SENSOR TYPE (point 3) shows the gas type detected
by the detector, according to the table below:

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).
