Description

The G1 SCBA is a pressure-demand self-contained open circuit breathing apparatus (SCBA)
operating independent of the ambient air for use in atmospheres immediately dangerous to life or
health.
Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a
lung governed demand valve (LGDV) according to EN 137:2006 and a full face mask according
to EN 136:1998 (see Operating Manual of full face mask). The exhalation air is released directly
into the ambient atmosphere.
The integrated alarm and control unit (ADSU) provides the user with the ability to monitor move-
ment through a motion sensor. When a user remains motionless for 30 seconds, the ADSU device
goes into full alarm to alert those around the user. The control module monitors cylinder pressure,
battery status and visually indicates different alarm status of the G1 SCBA.
