HUD Visual Pressure Gauge and Visual Warning, BAC and DDU Visual Warning

A wireless Heads-Up Display (HUD) inside the face mask acts as a secondary visual

pressure gauge and also provides visual low air warnings at both 1/2 and 1/3

cylinder pressure. Flashing yellow and red LED’s will activate when the primary air

supply pressure has dropped to approximately 50% and the ashing red LED only at

approximately 33%. The visual ashing red LED will continue to ash until the cylinder

content is depleted and the unit is switched off.

Flashing red LEDs are also activated on the BAC and the Digital Display unit at 1/3

cylinder pressure for other reghters to see.
