PASS Device

The PASS device on the G1 SCBA is made up of three components: control module, power module,
and battery module (alkaline, rechargeable). The PASS device monitors movement through a motion
sensor. When a user is motionless for 20 seconds, the PASS device goes into pre-alarm. After
30 seconds, the PASS device goes into full alarm to alert those around the user. The PASS device
also monitors cylinder pressure and battery status.

2.6.1 Control Module

The G1 control module is the user's interface with the SCBA and PASS device.
A pneumatic and electronic hose assembly connects the control module to the high-pressure air
source and the power module. The control module has an analog gauge and a graphical display to
provide information such as numeric cylinder pressure, battery status, alarms, and service time
remaining (optional).
US
When the control module display is being read by the user, buddy lights do not flash on the control
module, but a white gauge light illuminates the gauge and display when the SCBA is in standard
mode. If the SCBA is equipped with the optional telemetry module, the radio link status and evacuation
alarms also show.
The control module contains the integrated PASS motion sensor. The ALARM button for the control
module activates the full PASS alarm with or without air pressure.
