Connecting control inputs
The CobraNet interface has 8 control inputs. The
control inputs can receive signals from third party
equipment that must trigger actions in the Praesideo
system. The control inputs can be configured to act on
contact make or on contact break (see section 43.7). It
also possible to supervise the cables for short-circuits
and open connections (see figure 7.3 and figure 7.4).
Whether a control input is actually supervised or not is
defined in the configuration.

damaged. Only use voltage-free contacts.

Connecting control outputs
The CobraNet interface has 5 control outputs. The
control outputs can be used to send signals to third party
equipment to trigger actions. Each control output
connection has three pins (see figure 7.5).

figure 7.5: Control outputs
The common (C) pin of the control output should
always be connected. Whether the other pin that is
connected is the normally closed (NC) or normally
open (NO) depends on which action that take place
when the control output is active (see table 7.1).

In the configuration, a purpose must be attached to the
control output that indicates the action to be taken when
it becomes active (see table 43.6).

Description
By default, the NC
contact is connected
with common contact
C. When the output is
activated, the NC
contact is opened.
By default, the NO
contact is not
connected with
common contact C.
When the output is
activated, the NO
contact is closed.
