Connecting control outputs
The network controller 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 5.10).

place when the control output is active (see table 5.5).
place when the control output is active (see table 5.5).
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). Control outputs 4 and
5 of network controllers of version HW15/xx and
higher already have a fixed purpose (see table 5.6).

5.3.10 Connecting RS232 port
The network controller has a RS232 connector for
production and development purposes. Do not use this
connector in installed Praesideo systems, with the
following exception. The PRS-NCO-B comes with a
dedicated buzzer for audible fault and voice alarm
notifications. This buzzer comes with a connector to
power it from the RS232 port. See section 32.9.

For fail-safe behavior, these fixed control outputs
For fail-safe behavior, these fixed control outputs
are energized in the default (faultless) situation,
so NC is open and will be closed if a fault
occurs.
