equipment.

CAUTION

hazardous areas other than those indicated on the approval
listing in the Specifications section of this manual. Such
installation may cause a safety hazard and consequent injury
or property damage.

WARNING

Do not mount the enclosu re with hinges on the top or bottom side.

Securely fasten the enclosure to the mounting location, using 1/ 2-inch dia meter steel mount ing bolts and
washers, or washer head bolts.

WARNING

Do not disconnect equipment while energized.

Insure proper grounding to protective earthing.

Inspect and c lean the machined flange fla me joint sur f aces of both the cover and b ox. Surfaces must be
smooth, f ree of nicks, scrat c hes , dirt or any foreign p article build-up that wou ld prevent a pr oper seal.
Surfa c es must seat fully aga inst ea c h other to provide a prop er explos ion- proof joint. C l ean surfaces by
wiping with a clean lint-free cloth.

Apply a light coat of Killa rk “LUBG” lub rica nt to flange surfac es and close t he cover. Ins tall and tight en
all cover bolts to 30 f t-lbs . Ma ke c erta in no c over bolts are omitted. Us e only those bolts supplied with t he
enclosure.

When installing an add-on st ation, consu lt the appr opriate sys tem layout diagrams. 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.

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 rec ommended. For the numb er, s iz e, and color-coding of c onductors refer to the approp riate system
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 120 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.

The sp eaker a mplif ier enclosure contains two terminal b loc ks, an interior mounting p late, an amplifier
bridging plat e, and a connector for the mating Model 709-901 Amplifier. The amplifier bridging plate is
hinged on one side and attached on the opposite side with two #10-32 screws. For system cable
installation, t he s c rews t o this plate mus t be removed and the bridging plat e s wung open 90º. Upon
installat ion of the wiring c able, the amplifier bridging pl ate can be rotated cl osed and reatt ached with the
two #10-32 screws. This plate will then serve as a pr otection for the amplifier and t he s wit c hes f rom the
system cabl e wh en the u nit is comp l etely closed. Refer to F i g ure 3.

Mounting

NOTE: The mounting surface must be able to support the weight of the aluminum enclosure. See the
Specif ic ation s ection for the weight and dimensions of the unit.

The enclosure comes s tandard with mounting feet c apable of being rota ted 90º . This allows f or top and
bottom mounting feet or side-to-side mounting f eet . The enclosure ships wit h the mounting feet in the top­to-bottom configu ration, for ease of insta llation. Refer to Figu re 4 for both sets of dimensions .

Figure 4. Model 707-001-EX-F07045 Enclosure Mounting Details

The en clos ure must be s ecurely fastened with 1/2-inch d i ameter s teel moun ting bolt s loc ated o n all four
mounting feet. St ainless steel hardware is r ecommended in outdoor ap plications.

Wiring

Attach the conduit or c able gla nds to the enclosur e. Feed the wir ing throu gh these and b ring it int o the
enclosure. Attach the wires to the ter mina l blocks located behind t he amplifier b ridging plate. Follow the
wire color s carefully b ecause the colors c orres pond to GAI- Tr onic s cab l e. The wir es must be s pade-lu gged
and connect ed carefully and complet ely to the ter mina l block. An improper termination may res ult in
diminished station performance. S ee F igure 6.

CAUTION

For safe operation, connect terminal 3 of TB1 to system ground.

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.

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 p ecific need for preventive maintena nc e.

®

In addition, t he following procedu re 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.

CAUTION

To reduce the risk of ignition of hazardous atmospheres, disconnect the equipment from the supply
circuit before making any adjustments to the amplifier's handset level.

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 .

Inspect and c lean the machined flange fla me joint sur f aces of both the cover and b ox. Surfaces must be
smooth, f ree of nicks, scrat c hes , dirt or any foreign p article build-up that wou ld prevent a pr oper seal.
Surfa c es must seat fully aga inst ea c h other to provide a prop er explos ion- proof joint. C l ean surfaces by
wiping with a clean lint-free cloth.

Apply a light coat of Killa rk “LUBG” lub rica nt to flange surfac es and close t he cover. Ins tall and tight en
all cover bolts to 30 f t-lbs . Ma ke c erta in no c over bolts are omitted. Us e only those bolts supplied with t he
enclosure.

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.

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 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 coverage can be
adver sely aff ected.

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.
