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 LEDís (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.
