Control inputs
Control inputs can be used to receive signals from third party equipment that must trigger
actions in the PRAESENSA network.
Control inputs can be configured to act on contact make or on contact break. It is also
possible to supervise the connected cables for short‑circuits and open connections. Whether a
control input is actually supervised or not is defined here in the configuration.

For connection options, see the PRAESENSA installation manual. For an actions type overview,

Actions (1-5) in the following table.
– The sub‑calls can have different priorities and zones /zone groups, but have the same
activation behavior.
