General Information

The Model 7335-004 Outdoor Non-metallic E mer gency Party Line Amplifier Enclos ure is des igned t o be a
component 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 SmartS eries sys tem, this sta tion is equip ped to rep ort t he following inf ormation 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 control cabinet.

OTES:

1. The Model 7335-004 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. E mer gency party line func tionalit y is only possible if your sys tem’s software is properly configured.
Your system must also have the address of the s tat ion intended to mat e wit h the enclosure enabled. Should
you have qu es tions a s to the capabilities of your s ystem, please contact your nea rest G AI - Tr onic s Servic e

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 one mile (5280 feet) for 115 V ac systems. The total cable length is the most important
consideration while cable length between the sta tions is generally not a fa c tor.

Mounting

The Model 7335-004 Outdoor Non-metallic E PL Amplifier Enclosure is not supp lied wit h openings for
conduit or cable becau se the pla c ement will vary acc ording to t he a pplica tion. Drill or punch thes e
openings us ing the template supplied before mounting the enclosure. We highly recommend using only the
bott om entry to p revent moisture from dripp ing onto the terminals or PC B As. The best loc ation for conduit
holes is a long the bottom of the enclosure near the rear su rfa c e. If the top opening is to be used, c arefully
seal around the fitting to prevent moisture from entering.

For specific details including mounting hole dimensions, refer t o Figur e 1 . There ar e fou r 7/ 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 wir e colors carefully beca use the colors correspond to GAI- Tronic s 60029 Series
multi-p arty cab l e. The wir es mu st be s pade-lugged and connected s ecurely to the termina l block. An
improper termination ca n result in diminished station performa nc e.

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.

Troubleshooti ng

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

your direction. If changing the or ient ation of the other s peakers has no ef f ect,
mutual muting may be required. Mu tual muting silences all the sp eakers within
proximity to t he affected s tations during a p age from any one of the mutually
muted st ations . Connect the orange wire (s pare) to the TB1-7 of all the stations to
be mutually mut e d . N

OTE: If too many stat ions are selected, paging coverage 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.
