Instruction manual

The instrument steps through two screens, showing the units and
gases installed respectively as shown in (FIGURE 2-17) and
(FIGURE 2-18).
If the "Display Alarms" option is enabled, the user is prompted to
decide if they want to view the alarms (FIGURE 2-15).
If the Fresh Air Setup (FAS) feature is enabled, the combustible
and toxic sensors can be zeroed, and the oxygen sensor can be
spanned to 20.8%. FAS must only be used in fresh air. (See
"Fresh Air Setup Option" later in this Chapter for additional
information.)
Fresh Air Set Up Option
(for automatic zero adjustment of the FiveStar Alarm sensors)
NOTE: The Fresh Air setup has limits. If a hazardous level of
gas is present, the FiveStar Alarm ignores the FAS
command and goes into alarm.

WARNING
Do not activate the fresh air setup unless you are certain
you are in fresh, uncontaminated air; otherwise, inaccurate
readings can occur which can falsely indicate that a
hazardous atmosphere is safe. If you have any doubts as
to the quality of the surrounding air, do not use the fresh
air setup feature. Do not use the fresh air setup as a substitute
for daily calibration checks. The calibration check is required
to verify span accuracy. Failure to follow this warning can
result in serious personal injury or death.
