Other analog inputs include: GAS CONC (point 4) shows the current gas
concentration. SENSOR TEMP (point 11) gives the temperature inside
the detector. RUN TIME (point 12) is the number of days the sensor has
been on.

ALR LO FLAG (Point 90) and ALR HI FLAG (Point 91)
are the main physical DIs on the 901T. They
correspond to a specific gas concentration limit. the low
level, ALR LO FLAG (point 90), is set when the gas
concentration reaches the ALR LO MAX level (point 8),
and cleared when the gas concentration returns under
the ALR LO MIN level (point 7). In the same way, the
high level alarm, ALR HI FLAG (point 91) is set when
the gas concentration reaches the ALR HI MAX level
(point 10) and cleared when the gas concentration is
lower than ALR HI MIN (point 9).
