General Information
The Model 703-007 RTU (Remote Terminal Unit) Enclosure is designed to be a component in
GAI-Tronics SmartSeries system. It mates with a SmartSeries handset or speaker amplifier to form a
SmartSeries station.
®
When connected to a SmartSeries system, the station operates as a standard multi-party Page/Party
device. In addition, it supports supervised input circuits and a relay output (supervision optional). The
following configurations are possible:
• One supervised input circuit and one supervised relay output (factory setting)
• Two supervised input circuits and no relay output
• Two supervised input circuits and one non-supervised relay output
OTE: The relay output circuit is intended for use with GAI-Tronics-approved equipment. The circuit
N
may not support supervision of equipment that is not approved by GAI-Tronics.
How to Use the Assembly/Model
This section describes applications for the Model 703-007 SmartSeries RTU Enclosure, its hardware,
software configuration, interfaces and operation.
Application
The SmartSeries Station RTU is designed for use with the SmartSeries amplifiers and handsets in a
standard multi-party Page/Party
and deactivating a single relay circuit located in the SmartSeries station enclosure. This circuit is
referred to as a relay output. Terminal block TB3, located on the rear panel of the station enclosure,
provides an interface with this relay.

In addition to the relay output capability, the RTU also provides two inputs. These circuits provide an
interface to dry contact switches, (e.g., a pull box) that are monitored within the SmartSeries station. The
SmartSeries station reports any switch activation to the Master Control Unit (MCU).
The relay output is factory-set to be supervised through input #1. Refer to Figure 1. However, you may
elect to use input #1 by disconnecting supervision for the relay output.

Hardware Configuration
The SmartSeries RTU allows three choices of operational configurations. Select the configuration that
best suits your need for circuits. The following table lists the RTU configurations:
Configuration Inputs Outputs
1
2
3
Configuration 1
One supervised input One supervised relay output (factory setting)
Two supervised inputs No relay output
Two supervised inputs One non-supervised relay output
In the first configuration, the relay output is supervised to continually ensure the integrity of the external
circuit. The first input, IN 1, is used to support supervision of the relay output circuit. This wiring
method requires the use of a 20 k-ohm, 2-watt resistor placed in parallel to the relay output device (e.g. a
beacon or strobe) as shown in Figure 2.
Figure 2. Beacon or Strobe
Wire the terminating resistor as close as possible to the beacon. Supervision is performed during nonactivation of the relay output using IN 1. The second input, IN 2, remains available for detecting switch
activations. The following section describes switch wiring choices. The RTU provides 120 V ac for
beacon power on pins TB3-28, TB3-29, and TB3-30.

Model 703-007 SmartSeries RTU Enclosure Page 4 of 12
Configuration 2
The second configuration uses two supervised input
circuits and does not make use of the single relay
output. This configuration is accomplished by
interfacing to terminal block TB3-23 and TB3-24 for
IN 1 and TB3-25 and TB3-26 for IN 2.
The external dry contact switch, either normally open
or normally closed respectively, should be in parallel to
a 15 k-ohm resistor as shown in Figure 3.
A 5.1 k-ohm resistor should be in series to the 15
K-ohm resistor. This provides a voltage divider
network used to detect a short or open across the
external circuit’s cabling.
This configuration requires that the orange wire from
TB3-23 going to the relay output circuit be
disconnected so as not to interfere with supervised
operation.
Another method of performing supervision using
multiple switches is shown in Figure 4. This method
requires only one 20 k-ohm resistor that is placed in
parallel to multiple normally open dry contact switches
at the end of line (EOL).

Configuration 3
In the third configuration, the relay output circuit is
non-supervised. This means the RTU can command
a system device to activate or deactivate without the
integrity of the external circuit being verified. In
this configuration, both inputs are available.
N
OTE: Unused inputs must be terminated at
terminal block TB3 with a 20 k-ohm, 2-watt resistor.
Resistors are supplied with the units. See Figure 5.
Figure 5. Unused Input
Software Configuration
The software configuration of the RTU is accomplished through the use of the System Start-up Tool
(SST). The type of RTU is dependent on the hardware configuration. Before setting up the software, it
is important to know how the inputs and outputs will be used.
Interface
Use the ribbon connector supplied with the unit to connect the SmartSeries relay circuit to the connector
at the base of the SmartSeries station. Wiring to the RTU is performed by connecting the external
circuits to the appropriate lugs on the TB3 terminal block located on the rear panel on the enclosure. The
following table shows the wiring for TB3:
Terminal Block
Lug No.
Label
TB3-23 IN 1
TB3-24 Common
TB3-25 IN 2
TB3-26 Common
TB3-27 Spare
TB3-28 Line (hot) 120 V ac 50/60 Hz, 2.5 amps max.
TB3-29 Neutral 120 V ac 50/60 Hz
TB3-30 Earth ground
The SmartSeries RTU is pre-wired from the factory to support one supervised input and one supervised
relay output. To disable the supervision of the relay output circuit by IN 1, disconnect the orange wire
going to the relay circuit card located at TB3-23. This is the only wiring modification necessary for any
of the three RTU configurations.
Operation
The supervised input and relay output functions are supported by the ADVANCE system.

Installation
CAUTION
indicated on the approval listing in the “Specifications” section of this manual. Such installation
may cause a safety hazard and consequent injury or property damage.
WARNING
Do not disconnect equipment while energized.
Insure proper grounding to protective earthing.
When installing an add-on station, consult the appropriate system connection diagram. When used in
conjunction with the station installation information and cable layout guide, it should provide all the
information necessary to install additional Page/Party< stations.
Do not install this equipment in hazardous areas or areas other than those
Enclosure Placement
All GAI-Tronics Page/Party® units are wired in parallel. Good system layout design minimizes the cable
required for each installation. GAI-Tronics multi-conductor cable, designed especially for this
application, is recommended. The number, size, and color-coding of conductors are listed in the
appropriate system connection diagram.
System layout and power cable length are very important when installing Page/Party< equipment.
Although it varies for different systems, the general guideline is that the total power cable length should
not exceed one mile (5280 feet) for 120 V ac systems. The total cable length is the most important
consideration while cable length between the stations is generally not a factor.
Mounting
The Model 703-007 RTU Enclosure is not supplied with conduit or cable openings. Drill or punch these
openings using Figure 6 before mounting the enclosure. Whenever possible, do not enter an enclosure
from the top: side or bottom entry helps to prevent moisture from dripping onto the terminals or PCBAs.
The entry holes should be placed on the enclosure per Figure 6.
Plain entry holes must maintain the following:
• The plain hole shall be no larger than 0.7 mm above the major diameter of the entry thread.
• The gland or stopping plug is secured internally by a locknut, such that the gland or stopping plug
will be not dislodged by a 7 N-m impact.
• The enclosure will be maintained at IP 66 by a suitable sealing washer under the shoulder of the
cable gland or conduit hub.
The customer may drill plain entry holes in the enclosure providing they are in accordance with the
relevant code of practice and comply with the details shown in Figure 6. When mixed entries are
accommodated on a face they must be in the positions shown in this manual for the largest gland entry on
that face. For complex mixed entries, contact GAI-Tronics Technical Sales. Entries into the enclosure
must be via a suitable approved entry device. All unused entry holes must be fitted with a stopping plug
with a certification equal to that of the enclosure’s ATEX certification. The stopping plug shall be held
in place by a locknut.

For specific mounting details, refer to Figure 7. There are four 0.312-inch diameter mounting holes in
the corners of the amplifier enclosure. The suggested mounting height for all station enclosures is 54
inches (137 cm) up to the centerline of the enclosure.
For continued IP 66 protection, torque setting for securing the amplifier to the enclosure should be 10 to
12 in-lbs. or 1.13 to 1.36 N-m.

Wiring
Refer to the appropriate system layout diagram. Follow the wire colors carefully because the colors
correspond to GAI-Tronics multi-party cable. The wires must be spade-lugged and connected carefully
and completely to the terminal block. An improper termination may result in diminished station
performance.
CAUTION
For safe operation, connect terminal 3 of TB1 to system ground. See Figure 1.
Local Muting
The appropriate system layout diagram illustrates local speaker muting when stations are completely
assembled and paging operation occurs. Normally, when the station button is pressed, the paging speaker
connected to that station is silenced (muted) to prevent acoustic feedback to the handset microphone.
However, while the handset is in use for party line conversations, the paging speaker is “live” to enable
paging calls from other stations.
To disable the mute feature, follow these instructions:
1. Locate the lugged violet wire attached to terminal point 7 (Mute) on the terminal block within the
enclosure.
2. Transfer the lugged violet wire to terminal point 8 (Page L1).
After any muting changes are made, unpack the station amplifier and install.
Mutual Muting
In the event that feedback occurs within an area and repositioning of the system speakers does not help,
mutual muting may be used to correct this problem.
Perform the following steps to mutually mute adjacent amplifiers/handsets within a zone.
1. Ensure that the purple lugged wire is connected to terminal 7 of TB1.
2. Connect terminal TB1-7 of the handset station to TB1-7 of the station within the zone that is causing
feedback. This is done by using the spare system wire (orange conductor) from within the system
cable that runs between the stations.

Maintenance
Regular inspection and a good preventive maintenance program will increase the reliability of your
GAI-Tronics station. The GAI-Tronics Field Service Department can formulate a service contract suited
to your facility’s specific need for preventive maintenance.
®
In addition, the following procedure can be used to keep Page/Party
systems operating effectively.
WARNING
Before performing any of the following preventive maintenance steps,
remove all power from the station.
1. Remove the amplifier from the enclosure.
2. Visually check the interior of the enclosure for signs of contamination such as dust, condensation or
process liquid.
3. Using the No. 10440-002 Maintenance Cable, plug the amplifier into the connector in the enclosure.
Check, and if necessary, adjust the amplifier to maximize performance.
4. Reinstall the amplifier in the enclosure. Ensure that all gaskets and hardware are in place. Failure to
install the gaskets, which also act as spacers, can result in damage to the connectors on the amplifiers
and inside the enclosures and can cause system faults.
It may become necessary to re-terminate some or all of the enclosures in a system. If so, strip the wires
back to clean copper and connect only one wire to each connector to allow for easier future
troubleshooting.
To maintain system operations, we recommend keeping one SmartSeries RTU per every ten installed
units in the site maintenance inventory.
If the equipment requires service, contact your Regional Service Center for a return authorization number
(RA#). Equipment should be shipped prepaid to GAI-Tronics with the return authorization number and a
purchase order number. If the equipment is under warranty, repairs will be made without charge. Please
