INSTALLATION MANUAL
FLUSH-MOUNT HANDS-FREE
MASTER STATION
N-8031MS
Thank you for purchasing TOA's Flush-Mount Master Station.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. GENERAL DESCRIPTION
2.2. On-Wall Mounting Using a Wall-Mount box
The N-8031MS is a flush- or surface-mount master station
designed to operate in conjunction with TOA IP Intercom
Exchange and features high quality hands-free
conversation.
Connecting a foot switch or other external switch to the
external dial input terminal permits one-touch dialing
operation by way of such switches.
Handset conversation can be made in conjunction with the
optional RS-191.
Attach the N-8031MS to the YC-251 Wall-Mount Box
installed on a wall.

Though the socket on the PC board is faced inside, you
can insert the handset jumper into the socket from the
side.
Step 2. Install the ferrite clamp (supplied with the N8031MS) onto the RS-191's handset cables.
Then, connect the cables to the N-8031MS's
handset connection terminal.

3.3. Connection to External Switch
3.4. The Type of Cables
External switches such as footswitches can be connected
to the N-8031MS's external dial input terminals.
Terning on each switch connected to the terminal [7], [8],
[9], or [C] permits the same operation as performed by
pressing the dial [7], [8], [9], or [C].
An electrical current of 1 mA flows through each contact.
The types of cables are to be determined according to the
following conditions.
Note
The cable length from the external switch should not
exceed 3 m.

[Connections]
8 mm
• Twisted pair wires (such as those used for electronic
push-button telephone) are to be used for wiring
between the Exchange and the stations in principle.
• The number of cables pairs laid should be determined
considering the possibility of future expansion of the
system.
• Outdoor wires should be used where wiring passes
through inaccessible areas such as ceilings or under
floors where the maintenance is not performed. Indoor
wires may also be used, however, in case where there is
no risk of deterioration due to exposure to heat, etc.

3.6. Terminal Station Connection
3.7. Terminal Plug Connection
Mini-clamp connectors for line terminals and removable
terminal plugs for paging output terminal are supplied with
the N-8000EX/8010EX Exchange.
Perform each connector connection as follows.
Step 1. Strip a cable jacket of approx. 5 mm from the
cable end.

Cable
Step 2. With a pair of pliers, lightly pinch the mini-clamp
cover and, after ensuring that the cable is
securely inserted, firmly squeeze on the cover.
Note
Squeeze on the mini-clamp cover until it is
correctly locked.
Note
Do not solder plate on exposed inner cables
when using a stranded wire.
Step 2. Loosen the terminal screws and insert the cables.
Step 3. Tighten the terminal screws securely.
Notes
• Tug lightly on the cable to be sure that it does
not pull free. If the cable pulls free, loosen the
terminal screw again and reconnect from Step
2.
• To avoid stripping the screws, use the
screwdriver appropriate to the screws tightened
into the terminal plug.
Step 4. Insert the wired terminal plug into the pin header
on the N-8031MS's PC board.
