[Example 1]
For example, a case where the CPU 46 of the dwelling unit master 4a is set to the first control function will be described. This first control function functions when a resident performs a security / warning setting operation on the operation unit 43 of the dwelling unit 4a when going out.

  In such a state, when the security sensor 6a detects the intrusion of a suspicious person, a sensor detection signal S1 is transmitted to the CPU 46 via the security sensor input detection circuit 601 of the dwelling unit 4a. The CPU 46 outputs a video signal informing the security alarm to the display unit drive circuit 441 based on the sensor detection signal S1 and outputs a security alarm signal informing the security alarm to the loudspeaker amplifier 411. Therefore, the security alarm is displayed on the display unit 44. Then, a security alarm sound is output from the loudspeaker 41, and at the same time, the mode is switched to the recorded image erasure operation prohibition mode. Therefore, since the CPU 46 denies access to the recorded image storage device 49 in which the recorded images taken by the collective entrance machine 1, the entrance unit with camera 5a, and the monitoring camera 7a are stored, the recording is performed in the security alarm state. It is possible to prevent the recorded image stored in the image storage device 49 from being erased by the operation unit 43 of the master unit due to an operation by a suspicious person or carelessness of a resident.

When the fourth control function is set in the CPU 46, the erasure prohibition of the recorded image can be canceled after the erasure prohibition release time elapses. In addition, when the fifth control function is set in the CPU 46, when a crime prevention alarm release operation for access control is performed by the operation unit 43 of the dwelling unit 4a, the crime prevention alarm release signal S3 is sent to the operation signal transmission circuit 431. Therefore, the CPU 46 can reset the security alarm to the initial setting based on the security alarm cancellation signal S3 and cancel the recorded image erasing operation prohibition mode. Further, when the sixth control function is set in the CPU 46, until the security alarm is output by the CPU 46 when the security sensor 6a detects the intrusion of the suspicious person (when the security alarm is output). Since the recorded image stored in the recorded image storage device 49 can be switched to the storage protection state, the crime prevention function can be enhanced.
[Example 2]
Next, a case where the CPU 46 of the dwelling unit master 4a is set to the second control function will be described. This second control function is effective when a single dwelling unit is provided with a plurality of security sensors. Like the first control function, the resident is alerted by the operation unit 43 of the main unit 4a when the resident is out. Functions when a setting operation is performed.

  In such a state, when the security sensor 6a detects the intrusion of a suspicious person, a sensor detection signal S1 is transmitted to the CPU 46 via the security sensor input detection circuit 601 of the dwelling unit 4a. The CPU 46 outputs a video signal informing the security alarm to the display unit drive circuit 441 based on the sensor detection signal S1 and outputs a security alarm signal informing the security alarm to the loudspeaker amplifier 411. Therefore, the security alarm is displayed on the display unit 44. Then, a security alarm sound is output from the loudspeaker 41, and at the same time, the mode is switched to the recorded image erasure operation prohibition mode. Therefore, the CPU 46 stores the recorded image of the suspicious person's recorded image captured by the surveillance camera 7a, the collective entrance machine 1, and the camera-equipped slave unit 5a associated with the security sensor 6a that has detected the intrusion of the suspicious person. Since the access to the storage device 49 is denied, the recorded image of the suspicious person stored in the recorded image storage device 49 is displayed on the operation unit 43 of the master unit due to the operation by the suspicious person or the carelessness of the resident. It can be prevented from being erased.

Note that the control operation of the CPU 46 when the fourth control function, the fifth control function, and the sixth control function are set is the same as that in the first embodiment, and thus the description thereof is omitted.
[Example 3]
Next, a case where the CPU 46 of the dwelling unit master 4a is set to the third control function will be described.

  When the security sensor 6a detects the intrusion of a suspicious person, a sensor detection signal S1 is transmitted to the CPU 46 via the security sensor input detection circuit 601 of the dwelling unit master 4a. The CPU 46 outputs a video signal informing the security alarm to the display unit drive circuit 441 based on the sensor detection signal S1 and outputs a security alarm signal informing the security alarm to the loudspeaker amplifier 411. Therefore, the security alarm is displayed on the display unit 44. Then, a security alarm sound is output from the loudspeaker 41, and at the same time, the mode is switched to the recorded image erasure operation prohibition mode. The CPU 46 transmits the sensor detection signal S1 to the dwelling unit base line L1 via the communication IF circuit 48 in order to transmit the sensor detection signal S1 to the management unit base unit 2 installed in the management room. When the sensor detection signal S1 transmitted to the dwelling unit master line L1 is received by the management room master unit 2 via the first communication circuit 31 → the main control circuit 34 → the third communication circuit 33 of the controller 3 In the management room base unit 2, it is notified that the security alarm has been issued at the unit where the base unit 4 a is installed. At this time, for example, the dwell unit number of the dwell unit parent unit 4a is displayed on the display unit 24 of the management room main unit 2 as information on the dwell unit where the security sensor 6a is installed.

  After the manager in the control room confirms the dwell unit number together with the security alarm from the dwell unit base unit 4a, if the operation unit 22 of the control unit base unit 2 performs the recorded image view operation for the dwell unit base unit 4a, the recorded image view signal S4 is displayed. The data is transmitted to the dwelling unit parent machine line L <b> 1 via the third communication circuit 33 → the main control circuit 34 → the first communication circuit 31 of the controller 3. When the communication IF circuit 48 of the dwell unit master 4a receives the recorded image browsing signal S4 transmitted to the dwell unit base line L1, the recorded image browse signal S4 is output to the CPU 46, so the CPU 46 outputs the recorded image browse signal. Based on S4, the recorded image stored in the recorded image storage device 49 is taken out and transmitted to the management room master unit 2 through the same route as the sensor detection signal S1. In the management room master unit 2, the recorded image is displayed on the display unit 24.

  Thereafter, when the administrator performs a security alarm canceling operation for restoring the security alarm of the dwelling unit master 4a with the operation unit 22 of the control room master unit 2, the security alarm canceling signal S5 is transmitted to the third communication circuit 33 of the controller 3. The data is transmitted to the dwell unit base line L1 via the main control circuit 34 → the first communication circuit 31. When the communication IF circuit 48 of the dwell unit base unit 4a receives the security alarm release signal S5 transmitted to the unit L1 line L1, the security alarm release signal S5 is output to the CPU 46, so the CPU 46 outputs the crime prevention alarm release signal. Based on S5, the security alarm can be reset to the initial setting and the recorded image erasing operation prohibition mode can be canceled.

Note that the control operation of the CPU 46 when the fourth control function, the fifth control function, and the sixth control function are set is the same as that in the first embodiment, and thus the description thereof is omitted.
[Example 4]
Next, the case where the CPU 46 of the dwelling unit master 4a is set to the seventh control function will be described.

  For example, when a resident of a dwelling unit in which the dwelling unit master 4a is installed finds a suspicious person and presses the emergency button 45 of the dwelling unit parent unit 4a, the emergency button operation signal S2 detects the emergency button input of the dwelling unit parent unit 4a. It is transmitted to the CPU 46 via the circuit 451. The CPU 46 outputs a video signal for notifying the display unit drive circuit 441 of an emergency alert based on the emergency button operation signal S2 and outputs an emergency alert signal for notifying the loudspeaker amplifier 411 of the emergency alert. An emergency warning sound is output from the loudspeaker 41, and at the same time, the mode is switched to the recorded image erasure operation prohibition mode. Therefore, since the CPU 46 denies access to the recorded image storage device 49 in which the recorded images taken by the collective entrance machine 1, the entrance unit with camera 5a, and the monitoring camera 7a are stored, the recording is performed in the emergency alarm state. It is possible to prevent the recorded image stored in the image storage device 49 from being erased by the operation unit 43 of the parent device due to carelessness of a suspicious person or resident.

Further, when the ninth control function is set in the CPU 46, the erasure prohibition of the recorded image can be canceled after the erasure prohibition release time elapses. Further, when the tenth control function is set in the CPU 46, when an emergency alarm canceling operation for access control is performed by the operation unit 43 of the dwelling unit master 4a, an emergency alarm canceling signal S30 is generated as an operation signal transmission circuit 431. Therefore, the CPU 46 can reset the emergency alarm to the initial setting based on the emergency alarm cancel signal S30 and cancel the recorded image erasing operation prohibition mode. In addition, when the eleventh control function is set in the CPU 46, when the emergency button 45 is pressed (when an emergency alarm is output), the recorded image is stored before the CPU 46 outputs the emergency alarm. Since the recorded image stored in the device 49 can be switched to the preservation protection state, the crime prevention function can be enhanced.
[Example 5]
Next, a case where the CPU 46 of the dwelling unit master 4a is set to the eighth control function will be described.

  For example, when a resident of a dwelling unit in which the dwelling unit master 4a is installed finds a suspicious person and presses the emergency button 45 of the dwelling unit parent unit 4a, the emergency button operation signal S2 detects the emergency button input of the dwelling unit parent unit 4a. It is transmitted to the CPU 46 via the circuit 451. The CPU 46 outputs a video signal for notifying the display unit drive circuit 441 of an emergency alert based on the emergency button operation signal S2 and outputs an emergency alert signal for notifying the loudspeaker amplifier 411 of the emergency alert. An emergency warning sound is output from the loudspeaker 41, and at the same time, the mode is switched to the recorded image erasure operation prohibition mode. Further, the CPU 46 transmits the emergency button operation signal S2 to the dwelling unit master line L1 via the communication IF circuit 48 in order to transmit the emergency button operation signal S2 to the management room master unit 2 installed in the management room. The emergency button operation signal S2 transmitted to the dwelling unit base line L1 is received by the management room base unit 2 via the first communication circuit 31 → the main control circuit 34 → the third communication circuit 33 of the control unit 3. Then, in the management room base unit 2, it is informed that an emergency alarm has occurred at the unit where the unit base unit 4a is installed.

  After the manager in the management room confirms the emergency alarm from the dwelling unit master 4 a and performs the recorded image browsing operation with the operation unit 22 of the management room base unit 2, the recorded image browsing signal S4 is the third communication of the controller 3. The signal is transmitted to the line L1 for the dwelling unit via the circuit 33 → the main control circuit 34 → the first communication circuit 31. When the communication IF circuit 48 of the dwell unit master 4a receives the recorded image browsing signal S4 transmitted to the dwell unit base line L1, the recorded image browse signal S4 is output to the CPU 46, so the CPU 46 outputs the recorded image browse signal. Based on S4, the recorded image stored in the recorded image storage device 49 is taken out and transmitted to the management room master unit 2 via the first communication circuit 31 → the main control circuit 34 → the third communication circuit 33 of the controller 3. To do. In the management room master unit 2, the recorded image is displayed on the display unit 24.

  Thereafter, when the administrator performs an emergency alarm canceling operation for restoring the emergency alarm of the dwelling unit master 4a with the operation unit 22 of the control room master unit 2, the emergency alarm canceling signal S50 is sent to the third communication circuit 33 of the controller 3. The data is transmitted to the dwell unit base line L1 via the main control circuit 34 → the first communication circuit 31. When the communication IF circuit 48 of the dwell unit master 4a receives the emergency alarm cancel signal S50 transmitted to the dwell unit base line L1, the emergency alarm cancel signal S50 is output to the CPU 46, so the CPU 46 outputs the emergency alarm cancel signal. Based on S50, the emergency alarm can be returned to the initial setting, and the recorded image erasing operation prohibition mode can be canceled.

  Note that the control operation of the CPU 46 when the ninth control function, the tenth control function, and the eleventh control function are set is the same as that in the fourth embodiment, and thus the description thereof is omitted.

  Further, in the above-described embodiment and FIG. 1, a plurality of dwelling units are connected to the dwelling unit line. However, the present invention is not limited to this, and only one unit is connected as described above. Actions and effects can be obtained.
