Then, the abnormality information is reported to the security center 4 in this state. The security center 4 receiving the abnormal information takes necessary measures such as dispatching a security guard.

Next, the operation of changing the telephone number of the security center registered in the security device 1, which is a feature of the present invention, will be described with reference to the flowcharts of FIGS. 5 and 6 show the operation of the security device 1, and FIGS. 7 and 8 show the operation of the setting transmitter 2. The number of steps used in the following description is distinguished using the 100s in FIGS. 5 and 6 and the 200s in FIGS. 7 and 8.

When trying to change the telephone number setting,
The operator (maintenance staff) previously sets the RAM 21 of the setting transmitter 2
2 stores the house code of the security device 1 whose operation is to be changed by operating the operation unit 23 (S200). Then, the user carries the setting transmitter 2 and carries it to the vicinity of the security device 1 outside the house 6. Here, the house code is a personal identification code for identifying the security device 1 and, although not shown, is assigned to each security device 1 when there are a plurality of security devices.

The operator depresses the patrol button 231 constituting the operation unit 23 of the setting transmitter 2 (step S20).
By 1), the operation is started. When receiving the operation signal from the operation unit 23, the control unit 21 of the setting transmitter 2 transmits the tour signal stored in the RAM 212 in advance to the transmission unit 24.
The signal is transmitted as a low-power radio signal having a predetermined frequency (step S202). This tour signal includes the house code of the security device 1. After that, it waits for a mode change signal to be received from the security device 1.

The security device 1 installed in the house 6 receives the traveling signal by the receiving unit 15 (step S101).
Then, the control unit 11 compares the house code set in the house code storage unit 115 of the RAM 112 in advance with the house code included in the received traveling signal (step S
102), if they match, after setting the security device 1 to the traveling mode (step S103), the transmitting unit 14 transmits a mode change signal (step S104). If they do not match, a mode change disapproval signal is transmitted (step S105). As described above, since the tour mode is not set unless the house codes match, there is no intentional or accidental transition to the tour mode.

In the setting transmitter 2, when the receiver 25 receives the mode change signal (Y in step S203).
Displays a screen for inputting a command on the liquid crystal display 26 of the display unit 22 (step S204), and waits for input of a change command (step S206). Also,
When a mode change disapproval signal is received (step S20)
3N) indicates to that effect on the liquid crystal display 2 of the display unit 22.
6 (step S205), and returns to step S200.

The operator looks at the liquid crystal display 26,
After confirming that the security device 1 has been set to the patrol mode, next, for example, “1” and “confirm” are input as commands for changing the setting of the telephone number using the ten keys 232 constituting the operation unit 21. When this change command is input, the process proceeds from step S206 to step S207, where the control unit 21
To display a screen for entering a telephone number. The operator inputs the telephone number of the security center 4 to be newly set by using the ten keys 232 constituting the operation unit 23 (step S208). The telephone number may be stored in the RAM 112 in advance and used.

The input telephone number is coded into a radio signal and transmitted together with the change command from the transmission unit 24 (step S209), and then waits for reception of a change confirmation signal from the security device 1. In the security device 1, the receiving unit 1
5 to receive a change command signal (step S10).
6), the control unit 11 once stores the telephone number included in the change command signal in the RAM 112, performs a report test to the security center 4 using the telephone number, and determines the test result (step S107). . In this report test, dialing is performed using the telephone number received by the report unit 16. If the telephone number is the correct telephone number of the security center 4, the communication state is established with the computer of the security center 4, and a test signal is automatically sent from the security device 1 to the security center 4, and the security center 4 The computer sends a confirmation signal to the security device 1. When the security device 1 receives this confirmation signal,
Report test is OK, NG if not received within a predetermined time
Is determined. In this way, when the telephone number is changed, the security center 4 is notified, so that the security center 4 can know that the telephone number has been changed in the security device 1.

When the report test is OK (Y in step S107), the security device 1 stores the telephone number in the RAM1.
The information is registered in the notification destination telephone number storage unit 114 (step S108), and a change completion signal is transmitted from the transmission unit 14 (step S110). On the other hand, when the report test is NG (N in step S107), an unchanged signal is transmitted.
As described above, the security device 1 automatically checks that the received telephone number is correct, so that it is possible to prevent a change to an incorrect telephone number.

In the setting transmitter 2, when the receiving section 25 receives the change completion signal, a message "Telephone number has been registered" is displayed on the liquid crystal display 26 of the display section 22 (step S211). . When confirming this message, the operator presses the patrol button 232 again to release the patrol mode of the security operation 1 and set the security mode or the security release mode as the previous state. Then, a transmission end signal including the house code stored in the RAM 212 is transmitted from the transmission unit 24 (Step S).
212). Unchanged signal (N in step S210)
Is received, the process returns to step S208 and waits for the operator to input a telephone number again.

In the security device 1, when the patrol end signal is received by the receiving unit 15 (step S111), processing for terminating the patrol mode and setting the security mode or setting the security release mode is performed (step S112). . This processing checks whether or not the house code included in the received patrol end signal matches the house code stored in advance in the house code storage unit 115 of the RAM 112. If the house code matches, the security device 1 is activated. The mode is shifted from the patrol mode to the security mode or the security release mode. As described above, by using the house code as the personal identification code, it is possible to prevent the transition to the security mode before the change setting of the telephone number is completed.

According to the embodiment described above, the operation of changing the telephone number of the security center stored in the security device 1 can be easily performed from outside the house outside the security area.
