Document Type and Number:
Japanese Patent JPH0789396
Kind Code:
B2
Abstract:
The fire alarm system consists of a receiver (R) and multiple of fire sensors (5) and relays (C), each having a CPU (10,60), a receiver circuit (11,61), a transmitter circuit (18,68), an instruction buffer (12,62) and an address buffer (13,63). Each relay (C) also has detectors (DE) and a terminal equipment (T). When the receiver (R) requires fire information from a certain terminal (S,C), each terminal equipment (S,C) compares the address designated by the receiver with its own address. Fire information will be sent back to the receiver only if the addresses coincide. In other cases, the CPU will be kept under the stand-by condition.
