How to Use This Manual
The PresSura™Operation and Service Manual is divided into two parts. Part one describes how
the PresSura unit functions and how to interface with the device. This section should be read by
users, facilities staff, and anyone who requires a basic understanding of how the PresSura
controller operates.
Part two describes the technical aspects of the product which includes operation, calibration,
configuration, maintenance, and troubleshooting. Part two should be read by personnel
programming or maintaining the unit. TSI recommends thoroughly reading this manual before
changing any software items.
NOTE: This operation and service manual assumes proper PresSura controller installation.
Refer to the Installation Instructions to determine if the PresSura controller has been
properly installed.

User Basics

Part One
User Basics
Reading product manuals should not be a difficult and time-consuming process. This
section provides a brief but thorough overview of the PresSura product by maximizing
information with minimal reading. These few pages explain the purpose (The Instrument),
and the operation (Useful User Information, Digital Interface Module, Alarms) of the unit.
Technical product information is available in Part Two of the manual. The manual
focuses on hospital isolation rooms, but the product information is accurate for any room
pressure application.
The Instrument
PresSura Room Pressure Controller measures and reports “room pressure”. Proper
room pressure can control airborne contaminants that can adversely affect patients and
hospital staff. For example, tuberculosis (TB) isolation rooms need negative room
pressure (air flowing into the room), to minimize TB exposure to staff and other patients.
Conversely, surgical areas and bone marrow patient rooms need positive room pressure
(air flowing out of the room), to keep out contaminants that may adversely affect the
patient.
Room pressure, or pressure differential, is created when one space (hallway) is at a
different pressure than an adjoining space (patient room). When a pressure differential is
created between two spaces, air is forced to flow from the higher pressure space to the
lower pressure space. The direction of air flow is one component of proper room
pressure. The second component of room pressure is the speed or how fast is the air
moving between the two spaces. The PresSura controller provides both pieces of
information by measuring whether the air is flowing into or out of a room, and the speed
of the air.
Negative room pressure is present when air flows from a hallway / ante room into the
patient room. If air flows from the patient room into the hallway / ante room the room is
under positive pressure. Figure 1 gives a graphic example of positive and negative room
pressure.
Figure 1: Room Pressure

2
An example of negative pressure is a bathroom with an exhaust fan. When the fan is
turned on, air is exhausted out of the room creating a slight negative pressure in the
bathroom compared to the hallway. This pressure differential forces air to flow from the
hallway into the bathroom.
The PresSura device informs the staff when the room is under proper pressure, and
provides alarms when the room pressure is inadequate. If the room pressure is in the
safe range, a green light is on. If the pressure is inadequate, a red alarm lights and
audible alarm turns on.
The PresSura controller consists of two pieces: a pressure sensor and a Digital Interface
Module (DIM). The pressure sensor is mounted above the doorway entrance to the
isolation room. Usually the DIM is mounted near the entrance to the isolation room or at
the nursing station. The pressure sensor continuously measures the room pressure and
provides room pressure information to the DIM. The DIM continuously reports the room
pressure and activates the alarms when necessary. PresSura Room Pressure Controller
is a continuous measuring system providing instant information on the room pressure.
Useful User Information
The DIM has a green light and red light to indicate room pressure status. The green light
is on when the room has proper room pressure. The red light comes on when an alarm
condition exists.
Sliding the door panel to the right reveals a digital display and keypad (Figure 2). The
display shows detailed information about room pressure, alarms, etc. The keypad allows
you to test the device, and program or change the device parameters.
Figure 2: Digital Interface Module (DIM)
PresSura controller has two levels of user information:
1. PresSura controller has a red light and green light to provide continuous
information on room pressure status.
2. PresSura controller has a hidden operator panel providing detailed room
status information, self-testing capabilities, and access to the software
programming functions.
NOTE: The unit provides continuous room pressure status through the red and green
light. The operator panel is normally closed unless further information on room
pressure status is needed, or software programming is required.

User Basics

Operator Panel
The DIM in Figure 3 shows the location of the digital display, keypad and lights. An
explanation of the operator panel follows the figure.
Figure 3: PresSura Operator Panel - Open
Green / Red light
The green light is on when all the conditions for proper room pressure are adequate. This
light indicates the isolation room is operating safely. If any of the room pressure
conditions cannot be satisfied the green light turns off, and the red alarm light turns on.
Operator Panel
A cover hides the operator panel. Sliding the door panel to the right exposes the operator
panel (Figure 2).
Digital Display
The alphanumeric digital display is a two line display that indicates actual room pressure
(positive, negative or no isolation), alarm status, menu options, and error messages. In
normal operation (green light is on), the display continuously scrolls information about
room pressure, and other variables programmed; flow, air changes per hour, etc. The
variables that scroll depend on the model of PresSura controller purchased and options
installed.
As an example, if an alarm condition occurs, the variable that normally scrolls
PRESSURE PRESSURE
NORMAL will change to read ALARM = *
* will state type of alarm; low pressure, high pressure, flow
When programming the unit, the display will change and now show menus, menu items,
and current value of the item, depending on the specific programming function being
performed.
Keypad
The keypad has six keys. The gray keys with black letters are user information keys. In
normal operation these keys are active. The gray keys with blue characters are used to
program the unit. The red emergency key has no function on the monitor and has been
disconnected. A thorough description of each functioning key is given below.

4
User Keys - Gray with Black Letters
The four keys with black letters provide information without changing the operation or the
function of the unit.
TEST Key
The TEST key initiates an instrument self-test. Pressing the TEST key activates
a scrolling sequence on the display that shows the product model number,
software version, and alarm values. The unit then performs a self test that tests
the display, indicator lights, audible alarm, and internal electronics to ensure they
are operating properly. If a problem with the unit exists, “DATA ERROR” will be
displayed. You should have qualified personnel determine the problem with the
unit.
RESET Key
The RESET key performs two functions. 1) Resets the alarm light, alarm
contacts, and audible alarm when in a latched or non automatic reset mode. The
room pressure must be in the safe or normal range before the RESET key will
operate. 2) Clears any displayed error messages.
MUTE Key
The MUTE key temporarily silences the audible alarm. The time the alarm is
temporarily silenced is programmable by you (see MUTE TIMEOUT). When the
mute period ends, the audible alarm turns back on if the alarm condition is still
present. NOTE: You can program the audible alarm to be permanently turned off
(see AUDIBLE ALM).
AUX Key
The AUX key is active only in specialty applications and is not used on the
standard PresSura controller. If the AUX key is used, a separate manual
supplement will explain the AUX key function.
Programming Keys - Gray with Blue Characters
The four keys with blue print are used to program or configure the unit to fit a particular
application.
WARNING: Pressing these keys will change how the unit functions, so please
thoroughly review the manual before changing menu items.
MENU Key
The MENU key performs three functions. 1) Provides access to the menus when
in the normal operating mode. 2) When the unit is being programmed, the MENU
key acts as an escape key to remove you from an item or menu, without saving
data. 3) Returns the unit to the normal operating mode. The MENU key is further
described in the Software Programming section of this manual.
SELECT Key
The SELECT key performs three functions. 1) Provides access to specific
menus. 2) Provides access to menu items. 3) Saves data. Pressing the key when
finished with a menu item will save the data, and exit you out of the menu item.
/Keys
The /keys are used to scroll through the menus, menu items, and through
the range of item values that can be selected. Depending on the item type the
values may be numerical, specific properties (on / off), or a bar graph.

User Basics
5
Alarms
PresSura controller has visual (red light) and audible alarms to inform you of changing
conditions. The alarm levels (set points) are determined by hospital personnel, which
could be the infection control group, charge nurse, or a facilities group depending on the
hospital organization.
The alarms, audible and visual, will activate whenever the preset alarm level is reached.
Depending on the PresSura model installed, programmed alarms will activate when room
pressure is low or inadequate, when room pressure is high or too great, or when the
supply or exhaust air flow is insufficient. When the isolation room is operating safely, no
alarms will sound.
Example: The low alarm is preset to activate when the room pressure reaches -0.001
inches H2O. When the room pressure drops below -0.001 inches H2O (gets
closer to zero), the audible and visual alarms activate. The alarms turn off
(when set to unlatched) when the unit returns to the safe range which is
defined as negative pressure greater than -0.001 inches H2O.
Visual Alarm Operation
The red light on the front of the unit indicates an alarm condition. The red light is on for all
alarm conditions, low alarms, and high alarms.
Audible Alarms
The audible alarm is continuously on in all low and high alarm conditions. The audible
alarm can be temporarily silenced by pressing the MUTE key. The alarm will be silent for
a period of time (see MUTE TIMEOUT to program time period). When the timeout period
ends, the audible alarm turns back on if the alarm condition is still present.
You can program the audible alarm to be permanently turned off (see AUDIBLE ALM).
The red alarm light will still turn on in alarm conditions when audible alarm is turned off.
The audible and visual alarms can be programmed to either automatically turn off when
the unit returns to the safe range or to stay in alarm until the RESET key is pressed (See
ALARM RESET).

Part Two
Technical Section
The PresSura controller is ready to use after being properly installed. The pressure
sensor is factory calibrated prior to shipping, and should not need adjustment. The Digital
Interface Module (DIM) is programmed with a default configuration that can be easily
modified to fit your application.
The Technical section is separated into five parts that cover all aspects of the unit. Each
section is written as independently as possible to minimize flipping back and forth
through the manual for an answer.
The Software Programming section explains the programming keys on the DIM. In
addition, the programming sequence is described, which is the same regardless of the
menu item being changed. At the end of this section is an example of how to program
the DIM.
The Menu and Menu Item section lists all of the software items available to program and
change. The items are grouped by menu which means all calibration items are in one
menu, alarm items in another, etc. The menu items and all related information including
programming name, description of menu of item, range of programmable values, and
how the unit shipped from the factory (default values). This manual covers two models.
The features unique to the premium unit are highlighted in Figure 6, and are identified
as Premium model only items.
The Calibration section describes the required technique to compare the pressure
sensor reading to a thermal anemometer, and how to adjust the zero and span to obtain
an accurate calibration. This section also describes how to zero a TSI flow
station transducer.
The Maintenance and Repair Part section covers all routine maintenance of equipment,
along with a list of repair parts.
The Troubleshooting section is split into two areas: Mechanical operation of the unit and
system performance. Many external variables will affect how the unit functions so it is
critical to first determine if the unit is having mechanical problems - i.e., no display on
unit, remote alarms don’t function, etc. If problems still exist, look for performance
problems (i.e., doesn’t seem to read correctly, display fluctuates, etc.). The first step is to
determine that the system is mechanically operating correctly, followed by modifying the
configuration to eliminate the performance problems.

Software Programming
Programming the PresSura Room Pressure Controller is quick and easy if the
programming keys are understood, and the proper key stroke procedure is followed. The
programming keys are defined first, followed by the required keystroke procedure. At the
end of this section is a programming example.
NOTE: It is important to note that the unit is always operating when programming. When
a menu item value is changed, the new value takes effect immediately after
saving the change, not when the unit returns to normal operating mode.
This section covers programming the instrument through the keypad and display.
If programming through RS-485 communications, use the host computer’s
procedure. The changes take place immediately upon saving data in the
instrument.
Programming Keys
The four keys with blue characters (refer to Figure 4) are used to program or configure
the unit to fit your particular application. Programming the instrument will change how the
unit functions, so thoroughly review the items to be changed.

MENU Key
The MENU key has three functions.
1. The MENU key is used to gain access to the menus when the unit is in
the normal operating mode. Pressing the key once will exit the normal
operating mode and enter the programming mode. When the MENU
key is first pressed, the first two menus are listed.
2. When the unit is being programmed, the MENU key acts like an escape
key.
- When scrolling through the main menu, pressing the MENU key will
return the unit to standard operating mode.
- When scrolling through the items on a menu, pressing the MENU
key will return you to the list of menus.
- When changing data in a menu item, pressing the MENU key will
escape out of the item without saving changes.
3. When programming is complete, pressing the MENU key will return the
unit to normal operating mode.

Technical Section

flashing cursor on the desired menu. Press the SELECT key to select
the menu. The first line on the display will now be the selected menu,
and the second line will show the first menu item.
2. The SELECT key is used to gain access to specific menu items. To
access a menu item scroll through the menu items until item appears.
Press the SELECT key and the menu item will now appear on the first
line of the display, and the second line will show the item value.
3. Pressing the SELECT key when finished changing an item will save the
data, and exit back to the menu items. An audible tone (3 beeps) and
visual display (“saving data”) gives confirmation data is being saved.
/Keys
The /keys are used to scroll through the menus, menu items, and through
the range of item values that can be selected. Depending on the item type the
values may be numerical, specific properties (on / off), or a bar graph.
NOTE: When programming a menu item, continuously pressing the arrow key
will scroll through the values faster than if arrow key is pressed and
released.
Keystroke Procedure
The keystroke operation is consistent for all menus. The sequence of keystrokes to
follow is the same regardless of the menu item being changed.
1. Press the MENU key to access the main menu.
2. Use the /keys to scroll through the menu choices. The blinking cursor needs
to be on the first letter of the menu you want to access.
3. Press the SELECT key to access chosen menu.

Menu and Menu Items
The PresSura controller is a very versatile device which can be configured to meet your
specific application. This section lists all of the menu items available to program and
change (except diagnostics menu). Changing any item is accomplished by using the
keypad, or if communications are installed through the RS-485 Communications port. If
you are unfamiliar with the keystroke procedure please see Software Programming for a
detailed explanation. This section provides the following information:
- Complete list of menu and all menu items
- Gives the menu or programming name
- Defines each menu item’s function; what it does, how it does it, etc.
- Gives the range of values that can be programmed
- Gives default item value (how it shipped from factory)
The menus covered in this section are divided into groups of related items to ease
programming. As an example all calibration items are in one menu, alarm information in
another, etc. The manual follows the menus as programmed in the monitor. The menu
items are always grouped by menu and then listed in menu item order, not alphabetical
order. Figure 5 shows a chart of all Model 8630-SM standard monitor menu items. Figure
