•
Normally Close/Open:
Here you can specify the behaviour of the inputs. Normally closed means
that the contact is closed in neutral position and reciprocally normally open means that the contact
is open in neutral position.
•
Latch Mode:
By ticking this option you will set the contact to be in latch mode. It means that you
will need on trigger to open/close the contact and one more trigger to get it back to the neutral
position.v
•
Monitor:
By ticking this option in contact or UGA monitoring mode, you will define an input as a
monitored logical input.
•
Event Setting:
By clicking start you will be able to associate an event to this input, see
to
learn more.
•
Monitor Mode:
With the drop down menu, you can choose between contact monitoring mode or
UGA mode. Contact monitor mode implies the use of an resistor network on a contact, see
To Create a Monitorable Button
. The UGA mode is based on polarizing the input with an external
24VDC source provided by external devices.
Note: The UGA mode is an alternative way of using contact. It does not offer real monitoring
behaviour and does not increase security.

External Fault Inputs
As explained before, the External fault Inputs have been implemented in order to offer the possibility to
force DIVA to enter his security mode. For more information about security mode, please read
The external trigger of those inputs should come from security devices such as security power supply.
You can also use those input to force DIVA into the security mode in order to save energy during
night.
Like any of the logic inputs, you can associate an event to External Fault Inputs.
