DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, home security cis
The home telephone system 5a is connected to the home bus line 4 wired in common to each household from the home bus controller 6 to the home telephone device 5a.
5n and home security devices 1a-1n are connected, and each home security device 1a-1n has a fire sensor.
Sensors 2 such as 21, a gas leak sensor 22, and a security sensor 23 are connected. The home bus controller 6 is connected to the office line 9.

As shown in FIG. 2, each of the home security devices 1a to 1n receives a sensor input detecting section 8 connected to the sensor 2, an output of the sensor input detecting section 8 and an output of the address setting section 13. A main control unit 7, a display unit 12 and a sound output circuit 11 connected to the main control unit 7, a sound generator 10 driven by a sound signal from the sound output circuit 11, and a sound output circuit 11 Home bus extension line connection unit 16 for transmitting the output of the home bus to other home telephone devices 5a to 5n.
And a home bus data interface for transmitting and receiving data between main controller 7 and home bus line 4
14 and a connection portion 15 thereof.

Next, the operation of the home security system thus configured will be described with reference to the flowcharts of FIGS.

Step 1: For example, when the sensor 2 connected to the home security device 1a detects an abnormal state,
The sensor input detecting section 8 detects this abnormal state and transmits it to the main control section 7. Step 2: When the main control section 7 confirms the operation of the sensor 2, the display section 12 is operated immediately to display the occurrence of the abnormality. Step 3: The sound output signal generated by the sound output circuit 11 is output to the sound generator 10 of the main body 1a to generate an alarm sound. Note that the alarm sound emitted by the sound generation device 10 of the main body 1a has no effect on the other home security devices 1b to 1n.

Step 4: At this time, the home security device 1a connects to the home bus data interface 14
And through the home bus line 4, with respect to the other home security devices 1b~1n, etc. or state that is something onset report
Send a command to ask if Then, when the other home security devices 1b to 1n receive a command indicating that they are in a standby state in which no alarm is issued, the process proceeds to step 6.

Step 5: Another Home Security Device
When the 1b~1n is Ru comes back that the commands that are alarm, check the priority of the alarm contents, the case towards the alarm contents of the other home security device, priority than the self-low Step 6: The main control unit 7 also outputs the sound output signal of the sound output circuit 11 to the home bus extension line connection unit 16, and the main control unit 7 sends the sound signal to the home bus via the home bus data interface 14. A command to use the extension of the home bus line 4 is sent to the controller 6.

Step 7: Upon receiving this command, the home bus controller 6 connects the extension lines of the home telephone devices 5a to 5n to the extension lines of the home bus line 4. Step 8: An alarm sound is generated (reported) from each of the home telephone devices 5a to 5n.

Step 9: While the alarm contents of the home security device 11 are being output from the home telephone devices 5a to 5n, in step 5, another home security device is output.
When a high-priority alarm is generated from 1b to 1n, the home security device that has generated the new alarm sends a command for inquiring what is being issued, so the home security device 1a Outputs the content of the alarm currently being issued to the home bus line 4 and separates the sound output signal generated in the sound output circuit 11 from the extension line of the home bus 4.

Step 10: While the alarm is sounding, for example, each of the home security devices 1a to 1a through the home telephone device 5a.
When the alarm stop key 3 for sending the alarm sound stop command is pressed for 1n, Step 11: The home security which issues the highest priority alarm
Utility device 1a, upon receiving the command, it is judged that there is an alarm sound stop input, Step 12: The alarm sound is stopped, it sends a stop command for the warning to the home bus line 4. Note that the home security devices 1b to 1n that have not output an alarm sound or have issued an alarm sound that is not the highest priority ignore the alarm sound stop command from the home telephone device 5a.

Step 13: Even if the home security device 1a, which has issued the highest priority alarm, sends a command to stop the alarm sound, if the other home security devices 1b to 1n have issued the alarm, Returning to step 4, the command is received, and the operation for outputting the command to each of the home telephone devices 5a to 5n is performed in the same manner as when a new alarm is generated, and the alarm sound is switched to the next highest priority alarm sound.

Note that if the home security device 1a that issues the highest priority alarm also issues another alarm at the same time, the highest priority alarm sound is stopped and the time when a new alarm is generated is determined. Similarly, each home telephone device 5a-5n
, And switch to the next highest priority alarm sound.

The operation of stopping the alarm sound from the home telephone devices 5a to 5n can be performed as many times as possible until the output of the alarm sound from the home telephone devices 5a to 5n stops.

Each of the home security devices 1a to 1n is provided with an address setting section 13. By setting different addresses that do not overlap each other, it is possible to identify which home security device has transmitted the command. be able to. If a duplicate address is set by mistake, it is not output from the second home security device to the home telephone devices 5a to 5n, so that it can be easily found by a test during construction.
