What happens if the alarm button is pressed on the control module?

When the alarm button is pressed on the control module of the MSA G1 SCBA, it activates the Personal Alert Safety System (PASS) alarm. The PASS alarm is a critical safety feature designed to alert others when a firefighter is in distress or has not moved for a specific period. By activating this alarm, it signals nearby personnel that assistance is needed, enhancing safety in hazardous environments.

The other options do not accurately describe the function of the alarm button. For instance, turning off all alarms or resetting the battery warning does not align with the alerting purpose of the alarm button. Similarly, while sending a distress signal to command is important, the PRESS alarm's primary role is to indicate a personal emergency situation rather than to relay signals directly to command.
