EMER STPT
15
6740, 6741, 6742
A value of the preset FVEL STPT, in percent, that the
controller uses as the setpoint when EMER ALM is ON.
(Application 6740 uses EXH STPT.)
LOW WARN
16
6740, 6741, 6742
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
6740, 6741, 6742
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
6740, 6741, 6742
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
6741, 6742
Maximum flow setpoint allowed. FLOW MAX will override the
FVEL STPT if the calculated FLOW STPT is greater than
FLOW MAX.
ALM AKNLG
19
6740, 6741, 6742
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
6741, 6742
OCC or UNOCC point controls which face velocity setpoint to
use; OCC FV SET or UNOCC FV SET.
STARTUP MODE
21
6740, 6741, 6742
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
6741, 6742, 6700
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
6740
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
6741, 6742
ATTN or UNATTN point controls the mode of operation for
the sash alert function.
AT ALRT AREA
25
6741, 6742
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
6741, 6742
The open area in square feet (SQM) at which the Sash Alert
feature will start beeping the horn during unattended
operation.
OPEN TIME
27
6741, 6742
When SASH OP ALRT is on, you can silence the alert for the
time entered in OPEN TIME.
SASH TONE
28
6741, 6742
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
6741, 6742
This point turns ON when the face area is larger than UN
