K-S-112X INSTALLATION & OPERATION MANUAL
INSTALLATION WITHOUT A SUB-STATION SPEAKER
If you are only connecting one K-S-112X, use the instructions below for connecting on a
separate channel. If more than one K-S-112X is connected to a Master and no substation speakers are connected to the K-S-112X's, you can either give each unit its own
channel or connect some or all on the same channel.
Connecting K-S-112X on a separate channel
Run an individual line of Model 6303 (1 shielded pair) cable from each K-S-112X to
Master as shown in Figure 1. Connect the two terminals marked MASTER on each KS-112X to the appropriate terminals on the Master model in use (See Master's
instructions relating to connection of a sub-station without call origination). No
connection to the two terminals marked "SPKR" on the K-S-112X is needed.

Connecting multiple K-S-112X's on the same channel
Connect one K-S-112X to another in series, as shown in Figure 2, using Model 6303 (1
shielded pair) cable. Connect the two terminals marked MASTER on the first K-S-112X
to the two terminals marked SPKR on the second K-S-112X. Continue in this fashion
until the last K-S-112X. On this unit, connect the two terminals marked MASTER to the
appropriate terminals on the Master or Junction Box for the Master model in use (see
Master's instructions relating to connection of a sub-station without call origination).
An alternative for sharing the same channel is to run a separate cable for each K-S112X and connect in parallel back to the same terminals on the Master or Junction Box.

K-S-112X INSTALLATION/OPERATION

INSTALLATION WITH A SPEAKER SUB-STATION
A speaker sub-station, working in conjunction with the K-S-112X, is needed for a Master
to call the K-S-112X location. Many Talk-A-Phone sub-stations are available.
Place the speaker sub-station so it provides the coverage desired. Place the K-S-112X
at operating level near the speaker sub-station. Run a line of Model 6303 (1 shielded
pair) cable from the sub-station to the SPKR terminals on the K-S-112X; then run a line
of cable from the MASTER terminals on the K-S-112X to the Master or Master's junction
box (see Figure 3).

Special Instructions for Hands-Free Masters
All Automation Masters (those using TAP-200 or TAP-200C Amplifiers or TAP-1 or
TAP-6 Masters) must Remove the l0 ohm, 10 watt resistor from terminals LB and LG on
the TAP-200/TAP-200C Amplifier or TAP-1/TAP-6 Master. Instead, install a l0 ohm
resistor of this type across the audio cable line going to each speaker sub-station in the
system. (NOTE: Do not attach a resistor to signal line of sub-stations with call
switches). The K-S-112X will not function in Automation systems using speaker substations if this step is not taken.
