*The Alarm Output is an open collector or "contact type" that is CLOSED (on) whenever an alarm is active. The Alarm Output may be set to indicate any one of
various alarm conditions.
** The Valve Override Signal (VOR) is implemented as an analog input which measures the voltage at the input and controls the valve based upon the
measured reading as shown in this section.
