Model Tox-4ANA Controller is designed to monitor Tox-ANA series and Tox45-xx series sensors for Carbon Monoxide, Carbon Dioxide, Methane, Propane, Chlorine, etc. or a combination of these sensors. The controller is custom calibrated to turn on ventilation equipment (warning level) and light LED�s (light emitting diodes) to indicate which sensor or sensors are calling for the ventilation equipment to be operated. A second level of operation (alarm level) turns on red LED(s) and sounds an audible alarm (both optional).

The Tox-4ANA is best suited for projects with four or less sensors. For larger projects, see ToxC controller under Product List.
