NOTES:
A)
Button switches are momentary-action.
B)
Lamps are 12-14 volt, 80 mA.
C)
Relay is 12 volt DC, 100 mA maximum.
D)
When DIM and MUTE tallies are connected as shown above,
switch lamps will be illuminated at all times.
While it is unlikely that a "typical" installation will utilize all of these facilities, it is important to
understand what is available, along with the potential applications.
The DIM control input may be used to remote control the dim function of the Control Room Monitor
Module. Typical applications include equipping the Control Room door with a "door open" switch,
or a telephone set with an "off-hook" switch to automatically dim the Control Room speakers whenever
the door opens or the telephone is picked up.
