Application
701, 702, Indicates that a high pressure alarm is active.
703, 704
701, 702, Indicates the Remote Pressure Transmitter for the occupied
703, 704 room has failed.
702, 704 Indicates the Remote Pressure Transmitter for the anteroom has
failed.
701, 702, Indicates if the door alarm is active.
703, 704
701, 702, A time delay before alarming to prevent nuisance alarms.
703, 704 Valid entry: 0-600 seconds.
701, 702, A time delay that the door is allowed to be open before an alarm
703, 704 is triggered. Valid entry: 0-600 seconds.
701, 702, A time delay for changing from one mode of pressurization to
703, 704 another. Valid entry: 0-600 seconds.
701, 702, Determines the operating mode for pressurization. If the value of
703, 704 ACTIVE.NTRAL (Point 10) is ACTIVE, the operating mode is
either positive or negative.
701, 702, State is determined by the differential pressure, the high and low
703, 704 pressure limits, and the time delays.
701, 702, Indicates the state of the relay coil during normal operation. If set
703, 704 to NCLOSE, the relay coil will be energized during normal
conditions, and de-energized during alarm conditions.
701, 702, An operator-defined point. If a door switch is present, the point
703, 704 should be set to YES. If a door switch is not present, the point
should be set to NO. Valid entry: YES or NO.
701, 702, Indicates the differential pressure of the occupied room.
703, 704
702, 704 Indicates the differential pressure of the anteroom.
701, 702, Digital input point used to determine the door position.
703, 704, 790
702, 704 A digital point that reverses the signal being sent to the Constant
Volume Controller when the anteroom is not pressurized the
same as the occupied room. Valid entry: NOPEN or NCLOSE.
701, 702, Expected state of the door input during normal operation. If set
703, 704 for NCLOSE, the door input will expect a signal that is a closed
circuit (a short) during normal conditions and an open circuit
during alarm conditions. Valid entry: NOPEN or NCLOSE.
701, 702, Digital input point used to determine the state of HORN SILENCE
703, 704, 790 (Point 48).
701, 702, Represents the average value of DP1 RAW (Point 68) for the
703, 704 period of time set in CAL TIME (Point 44). DP1 RAW is sampled
for averaging when CAL DP1 (Point 42) is set to DONE. When
CAL TIME has elapsed, the average value of DP1 RAW for this
time period will be displayed in this field.
