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.
Slider Bar and Setpoint Values
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.

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
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.

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.

Setup Unit
Upon initial installation, the Setup Unit screen should be used to define installation
parameters specific to the job site.
The SRCM can take as input, the signal from two separate pressure transducers. These
are configured for either Primary Room or Secondary Room (an anteroom is an example of a secondary room). When two transducers are used, the Home screen display of
the SRCM can toggle between each space to indicate the status of each room momentarily, cycling from one to the other a few seconds apart.

Change, if necessary, to match sensor being used. OnBoard is the default, which uses
the sensor manufactured on-board the unit. Alternatively, an external sensor (also
known as “external transducer” such as a Setra 264 or Setra 267) may be used. If an
external sensor is used, change this selection to Analog Ch1. The FS output and range
of the external sensor will need to be entered.
Secondary Room
Sensor
Change, if necessary, to match sensor being used, if there is one present. None is the
default. An external sensor (also known as “external transducer” such as a Setra 264 or
Setra 267) may be used for the secondary room, or anteroom. If an external sensor is
used, change this selection to Analog Ch1. The FS output and range of the external sensor will need to be entered.

Primary Analog
Output
This Analog Output (AO) is used to communicate the value of the differential
pressure to an external source such as a Building Management System (BMS).
The value is scaled as either 4-20 mA, 0-5 Vdc, or 0-10 Vdc, selectable. A normalized pressure value is generated once every 100 milliseconds. The analog
output is only available for the Primary room.

Units of measurement to show on the Home screen, selectable as either inches
of Water Column (“WC) or Pascals (Pa).
The SRCM is manufactured with an on-board differential pressure transducer.
This transducer is manufactured to specifications for fixed minimum and
maximum pressure measurement, known as the full-scale range of the transducer. When the on-board transducer is used exclusively, these values cannot
change. Alarm setpoints cannot be set above the positive value or below the
negative value. If a wider or narrower sensor range is required for the project,
an external pressure transducer such as a Setra 264 or Setra 267 may be chosen
to match the requirements. See more above under Primary Room or Secondary
Room.
If an external transducer is used, the full-scale values and other parameters need
to be configured into the SRCM so the unit understands the scale of measure-

Display Averaging (tenths of seconds)
This function is used to improve the stability of the pressure value displayed on the Home screen, so significant digits do not change rapidly.
It is used more often in environments where the user requires higher
display resolution (4 digits) but the ambient pressure is unstable. By increasing the number, the effective number of measured data points is increased and a weighted average is developed. Input the number in tenths
of a second for the response time of the display to a pressure change.
There is no ratcheting of the display or a deadband. The pressure change
is very smooth. For example, entering 10 equates to the display reaching
final value in 1 second. Entering 2 equates to final value in 200 ms.
Display Averaging does not affect the Analog Output response time, only
the apparent stability of the pressure display. Display Averaging also
does not affect Alarm Thresholds or Alarm Delay.
What Pressure To Display
This function defines what pressure value is shown on the Home screen
under normal operating conditions. This can be Primary Only, Secondary
Only, or Toggle, depending on what room is most important for visual
pressure verification.
If this is set to Primary Only, then the Home screen will show the pressure value read by the primary pressure transducer (either on-board, or
the alternate primary transducer configured from a separate transducer, if
one is used).
-12-
If a secondary transducer is in use, and an alarm condition occurs in the secondary room, the display will toggle and remain on the secondary room and pressure value as long as the alarm condition is present in that space.
If this is set to Secondary Only, then the Home screen will show the pressure
value read by the secondary pressure transducer (anteroom for example). In this
case, if an alarm condition occurs in the primary room, the display will toggle
and remain on the primary room and pressure value as long as the alarm condition is present in that space. If no Secondary Room is configured on the Setup
Unit screen, attempts to choose Secondary Only will result in the error “Secondary room source is NONE.”
If this is set to Toggle, then the Home screen will show the pressure value read
by both transducers, alternating back and forth momentarily. If an alarm condition occurs in either room, the display will toggle to the appropriate room and
pressure value and remain on that room as long as the alarm condition is present. If both rooms are in alarm, then the alarm condition and pressure values
will toggle
Supervisor and Operator Passwords
The password function provides security against changed configurations by unauthorized users. This is accomplished by using two levels of password protection. These can be enabled or disabled.
The Operator level allows access to change between Occupied and Standby
room modes, but no other changes.
The Operator is the person that has day-to-day interaction with the monitor to
change operating modes from Occupied mode to Standby (where no alarms are
active), the operator can also respond to local audible and visual alarms. This
can be a Nurse or a Lab Technician. The SRCM was designed to make interaction with the unit as easy as possible for the Operator. Changes to messages and
to the room mode requires simply touching active areas of the display. If Operator Password is enabled then a password will be needed before the change can
be made.
The Supervisor Level allows full access to all menus. The Supervisor has access
to all levels of the menu structure. This mode is used during initial configuration
and follow-on reconfiguration.
NOTE: The master Supervisor password is 351, and will work for any
condition where a user may need to reset passwords.
-13-
Condition Banner TabCustomizing Blinking
Screens
The Condition Banner tab allows the user to choose whether certain parts of the
screen blink or not. Blinking components on the Home screen are intended to
draw more attention to the Condition Banner or the OPERATION indicators, for
the purpose of making exception conditions more noticeable to staff concerned
with room pressurization status.
Alarm Blink Defines the behavior of the red
ALARM indicator on the Home
screen. Normal Blink is used for
the green NORMAL indicator.
Warning Blink Applies to the yellow WARNING,
DOOR indicator.
Blink in Red/Green/Yellow Applies to the Condition Banner
messages and icon on the left onethird of the Home screen.
Save & Exit Saves the selections made on this
screen.
-14-
Setup Alarm
The Setup Alarm screen permits authorized users (based on password level) to
configure alarm behavior, such as the duration of alarms, methods of clearing
alarm condition, and how alarms are acknowledged.
Define which room the
Setup Alarm conditions will
apply to
For each room (Primary or
Secondary), define whether
the room pressure will be
Positive, Neutral, or Negative
Latch Alarm If enabled, causes the display of red ALARM on the
Home screen to remain, even if room pressurization
returns to NORMAL. Latch Alarm enabled requires that
an alarm event be acknowledged and that the pressure
returns to within the normal range. This is useful because it forces recognition that an alarm event occurred.
The alarm will still be on even if the pressure returns to
normal range. Only when the alarm is acknowledged will
alarming cease. When disabled, the alarm will be silenced
when the pressure returns to normal range without requiring acknowledgement.
When a Latch Alarm occurs, the Home screen displays a
RESET button to the right of the Menu button. Press the
RESET button to acknowledge and reset the Latch Alarm
condition.
Alarm Delay Time between when the pressure went outside alarm
setpoints and when the unit goes into alarm mode. This is
useful in preventing false alarms. For example, if Alarm
Delay is set to 20 seconds, the staff has 20 seconds to
open a door, enter the room and close the door before
the alarm sounds (if audible alarms are enabled). Alarm
Delay also applies to alarms annunciated to a remote annunciator via the SRCM Digital Output (hardware configuration).
-15-
Audible Alarm Enables or disables the audible buzzer. Regardless of
whether audible alarming is enabled or disabled, the red
ALARM condition will show on the Home screen, annunciate to an SRAN, and propagate to a configured Digital
Output. If an alarm occurs and the audible alarm is enabled, a new SILENCE button will appear on the Home
screen so that the operator can silence the audible alarm.
The audible alarm is silenced only for the period of time
defined by Mute Time Out.
Mute Time Out Sets the time (in seconds) that the alarm will remain silent
after pressing the SILENCE button before the audible
alarm resumes again. This assumes that the room pressure
condition is still outside the normal setpoint operating
limits. Mute Time Out can be set from 0 to 9998 seconds.
Entering a value of 9999 will silence the audible alarm
“forever,” as long as a new alarm condition does not occur.
Digital Input (DI) Used for monitoring the door status, open or closed. The
DI is a Normally-Closed dry contact. A door jamb or
valve pressure switch must be wired to the terminals labeled DOOR in the rear of the unit. When the door opens
the contact will open, and this will show a yellow DOOR
Warning on the Home screen.
Deadband is adjustable from 0 to 10% and represents the region
within the setpoint range where yellow WARNING is displayed on the Home screen to indicate that the pressure is
near ALARM limits. If set to 0, no WARNING will occur,
only ALARM when the pressure value reaches setpoints.
If set to any other value, WARNING will be displayed if
the pressure value reaches that percentage of total pressure setpoint range.
When the unit goes outside of the deadband range the
alarm will occur. The alarm will remain until the pressure
returns within the alarm limit range (or acknowledged
Latch alarm) minus the setpoint.
Buzzer Volume The buzzer volume can be adjusted from one—four, with
four being the highest sound level. The alarm buzzer is
disabled using audible Audible Alarm disable function.
-16-
Alarm Set Point
For each space, Primary Room or Secondary Room, this screen is used to define
the alarm setpoints. When the room is then set to Positive, Neutral, or Negative,
the setpoints and conditions configured here are in effect for alarm and warning
conditions.
-17-
Alarm Matrix
The SRCM has a great deal of flexibility to define alarm conditions. Alarms and
warnings can be configured for primary and secondary rooms, and for the door.
Room display can toggle between Primary and Secondary. The following table

USB Configuration Cloning
The SRCM has USB port built in for the purpose of duplicating configurations
when multiple units are being setup with similar configurations. To use this
function, a USB 2.0 thumb drive of capacity 256 megabytes or larger must be
used. The thumb drive must have at least 100K or free memory available. The
USB port should only be accessed by qualified personnel.
Setra recommends the Kingston DataTraveler 112, 4GB (minimum) flash drive
along with the aid of a short mini-USB adapter cable from Tensility International Corporation, P/N 10-00003. No PC is required.

To access the USB port, first remove the faceplate cover and set it aside. The
USB port is located on the right side of the touch-screen display driver board,
and is accessed by removing the security screw and flipping up the display
housing. A mini-USB 5-pin Male to USB A Female cable (from Tensility International Corporation, P/N 10-00003) is required to connect a standard USB 2.0
compliant thumb-drive to the SRCM USB port.
To make use of the cloning feature, first setup one SRCM with a configuration that represents most other SRCM units that will be used during installation. Configure the “master” unit with all parameters needed, including alarm
thresholds, condition banners, blinking operations, I/O configuration and so on.
Make sure the Save & Exit function is used to properly save your configuration.
This “master” setup will then be downloaded to the thumb drive and for use
uploading to other units.

As soon as the thumb drive is connected the SRCM it will be recognized and
bring up a Drive Connected menu.
• Select Read to transfer the master SRCM configuration from the unit to the
thumb drive.
• Select START to initiate the copy operation.
Remove the thumb drive and cable and move to the first “slave” unit to be
configured. With power applied to that unit, connect the thumb drive and cable.
Select Write and START to write the master configuration to the new slave unit.
A Write Process Successful message will appear if the configuration has been
written to memory. Review the various Menu screens of the slave unit and
subsequent units to confirm the proper configuration is stored. In most cases the
only change that will be required to clone SRCM units is Primary and Secondary Room labels that match the location of installation.
