Talkaphone KB-ML-5 User Manual

KB-ML-5 & KB-ML-10 Instructions

INSTALLATION

Place each station in the desired location. Run a separate length of TALK-A-PHONE #6303 (3-conductor
shielded) cable from each Sub-Station to the Master. With #6303 shielded cable, connect bare wire of
#6303 to terminal “R” on the Master and to terminal “3” on Sub. NOTE that wire from terminal “2” on each
Sub-Station connects to terminal number of the Sub-Station in the system. Note also that lead wires (of
matching colors to TALK-A-PHONE cable) extend from rear of model K-LR-3W, and are used for
connection. Models K-LR-3 and K-LR-3M have terminal strips.

Underneath the Master and Sub-Station is a cable clamp. Remove screw on cable clamp and pass
interconnecting cable underneath clamp. Adjust cable clamp so that it holds cable securely, and replace
screw.

The Master Station is powered by a separate power supply (included), which connects to the “+” and “-“
terminals on the terminal strip on the bottom of the unit. The black wire on the power supply connects to
the “-“ (minus) terminal, and the black with white stripe wire connects to the “+” (plus) terminal. Your
installation will require grounding of the unit itself. You can connect a ground wire from the “G” terminal
on that terminal strip to the screw on the metal cover plate of the power outlet. That screw is usually
earth ground. The power supply cord should be routed through the strain relief on the bottom of the
chassis.

Care should be taken that no part of the cable is too near electric or telephone wiring, etc., nor should it
be shorted to any grounded conductors, radiators, pipes, beams, etc., and the bare wire at the various
terminals should not short from one terminal to the other nor the metal chassis. When staples are used to
hold the cable in place, use only insulated staples and do not drive them in so hard as to cause the wires
inside the cable to short to each other.

CONTROLS

VOLUME CONTROL: Located at the left of the cabinet on the Master Station only. Rotate clockwise to

increase volume.

STATION SELECTOR SWITCHES: Located across front of the cabinet on the Master Station only. To
select Sub-Station corresponding to number above switch, push "in" with slight pressure. More than one
switch can be depressed at the same time. Return switches to “off” position by pushing again.

TALK-LISTEN CONTROL: Located on the right of the cabinet, (left on the K-LR-3W). Basically, push in
to “talk”; release to “listen”. (also see “private” and “non-private” operation of Sub-Stations in these
instructions.)

PERFORMANCE CONTROL: Located underneath Master Station, directly adjacent to front bumper foot.
Performance Control is locked into position by a locking bar. The Performance Control provides for
optional “private”-”non-private” operation of the Sub-Stations and is placed in one of two positions. When
control is placed in position towards the rear of unit, all Sub-Stations will function “non-privately”. System
is shipped from factory with Performance Control in “non-private” position and can be placed in “private”
position at any time. To change position of Performance Control, 1) Unscrew bumper foot alongside
Performance Control. 2) Remove locking bar. 3) Place Performance Control in the desired position. 4)
Place opening on one end of locking bar over Performance Control (Performance Control should protrude
through locking bar opening). Place opening on opposite end of locking bar over opening on chassis into
which the bumper foot fastens. 5) Screw bumper foot back into place. NOTE: Also see “private”-”non­private” operation of Sub-Stations in these instructions.

KB-ML-5 & KB-ML-10 Instructions

ALL-CALL CONTROL: Located underneath Master Station and so marked. All Call Control is easily

accessible with the index or forefinger of the right hand. When it is desired to call all Sub-Stations
simultaneously, place All Call Control in “on” position (toward front of unit). Upon completion of “All Call”,
return All Call Control to “off” position (toward rear of unit).

TRANSLUCENT INDICATOR: Located to left and below volume control knob on Master Station.
Indicates that unit has power.

OPERATION OF MASTER STATIONS

These systems have been designed for use where one Central Location must communicate with other
locations, but these other locations need not communicate with one another. ONE AND ONLY ONE
MASTER STATION CAN BE USED IN EACH KB-ML-5 or KB-ML-10 SYSTEM.

In Moderate to Low Noise Level Areas, use TALK-A-Phone Model K-LR-3 or K-LR-3W Sub-Stations.

For High Noise Level Areas, or In Very Large Locations, use TALK-A-PHONE Models K-C-20(V) or K-

HP-3(V) in place of Models K-LR-3, (W) Sub-Stations. Models K-C-20(V) will supply more than 3 times
as much volume. Model K-HP-3(V) will furnish more than twice the volume. K-C-20(V) is a Re-Entrant
Horn and is more directional than the K-HP-3(V).

Depress the station selector switch corresponding to the Sub-Station you desire to communicate with.
When you want to communicate with all of the Sub-Stations at once, use the “All Call” Control. Under
“non-private” operation, when not communicating with any Sub-Station, leave the station selector
switches in the “off” position (raised up) and you avoid listening to sounds coming from Sub-Station
locations (Sub-Stations can still call the Master). Upon completion of each conversation, return station
selector switches to “off” position.

Depress the Talk-Listen Control as far as it will go and “talk”. Release the Talk-Listen Control and “listen”.
Then adjust the Volume Control until desired volume is obtained.

OPERATION OF SUB-STATIONS

When System Is “Non-Private”: Sub-Station can answer the Master Station without any operation on

the part of the person at the Sub-Station, and at a distance from the Sub-Station. To originate a call from
a Sub-Station merely depress the Talk-Listen Control on the Sub-Station (use K-S-100(W) Origination-of­call Switch with K-HP-3(V) and K-C-20(V), and give your station number. Once the person at the Master
Station has answered you, there is no further need to operate the switch on the Sub-Station while
carrying on a conversation.

When System Is “Private”: Sub-Station can talk to the Master Station only when depressing the Talk­Listen Control on the Sub-Station (use K-S-100(W) Origination-of-call Switch with K-HP-3(V) and K-C­20(V). Therefore, the Master Station cannot listen-in on the Sub-Station.

Model K-HP-50 Power Booster can be added to the system at any time and connected to TALK-A­PHONE paging speakers, as Models K-LR-2 (R), K-HP-3(V), K-C-20(V). Use of the K-HP-50 will provide
a one-way paging circuit whereby any Master Station can page, but persons at the paging speakers
cannot reply or originate calls. Connect the K-HP-50 to its own station number in the system.

Close proximity of the Sub-Stations to the Master Station may result in a howl (acoustical feedback) when
either one calls the other. Reduce the volume on the Master Station or keep them partitioned from each
other. The Master Station controls the volume of the system with these models.
