General Information

The Model MS05-101 Desktop Master Station is designed to operate with the GAI-Tronics MI05-10x
Series Merge/Isolat e Cabinets in a multi-zone Page/P arty

®

communicat ion syst em.

The Model MS05-101 Desktop Master Station can selectively merge and isolate up to five zones that
normally op erate independently. When merged, the zones share a page line and a party line. F or exa mple,
two zones can be merged while the r ema ining z ones are is olated a nd c ontinue to op erate independently.
Voice pages generated from handset s tations within one zone c an be heard in another zone when the two
zones are merged. The Model MS05-101 Master Station controls the actual merging and isolating of the
zones.

Additiona l f eatures a re availab le depending on model of the merge/ isolat e cabinet and the system’s
accessories. Refer to GAI-Tronics publications for the Model MI05-101, MI05-103, and MI05-104
Merge/I solat e C abinets for system and ma ster sta tion capabilities. These include:

• Initia ting voice pa ges to selective zones

• Conduc ting two-way conversat ions with handset s tations

• Monitoring voice pages fr om selective zones

• Merging p age and p arty line channels

• Receiving visual a nd audible call-in signals from handset sta tions

• Activating and res etting a l arm t ones

The MS05-101 Master Station consists of the following components:

• MS05-101S Desktop Subset

• MS05-101A Remote Handset/Speaker Amplifier

• MS05-101E Amplifier Enclosure

Installation

Mounting and Wiring T erminations

1. Drill or punc h the conduit or cable openings prior t o mounting the amplif ier enclosure. All entr ies to

the amplif ier enclosure should be made from the b ottom or s ides.

OTE: Use caution when drilling holes to avoid damage t o interna l electrical components and wiring.

N

2. Surfa c e mount the amplifier enclosure using the four mounting holes loca ted on the rear of the

enclosure. The amplifier enclosur e can be mounted at a remote location, not to exceed the length of the
15-foot subset cable.

3. Connect all part y lines and the page line wiring t o TB1 and TB2 i n the enc l o sure.

Refer to the Wiring Terminations Table.

4. Connect the RS - 485 data line wiring to TB3 the encl osure.

Refer to the Wiring Terminations Table.

5. If a n ex terna l speaker is used, connect the sp eaker wires to TB1.

• 8-ohm speaker: TB1-4 and TB1-5

• 16-ohm speaker: TB1-4 and TB1-6

6. Plug the 15-f oot ca b l e connector f rom the subset to the socket on the front of the amplifier enclosur e.

7. Connect 120 V ac power conductors t o TB1-1 (H), TB1-2 (N), and TB1-3 (GND) of the amplifier

enclosure.

8. Plug th e ampl i fier int o the enc l o sure a n d tighten t he screw in each c o rner of the a mplif i er.

9. Apply power.

Setting the Station’s Address

4 of 11

Eac h ma ster sta tion in the sys tem requir es a uniqu e address. If two mas ter stations have the same address,
data collision will occ ur when communicating with the merge/isolat e cabinet, resulting in a f ault c ondition.
The master station addresses must be set in sequence starting at 1. Do not skip any numbers when
assigning addresses .

The I/ O control board is located ins ide t he desktop subset . This determines t he s tation address and als o
controls the s tat ion’ s zone and alarm selection fea tur es by scanning the switches a nd then transmitting the
selection to the merge/isolate ca b i net over a data line. There are sever al switc hes and jumper s on the I/O
board that must be set correctly for the station to operate correctly. Refer to Figure 1 below for I/O
contr oller boa rd out line and switc h locations.

Figure 1. I /O Controller B oard

Switches S1 and S2

S1 and S2 are hexadecimal s witches that are used to set the I/O board’s address. If the sys tem contains
more tha n one ma ster station, each st ation’ s I/O board must be set wit h a different sequential addres s
starting with 01 . Swit c h S2 sets the first digit and switch S1 sets the second digit.
