How do you adjust the alarm set point?

• A. Adjust the airflow indicator minimum level CCW or CW
• B. Press the test push button
• C. Change the battery
• D. Notify Cognizant Officer

Answer: (A)

The alarm set point is defined by the minimum airflow level on the airflow indicator. To adjust it, turn the airflow indicator control in either direction (CCW or CW) to change the minimum level that must be present before the alarm sounds. This directly sets the threshold at which the alarm will trigger. The test push button is only for verifying the alarm works, not for changing its setting. Replacing the battery won’t change the alarm threshold, and notifying the Cognizant Officer is a procedural step, not a way to adjust the alarm.
