G1 Demand Valve (LGDV)
The mask mounted G1 Demand Valve is a pressure-demand LGDV, which maintains a positive
pressure in the full face mask while the SCBA is in use. The positive pressure LGDV reduces the
pressure coming from the pressure reducer further to provide breathable air to the user.
The LGDV is connected to the full face mask with a fixed position Push-To-Connect (PTC)
connection.
The purge cover allows users to activate the LGDV manually or provide a quick burst of air during
use.
In the version with integrated electronics, the LGDV houses an optional electronic module which
provides HUD functionality and microphone placement. The microphones are activated when the
LGDV is connected to the full face mask and the user begins breathing. Inhalation noise is not
amplified by the system. The top button of the LGDV also serves as a buddy light, it lights up
yellow or red if the cylinder pressure falls below a certain threshold.
For the version with integrated electronics, the hose for the LGDV is available in two options,
continuous or quick connect. The continuous hose provides an uninterrupted connection from the
pressure reducer to the LGDV. A quick connect coupling is positioned on the chest between the
pressure reducer and LGDV to enable LGDV removal from the SCBA for testing or repair. Both
types of hoses for electronic versions have integrated wiring and hoses.
In the pneumatics only version, the LGDV is connected to the SL manifold via a quick connect
coupling.
