Operation
The following pages describe how to operate the SRCM using the touch-screen interface.
The screen has two basic functions. The primary mode of operation displays the Home
screen, which shows the end-user pressure values, messages, text, and other data intended
for visual pressure verification in the facility. The second mode of operation is the Administrative Menu (Menu) screen, which permits setup, configuration, and changes to
how the SRCM operates. After changes have been performed on the Menu screen, functions are saved and operation returns to the Home screen.

Home Screen
The Home screen is the normal continuous operating mode of the SRCM. The Home
screen shows a Condition Banner on the left one-third of the screen, and Operating Conditions on the right two-thirds of the screen.

The Condition Banner is a screen that can be configured by the end-user or facility
manager to display a message to staff on the floor. The Condition Banner can be Green,
Yellow, or Red, depending on the type of message desired.
The Condition Banner does not affect or respond to pressure in the space. Banner screens
are only messages intended to be communicated to staff, personnel, and other people outside the room. The banner does not change color for any alarms, warnings, or changing
conditions of the space. The banner may be changed manually, as required, by pressing
the touch-screen anywhere within the banner color region.

the YELLOW banner to indicate room
is under transient use and entry is restricted.
Once the messages of each of the three Condition Banners are defined in the
Menu section, the user can cycle through all three conditions by simply touching
the left one-third of the screen in any region. If passwords are enabled, the user
will be prompted to enter their password before proceeding. Each of the three colored screens can have a unique message defined. See Section: Setup Display, page
11, for instructions on how to setup the Condition Banner.
When the Operating mode of the SRCM is set for PRESSURE = STANDBY, the
top part of all three banners will display STANDBY to indicate that active use of
the SRCM has been suspended and no alarms will occur. See Section, Setup Display, page 11, for more information on STANDBY mode.

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 Section, Setup Display, 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, NEUTRAL 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
warning condition. If operation is within alarm thresholds, a green NORMAL indication 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 configured 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.

Pressure Value
Slider Bar and
Setpoint Values
Pressure Value
A black banner displays the actual pressure reading from the space, in either
Water Column inches (“ WC) or Pascals (Pa). The resolution of display can
vary, depending on desired configuration; either 2, 3, or 4 significant digits. The
accuracy of measurement remains the same regardless of the number of digits
displayed.
The blue banner below the pressure value shows where the current pressure
reading is in relation to alarm setpoints. The value at the left of the blue banner
is the low setpoint value, and the value on the right is the high setpoint value.
The middle “Cursor” represents the curremt measured pressure value.

Slide Bar On/Off
If the user does not wish to see the actual pressure value or slider bar, it can be turned
off using the Menu screen. Operation of the pressure sensing and alarming is unaffected. See Section, Menu Screens, page 7 .
Occupied and
Standby Modes
By pressing the touch-screen directly on the word POSITIVE (or NEGATIVE, NEUTRAL, or STANDBY), the user is able to change the condition of the room between
OCCUPIED and STANDBY modes. A pop-up menu appears to enable selection. If
passwords are enabled, the user must first enter a password to proceed with the change.
In OCCUPIED mode, the full function of the SRCM is active. In STANDBY mode, the
SRCM will perform all functions except that alarming will be disabled (both audible
and visual alarms). The STANDBY mode is designed to put the SRCM into a mode
where room pressurization is not critical, such as cleaning, patient transfer, or longerterm unoccupied status.
