The G1 control module is the user's interface with the SCBA and ADSU device.
The control module is assembled to the high pressure air source and to the power module by a
pneumatics and electronic hose assembly. The unit combines an analog gauge and graphical
display to provide current status information of the SCBA:
• numeric cylinder pressure
• battery status
• alarms
• power module status
• remaining service time
• Telemetry radio link and evacuation status
The control module automatically lights up the analog gauge and turns the display on when the
user lifts the unit up from the chest.
Furthermore the control module serves the user with a manual alarm button that activates the full
acoustic and visual alarms of the device.
