Chapter 2

Using the FiveStar Alarm

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.

Alarm levels are set at the factory and meet the most commonly

accepted standards; see Chapter 2 of the FiveStar Alarm

Technical Manual for details. Setpoints can be changed to meet

specific conditions.
