Garage or loading dock ventilation
  • Vehicle maintenance facilities
  • Mechanical room monitoring
