Numeral 30n denotes one or more notification devices. The notification device 30n notifies a person who has entered the security target area of a necessary message, and when a notification signal is input, notifies the message in accordance with the input notification signal.

Reference numeral 40 denotes a mechanical security device which mechanically guards a security target area based on the sensor 10 and which can be switched to a security state or a security release state by operating security switching means (not shown). The security signal and the security release signal are output to the transmission unit 21 of the device 20. Also, when an abnormal signal is input in the security state, the remote monitoring center 5
Report to 0 mag. Further, the state of the sensor is displayed by an LED or the like.

Next, the configuration of the repeater 20 will be further described. Upon receiving the detection signal from the sensor 10n, the transmission / reception unit 21 of the repeater 20 outputs the detection signal to the control unit 22. When an abnormal signal is input from the control unit 22, the abnormal signal is output to the mechanical security device 40. When a security state is input from the mechanical security device 40 by a security switching operation, a signal indicating the security state is output to the control unit 22.

When the control unit 22 receives a security signal from the transmission / reception unit 21 indicating a security state or a security release signal indicating a security release state, the security switches to the security state or the security release state. When a detection signal from the sensor 10 n is input from the transmission unit 21, a timer start signal is output to the timer 24 in a security state. If the timer release signal is input before the timer start signal is output and the timer end signal is input, a reset signal is output to the timer 24 to switch to the security release state. Timer 24
When the timing end signal is input from the
Output to

The transmitting section 23 is connected to the power line 60,
When receiving the notification signal from the control unit 22, the control unit 22 outputs the notification signal to the notification unit 30n via the power line. Note that the transmission / reception unit 23 and the power line 60 are connected via the connector 35.

The timer 24 starts counting when it receives a timing start signal from the control unit 22, and outputs a timing end signal when a preset time has elapsed. When a reset signal is input during timing, the timing ends.

The storage unit 25 stores the notification device 30n corresponding to the sensor 10n as each address. Further, the storage unit 25 stores a message to be notified by each notification notification together with a voice number.

The notification means 30n is connected to the power line 60 wired in the security target area. When a notification signal is input from the transmission unit 23 via the power line 60, the notification means 30n notifies a voice corresponding to the notification signal.

First, when the sensor 10n detects a person, it outputs a detection signal to the transmission / reception unit 21 of the repeater 20. The transmitting / receiving unit 21 that has received the detection signal from the sensor 10n outputs the detection signal to the control unit 22 (S101). The control unit 22 that has received the detection signal determines whether the state is the security state or the security release state.
(S102) If it is in the security state, the address of the notification device corresponding to the sensor that has output the detection signal is read from the storage unit 25, and the notification signal to which the address and the notification voice number are added is output to the transmission unit 23 (S103). The notification device 30n that has input the notification signal determines that the added address is its own,
A voice corresponding to the added notification voice number, for example, "Security is in progress. Please release security" is reported. Also,
The control unit 22 outputs a clock start signal to the timer 24 (S10
Four). The timer 24 that has received the clock start signal starts clocking.

When the user who has heard the sound from the notification device operates the security switching device of the mechanical security device 40 to perform a security release operation, and when the mechanical security device 40 is in the security release state, the mechanical security device 40 becomes a repeater. The security release signal is output to the transmission / reception section 20 of the communication device 20. The transmission / reception unit 21 that has received the security release signal from the mechanical security device 40 transmits the security release signal to the control unit 22.

The timer 24 that has received the reset signal ends the time measurement. Further, the control unit 22 outputs a notification end signal to the transmission unit 23 (S107). The transmitting unit 23 that has received the notification end signal outputs the notification end signal to the notification device 30n. The notification device 30n that has received the notification end signal ends the notification.

However, when the timing end signal is input to the control unit 22 before the security release signal (S108), the control unit 22 outputs an abnormal signal to the transmission / reception unit 21 (S10).
9). Transmission / reception unit 21 that has received an abnormal signal from control unit 22
Outputs the abnormal signal to the mechanical security device 40. The mechanical security device 40 that has input the abnormal signal from the transmission / reception unit 21 of the repeater 20 notifies a monitoring center (not shown) such as a security company. The monitoring center that has received the report responds by dispatching a supervisor.

In this embodiment, a timer is provided in the repeater 20. However, a timer unit is provided in the notifying device 30n, and a time-measuring start signal is input when starting the notifying, and a preset time is set.
