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.

Inputs should be wired with 14 to 20 gauge wire. Twisted pair cable is recommended for runs in excess of 20
feet. Input devices requiring 12 VDC can be powered from the OMA-D560’s 12 VDC auxiliary output
terminal.
When wiring the inputs, keep in mind that they share a common ground and that the input signals must not
exceed 5 VDC or 25 mA.

Connecting the Outputs
The OMA-D560 has four outputs that can be controlled remotely or automatically in response to alarm conditions
or input parameters. The control capabilities of these outputs are described in the “Control” section of this manual.
Output Relays
Each of the four outputs is capable of switching 5 amp loads. Note: When switching voltages in excess of 30
volts, the OMA-D560 must be placed in an approved enclosure.
Switched AC Outlet
You can also plug equipment (seven amp maximum load) into the “Switched AC” power outlet located on the
side of the unit (110 VAC units only). This switched outlet works in unison with the output 1 relay on the front
panel.

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
