APPLICATIONS
The Pressure Alarm System is designed to be used with Thermco gas mixers to indicate low inlet gas pressure. The Pressure Alarm System may also be used for other pressure monitoring applications.
When applied to smaller gas mixers, the Pressure Alarm System is normally mounted on the wall next to the gas mixer. For larger floor mounted gas mixing systems, the Pressure Alarm System may be mounted on the gas mixer.
HOW ALARMS OPERATE
If the inlet pressure drops below the alarm value, the pressure switch in the Pressure Alarm System will trip, lighting the specific indicator light and sounding the horn. The horn silence button may be pushed to silence the horn. When the inlet pressure returns to normal, the alarm lights and horn will automatically reset.
OXYGEN SERVICE
Parts wetted by oxygen are compatible with oxygen and cleaned for oxygen service.
