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

1

2

3

Outputs

1 supervised input 1 supervised relay output (factory setting)

2 supervised inputs No relay output

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.

Model 7325-105 SmartSeries® Outdoor Metallic 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).

Model 7325-105 SmartSeries® Outdoor Metallic RTU Enclosure

Configuration 3

In the third configuration, the relay output circuit is nonsupervised. 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

TB3-24 Common

TB3-26 Common

TB3-27 Spare

TB3-28

TB3-29

Black (hot) 120 V ac 50/60 Hz, 3 amps max.

White (neutral) 120 V ac 50/60 Hz

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.

Pub. 42004-618L2B

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 7325-105 Outdoor Metallic RTU Enclosure is supplied with top and bottom openings for conduit. We highly recommend using only the bottom opening. This helps to prevent water from leaking in through the opening or trapped moisture from entering through the conduit. 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 0.437-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

Remove plastic plugs and install conduit to the enclosure. Feed the wiring through the conduit and bring it into the enclosure. Wire the station using Figure 7 as a guide. Follow the wire colors carefully because the colors noted in the figure correspond to GAI-Tronics 60029 Series multi-party cable. The wires must be spade-lugged and connected securely 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.

The following steps will mutually mute the 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.
