User Basics 3
Part One
User Basics
This section is designed to provide a brief but thorough overview of the product installed. These
few pages explain the purpose (The Instrument) and the operation (Useful user information,
Operator panel, Alarms) of the product. Technical product information is available in Part Two of
the manual.
The Instrument
The Model RPM10 and RPM20 Monitors are designed to measure and report room pressure
differential in health-care facilities and other critical environments. They also can measure other
parameters, such as supply flow, exhaust flow, relative humidity, and room temperature.
Useful User Information
The display of the monitor is colored gray, green, or red. Green indicates the room pressure
differential and other configured measurements are adequate. The display turns red to indicate
alarm status when the room pressure differential or another configured measurement has risen
above or dropped below a safe level. The display provides additional information depending on
the configuration of the unit. Gray indicates that the room is in no isolation mode and will not
alarm if room pressure differential is not maintained.
Operator Panel
The Model RPM10 and RPM20 Room Monitors are easy to use. Normal vs. alarm condition and
room modes are always shown on the display. In addition, the displayed can be configured to
show the room pressure differential or all measurements. Specific details about the front panel
display and controls are described on the following pages. The front panel, shown in Figure 1 and
Figure 2 identifies the important features on the display:
Figure 1. Single Room Screen

4 Part One
Figure 2. Two Room Screen
Display Screen
The LCD display is highly configurable and can display various critical information including
pressure differential, flow rate, alarm status, menu options, and error messages. In addition, the
LCD display is used for programming the unit. When programming the unit, the display will show
menus, menu items, and current value of the menu item, depending on the specific programming
function being performed.
Room Indicator Colors
Green
The screen icon is colored green (NORMAL) when the room pressure and/or other
configured measurements are adequate. This light indicates the room is operating
safely. If a set point cannot be maintained or an alarm limit has been reached, the
green light turns off and the red alarm light turns on.
Red
The room icon is colored red (ALARM) when the room pressure and/or other
configured measurements are not within alarm limits. This light indicates the room is
not operating safely. The display screen will also indicate the type of alarm or an
emergency message.
Gray
The room icon is colored gray to indicate No Isolation mode. In No Isolation mode
the Model RPM10 and RPM20 will not alarm.
Operator Keys
The following keys appear on the display of the Model RPM10 and RPM20 room monitor:
MUTE key
The MUTE key silences an audible alarm. The alarm remains silent until the
MUTE TIME value has been reached or the unit returns to control set point.
ACKNOWLEDGE key
The ACKNOWLEDGE key clears alarms when the Model RPM10 and RPM20
have been set latched alarms under the ALARM RESET item.

User Basics 5
USB Port
There is a USB port on the case. This USB port can be used with TSI’s Configuration Software.
Figure 3. USB Port Location
Alarms
The Model RPM10 and RPM20 monitors have visual (red light) and audible alarms to inform you
of changing room conditions. The alarm levels (set points) are determined by facilities staff, which
could be Engineering, Industrial Hygiene, or a facilities group depending on how the safety staff
is organized.
The audible and visual alarms will activate whenever the field configured alarm level is reached.
The alarms will activate if the room pressure differential is low or inadequate, high or too great, or
when the airflow is too low or too high (need optional flow device installed). When the room is
operating safely, no alarms will sound.
Example: The low alarm is preset to activate when the room pressure differential falls below -
0.01 in H2O (closer to neutral). When the room pressure drops to -0.005 in H2O, for
example, 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 0.001 in H2O
greater than alarm set point (-0.01 in H2O).
Visual Alarm
The display of the monitor turns red to indicate an alarm condition. The icon turns continuously
red for all alarm conditions.
Audible Alarms
The audible alarm is continuously on in all low and high alarm conditions. The audible alarm can
be silenced by pressing the key.
If the audible alarm has been muted, the alarm is silenced for a configurable period of time (see
menu item MUTE TIME) or the measurement returns to the safe range. The safe range is
0.001 in H2O (50 cfm) above the low alarm set point and 0.001 in H2O (50 cfm) below the high
alarm set point.

6 Part One
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 key is pressed (See menu item
ALARM RESET).
Alarm Relays
The PresSura monitors feature 2 alarm relays. The alarm relays can be field configured to either
open or close to indicate an alarm condition, although they will close on loss of power.
Relay 1 functions as the low alarm relay, and will activate after the alarm delay for low pressure,
low flow, low temperature and low RH alarms. Relay 1 will trigger without waiting for the alarm
delay to indicate a LOM alarm, or low pressure drop across a venturi valve, if a flow input is
configured for venturi valves.
Relay 2 is field-configurable to function as a high alarm relay or to indicate the room status. Refer
to the Relay 2 Out item in the Alarm Config menu for details on this operation.

Technical Section 7
Part Two
Technical Section
The PresSura™Room Pressure Monitor is
ready to use after being properly installed and
configured. The TSI through-the-wall sensor is
factory calibrated, as are most pressure
transducers. Figure 4 shows the Digital Interface
Module (DIM) which 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.
Figure 4. PresSura Room Pressure Monitor
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 Items section lists all of the software items available to program and
change. The items are grouped by menu which means all set points are in one menu, control
signal items in another, etc. The menu items and all related information is provided including;
programming name, description of menu item, range of programmable values, and how the unit
shipped from the factory (default value).
The Calibration section describes the required procedure to calibrate the controller. This section
explains how to compare the controller’s reading to a portable thermal anemometer and then
adjust the span to establish an accurate calibration. This section also describes how to zero a
TSI flow station transducer (if installed).
The Maintenance and Repair Parts 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 system is having mechanical problems—i.e., no display on unit, alarms do not
function, , etc. If no mechanical problems exist, look for performance problems (i.e., does not
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.

8 Part Two
Software Programming
Programming the PresSura Model RPM10/RPM20 monitor is quick and easy if the proper
keystroke 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 network communications (see Appendix B), use the host
computer’s procedure. The changes take place immediately upon saving data in the
instrument.

Menu and Menu Items
The PresSura Model RPM10 and RPM20 monitors are very versatile devices 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 items is accomplished by using the
touchscreen or through communications with the Building Automation System. If you are
unfamiliar with the keystroke procedure please see Software Programming section for a detailed
explanation. This section provides the following information:
Complete list of menus 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 set points are in one menu, alarm information in another, etc. The manual
follows the menus as programmed in the controller. The menu items are always grouped by
menu and then listed in menu item order, not alphabetical order.
Figure 11 and Figure 12 show the PresSura Model RPM10 and RPM20 monitor menu items.
