3.5.2 Activating the external detectors
If an alarm card is installed in the system, then the detectors can be switched on under Digital
I/O

Alarm detectors.
If the card inputs should only be used as detectors, then the detector type must be
selected. After doing this, assign the detector a unique name.
The “Break contact” function is used to define the detector behaviour.
When this function is not activated, the detector functions as a Normally Open contact as
standard (“OK” status) and is closed in the event of an alarm (“Alarm” status). The detector
functions as a Normally Closed contact when this function is activated, meaning its functions
are inverted.
Using the detector as a key switch:
When a detector is defined as a key switch ( ), then timers can be connected to it. These are
only activated when the detector has the “Alarm” status.
The following steps show the set-up of a key switch detector:
1. Open the system configuration
2. Access the Digital I/O menu point
3. Select the detector category to be used for the key switch function
4. Switch the status (“Off”, “Alarm”, “Key switch”) to Key switch
5. Save your settings
You can now link the detector to the desired timer using the Actions

Timers menu point.
