Using The Scba With Telemetry Module - MSA G1 SCBA Operating Manual

18.1 Using the SCBA with Telemetry Module

Logging the SCBA on to the Base Station
(1) Turn on the control module on by opening the cylinder valve or by pressing and holding the alarm
button.
(2) An icon representing the user of the SCBA will appear on the base station PC screen.
(3) When the base station has established contact with the SCBA and all initial information has been
obtained, the radio link indicator will appear in the upper left corner of the control module display.
(4) Periodically check the status of the radio link indicator on the display of the control module. If the
signal indicator turns yellow, this means that the SCBA is out of range from the base station. The
signal strength indicator will stop flashing when the SCBA returns within range of the base
station.
CAUTION!
If the signal strength indicator does not appear on the control module display or the base station has
not logged the unit on, the base station cannot monitor the status of that user.
Logging the SCBA off of the Base Station
(1) Once the user has returned to fresh air the control module may be turned off.
(2) Close the cylinder valve and purge the remaining air from the system using the regulator bypass.
When the pressure falls below 200 psi, turn the control module off (sleep mode) by pressing the
reset button twice in approximately one second. (When the SCBA is logged on to a base station,
there may be a delay between the two rapid presses of the reset button and the actual shutdown
of the control module. Before the control module completely turns off, the base station must log
off the SCBA and send out a final confirmation signal.
Evacuation Signal
If the SCBA is logged on to the base station, the incident command will have the ability to send an
evacuation signal to the SCBA. When an evacuation signal is sent to the SCBA, the power module
will begin to beep repeatedly and a flashing evacuation icon will appear on the control module display.
The evacuation alarm will continue to sound until the reset button on the control module has been
pressed twice within approximately one second. This confirms the evacuation by sending a confirma-
tion signal back to the base station. The evacuation alarm can only be reset on the SCBA after the
unit has been turned off and restarted.
