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 sub-
stations if this step is not taken.
