Example of an Alarm Contact Application
In this example, a horn is sounded whenever the Sunny Boy Control generates a
message. For this purpose, “Default Switch” under “Alarm Contact” must be
set to “contact 1_1”.
If the horn is also supposed to be sounded in the case of a power failure, it must be
connected to pin 7, and “Default Switch” under “Alarm Contact” must be set
to “contact 1_2”.
