Features
The Class1 Oxygen Remaining Display is designed to provide operators with a visual indication of Oxygen remaining and an audible warning is inactive whenever the pressure is below 50 PSI so that it will not sound when the supply is turned off. The display offers an easy to interpret LED bar graph display as a percentage of maximum calibrated pressure. The display includes an auxiliary alarm warning on top of visual warnings.
When the relative volume of oxygen remaining reaches 25%, the bars will begin to flash, and when the system pressure drops to 20%, the auxiliary output will turn on. The alarm can be silenced with an alarm silence switch. Once the alarm is silenced, it will remain silent until the unit is turned off and then back on, and will reset whenever the volume of air exceeds 20%. When the alarm is silenced, there will be an alert chirp every fifteen (15) minutes to remind the operator that the oxygen supply is low.
