7.4.4Connecting 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.

Note

Do not combine control input wires of multiple control inputs (e.g. do not use a common return wire).

7.4.5Connecting 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).

Warning

Do not connect DC or AC signals to the control inputs, otherwise the input circuit may be damaged. Only use voltage-free contacts.

table 7.1: Control outputs details

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

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).
