Manual Conventions
The following table lists conventions to help you use this manual in a quick and efficient manner.
Convention Example
How To Use This Manual
Numbered Lists (1,2,3…) indicate a procedure with sequential steps.
Actions that you should perform are specified in boldface font.
Error and system messages are displayed in Courier New font.
New terms appearing for the first time are italicized.
Manual Symbols
The following table lists the symbols used in this Owner’s Manual to draw your attention to important information.
Notation Symbol Meaning
WARNING:
CAUTION:
1. Turn OFF power to the field panel.
2. Turn ON power to the field panel.
3. Contact your local Siemens Building Technologies representative. Type F for Field panels. Click OK to save changes and close the dialog box. The message Report Definition successfully renamed
appears in the status bar. The Open Processor continuously executes a user-defined set of
instructions called the control program.
Indicates that personal injury or loss of life may occur to the user if a procedure is not performed as specified.
Indicates that equipment damage, or loss of data may occur if the user does not follow a procedure as specified.
Datamate Software
Datamate is a customer software tool for all controller communications. There are two versions: Datamate Base, and Datamate Advanced. Datamate Base works on an IBM­compatible Personal Computer (PC), or a Handheld PC or Pocket PC™ running Windows CE. Datamate Advanced works only on an IBM-compatible Personal Computer. With Datamate, you can backup, restore, and edit any APOGEE database (but only Datamate Advanced allows you to edit points offline). Backing up and restoring a database can be accomplished while connected to any APOGEE field panel, or to the Building Level Network (BLN) or Floor Level Network (FLN) device in question. A modem and telephone lines can also be used. Databases can be saved to a hard or floppy disk and kept for permanent storage or used as backup.
For more information on Datamate software, refer to the appropriate user guide based on which version of Datamate you are using (Base or Advanced), or contact your local Siemens Building Technologies, Inc. representative.

LCD Messages
The LCD shows the differential pressure of the room in inches of H2O or Pascals. It also shows the status of the DPM with the following messages:
•
Liquid Crystal Display (LCD) Light Emitting Diodes (LEDs) (2)
• Horn Silence Button
• Portable Operator’s Terminal Port
• Pressure Mode Key Switch (optional)
•
Chapter 1 – Hardware
LCD Message… Indicates that the…
LOW PRESSURE room differential pressure is below the user-
defined limit.
HIGH PRESSURE room differential pressure is above the user-
defined limit.
DOOR OPEN door to the occupied space is open if it is being
monitored.
GENERAL FAILURE RPT has lost power or the DPM is not receiving
the pressure signal from the RPT.
SWITCH OVERRIDE database points that determine pressurization
mode have been set from a field panel. This overrides the pressure mode key switch position, rendering it ineffective.
ANTEROOM LCD is displaying the anteroom pressure in

function applies to Applications 702 and 704 when displaying the differential pressure of the anteroom:
Pressing the Horn Silence button for 5 seconds displays the “ANTEROOM” descriptor and the anteroom differential pressure on the LCD.
Pressure Mode Key Switch (Optional)
The Pressure Mode Key Switch (optional) allows the operator to locally select the pressure mode.
Remote Pressure Transmitter
The Remote Pressure Transmitter (RPT) is a Siemens Building Technologies, Inc. Laboratory Control product. The RPT ( between a room and the adjacent space. The RPT sends that measurement to the Differential Pressure Monitor.
