Home Screen
Overview
The following pages describe how to use the BACnet SRCM. 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 secondary mode of operation is the
Administrative Menu screen, which permits set-up and configuration, and changes how
the SRCM operates. After changes have been performed on the Menu screen,
functions are saved and operation returns to the Home screen.
If you do not interact with the touch screen for more than one minute, the screen will
automatically return to the Home screen.
Many administrative settings can be written over the network.
Home Screen
The default screen has two modes. You can switch modes by selecting the SLIDER
ON or SLIDER OFF button on the bottom of the Administrative Menu. The Home
screen is the normal, continuous operating mode of the SRCM.
The Home screen shows a Condition Banner on the left of the screen, and Operating
Conditions on the right of the screen.

Condition Banner
The Condition Banner, on the left of the screen can be configured by the user or
Facility Manager to display a message to staff on the floor. The Condition Banner can
be Green, Yellow, Red or Blue, depending on the type of message desired outside the
pressurized space. The Condition Banner is set up in the Setup Display-Condition
Banner tab of the Administrative Menu. The Condition Banner also has an option to
display in full screen mode. The Condition Banner will change to Red in alarm state
regardless of the current configuration. You can manually change the banner by
pressing the touch screen anywhere within the banner color region.

Condition Banner - Touch Screen Operation
Condition Banner - Touch Screen Operation
You can cycle through all four conditions by simply touching the left third of the screen
in any region. If passwords are enabled, you will be prompted to enter their password
before proceeding. Each of the four colored screens can have a unique message
defined.
Alarms Cause Condition Banner to Turn Red
When alarm occurs, the Condition Banner changes as follows:
1. The Condition Banner will turn to Red and will blink irrespective of the color mode
selected by the user. User-configured color mode: “Alarm Blink” and “Blink in Red”
in the Setup Display screen will remain same. The operation field which displays
the alarm state of the system will also blink. When the system returns to normal,
user-configured settings will be retained.
2. The Message text on the bottom of Condition Banner symbol and user-defined text
on top of the Condition Banner symbol will be temporarily displayed as ALARM as
shown.
3. The Condition Banner can now be configured so that any of the Condition Banner
colors can be programmed to blink when that condition occurs. For example, if an
alarm occurs, the Red color can be programmed to blink; similarly, the Yellow
warning, Green, and Blue can be programmed to blink.
Condition Banner Functions
The Condition Banner configuration on the Display screen will have three options:
Active, Standby, and No Action for all four colors (Red, Yellow, Green, and Blue).
When Active is selected, the Occupancy Status object of the SRCM will be active.
When Standby is selected, the unit will go into Standby mode (No alarms will be
generated) when the corresponding color condition is selected.
When No Action mode is selected, no action will be taken other than to display the
Condition Banner screen that has been associated with the No Action mode.

Operating Condition Screen
Operating Condition Screen
The Operating Condition screen shows the active operating conditions of the
pressurized space.
The Room Label at the top of the screen can be defined to ensure the viewer
understands which room is actively being monitored by the SRCM.
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 is displayed. 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
In addition to pressure indication, OPERATION also displays. 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).
Slider Bar and Setpoint Values
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 current measured pressure value on the setpoint scale.
Slider Bar On/Off
If the you do not wish to see the actual slider bar, it can be turned off using the Menu
screen. Operation of the pressure sensing and alarming is unaffected. See Section,
Menu Screens.

Active and Standby Modes
Slider bar is turn on. This displays when no parameters are configured. Pressure
still displays.
Active and Standby Modes
By pressing the touch-screen directly on the word POSITIVE (NEGATIVE, NEUTRAL,
or STANDBY), you can change the condition of the room between ACTIVE and
STANDBY modes. A pop-up menu appears to enable selection. If passwords are
enabled, you must first enter a password to proceed with the change.
In ACTIVE 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 longer-term
unoccupied status.
This operation can be password protected so that only an Operator or a Supervisor
can make this change. Passwords are set up in the Setup Display Advanced tab.
Menu Screens
Pressing the MENU button on the Home Screen brings up the Administrative Menu. If
passwords are enabled, you must enter the correct password before being authorized
to make changes.

Setting the Application
The SRCM Room Pressure Monitor is a standard BACnet device; therefore, it does not
contain an application point. The SRCM must be set up at the field panel using
application numbers that are specific for each project, in the range of 10,000 through
11,999. Nothing is required to set up the application number in the SRCM device.

Setup Unit
Room - Primary or Secondary
Setup Unit
The SRCM is configured using built-in touchscreen menus.
Select the MENU button on the touchscreen to enter the setup screens.
The SRCM can take as input, the signal from two separate pressure transducers as
well as temperature, humidity, and user-defined (for example CO2) inputs for up to two
rooms. These are configured for either Primary Room or Secondary Room (an
anteroom is an example of a Secondary Room). When two transducers are used, you
can toggle between each room on the Home screen display of the SRCM to view the
status of each room momentarily, cycling from one to the other a few seconds apart, or
the display can be locked on either of the two rooms.
Figure 2: Home Screen Display.
*If CH-1 is selected for the Primary Room, it will not be an available option for the
Secondary Room.
Room - Primary or Secondary
To set up the parameters for a room select either the Primary or Secondary button.
Primary Room Sensor
The Onboard Sensor is the defaultPrimary sensor, which uses the sensor
manufactured on the unit. If the OnBoard Sensor is selected, a box displays showing
the pressure range (SENSOR FS) and engineering unit. Change, if necessary, to
match the sensor being used, if there is one present.
Alternatively, an external sensor (PPRESS.SRC, PTEMP.SRC, PHUM.SRC,
PUD.SRC) (also known as an external transducer) such as Siemens QBM3100 can be
used. If an external sensor is used, change this selection to ADC CH-1 (Analog Input
1) or ADC CH-2 (Analog Input 2). The FS output and range of the external sensor must
be entered.

Room Parameters
Secondary Room Sensor
None is the default for the Secondary Room sensor. Change, if necessary, to match
the sensor being used, if there is one present. An external sensor (SPRESS.SRC,
STEMP.SRC, SHUM.SRC, SUD.SRC) (also known as an external transducer such as
Siemens QBM3100 Series) can be used for the Secondary Room or anteroom. If an
external sensor is used, change this selection to ADC CH-1 or ADC CH-2, which uses
Analog Input 1 or Analog Input 2, respectively. The FS output and range of the external
sensor must be entered.
Room Parameters
The SRCM can display up to four parameters for each of two rooms. The parameters
are Pressure, Temperature, Humidity, and User-Dfined (for example, CO2). Start with
the Primary Room and set up the parameters to be monitored and displayed on the
default or Home screen. As parameters and inputs are selected, further selection of
parameters and inputs become self-limiting. (For example, if Temperature is selected
in Parameter 2, it is not available for selection in Parameter 3 or 4.)
Start with Parameter 1 (PRIM.PARAM1, SEC.PARAM1), this is the Room
Pressure. Select the Input Source as OnBoard, ADC CH-1 or ADC CH-2.
Parameter 2 (PRIMPARAM2, SEC.PARAM2) - Select None, Temperature
(suggested) or Humidity. Select Source as ADC CH-1, ADC CH-2, or BACnet.
Parameter 3 (PRIM.PARAM3, SEC.PARAM3) – Select None, Temperature or
Humidity (suggested). Select Source as ADC CH-1, ADC CH-2, or BACnet.
Parameter 4 (PRIM.PARAM4, SEC.PARAM4) – Select None, User Defined.
Label
Touch the Label check box and use the data entry keypad to enter the Room Label for
the Primary Room (PRIM LABEL, SEC LABEL). The name displays at the top of the
Home screen and identifies the room that the parameters refer to. Press the
Secondary Room button to select the Secondary Room (generally an anteroom) and
label that room if desired.
Primary Analog Output
This Analog Output (ANALOG OUTPUT) is used to communicate the value of the
differential pressure of the Primary Room to an external source such as a Building
Management System (BMS). The value is scaled as either 4 to 20 mA, 0 to 5 Vdc, or 0
to 10 Vdc (ANALOG TYP). A normalized pressure value is generated once every 100
milliseconds. The Analog Output is only available for the Primary Room.
Engineering Unit
Units of measurement display on the Home screen, and can be either Inches of Water
Column (“WC) or Pascals (Pa). The units are factory-calibrated as “WC. If the unit is
changed to Pa, the range will be changed to Pascals (Pa). This is selected from the
Parameter 1 tab as it is associated with the Primary Room pressure (PRIM.P.UNITS).

Analog Inputs
Sensor Range
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 be changed. 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, and external pressure transducer can
be chosen to match the requirements. See Primary Room Sensor or Secondary Room
Sensor for additional information.
If an external transducer is used, the full-scale values and other parameters must be
configured into the SRCM so that the unit understands the scale of measurement
being received on the Analog CH-1 or Analog CH-2 inputs.
Analog Inputs
The SRCM has two Analog Input channels (ADC Ch1 and ADC Ch2).
If a 4 to 20 mA transmitter is used as an analog input, then a 250 ohm resistor must
be installed. This will be translated into a 1 to 5 Vdc input at the input terminals.
The unit takes an Analog Input from any transducer or transmitter: pressure
(PRIM.PRESS, SEC.PRESS), temperature (PRIM.TEMP, SEC.TEMP), or humidity
(PRIM.HUM, SEC.HUM). If an external transducer is used, the full scale values and
parameters need to be configured into the SRCM so that the unit understands the
scale of measurement being received on Inputs ADC CH-1 or ADC CH-2.
The following examples uses a pressure transducer to measure Secondary Room
pressure (SEC.PRESS). The pressure transducer has a range of ±1 “WC and an
output of 4 to 20 mA over that range.
Figure 3: Pressure Transducer Measuring Secondary Room Pressure.
The following example uses a temperature sensor to measure the Primary Room
temperature (PRIM.TEMP). The temperature range is ± 50°C with a 1 to 10 Vdc output
over that range.

The following example uses a humidity sensor to measure the Primary Room relative
humidity (PRIM.HUM). The range is 0 to 98% RH with a 0 to 10 Vdc output.
Figure 5: Humidity Sensor Measuring Primary Room Humidity.
Changing the Room Name
The room name shown on the top part of the Home screen is changed by using the
Label check box (see Figure 6). Depending on whether the Primary (PRIM LABEL) or
Secondary Room (SEC LABEL) button is enabled, the corresponding Label check box
displays. A label can contain a maximum of 18 alphanumeric characters.
Press anywhere in the Label check box to open the on-screen keyboard where you
can enter the name of the room label. It is not necessary to touch the white area next
to the Label, simply start entering data using the keyboard. When you are finished,
press ENTER. Press the Save & Exit button to save the configuration and exit.

Setup Display
The Setup Display screen permits authorized users (based on password level) to
configure Condition Banner messages and other Home screen options. There are four
tabs for display customization: General, Advanced, Condition Banner, and Set Time &
Date.
General Tab - Customizing the Condition Banner
The General tab allows the user to define messages for each Condition Banner color.
Pressing anywhere in the colored region of the Condition Banner changes each
selection between Green, Yellow, Red, and Blue. By pressing on the colored region of
text, the on-screen keyboard pops up, enabling data entry. If User Defined Text (USER
TEXT) is Disabled, then data entry on the Condition Banner will not be permitted.
Change the User Defined Text to Enabled to change the text of each banner.
There are four Condition Banner colors available: Green, Yellow, Red, and Blue.
Figure 8: General Tab.
In the Setup Display General tab, you can configure the text to be displayed above and
below the center symbol by enabling the User Defined Text (USER TEXT). If you want
the banner to blink, enable the Blink (RED BLINK, GREEN BLINK, YELLOW BLNK,
BLUE BLINK) selection.
If any alarm occurs, the Condition Banner turns to red and the text above and below
the center symbol displays ALARM.
Advanced Tab - Customizing the Condition Banner
The Advanced tab allows you to make refinements in how information is displayed on
the Operating Condition section of the Home screen.The display contrast level is
adjusted using Adjust Contrast Level (CONTRAST), with selections from 1 to 4. After
modifying this parameter, press Save & Exit to view the brightness and contrast on the
Home screen display. Depending on the lighting and viewing conditions in the final
space, different contrast levels can improve readability of the SRCM.

Display Averaging (Tenths of Seconds)
Figure 9: Advanced Tab.
For passwords, the text displayed on the button is the action that takes place when
the button is pushed, not the status of the current setting.
Display Averaging (Tenths of Seconds)
This function helps 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 you require higher display resolution (four digits) but the ambient
pressure is unstable. By increasing the number (DISPLAY AVG), the effective number
of measured data points is increased and a weighted average is developed. Enter 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 final value in 2 seconds.
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 (PRESS.TOGGLE) displays on the Home
screen under normal operating conditions. This can be Primary Only, Secondary Only,
or Toggle depending on which room is most important for visual pressure verification.
If this is set to Secondary Only, then the Home screen displays 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 results in the error “Secondary Room source is NONE”.
If this is set to Toggle, then the Home screen displays the pressure value for both
rooms alternating back and forth momentarily (approximately 10 seconds apart). 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
which can be Enabled or Disabled.
Figure 10: Operator Password.
The Operator level allows access to change between Active 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 (OCC STATUS) from Active to Standby mode (where no alarms are
active). The Operator (Nurse or Lab Technician) can also respond to local audible and
visual alarms. 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 are made by
simply touching active areas of the display. If Operator Password (OPERATOR PSW)
is enabled, then a password will be needed before the change can be made.
Figure 11: Supervisor Password.
The Supervisor (SUPERV PSW) 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.

Set Time & Date Screen
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. It also sets the room mode (PPRES
MODE, SPRES MODE) to Positive, Negative or Neutral room.
Figure 19: Setup Alarm Screen.
Latch Alarm
(LATCH ALARM)
If enabled, this causes the display of red ALARM on the
Home screen to remain, even if the 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
(ALARM DELAY)
Time between when the pressure exceeding 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).

Set Time & Date Screen
Audible Alarm
(AUD. ALARM)
Enables or disables the audible buzzer. Regardless of
whether audible alarming is enabled or disabled, the red
ALARM condition displays on the Home screen,
annunciate to a Remote Annunciator, and propagate to
a configured Digital Output. If an alarm occurs and the
audible alarm is enabled, a new SILENCE button
displays 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
(MUTE T.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) (DI
STATUS)
Used for monitoring the door status—Open or Closed.
The DI is a Normally-Closed dry contact. A door jamb
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. The Door Alarm will suppress alarms if
they are generated at the same time that the door is
open.
Deadband (DEAD BAND)
Represents the region within the setpoint range where
yellow WARNING displays on the Home Screen to
indicate that the pressure is near ALARM limits. It is
adjustable from 0 to 10%. If set to 0, no WARNING
occurs, only ALARM when the pressure value reaches
setpoints. If set to any other value, WARNING will be
displayed if the pressure value reaches the percentage
of total pressure setpoint range.
When the unit goes outside of the deadband range, the
alarm occurs. The alarm remains on until the pressure
returns within the alarm limit range (or is
acknowledged—Latch Alarm), minus the setpoint.
Buzzer Volume
(BUZZER VOL.)
The buzzer volume can be adjusted from one to four,
with four being the highest sound level. The alarm
buzzer is disabled using the Audible Alarm Disabled
function.

The SRCM can configure the Room status to disable the Alarms when Door is open.
This function is used when there will be high traffic throughout the area and the User
wants to disable any alarms that are occurring because the Door is open. The alarms
are re-enabled once the Door is closed.
In the Setup Alarm screen, select the Digital Input (MV_11) choice to Door-!=Alarm.
Figure 20: Door Alarm Selection.
As shown in the screen below, DOOR (DI STATUS) is highlighted to indicate that the
door is open. However, the STANDBY (to the right of PRESSURE) indicates that the
room is in STANDBY mode.

Calibration and Self-Test
Calibration and Self-Test
This procedure is used for calibration of the internal pressure transducer sensor and
testing operation of hardware circuitry. Calibration is only required for highly accurate
measurement needs such as those needed to comply with federally mandated
regulations. Calibration must only be performed by qualified personnel. See SRCM
Room Pressure Monitor Technical Specification Sheet (149-211) for more information.
1. Select Primary or Secondary Room. When selected, the gray box to the right
indicates if the calibration will be applied to the on-board sensor or the external
sensor (Analog CH-1 or Analog CH-2). The indicated pressure is shown.
Figure 23: Calibration & Self Test Screen.
2. Calibration of the on-board sensor requires that the faceplate be removed and the
captive screw holding the display cover must be loosened (at the bottom-center of
the display bracket).
3. Lift the cover to expose the clear and red tubing connecting the on-board sensor to
the pressure fittings in the rear of the unit.
4. Remove the tubing from the high and low ports (red and clear tubing). This
disconnects the sensor from the room pressure.

Event Log
Event Log
The SRCM can be enabled with an audit trail of changes made to the
configurations/modes of the system by the Supervisor and Operator. When the
Supervisor or Operator changes any configuration using the menu, the action is
captured and stored in a string that includes the User Profile, Screen name where the
parameter was changed, Parameter name, and Value to which it was changed. There
are five such instances stored in non-volatile memory of the unit. Any power failure in
the unit will lose the data and it will be the responsibility of the BMS system to log
these strings after polling from the SRCM unit through BACnet. The SRCM unit will
store these strings as different instances of the Character String Object.
The value to which the parameter is changed is not logged for parameters such as
User-Defined Condition Banner Text, Room Label, Message Text, and so on, which
needs more memory. Other parameters whose variables are enumerated, real and
integer, are logged until the value is changed.
The string length of each instance of configuration change will be 50 Bytes in the data
memory area of the controller.
