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

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.

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 7.
CAUTION
For safe operation, connect terminal 3 of TB1 to system ground.
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.
The following steps mut u ally mutes adjacent amplifiers/ha ndsets within a zone.
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.
Alternate Page Destination
Alternate page destinations must be s of tware configured in the central control cabinet of a GAI-Tronics
ADVANC E system. Refer to F i gure 7 f or the connection point s located on TB3.

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.-lb s. M ake cert ain no cover bolts are omitt ed. Use only thos e b olts supplied with
the enclos ure.

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.
