5.1.7 Linking Group Addresses (3)

1. 6 fault signals should recall their own LED display in a KNX installation. A horn should
also sound when at least one of the fault signals occurs.
The application must be set as follows:
Number of used inputs: 6
 Used input objects: Inputs 1 to 6
 Type of logic operation: OR function, therefore inversion of the outputs: not
inverted.

The output group addresses control the actuator for the horn.
2. Two of the fault signals operate with inverted logic i.e. in the event of an alarm, they
send a ‘0’ telegram.
Parameter settings as before, however:
The inputs that receive these fault signals must be inverted.

3. The horn signal should be acknowledged with a switch sensor. The LED which
identifies the fault signal should however remain lit until the fault has been rectified. If
a new fault signal occurs during this period, the horn should sound again.
Parameter settings as before, in addition:
Output can be overwritten: permitted.
