ACCESSORY EQUIPMENT

LIGHT-ANNUNCIATOR CALL SYSTEM
If a light-annunciator call-in function is installed, the
optional Model SBL Switchbank panels have an annun-
ciator lamp above each station selector switch. Each sta-
tion has a call switch to light the appropriate lamp.
When lamp lights, move the corresponding switch to
"C" position. The intercom channel is now open for
normal intercom communication. The control panel
also has a built-in tone alert to provide audible annunci-
ation that supplements switchbank lamps.
PRIVACY FUNCTION
Prevents the console operator from monitoring the
speaker station if the station is provided with the op-
tional CA-l 1 CALL/PRIVACY Switch. A station in
the Privacy mode will still receive messages from the
consolette.
TIME TONE OPTION
The external single-circuit time clock closes contacts
that are normally open to activate the optional Time
Tone Module SST-l for timed, preset signals to station
speakers. Connects to terminal strip on the rear of the
control panel.
EXTERNAL BOOSTER AMPLIFIER
Model MT-60A or MT- 125B (60 or 125 watts) provide
increased power output. To install, remove the MCT-1
top cover and cut the jumpers on the terminal strip
between points A, B and C, D as shown in figure 5.
Insert two-conductor shielded cable in hole F. Connect
25 V balanced output leads to terminal strip points B
and C. Connect the shield to E. Attach the cable from
the Tape Out/Booster output jack on the rear of the
MCT-1 to the Hi-Z input of the MT-60A or MT-125B.
