Reference numeral 5 denotes a bell control signal transmitted to control the bell 202 and notified to the bell 202 via the communication processing circuit 106.

The operation of the lighting unit communication control system will be described below. As described above, the bell 202 is added as a component to the repeater 201 of this embodiment. In this configuration, when the primary power switch 204 is opened (OFF), the AC power monitoring circuit 108
The power supply stop is detected, and an AC power supply state monitoring signal 109 is output to the bell 202 and the communication processing device 106. Then, an alarm sound 203 is output from the bell 202, and the power supply state signal 20 indicating that the AC power supply is stopped from the communication processing circuit 106 to the monitoring device 205.
6 is output, and the monitoring device 205 recognizes that the AC power supply is in the supply stopped state.

At this time, when a person who hears the alarm sound 203 output from the bell 202 closes (turns on) the primary power switch 204, the AC power monitoring circuit 108 detects the recovery of the AC power supply and The monitoring device 205 outputs the status monitoring signal 109, and the monitoring device 205 inputs the power status signal 206 via the communication processing circuit 106 to recognize that the AC power supply has been restored.

When the supply of the AC power is stopped, the AC power monitoring circuit 108 detects the stop of the AC power supply, and outputs an AC power state monitoring signal 109 to the alarm sound monitoring timer 302 and the communication processing circuit 106. The alarm sound monitoring timer 302 causes the bell 202 to output an alarm sound 203 upon recognizing that the AC power supply has been stopped.

In this case, when the AC power is not restored even though the alarm sound 203 is output, or when the AC power is restored but the output of the alarm sound 203 from the communication processing circuit 106 is stopped. Bell control signal 20
