The
Class1
Oxygen Remaining Display is designed to provide operators with a
visual indication of Oxygen remaining and an audible warning when there is
less than 20% oxygen remaining. The 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 represents oxygen volume information in an easy to interpret LED
bargraph display as a percentage of maximum calibrated pressure. The display includes a visual warning and an auxiliary warning alarm output.
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.
