PROGRAM SWITCHES
1.
Program Distribution. Functions when program
output selector is in SEND.
NORM(a1)
position pro-
vides switchbank control over program distribution.
ALL position distributes program to all rooms not con-
nected to the intercom.
2.
Program Output. SEND position enables program
distribution switch. SET position disconnects program
output from load for monitoring or presetting prior to
distribution. Does not offset intercom functions. The
program output switch should not be left in the SET
position. Once adjustment is made, switch should be
returned to SEND position.
SWITCH BANKS
MODEL SBS SWITCHBANK. Standard consolettes
are equipped with one or two Model SBS Switchbanks.
Each switchbank has 25 three-position lever switches
for connecting individual rooms to the system. Each
switch functions as follows:
A
-
(Up position)
-
Connects classroom speaker to
program channel for distribution of microphone, radio,
or phono program.
0
-
(Center position)
-
Disconnects classroom speaker
from system, except when consolette is operating in
Emergency mode.
C
-
(Down position)
-
Connects classroom speaker to
intercom channel.
MODEL SBL SWITCHBANKS (OPTIONAL). If
the system is equipped with an optional light-annunci-
ator call system, the consolette switchbanks will have
four-position lever switches. These switches operate
exactly as those in the Model SBS Switchbank, except
that there is a “B” (top) position of the switches which
is not used. If a switch is placed in the “B” position, it
functions exactly the same as in the “A” position.
