General Description
It is your responsibility to know how to use the
FiveStar Alarm. When used properly, the FiveStar Alarm will
alert you to the presence of combustible gases and vapors and
to atmospheres that are rich or deficient in oxygen. It will also
alert you to the presence of specific toxic gases if it is equipped
with sensors for those gases. These conditions are displayed
clearly and simultaneously on the face of the instrument.
