This function is for display purposes only, and shows a value corresponding to the cur-rent airflow through the
detector.
4.29
Flow high limit
Flow monitoring tab
This value is the level above which airflow needs to increase to trigger a fault indication (which may indicate a
loose or damaged inlet pipe).
Flow low limit and Flow high limit are automatically set up on initial power-up.
4.30
Flow low limit
Flow monitoring tab
This value is the level below which airflow needs to be reduced to trigger a fault reading (which may indicate a
blocked pipe).
Flow low limit and Flow high limit are automatically set up on initial power-up.
4.31
Aspirator speed
Flow monitoring tab
This function has no current use on the FastSense 25 (reserved for future expansion).
