Abstract
In a danger alarm system, such as a fire alarm system, the availability of the system is increased by decentralization of the system intelligence. For this purpose, the entire system is subdivided into small system modules which are fully functional in and of themselves. Each system module has connection installations for one or more alarm circuits or one or more subordinate system modules, a programmed control for interrogation and evaluation of alarm signals, as well as connections for display operation and registration elements. One of the system modules serves as the central station, as the remaining system modules are subordinate to the central station in one or more hierarchical levels.
