A “home” for your OMA-D560
Your new OMA-D560 should be located in a convenient location close to the conditions being monitored - in a
warehouse, basement, utility closet or other work area, mounted on a wall, or mounted inside an equipment cabinet.
When mounted in an optional NEMA-4X weatherproof enclosure, the OMA-D560 can be used in damp or dusty
environments or placed outdoors.
If the outputs of the OMA-D560 are used to switch voltages in excess of 30 volts, the unit must be mounted in an
approved electrical equipment enclosure.
Connecting a Phone Line
The OMA-D560 is designed to work on most public phone systems found throughout the world. It will also work
on most office PBX phone systems. With optional equipment, it will also work on cellular phone systems and with
low-orbiting satellites.
www.omega.com
2
Standard Phone Lines
For your convenience, the OMA-D560 has a dual phone jack. You must attach the telephone line to the jack
labeled “LINE”. You can also attach a standard telephone to the jack labeled “PHONE”. It is recommended
that you use this standard telephone to check the phone line for dial tone and the ability to make incoming and
outgoing phone calls.
Cellular Phones
The OMA-D560 will also work with North American analog cellular phones equipped with a dial-tone adapter.
Contact technical support for details.
Connecting a Power Source
The OMA-D560 is factory configured to operate on 110 VAC 50/60 Hz OR 220 VAC 50/60 Hz. It can also operate
from 12 VDC.
AC Operation
Plug the OMA-D560’s power cord into a properly grounded (three-wire) electrical outlet. The power required
by the OMA-D560 is 20 watts plus the wattage of the load (if any) attached to the “AC Switched Output”
connector.
DC Operation
Connect the positive lead of a 9 to 15 VDC source to the “DC IN” terminal and connect the negative lead to the
“Common” terminal.
IMPORTANT: When using DC power, the OMA-D560’s AC power cord MUST be disconnected AND its
backup battery MUST be disabled by removing the jumper from between the “BATT OUT” and “DC IN”
terminals.
Solar Operation
The OMA-D560 can be powered by a properly sized solar panel. Contact technical support for details.
Backup Battery
The OMA-D560 system has an internal rechargeable battery that maintains full operation in the event of a power
outage. This battery must be enabled when the unit is put into service and disabled when taken out of service. All
information programmed into the OMA-D560 system will be retained whether or not the battery is connected to the
system.
NOTE: An auxiliary DC power output on the OMA-D560 system can be used to power external sensors and
accessories. It provides 12 volts DC (nominal) at up to 200 mA. This power is taken from the OMA-D560 system’s
backup battery and will provide uninterruptible power, even during a power outage.
Enabling the Backup Battery
Attach the shorting clip (included with the unit) between the “BATT OUT” and “DC IN” terminals. If the
shorting clip is lost, a short length of wire can be used. Once enabled, the battery will require up to 24 hours to
fully charge.
OMEGA ENGINEERING, INC.
Disabling the Backup Battery
To disable the backup battery, remove the shorting clip from between the “BATT OUT” and “DC IN”
terminals.
Testing the Backup Battery
When operating from AC power, the power light on the front panel of the OMA-D560 system is green. When
operating from battery, the power light is red.
Test the battery at least once per year by removing the OMA-D560’s AC power source for 10 to 15 minutes
and verifying that the power light changes to red and that the unit responds to an incoming phone call.
Attaching the Inputs
The OMA-D560 system supports eight universal inputs that can accept a variety of input types.
Inputs 1 through 4 are factory pre-configured to accept 4-20 mA signals while inputs 5 through 8 are factory preconfigured to accept dry-contact signals. It is easy to re-configure an input to accept 4-20 mA, 0-5 VDC,
thermistor, logic-level, dry-contact or other signal types in any combination.
3
DIP Switch Settings
Removing the input connector reveals two banks of DIP switches as illustrated in the figure below. Each bank
has eight switches labeled 1 through 8 corresponding to inputs 1 through 8. The upper bank controls 200-ohm
shunt resistors (required for current monitoring applications) while the bottom bank controls pull-up resistors
(required for temperature monitoring and dry-contact applications.

Communications
This section describes the procedure for establishing communication with a
OMA-D560 system. It includes details on how to use the RS-232 port, a phone
line for data, voice and pager communication, and how to put data into the web.
Using a Phone Line
Data, voice or pager? It’s your decision!
The OMA-D560 system can communicate over a standard phone line with a computer or pager. It also offers a
powerful, easy-to-use voice mode for ready-access to information from your equipment anytime, from any standard
telephone.
The data mode will allow you to review inputs, set up and reconfigure any OMA-D560 system from a remote
location, retrieve stored information, and perform diagnostics from your PC.
The voice mode offers the convenience of inquiry into condition status from any standard telephone, and provides a
high-quality, clear, consistent voice without the need for set up, programming, or recording.
IMPORTANT
℡
Voice Mode
℡
The OMA-D560 will respond to your call by generating a carrier tone − indicating that the
system is attempting to communicate with a data terminal. The tone will eventually stop after a
few seconds and the OMA-D560 will switch to voice mode and speak in a synthesized voice:
“Hello, this is telephone number five, five, five, one, two, one, two. Enter security code.”
Enter your eight-digit security code on the touch-tone keypad (initially set at the factory to 1, 1, 1, 1, 1,
1, 1, 1). The OMA-D560 system will respond “OK.”
The voice mode of the OMA-D560 system utilizes a built-in voice enunciator that responds to commands
entered from any standard push-button tone-dialing telephone. You enter command codes from the
telephone keypad and response messages are spoken in English.
Voice Mode commands consist of a three-letter code followed by either the # or * key. The following
commands are available in the Voice Mode:
ALM# = Alarm acknowledge
B Y E # Terminate on-line session
Information intended exclusively for voice-mode users is
highlighted in this guide by a telephone icon and use of this
different type face
OMEGA ENGINEERING, INC.
I N P # Input report
O U T # Output report
P H O # Change dial-out phone number
T I M # System time report
For example, typing INP# initiates an INPut report:
INP
GHI4MNO6PQR
To end a voice mode session, simply type BYE#.
Modem Mode
You can communicate with the OMA-D560 system using a PC with a modem and any popular communications
program having terminal emulation capability. One such communications program is “Hyperterminal”, a
program that is included free with the Microsoft Windows 95, 98, 2000 & NT 4.0 operating systems.

Since HyperTerminal is used throughout this manual to illustrate data mode operation, detailed instructions on
its use are included in this section.
Defining a HyperTerminal Connection
To use HyperTerminal, you must first define a few parameters including the phone number of the OMA-D560.
To start HyperTerminal, click Start, and then click Programs, Accessories and Hyperterminal. Look for an
icon labeled HyperTerminal or Hypertrm.exe and click on it.
In the Connect Description box, type a name for the connection, choose an icon, then click OK.
In the Connect To box, enter the country/region, area code and phone number of the unit to be called and
choose your computer's modem from the Connect Using list (Note: if your modem is not listed in the Connect
Using list, it may not be installed properly). Click OK.
Click the Dialing Properties button to view information about the location of your computer. You may not
have to make any changes to this box, but make sure the information is correct. If your modem is attached to an
office phone system, you may need to enter a code (such as “9”) to access an outside line. Verify that the
Number to be dialed in the lower left corner of the box appears exactly as it would if you were to dial the
OMA-D560 from your telephone. It must not include any extraneous numbers. Click OK.
Click Properties, Configure, Connection, Advanced and make sure that Use Error Control is not checked.
In the Connect box, click Cancel. It is now time to save your settings and exit the program. On the
HyperTerminal menu bar, select File, Save and then File, Exit.
Establishing Communication
Once you’ve defined a connection to your OMA-D560, establishing communications with it is as simple as
clicking on an icon.
Start HyperTerminal by clicking Start, Programs, Accessories and Hyperterminal. Look for the OMA-D560
connection that you've created and click on it.
When HyperTerminal starts, you will see the connection information in the Connect box. Click Dial. You may
hear dialing tones or pulses followed by a “ring” sound, followed by modem tones, then a connection. Once a
connection is established, the Connect box will close and the main HyperTerminal screen will become active.
www.omega.com

If HyperTerminal fails to connect, re-check your settings (making sure that Use Error Control is not checked)
and try again.
The OMA-D560 will prompt you to enter a security code. You must enter a valid security code within 30
seconds or the OMA-D560 will terminate the connection. If you don’t know the security code, try the factory
default security code, “11111111” (eight ones) followed by Enter.
Once you have gained access, you can enter commands and the OMA-D560 will respond. The commands to
access the system are simple three-letter codes (e.g. INP = input, ALM = alarm, PHO = telephone), generally
followed by a fourth letter (e.g. R = report, S = set).
You may enter a command whenever the “COMMAND>” prompt is displayed.
If you press Enter at the command prompt, you’ll get a complete listing of commands. The most common
commands are INP R (input status report), ALM R (alarm report) and SEC R (security report).
If an incorrect command is entered, you will receive an “Invalid Command” message.
In the following sections of this manual are step-by-step procedures that will help you prepare the OMA-D560
system to work for you - describing how to designate individuals you want to receive alarm messages, set low
and high alarm set-points, etc.
Internet Access
An optional internet service is available that will generate detailed daily reports based on information collected by
your OMA-D560 and post those reports to a website. Contact customer service for additional information.
Using the RS-232 Port
Attach a “straight-through” serial cable from your PC’s COM port to the RS-232 port on the front panel of the
OMA-D560 system.
Follow the procedure outlined in “Modem Mode” (above) to define a HyperTerminal connection, substituting your
PC’s COM port for the modem in the Connect Using list then click Configure and enter the following settings:
Bits per second: 4800
Parity: none
Stop bits: 1
Flow control: None.

Commissioning Checklist
The commissioning process tailors the OMA-D560 system to your unique remote
monitoring application. This section outlines the minimal commissioning tasks
required for many applications. Complete details relating to the commands
mentioned in this section are discussed in further detail in the COMMAND
REFERENCE section later in this manual.
IMPORTANT: The OMA-D560 remote monitoring system has many time and
money-saving capabilities that can only be realized after having a thorough
working knowledge of all of the commands described in the COMMAND
9
REFERENCE section in this manual.
Identify the System
The OMA-D560 has several programmable fields to help identify it in both voice and data modes. These fields
include “site name” and “code number” (for data mode identification) and “unit phone number” (for voice
mode identification).
The information that you enter in these fields will not affect the operation of the unit but will help you manage
information from your remote sites.
Use the SEC S command to enter system identification information (refer to the Command Reference section).
Configure the Inputs
The OMA-D560 accepts a variety of different input types.
Use the INP S command to instruct the OMA-D560 as to how to interpret and report this input data (refer to
the Command Reference section).
Configure the Data Logger
The OMA-D560’s data logger can be configured to take periodic “snapshots” of designated inputs and/or
record system events and alarm conditions.
Use the LOG S command to set logging parameters (refer to the Command Reference section).
www.omega.com
10
Configuring the Alarm Dialer
The OMA-D560 system continually monitors all inputs for alarm set-points that have been violated. If a setpoint has been exceeded for a designated period of response time, the OMA-D560 system recognizes this as the
existence of an alarm condition.
It will send the message to up to eight designated telephone numbers anywhere on or off site and at any time. If
the calls are unanswered, the OMA-D560 system will wait a pre-set length of time and perform the complete
dial-out sequence again.
The alarm dial-out sequence will continue − even if the alarm condition has cleared − until the alarm has been
externally acknowledged.
To fully configure the alarm dialer, use the INP S command to set the alarm set-points and the PHO O
command to program the dialing directory (refer to the Alarm Handling and Command Reference sections).
Configuring the Output Controller
The OMA-D560 system can automatically control loads in response to input set-points or alarm conditions.
To configure the output controller, use the INP S command to set the control set-points and the OUT S
command to define the control mode (refer to the Output Control and Command Reference sections).
OMEGA ENGINEERING, INC.
Operation
Reports
The OMA-D560 generates a variety of concise text reports. Each report is updated just prior to generation and is
time-stamped. An auto-report feature, when enabled, produces an input report at the beginning of each
communication session without the need to enter a pass code. Reports can be accessed by any security level.
Input Report
To get a report of the present condition of the eight inputs, including any that may have exceeded an alarm setpoint, type INP R at the command prompt.

Alarm Handling
The OMA-D560 system constantly monitors all inputs to determine if alarm set-points have been violated. If a setpoint has been violated for a specified amount of response time, an alarm condition exists.
This alarm condition will continue until the input has returned to normal and has been externally acknowledged.
When an alarm occurs and the response time has expired, the OMA-D560 system will begin its dial-out sequence.
The OMA-D560 system can deliver an alarm in voice or data mode.
The OMA-D560 system will dial each number in succession. If the alarm is not acknowledged, the OMA-D560
system will wait a specified alarm dial-out interval and then start another dial-out sequence with the same alarm
message.
Alarms can be acknowledged in either data or voice mode.
There are two classes of alarms -
Active acknowledged alarms: The input continues to violate an alarm set-point but an operator has acknowledged
the condition. The OMA-D560 system continues to recognize the alarm condition but will not attempt to make an
outgoing phone call.
13
Unacknowledged alarms: Any alarms which have not been acknowledged. An unacknowledged alarm initiates an
alarm dial-out sequence.
Responding to an Alarm Message
An alarm can be acknowledged by pressing the ALARM CANCEL switch on the front panel of the OMAD560 system. You can also acknowledge and alarm through the serial port or modem by issuing the ALM R
command.
The front panel indicator will remain on continuously when the alarms are acknowledged.
℡
When an alarm is delivered in voice mode, the OMA-D560 system will repeat the alarm
message up to six times:
“Hello, this is telephone number one two three four five six seven. Alert condition exists.”
Recipients of such calls should press and hold any keypad button for one to two seconds. The OMA-D560
system will respond with the following message:
“OK. Enter security code.”
When a correct security code has been entered, the OMA-D560 System will acknowledge it, saying, “OK” You
can now enter INP R to learn the cause of the input alarm condition and enter ALM# to acknowledge receipt of
the alarm message.
℡
To acknowledge an alarm and prevent the OMA-D560 system from dialing out again until
new alarm conditions exist, type ALM#.

Output Control
The OMA-D560 includes a straightforward output controller that enables you to
activate or reset equipment remotely on demand or automatically in response to
input set-points or alarm conditions.
Configuring an Output
Each output has several parameters that define how and when they will activate. To check or modify these
parameters, type OUT S and select an output.
COMMAND>OUT S

0 = Previous Menu
Choose a Number>
Label
A label is a short descriptive name that you assign to each output. By typing =HIDE=, you are able to remove
an output from all reports (although it will continue to operate). To bring the input "out of hiding," simply enter
a new label for that output.
On Time per Minute
This parameter is used to 'throttle' an output (rather than have it constantly on or off). If an output has been
turned on, and this parameter is set for 40, then the output will cycle on for 40 seconds and off for 20 seconds
(ad infinitum). If the parameter is set for 60, the output remains on constantly. The minimum value is one. The
default value is 60 seconds. This feature is useful when controlling heaters and chemical feed pumps.
OMEGA ENGINEERING, INC.
Control Mode
The output controller has several modes of operation that can be grouped into three categories: Manual,
Automatic and Alarm. In manual mode, an output is controlled by commands issued by the user. In automatic
mode, an output is controlled by “on” and “off” set-points on a designated input channel. In alarm mode, an
output is controlled by the alarm status of the OMA-D560. You can mix or match control mode settings among
the four output channels.

Manual Control
Manual control permits an operator to remotely control the on/off state of the four output relays.
15
Automatic - Day and Night
The output will automatically turn ON or OFF as determined by the Output OFF and Output ON control setpoints on its corresponding input. Use the INP S command to set or change the control set-points.
Automatic - Night
Identical to “Automatic – Day and Night”, except that control only occurs during nighttime hours. The output is
off during daytime hours. Use the INP S command to set or change the control set-points and the DAY S to set
or change “Day Start Time” and “Day Stop Time”.
Automatic - Day
Identical to “Automatic – Day and Night”, except that control only occurs during daytime hours. The output is
off during nighttime hours. Use the INP S command to set or change the control set-points and the DAY S to
set or change “Day Start Time” and “Day Stop Time”.
Momentary
When an output defined as “Momentary” is toggled “on”, it will stay “on” for a defined period of time them
return to the “off” state.
Close - Present Alarms
The output will go on (close) when an alarm condition presently exists on any of the inputs designated by the
alarm mask. A present alarm is considered to be active when an input alarm set point is exceeded for longer
than the input’s response time.
Open on Present Alarms
The output will go off (open) when an alarm condition presently exists on any of the inputs designated by the
alarm mask. A present alarm is considered to be active when an input alarm set point is exceeded for longer
than the input’s response time.
www.omega.com
16
Close on Unacknowledged Alarms
The output will go on (close) when an alarm condition exists on any of the inputs designated by the alarm
mask, and stay on even if the alarm condition goes away. It will turn off (open) when the alarm condition is
acknowledged.
Pulse Width
When the momentary output control mode is selected, this parameter specifies the width of the momentary
output pulse.
Power-up State
By default, all outputs are off after a power-up reset. By changing the Power-up State setting to On, you can
have an output turn on immediately after a reset.
Alarm Mask
When using one of the alarm modes to control an output, you must enter an alarm mask for that output. The
alarm mask indicates which input’s alarm conditions should be used to control the output. The alarm mask is a
two character hexadecimal number representing an eight bit binary mask. The least significant bit of the mask
correlates to input #1, the most significant bit of the mask correlates to input #8. If a bit in the mask is set to 0,
alarms on the correlating input will not control the output. Conversely, if a bit is set to 1, an alarm on the
correlating input will control the output.
As an example, if you want output #1 to be controlled by alarms on input channels 1 through 4, but ignore
alarms on channels 5 through 8, you would use 0F (equivalent to binary 00001111) as the alarm mask.
Call the Technical Support Hotline if you are unfamiliar with hexadecimal notation.
Controlling an Output
If an output is configured as manual or momentary, it can be interactively controlled in either voice or data
mode.
In data mode, use the OUT O command and select the channel you want to control then use the spacebar to
manually toggle the output “on” or “off”.
℡
In voice mode, the on/off state of the output is controlled by the operator with the On1# and
On0# commands. Entering On1# turns output “n” ON and On0# turns output “n” OFF, where “n”
is the desired output number (1-4).
EXAMPLE: To turn output three OFF, press “0”, “3”, “0”, “#” on the phone keypad. To turn output
three ON, press “0”, “3”, “1”, “#” on the phone keypad.

Data Logging/Trending
It is often desirable to track conditions (such as tank level or ambient air
temperature) over extended periods of time. The OMA-D560 system provides
this ability by recording and maintaining a history of input and output conditions -
information that provides valuable insight into the operation of a process,
equipment, or facility. This information can be readily accessed through the RS-
232 port or via telephone.
Configuring the Data Logger

Whenever a system or log event occurs, the OMA-D560 system will write to memory a time-stamped record of
parameters. To check or modify the data logging control parameters, type LOG S.

Set/Check Log Time
When the data logger is configured for periodic logging, this parameter sets the data-logging interval. Valid
intervals range from 1 second to 120 minutes.
Periodic Log ON/OFF
When enabled, the OMA-D560 system will automatically log all input and output conditions at regular
intervals of time.
Alarm Log ON/OFF
When enabled, the OMA-D560 system will record all input and output conditions whenever an alarm event
occurs.
www.omega.com
18
Clear
This action permanently erases the contents of the data logger’s memory. Note: you normally do not have to
clear memory - when it is full, it will automatically clear the oldest information in its memory. You can use this
clear function after you download the contents of the data logger’s memory if you want to eliminate the
possibility of downloading redundant information in the future.
High Resolution Log
When the high-resolution log is enabled then two bytes will be stored for each input selected for logging.
When the high-resolution log is disabled, only one byte per selected input is logged.

OMEGA ENGINEERING, INC.
Compressed ASCII
A geek-readable text format in which all commas and other punctuation are striped out all, and data is presented
in hexadecimal notation. Downloads much faster than uncompressed ASCII.
Compressed XMODEM
The most reliable way to transfer large amounts of data from the OMA-D560 system to a personal computer is
with the XMODEM file transfer protocol. Many communications programs (such as Hyperterminal) support the
XMODEM protocol.
If a data error occurs during a file transfer (due to line noise, for example), XMODEM will detect the error and
attempt to correct it.
Once you initiate an XMODEM data transfer, you have 30 seconds to tell your communications program to
start the XMODEM transfer. Downloading a compressed log file is also possible. The data compression
scheme used in the OMA-D560 system strips out all commas and other punctuation, and converts the data from
ASCII decimal to binary. The result is a data file, which is at least one-fourth its original size and transfers in
one-fourth the time of the original data file. To decompress the data to its original comma-delimited form, use
the DOS decompression utility “D-COMP,” which is included on the companion disk. The program will
request the name of the input file and output file. When the conversion is complete, you will be able to view the
data with any text editor or load the data into a spreadsheet program such as Lotus 1-2-3 or Excel.

that can save you both time and money. An understanding of the commands
described in this section will help you maximize the return on your remote
monitoring investment.
The commands in this reference are listed in alphabetical order.
ALM (Alarm Commands)
These commands configure the OMA-D560 system to continually monitors all inputs for alarm conditions. If a setpoint has been exceeded for a designated period of response time, the OMA-D560 system recognizes this as the
existence of an alarm condition.

Open Communications Gateway
Type COM R at the command prompt and the OMA-D560 system will open a communications path between
the modem and its serial port. This path can be used to establish communications with a secondary OMA-D560
system or almost any other device that has an RS-232 port.
When using the communications gateway, make sure that the RS-232 cable connecting the OMA-D560 system
and secondary device supports full hardware (RTS/CTS) handshaking. If the secondary device does not
support hardware handshaking, you must make sure that neither device transmits more data than the receiver
can handle.
For example: If you have a OMA-D560 system operating its modem at 33.6 kbps and its RS-232 at 115 kbps
you must make sure that the device attached to the RS-232 port does not transmit data at a sustained rate of
115kbps. Because the OMA-D560 system would be receiving data 3.5 times faster than it can send it, the
receive buffer will fill up quickly. The OMA-D560 can buffer up to 256 incoming and outgoing bytes but any
data received after a buffer has filled up will be lost.
*Note: If you attach a device that continuously generates data to the OMA-D560 RS-232 port, you must enable
the smart gateway option. (See COM S).

CNT (Pulse Counter)
The OMA-D560 system allows pulse counting on all eight analog inputs. It uses two commands in data mode, CNT
R, to display all eight counters, and CNT O, to clear individual counters.
The maximum transition rate is 100 state transitions/second (50 Hz signal = 50 counts/second) with no two
transitions occurring within less than 10ms of each other. The signal can be a square, saw-tooth, or sine wave, with
a transition being a change from above three volts and below two volts, and vice versa. Total counts are displayed

Alarm Set-Points
Each of the input channels can be given alarm set points.
Inputs configured with a temperature, pulse rate, custom, linear, or 4 to 20 mA sensor type can be given
high and low alarm set points.
If the input value falls below the low alarm set point or above the high alarm set point for a defined period
of time, the OMA-D560 system will recognize an alarm condition. In the case of a dry contact, if the input
state equals the configured alarm state then an alarm condition is triggered.
To enter a low alarm or high alarm limit, type INP S. Each of the input items should be given a low set
point, below which the OMA-D560 system will be activated and send alarm messages, and a high set
point, conversely above which the system will be activated.
When adding data at the “Enter New Value” prompt, please note that the range depends on the input type
as well as the bottom and top of scale definitions.
To disable the low alarm, set it equal to the bottom of scale parameter. To disable the high alarm, set it
equal to the top of scale parameter.
Response Time
Each of the input channels can be given a response time. This time determines how long an alarm condition
must exist before it is recognized as an alarm. Type INP S and choose the input you want to modify from
the menu. A second menu will be given listing all parameters associated with that input. Choose Response
www.omega.com
28
Time and enter the desired response time. The response time can range from 1 second to 120 minutes. The
response time only applies to alarm set points.
Output ON / OFF Control Set-Points
Each of the input channels can be programmed with output control set points. The output control set points
only affect outputs that have a control mode of Automatic, Automatic Day, and Automatic Night. If the
input value goes above the output ON set point, the output will be turned ON and remain ON until it falls
below the output OFF set point. The response time does not apply to Output On and Output Off set points.
Calibration
Each of the input channels can be calibrated by adding (or subtracting) a calibration constant to the raw
(unscaled) input value. To enter a new calibration constant, type INP S and choose from the menu the
input you want to calibrate. A second menu will be given, listing all parameters associated with that input.
Choose "Calibration".
The OMA-D560 system will display the measured value of the input and ask you to enter the actual value.
When you do, a calibration offset will be calculated and stored in the OMA-D560 system's memory.
LOG (Event and Data Recorder)
It is often desirable to track conditions (such as tank level or ambient air temperature) over extended periods of

Security Codes
Your OMA-D560 system has three levels of security, each permitting access to the system but with varying
degrees of privilege. These security codes are also used when accessing the OMA-D560 system from a
touch-tone telephone.
Level Three security permits a user to access the report (“R”) commands.
Level Two security permits a user to access and change certain operational (“O”) commands as well as
report (“R”) commands.
Level One security permits a user to access and change the set-up commands (“S”) as well as the
operational (“O”) and reporting (“R”) commands.
To set or change security codes, you must have a level one Security Code. At the command prompt, type
SEC S and choose menu selections 1, 2, or 3.
You will be prompted to enter a new security code. The security code is eight digits long and all eight must
be entered. Only the digits 0-9 are accepted.
Entering your code number
You can program an eight-character alphanumeric code to provide your OMA-D560 system a unique
identity. That code, which will appear in the log-on message, typically is an account number, site code, or
serial number.
At the command prompt, type SEC S, choose menu selection number 4, and type your eight-character
code.
Entering the unit phone number
You can program a 15 character alphanumeric code to provide your OMA-D560 system with additional
identity. The unit phone number will be part of the OMA-D560 system’s voice mode alarm
dial message.
Entering your location name
Similarly, to complete your unique system signature, you can program your OMA-D560 system with a
location name which, like your code number, will appear in the log-on message. Typically, the location
name is the address where the system is located.
