Overview of Alarm Functions

Define whether Alarm 3 activates based on oxygen levels, the start of a calibration, or
the start of a verification (Select Function). All other alarms are set to activate based on
only a single condition ; for Alarm 4 this condition is levels of oxygen, for Alarms 5 and
6 this condition is high combustible levels (% or PPM scale), for Alarms 7 and 8 this
condition is high methane.
