Operation Overview
Once installed and power is turned on, the VOXI runs continuously to measure VOCs, display
the concentration readout and any alarms (flashing LEDs), and send any output and alarm signals
connected to external devices. The pump runs intermittently when VOCs are below 500 ppb, in
order to extend the life of the filters and the pump itself, but runs continuously above this
threshold. The VOXI has an on-board heater which turns on at low temperature to reduce the
possibility of condensation in the PID sensor. Both the VOC threshold and temperature threshold
are set at the factory and cannot be adjusted by the user. Other operating parameters are set with
the controller.

Controller Operations
5.1 Hardware and Software Requirements
An external mobile phone or tablet is required as a controller to program operating parameters.
Currently Android 6.0 or higher platforms are supported. Updating to the latest Android version
is common practice and recommended. Use an Ex (Intrinsically safe) Android device if operating
in hazardous environments. Operation requires the mPower Suite Android App. If not already
installed, it can be downloaded at
