Operating
Condition Screen The Operating Condition screen shows the user the active operating conditions of the
pressurized space.
The Room Label at the top of the screen can be defined by the user to ensure the
viewer understands which room is actively being monitored by the SRCM. See
Changing Room Name page 10, to enter text for your specific room.
The PRESSURE indication shows the intended direction of airflow for the space.
POSITIVE for airflow out of the space, NEGATIVE for airflow into the space, NEU-
TRAL for airflow conditions that may vary, and STANDBY for use when there is no
need to verify the direction of airflow (alarms are disabled).
The OPERATION indication shows whether the pressurized space is within normal
operating parameters (within alarm thresholds), or whether there is an alarm or warn-
ing condition. If operation is within alarm thresholds, a green NORMAL indica-
tion is shown. If operation is near either high or low alarm threshold limits, a yellow
WARNING indication is shown.
If operation is at or beyond high or low threshold limits, a red ALARM indication is
shown. If Audible Alarming is Enabled, a piezo buzzer will sound and a SILENCE
menu button will appear. Pressing the SILENCE button will shut off the alarm for
the period of time defined in the alarm configuration. Alarm operation can be config-
ured to blink or sound an audible signal. See Section, Alarm Setup, page 15, for more
about setting up ALARM and WARNING conditions.
In addition to pressure indication, OPERATION also displays whether a door is open.
If a door switch is configured, an open door contact will display a yellow DOOR
indication.
