EMER STPT 15 2940, 2941, 2942 A value of the preset FVEL STPT, in percent, that the
controller uses as the setpoint when EMER ALM is ON.
(Application 2940 uses EXH STPT.)
LOW WARN 16 2940, 2941, 2942 Displays an ON or OFF status. When the face velocity goes
below the value specified at LOW WARN LMT for the time
specified in ALARM TIME, the point goes into a warning
state (ON); the yellow LED is illuminated at the ODP.
HIGH WARN 17 2940, 2941, 2942 Displays an ON or OFF status. When the face velocity goes
above the value specified at HI WARN LMT for the time
specified in ALARM TIME, the point goes into a warning
state (ON), the yellow LED is illuminated at the ODP.
ALARM TIME 18 2940, 2941, 2942 Time delay for the red and yellow alarm LEDs used to
eliminate sudden changes and false alarms. The average
face velocity must rise above any of the set limits (for
example, HI ALM LMT) for the amount of time specified at
this point before the ODP indicates an alarm condition.
FLOW MAX 18 2941, 2942 Maximum flow setpoint allowed. FLOW MAX will override the
FVEL STPT if the calculated FLOW STPT is greater than
FLOW MAX.
ALM AKNLG 19 2940, 2941, 2942 Displays an ON or OFF status that indicates the Horn
Silence button has been pressed at the ODP to acknowledge
an alarm condition. The point will reset when the alarm
condition clears or another alarm is initiated.
OCC.UNOCC 20 2941, 2942
OCC or UNOCC point controls which face velocity setpoint to
use; OCC FV SET or UNOCC FV SET.
STARTUP MODE 21 2940, 2941, 2942 Toggles the ODP from normal operation to OFF mode. In
OFF mode, the alarms do not sound, the ODP displays OFF
and the RED LED is on.
LEFT SWITCH 22 2941, 2942, 2900 Indicates if the left auxiliary button on the ODP has been
pressed. This is a toggle action digital input; when pressed,
the point is ON. If pressed again, the point is OFF.
ODP STPT SW 22 2940 Indicates if the left button on the ODP has been pressed.
This is a toggle action digital input; when pressed, the
controller changes between HI and LOW flow setpoints.
RIGHT SWITCH 23 All Indicates if the right auxiliary button on the ODP has been
pressed. This is a toggle action digital input; when pressed,
the point is ON. If pressed again, the point is OFF.
ATN.UNATTN 24 2941, 2942 ATTN or UNATTN point controls the mode of operation for
the sash alert function.
AT ALRT AREA 25 2941, 2942 The open area in square feet (SQM) at which the Sash Alert
feature will start beeping the horn during attended operation.
UN ALRT AREA 26 2941, 2942 The open area in square feet (SQM) at which the Sash Alert
feature will start beeping the horn during unattended
operation.
OPEN TIME 27 2941, 2942
When SASH OP ALRT is on, you can silence the alert for the
time entered in OPEN TIME.
SASH TONE 28 2941, 2942 ON or OFF point controls if the ODP will beep for the SASH
ALRT function or if the alarm will just be passed to the
network.
SASH OP ALRT 30 2941, 2942 This point turns ON when the face area is larger than UN
