Application
The SmartSeries® Station RTU is designed to be used with the SmartSeries® amplifiers and handsets in a
standard multi-party Page/Party® system. It is also possible to control an external device by activating 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
1 supervised input
1 supervised relay output (factory setting)
2
2 supervised inputs
No relay output
3
2 supervised inputs
1 non-supervised relay output
Configuration 1
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.
NOTE: This configuration is hardwired at the factory.

Model 703-005 SmartSeries Indoor RTU Enclosure
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.
NOTE: 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:

Earth ground
The SmartSeries® RTU is pre-wired from the factory to support 1 supervised input and 1 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
Do not install this equipment in hazardous areas or areas other than those
indicated on the approval listing in the Specification section of this manual. Such installation may
cause a safety hazard and consequent injury or property damage.
When installing an add-on station, consult the system connection diagram, Figure 7. These figures, when
used in conjunction with the station installation information and cable layout guide, should provide all the
information necessary to install additional Page/Party< stations.
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 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 1 mile (5280 feet) for 115 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 703-005 Indoor RTU Enclosure is not supplied with openings for conduit or cable because their
locations vary with each installation. Drill or punch these openings using the template supplied 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 best location for conduit holes is along the bottom of the
enclosure near the rear surface. Avoid the top center, as it may interfere with the plug-in amplifier
receptacle. If the top opening must be used, carefully seal around the fitting to prevent moisture from
entering.
For specific mounting details, refer to Figure 6. 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.

Wiring
Attach the conduit to the enclosure. Feed the wiring through the conduit and bring it into the enclosure.
See Figure 7. Follow the wire colors carefully because the colors correspond to GAI-Tronics 60029 Series
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.
Local Muting
Figure 7 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.
Use 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
include a written explanation of all defects to assist our technicians in their troubleshooting efforts. Call
800-492-1212 for help in identifying the Regional Service Center closest to you.

Problem
Solution
Station responds to polling
messages but the relay output
does not respond.
Check for trouble report from station if the output is being supervised.
The report will indicate what type of trouble has occurred. If the
message, “Supervised Output Circuit” is reported, check relay circuit
and supervision path.
Station does not respond to poll
message.
Check and replace fuse on the back panel of the enclosure as well as
fuses on the SmartSeries® device.
The following device fault
message received at the MCU:
“Supervised Input Circuit”
Check that the input circuit is properly terminated.
Check the external circuit connected to either input of the RTU for a
short or open. The input circuit number is identified on the device fault
message.
Device fault message is not
received but the input circuits
do not activate an alarm.
Verify that the SST configuration is set up to report the alarm.
A device fault is not reported to
the MCU but the output circuit
does not respond to an
activation command.
Check and replace the SmartSeries® station relay circuit card.
