G1 Integrated SCBA System
Primary Low Pressure Warning Device
The primary low pressure warning device is an acoustic warning device (signal whistle). It triggers
a continuous warning signal when the cylinder pressure drops below 55 5 bar.
Depending on pneumatics the low pressure warning device is located at the G1 Pressure Reducer
next to the Cylinder and Valve Assembly (Fig. 5) or within the Single Line (SL) Manifold (Fig. 6
"SL manifold").

Quick-Fill Coupling (optional)
The Quick-Fill coupling (see also chapter 12) can be used to recharge the cylinder in extraordinary
situations while it is attached to the SCBA.
