These switches may be set as needed; however, note the fol-
lowing points:
1. The position of dip switches affects only the master
station that the switches are located on.
2. Normally, all master stations should be set the same,
but it is possible to have different settings on each
master if needed.
3. Switches 6 and 7 (
CHIME
and
BUZZ
) should not be ON at
the same time.
4. Switch 2 (
BACK
) should not be OFF when other masters
have Switch 1 (
MUTE
) OFF, since the call tone may be
amplified twice, producing a disturbing noise should a
remote call occur during all-call use.
5. The dip switches are set at the factory as shown in
Section 1.8.

Call Tone Volume Adjustment:
The call tone volume control may be adjusted with a small

station. On the SM406 and SM411, the control is located
behind the removable button identification cover.
1.9 Terminal Reference for Master
Terminals—what they do and when you need them.
Connector 1
Brown (N): This is the Negative of the power supply, and
is necessary for system operation.
Red (B): This is used for the “all call” feature, and is
necessary when the PK401 all call relay is installed.
Yellow (A): This is used for the “all call” feature, and is
necessary when the PK401 all call relay is installed.
Green (P): This is the Positive of the power supply, and is
necessary for system operation.
Blue (D): This line activates the door release on the PK400
power supply, and is also used when the RY400 remote
control relay is installed.
Violet (F): When this line is shorted to the “N” connection
through a dry contact, the master switches from listen to
talk. (A selector button must be pushed in for this to work.)
Grey (R): This line is the input for background music from
the PK400, and is only needed when a background music
source is connected to the PK400.
White (C): This is the audio common, and is necessary for
system operation.
Black (L): When a master is communicating with another
master or remote, this line causes the
TALK
light to light red,
indicating that the system is in use. This line also disables
the amplifier on other masters until the master in
communication is switched off again. This line is necessary
for system operation.
Brown/White (M): This line is used for the
MONITOR
feature.
If this feature will not be used, this line can be omitted.
Red/White (X): This line is the selector line for this master.
This line is only used when there is more than one master
on the system. Connect the “X” connection to the numbered
terminal (1-11) on other master(s) that you want to use to
call this master.
Example: You want to be able to push button 3 on master
A or button 1 on master B to communicate with master C.
To do this you would connect the “X” terminal on master
C to Orange (3) on master A, and also connect it to Brown
(1) on master B.
Connector 2
This connector is the selector button connection for the
master, and is tied to the “X” terminals on other masters or
on remote stations.
Connector 3
These are auxiliary outputs for the selector lines, and are
used with the RY400 remote control relay and the RY402
in-use adapter. When a selector button is pushed, the
corresponding “K” connection goes positive to select the
correct relay output on the RY400, or to light the
IN
-
USE
light on remote stations so equipped.
Note: All master functions are controlled by the
TALK
light. If
the
TALK
light is illuminated red, the selected function will not
operate properly. Wait for the
TALK
light to go out before select-
ing any functions.
