Control Module (ADSU) (Version with Integrated Electronics only)

WARNING!
The control module has the ability to display calculated remaining service time counting down

to 0 bar (default) or 35% of the rated service pressure or to medium pressure alarm. The user
must determine which option has been selected for the control module in service.
Actual time remaining may be less than the calculated time displayed. Increases in breathing

rate may reduce remaining time more than expected. Use time indicator as general guide only.
The time displayed is based on the continuation of the average breathing rate over the last
three minutes. Increases in the breathing rate after checking the displayed time may result in
less remaining time than anticipated.
Failure to follow this warning can result in serious personal injury or death.

Alarms

The G1 Control Module contains a motion sensor that detects motions of the user automatically.
The related motion alarm is reached within 30 seconds, those 30 seconds are split into 3 levels:
No motion detected:
1. Level for approx. 17.5 seconds, deactivated by moving
2. Level for approx. 20 seconds, deactivated by moving
3. Level for approx. 25 seconds, deactivated by reset button press
4. Level for 30 seconds, full motion alarm, deactivated by reset button press
With optional telemetry module only the full motion alarm is transmitted to the G1 base station and
displayed within the accountability software.
When the SCBA is not in use, it is in sleep mode. During sleep mode, the SCBA periodically
checks for system changes and wakes as needed. The conditions that wake the system from
sleep mode include battery installation, system pressurization, or activation of the ALARM button
on the control module.
The control module also wakes from sleep mode when the user pushes and holds the RESET
button to check the battery status without pressurizing the system. If the user holds the RESET
button after the battery symbol appears, the control module goes into service mode, which
provides additional details about product usage. Only trained personnel are authorized to use
service mode.
Start-up Sequence
WARNING!
If the control module displays a "Do Not Use" icon during start-up, the SCBA must be removed
from service and must be checked and corrected for proper operation by an MSA trained or certi-
fied repair technician.
Failure to follow this warning can result in serious personal injury or death.
Once the device leave sleep mode, it will enter a start-up sequence that will provide the user infor-
mation on the state of the unit for operation.
