Emergency light installation with interface function for building management systems and associated communication method

摘要

The emergency lighting system (1) has an interface device (51) and two emergency lights (19,21), where the emergency lights and the interface device are transferred on the state data by a radio channel (55). An output contact (63) is formed as a collective fault contact which attains in an on-state in a power failure in a control circuit of a switch of the collective fault contact. The data are forwarded through a condition of the latter emergency light via the former emergency light. Independent claims are included for the following: (1) a process for converting data of an emergency lighting system; and (2) a process for inserting an activation signal, for example a fire alarm input, in a data tuple of an emergency lighting system.
