station enclosure. This circuit is referred to
as a relay output. Terminal bloc k TB3, located on the rea r panel of the stat ion enclosur e, provides an
interface with this relay.

In addit i on to the relay outp ut capability, the RT U also provides two inp uts. Thes e circuits provide an
interface to dry contact switches, (e.g., a pull box) that are monitored within the SmartSeries

Hardware Configuration

The Sma rt Ser i es® RT U allows t hree choices of opera tional conf igurations. Select the configuration tha t
best suits your need for circ uits. The following tab le lis ts the RTU conf igurations:

Configuration Inputs Outputs

1
2
3

Configuration 1

1 supervised input 1 supervised relay output (factory setting)
2 supervised inputs No relay output
2 su p ervised inputs 1 non-super vised relay ou tput

In the first c onf igura tion, t he relay output is sup ervised to continually ens ure the int egrity 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 2 0 k-ohm, 2- watt resis tor p laced in para llel to the relay outp ut device (e. g. a b eacon or
strobe) as shown in Figure 2.

Figure 2. B eacon or Strobe

Wire t he t erminating resistor as close as p ossible to the bea c on. Su pervision is perf ormed during non­act i vation of the relay outpu t using I N 1. The second input, I N 2, remains a vailab le f or 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.

OTE: This configu ration is ha rdwired at the factory.

Configuration 2

The second c onf iguration uses two supervised input
circ uits and does not make use of t he s i ngle relay
outp ut. This conf iguration is accomplished b y
interfacing to terminal block TB3-23 and TB3-24 for IN
1 and TB3-25 and TB3-26 for IN 2.

The ext ernal dry contact s witch, eit her norma lly open or
normally cl osed respectively, shou ld be in parallel to a
15 k-ohm resistor as shown in F igure 3.

A 5.1 k-ohm resistor should be in series to the 15
K-ohm resi stor . This pr ovides a voltage divider networ k
used to detect a short or open across the external
circuit’s ca b ling.

This c onf iguration r equ ires that t he orange wir e from
TB3 - 23 going to the relay output circuit be disconnect ed
so as no t to i n ter fere wi th supervised opera tion.

Another method of performing sup ervision using
multiple swit c hes is shown in Figure 4. This method
requires only one 20 k- ohm resist or that is placed in
parallel to multiple norma lly 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 act i vate or deactivate without t he
integrity of the ext ernal circuit being verified. In this
configuration, both inputs are available.

Software Configuration

The sof tware configuration of the RTU is accomplis hed through the use of the System Sta rt- u p Tool
(SST) . The t ype of RTU is dependent on the hardware configurat ion. Befor e s etting up the sof tware, it is
important t o know how t he inp uts and outputs will be used.

Interface

Use the ribbon c onnec tor s upplied wit h the unit to c onnect the SmartSeries® relay c i rcuit to the connec tor at
the base of the SmartSeries
the ap prop riate lugs on t he TB3 t erminal bloc k loc ated on t he rear panel on the enclos ure. The following

The Sma rt Ser i es® RTU is pre-wired from the factory to support 1 supervised input and 1 supervised relay
outp ut. To disable the supervision of the r elay output c ircuit by IN 1, disc onnect the or ange wire going to
the relay circ uit card located a t TB3 -23. This is the only wiring modific ation neces sary for any of the t hree
RT U configurat ions.

Operation

The supervised input and relay output functions are supported by the ADVANCE system.

Installation

CAUTION

indicated on the approval list ing in the Sp ec ification section of this manual. Such installation may
cause a safety hazard and consequent injury or property damage.

When installing an add-on st ation, consu lt the system connection diagram, Figu re 7. These figu res, when
used in conju nction with t he s tat ion insta llation information and ca b l e layout gu ide, should p rovide all t he
information necessary t o insta ll additional Pa ge/ Party< stat ions.

Do not install this equipment in hazardous areas or areas other than those

Enclos ure Placement

All GAI-Tronics Pa ge/ Party® units are wired in parallel. G ood system layout design minimizes the cable
required for ea ch insta llation. GAI-Tronics multi-condu c tor cable, des igned especially for this applic ation,
is recommended. The number, size, and color-coding of condu c tors are lis ted in the system connection
diagram.

System layout and power c able length are ver y important when inst alling Page/Party< equipment.
Although it vari es f or differ ent systems, the general guideline is t hat t he t otal p ower 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 lengt h b etween the sta tions is generally not a fa c tor.

Mounting

The Model 703-005 Indoor RTU E nc l osur e is not supplied with openings for condu it or cable because their
locat ions vary with each insta llation. Drill or punc h these openings using the templa te supplied before
mounting the enclo sure.

Whenever po ssi ble, d o n ot ent er an enclo sure from t he top : side or bo tto m entr y h el ps to prevent moisture
from dr ipping onto the termina ls or PCBAs. The b es t location for c onduit holes is along the bottom of the
enclosure nea r t h e rea r s urface. Avo i d the to p center, a s it may interfere wi th t h e 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
corner s of the a mplif ier enclosure. The suggest ed mount i ng height f or all station enclosures is 54 inches
(137 cm) up to the centerline of the enclosure.

Wiring

Attach the conduit to the enclosure. F eed the wiring through the condu it and b ring it into the enclosu re.
See Figu re 7. Follow the wir e colors carefully beca use the colors correspond to GAI- Tronic s 60029 Series
multi-party cable. T he wires must be spa de-lugged and connect ed carefully and completely to the ter mina l
block. An improper termination may res ult in diminished stat ion performance.

Local Muting

Figure 7 illus trates local speaker muti ng when stat ions are completely assembled and paging operation
occurs. N ormally, when t he s tation but ton is pressed, the paging spea ker connected t o that sta tion is
silenced (muted) to pr event acoustic feedback to the handset microphone. H owever, while the handset is in
use for party line conversations, the paging speaker is “live” t o enable pa ging c alls from other s tat ions.

To d i sa ble th e mute f eatur e, fol l o w thes e i n struction s:

1. Locate the lugged violet wire attached to terminal point 7 (Mute) on the terminal block within the

enclosure.

2. Transf er the lugged violet wire to terminal point 8 (Page L1).
After any muting changes a re made, u npack the sta tion amplif ier and ins tall.

Mutual Muting

In the event that f eedback occu rs within an a rea and repositioning of the system speaker s does not help,
mutual muting may be used to correct this problem.

Use the following st ep s to mutu ally mute a djacent a mplifiers/ handsets within a z one.

1. Ensure that the p u rple lugged wire is connect ed t o terminal 7 of TB 1 .

2. Connect terminal TB1- 7 of the ha ndset stat ion to TB1 -7 of t he s tat ion within the zone that is c ausing

feedback. This is done by u sing the sp are s ystem wire (orange conduc tor) f rom within the s ystem
ca ble t h at ru n s between th e stat i o n s.
