A portion of the air coming into the enclosure
passes through the air inlet and across the flow
sensors.
This red light is activated approximately 10-30
seconds after the low flow set point is reached.
Low flow set points are 10-20 fpm below normal
flow.
If no alarm is present, this button will cause the
red lamp to light and the audible alarm to sound.
If an alarm is present, the button will silence the
audible alarm.
This potentiometer is used to set the low flow
indicators for the alarm. It is adjusted with a small
screwdriver.
