3. Configuration
By using jumpers it is possible to set on what kind of event should departure switch
react by closing or opening its contacts. The departure switch can react to three
different events: dep. switch on/off from the SWITCH 1, dep. switch on/off from the
SWITCH 2 and pick up/hang up the telephone line (means beginning and end of the
call).
The dep. switch contacts are available both normally open (between clips NO and C)
as well as normally closed (between clips C and NC). NC and NO in this case refers to
the contact state. see pic. above.
Example 1 – dep. switch operation by using password for SWITCH 2
Switching on and off is set to SWITCH 2. Dep. switch will close after receiving
password for SWITCH 2 (parameter ) and open after the switching time for 821
SWITCH 2 (parameter ) will elapse. If you set parameter to non-zero value, will 823 824
be also synchronized with SWITCH 1 (explained in the communicator manual).

Example 2 – dep. switch operation for unlimited time
Dep. switch closure is set to SWITCH 1, dep. switch opening to SWITCH 2. The dep.
switch will close when it has received the password for SWITCH 1 and will remain
closed until the communicator has received the password for SWITCH 2 and until the
switching time of SWITCH 2 elapses (parameter , it is recommended to set this 823
parameter as low as possible, which is 1s).
Example 3 – dep. switch closure for the duration of the call
Closure and opening is set to SPEAK. The dep. switch will close when the line is picked
up and open when the line is hung up. For the duration of the call the dep. switch will
be closed.
