• Before securing the screw, make sure that you do not need to program the external unit and make sure that the metal front panel does not rub against other metal parts, with consequent risk of damage to its insulating coating.
• While the system is running, take care not to accidentally call users when replacing the nameplate labels.

Operation with additional external units

• External unit with switching device art. 1404: default programming to be used with single external unit or with multiple external units connected with switching device art. 1404.
• Secondary external unit: function to be used in systems with switching device art. 1405 and 2 external units.
• Main external unit: function to be used in systems with switching device art. 1405 and 2 external units.

Operation with switching device 1404 (default)

With the switching device 1404 it is possible to install 2 or more external unit.
In the configuration of art. 1404, the MIN and MAX DIP-switches define respectively the lowest and highest user codes which can be connected to the riser. For information on setting the desired values, refer to the addressing table.
Separate switching devices for dierent risers must manage code ranges which are not overlapping.
The self-ignition command will activate the camera of the external unit. Further self-ignition commands will toggle between 2 (max) external units, activating them alternately.
For the diagrams, please refer to the Audio/Video kit system section in the system manual

Operation with switching device 1405

With the switching device 1405 it is possible to install only 1 main external unit and 1 secondary external unit.
In “Main external unit” mode, lock-release (or actuator) commands are only executed if the external unit is in call or self­ignition mode. The "door-open" function is always deactivated.
In “Secondary external unit” mode, lock release (or actuator) commands are executed if the system is in standby mode or if the external unit is active.
If the system is in standby mode the first self-ignition command will activate the camera of the secondary external unit. Further commands will toggle between 2 (max) external units, activating alternately the main external unit and the secondary external unit.
For the diagrams, please refer to the Audio/Video kit system section in the system manual
