摘要
The system has a central module for feeding and operational mode switching of a double-wire loop. A central feeding and operational mode switching module registers an individual line and loudspeaker fault using a function maintaining and securing module installed at an alarming loudspeaker. The switching module switches to a two-way operation in response to registration for function maintenance. A faulty transmission chain with exception of defective parts functions again within seconds. Ground fault control is present for securing protection against accidental contact.
