The signals of the digital outputs are switched via potential-free relay contacts. The
contacts are controlled "fail safe", ie, in the event of an alarm, the current at the
relay coil drops and the NO contact (normally open) is opened. The wiring diagrams
in chapter 5 show the relay contacts in the de-energized state.
