Selection 6c : Unoccupied Low Alarm Caution Band [SCREEN 11C]
If desired, a caution band can be utilized to warn the operator of an impending alarm condition. The
caution band is a value in FPM or MPS that is added to the unoccupied low alarm set point and will
display a warning message and flash the normal green LED until the unoccupied low alarm set point is
reached, then the unit goes into full alarm. For example if the unoccupied low alarm set point is set to
50FPM and the unoccupied low caution band is set to 10FPM; the APM will display a warning message
for all readings between 51 and 60FPM. Once the airflow velocity drops to 50 or below, the APM will go
into alarm mode. Readings above 60FPM are displayed in the normal fashion. By using the plus and
minus buttons [

Selection 7c : Unoccupied High Alarm Caution Band
[SCREEN 14C]

caution band is a value in FPM or MPS that is subtracted from the unoccupied high alarm set point and
will display a warning message and flash the normal green LED until the unoccupied high alarm set point
is reached, then the unit goes into full alarm. For example if the unoccupied high alarm set point is set to
130FPM and the unoccupied high caution band is set to 25FPM; the APM will display a warning message
for all readings between 105 and 129FPM. Once the airflow velocity increases above 130FPM or higher,
the APM will go into alarm mode. Reading below 105FPM are displayed in the normal fashion. By using
