PURPOSE:To obtain an alarm detecting system where the constitution of a monitoring controller is simplified and alarm detecting time is shortend. CONSTITUTION:Plural monitored devices 10 are devided into a plurality of groups 20 and OR circuit 11 logically adds the alarm signal of the respective monitored devices 10 of the respective groups 20. Besides, the monitoring controller 1 is provided with MPU 1, an input interface circuit 4 and a serial communication interface circuit 2. The monitoring controller 1 judges a group 20 which a monitored device 10 sending the alarm belongs to with the input interface circuit 4 and serially communicate to all the monitored devices 10 belonging to the group 20 with the serial communication interface circuit 2 to detect an alarm device. |
