Oxygen Measurements
The FiveStar Alarm detects the amount of oxygen in the
atmosphere. There are two conditions which trigger the alarm:
• Too little oxygen (deficient)
• Too much oxygen (enriched)
At the Alarm Setpoint for either:
• Alarm sounds
• Alarm light flashes
• Concentration of gas flashes in the
display (FIGURE 2-27).

WARNING
If the OXYGEN alarm condition is reached while using the
instrument as a personal or area monitor, leave the area
immediately; the ambient condition has reached a preset alarm
level. If using the instrument as an inspection device, do not
enter the area without proper protection. Failure to follow this
warning will cause exposure to a hazardous environment which
can result in serious personal injury or death.
Toxic Gas Measurement
The FiveStar Alarm detects certain toxic gases in the
atmosphere. Your instrument may have up to three toxic sensors.
Each of these sensors has a setpoint which causes an alarm if
the gas level goes above that setpoint. When this happens:
• Alarm sounds
• Alarm lights flash
• Concentration of gas flashes in the display.
