How long should the control module remain motionless until the full alarm sounds?

The correct answer is 30 seconds because the MSA G1 SCBA control module is designed to enhance user safety by ensuring that the user is fully aware of their surroundings and is not in a state of inactivity for an extended period. The 30-second motionless delay allows the system to assess whether the user is conscious and moving in the environment. If the user remains stationary for this duration, it triggers a full alarm to alert nearby personnel to the potential issue.

This safety feature is critical, especially in hazardous environments where a lack of movement may indicate distress. Setting the motionless timer to 30 seconds strikes a balance between giving the user enough time to regain movement and ensuring rapid response if they are incapacitated. The other durations may not provide the optimal timeframe for assessing the user's condition effectively.
