General Information

The Model 703-004 Indoor Emergency Pa rty L i ne Amplifier Enclosure is designed to be a c omponent in a
GAI-Tronics SmartSeries system. It is a multi-party, 115 V amplifier enclosure that mates with a Model
701-80x or 701-90x Series Handset/Speaker Amplifier to form a SmartSeries station.

When connected to a SmartSeries s ystem, the s tation is equipped to rep ort t he following information when
the handset is t aken off-hook:

• Zone number

• Station address

• Pa rty line (1 or 2)

All station r ep orts are received by the Master Control Unit and annu nc iated on a n access panel located in
the SmartSeries

N

OTES:

1. The Model 703-004 Enclosure can also mate with a standard 701 or 751 Series Amplifier; however,

the reporting feature is not op erab le wit h this combination.

2. EPL f unctionality is only possible if your system’s software is prop erly configured. Your sys tem must

als o have the address of the station int ended t o ma te with the enclosure enabled. Should you have
quest ions rega rding your system, plea se conta c t your nearest GAI-Tronics Service Center.

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, consult the sys tem layout diagrams at the end of this ma nual. These
figures, when used in conjunct ion with the st ation ins tallation information and cable layout guide, should
provide all the infor ma tion necessary to insta ll additional Pa ge/ Party< stations.

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 acc ompanying sys tem
connection diagra ms .

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 703-104 Indoor EPL Amplifier Enclos ure is not sup plied with openings f or conduit or cable
becau se the pla c ement will vary ac c ording to the application. Drill or punc h these openings us ing the
template supplied before mount i ng the enclosure. We highly rec ommend using only t he b ottom entr y to
prevent mois tur e from dripping onto the terminals or PCBAs. The best loc ation f or conduit holes is a l ong
the bottom of the encl o sure near the r ear su rface. If the top opening i s to be used, carefully seal ar o und t h e
fitting to prevent moisture from entering.

For specific details including mounting hole dimensions, refer t o Figur e 1 . There ar e fou r 5/ 16-inch
diameter mounting holes in the corners of the amplifier enclosure. The suggested mounting height for a ll
station enclosures is 54 inches (137 cm) to the centerline of the enclosure.

OTE: Labels denoting whic h party line(s) is configured as the emergency party line are included in a n

N

envelope inside the enclosu re. The labels ar e f or Part y Line 1, Party Line 2 , and Party Lines 1 and 2
configurat ions. Ap ply the appr op ria te label ins ide you r enclosu re.

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 2. Follow the wire colors caref u lly becau se the colors noted in the figure correspond to GAI­Tronics 60029 Series multi-party cable. The wires must be spade-lugged and connected securely to the
termina l block. An improper termination can result in diminis hed s tat ion performance.

Local Muting

Figure 2 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.

The following steps will mutu ally mute the adjacent amplifiers /hands et s 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.

Maintenance

Regula r insp ection and a good pr eventive maintenance program will increase the relia bility of you r
GAI-Tronics station. The GAI-Tronic s Field Service Depa rtment can formulate a service cont rac t suited
to your fac ility’s s pecific need for preventive maintenance. I n addition, the following procedur e can be
used to keep Page/Party

®

systems o perat i n g effectively .

WARNING

Before performing any of the following preventive maintenance steps, remove

all power from the station.

1. Remove the a mplifier f rom the enclo sure.

2. Visually check the int erior of the enclosure for signs of c ontamination suc h as du st, c ondens ation or

process liquid.

3. Using the No. 10440-002 Maintenance Cable, plug the amplifier into the connector in the enclosur e.

Check, and if necessary, adju st the amplifier t o ma x i mize performa nc e.

4. Reinstall the amplif ier in the enclosure. Ensure t hat a ll gaskets and hardwar e are in place. F ailur e t o

install the gaskets, which als o act as s pacer s, can result in da ma ge to the connectors on t he amplifiers
and insi de t he enclosur es and ca n c aus e s ystem faults .

It may become necessary to re-terminate some or all of the enclosures in a system. If so, strip the wires
bac k to clean c opper and connect only one wire to eac h c onnector to allow for eas i er fut ure
troubleshooting.

If the equip ment requires service, c ontact your Regional Service Center for a return authorization number
(RA# ) . Equi p ment should be s hipped prepaid to GAI-Tronic s with the return au thoriz ation numb er and a
purchas e order numb er. If the equipment is u nder war ranty, repairs will be made wit hout charge. Please
include a written explanation of all defects to as sist ou r technic ians in t heir tr oubleshoot ing ef f orts . Call
800-492-1212 for help in identifying the Regional Service Center closest to you.

Troubleshooting

The following t able lists some hints to aid technicians in trou bleshooting.

Problem Solution

Feedback
occurs only
duri ng page.

Crosstalk
occurs.

1. If a speaker is clos e t o the station, try u sing the muting f eature in the amplifier

enclosure at the termina l blocks. Connect the violet wire a t TB 1-8 t o TB1- 7 . Refer
to the wiring diagram.

2. Ensu re tha t speakers att ached to other stat ions located nearby are not point ed in you r

direct ion. If changing the or ient ation of the other s peakers has no ef f ect, mutual
muting may b e required. Mutual mut ing silences all the speakers within proximit y to
the af f ected stations during a pa ge from any one of t he mutually mu ted stations.
Connect the ora nge wire (spare) to the T B1-7 of all the stat ions to be mut ually
muted. N ote: If too ma ny sta tions a re selected, paging c overage can be adversely
affected.

3. Check line ter mina tions a t the line balance assembly. Li ne b alance assembly

connections are critical.

One or mor e system cable pai rs may b e i mproper l y ter min ated . Visually in spec t th e
system cable connections for acc idental cross i ng of the cab le p airs or grounds.
