TRANSITIONAL MANAGEMENT OF CATASTROPHY DISPOSAL INSTITUTIONS

摘要

The transmission circuit comprises a receiver (RE) and multiple terminals including a relay (C) which has fire detectors (DE) and local bells (B). The receiver (RE) and terminals are connected by a signal line (L), and each terminal is called sequentially for information by the receiver. Both the receiver (RE) and the relay (C) has a transmission circuit (10,30) which consists of a memory (11,31), a signal sending means (12,32), a signal receiving means (13,33), and a discrimination means (14,34). The discrimination means (14,32) discriminate whether a signal actually sent agrees with a singal to be sent and stops signal transmission in case of disagreement.
