Document Type and Number:
Japanese Patent JP2023049742
Kind Code:
A
Abstract:
To provide a monitoring system which prevents a signal transmitted from a detector for detecting abnormality from being erroneously recognized as an overlapping signal and prevents processing corresponding to this signal from being not performed, and a receiver.SOLUTION: A fire monitoring system 1 includes a slave unit 10a and a relay 20. The slave unit 10a includes: a generation section for generating a signal; a determination section for determining a different value each time a new signal is generated; and a transmission section for transmitting a signal including this value. The relay 20 includes: a reception section for receiving a first signal and a second signal from an alarm within a predetermined time; and a limitation section for limiting processing corresponding to one of the first signal and the second signal in a case where the first signal and the second signal includes the same value and the first signal and the second signal are transmitted from the same slave unit 10a.SELECTED DRAWING: Figure 1
