How is the pressure indicated on the HUD for the unit?

The pressure indicated on the Heads-Up Display (HUD) for the unit is represented with four lights on the left side of the display. This system utilizes a color-coded format where different lights signal various pressure levels, allowing firefighters to quickly assess their air supply while they are engaged in operations. The use of multiple lights provides a clear and immediate visual representation, enabling the wearer to make informed decisions regarding their air supply status without having to look down at an analog gauge or numeric display. Being able to interpret the air pressure quickly is essential in emergency situations where every second counts.
