C. Operation of Embodiment Next, the operation of the disaster prevention monitoring system having the above-described configuration will be described with reference to FIG. Here, fire detector 1
When the is activated, when a fire is confirmed,
The operation and the inspection operation when an abnormality occurs in the house information board 2 will be referred to.

(1) Operation when the fire detector 1 is activated Operation on the repeater 6 side When the fire detector 1 detects smoke or heat due to a fire in a dwelling unit, a warning signal is generated and the relay 6 The receiving circuit 10 receives this. Then, the circuit 10 drives the photocoupler light emitting portion 10a to drive the corresponding photocoupler light receiving portion 1a.
0b is turned on, and the mode signal indicating the sensor operation is output to the next stage. As a result, the terminal T1 of the repeater 6
The "first report" is given to the signal line L1 connecting the terminal and the terminal R1 of the housing information panel 2, and the receiving circuit 10 sends the "sensor operation (first report) mode" to the next-stage audio circuit 12.
To instruct to speak a voice message. Then, in this case, the voice circuit 12 utters a voice message "Fire detector has activated. Please confirm." From the speaker SP1.

Operation on the side of the house information board 2 When the "first report" is received via the signal path L1, the house information board 2 receives a "fire detection" from the speaker SP2 via the amplification section 21 under the instruction of the control section 20. The instrument has been activated. Please check. "Is output.

(2) Operation when a fire is confirmed (a) When the judgment switch SW2 is operated Operation on the housing information board 2 side In this way, the "first report" is issued from the housing information board 2
At that time, the assertion switch SW2 on the housing information board 2 side is on fire.
It is assumed that it is operated by the resident of the dwelling unit. Then,
The photocoupler light emitting section 22a is activated, and the corresponding light is received.
The part 22b is set to the ON state. Thereby, the repeater 6
Signal paths D and E that connect the housing and the home information board 2 are loop paths
And the true signal is supplied to the receiver 7. Also control
The output of the assertion switch SW2 is also supplied to the section 20, and
Take the same operation as the relay section L 3 closed, speaker S
A voice message for true information is output from P2 and SP3.
It

Operation on the side of the receiver 7 and the repeater 6 The receiver 7 which has received the true information signal via the repeater 6 operates the photocoupler light emitting section 15a of each repeater 6 in the alarm section to receive the light receiving section 15b. Set to ON state. Each repeater 6 in the alarm category sends a true information signal from the terminal T6 to the housing information panel 2 via the signal path L2. It should be noted that the repeater 6 of the alarm category mentioned here refers to the repeater 6 arranged on the fire floor on which the fire unit is located and on the floor directly above the fire floor. Also,
In the relay device 6, the flicker circuit 14 is driven under the true information state, and the alarm lamp 5a provided in the outdoor display device 5 is displayed blinking. In the housing information panel 2 that has received the "Shinho" in this way, the control unit 20 supplies a fire alarm signal to the amplifying unit 21 and outputs a voice message for the true message, "It is a fire. It is a fire. Please make sure you are safe before you evacuate. "

(B) When the assertion switch SW2 is not operated (operation on the repeater 6 side) For example, when the fire source dwelling unit is absent or the fire rotates quickly, and the resident leaves the dwelling unit without operating the assertion switch SW2. , Since the switch SW2 is not operated, "true news"
Is not issued and remains in the "first report" state.
Therefore, in order to avoid such inconvenience, the repeater 6 side
It works as follows.

That is, when the receiving circuit 10 receives the alarm signal from the fire detector 1, the timer circuit 11 starts clocking and automatically generates a true alarm signal after a lapse of a predetermined time (for example, 3 minutes). Then, the signal is supplied to the receiving circuit 10 and the receiver 7. The receiving circuit 10 receiving the true information signal outputs a mode signal indicating the true information state to the audio circuit 12 in the next stage without driving the photocoupler light emitting unit 10a. Then, in the voice circuit 12, as a voice message in the true report mode, a fire alarm is emitted from the speaker SP1 such as "Fire. It is a fire. A fire has occurred in ○○. Please check the safety and evacuate." To do. In the voice message, the "floor" or "dwelling unit number" where the fire occurred is uttered in the "○○" part.

As described above, in the present system, even if the assertion switch SW2 is not operated on the housing information board 2 side, the "true information" can be automatically issued after a predetermined time has elapsed from the time when the first information is generated. In that case, It is possible to give a voice notification of a fire even from the repeater 6. The timer circuit 11
The receiver 7 which has received the true information signal from the
Similar to the case when 2 was operated, the fire floor with the Hinomoto dwelling unit,
A true signal is sent to the house information board 2 to the repeater 6 arranged immediately above the fire floor.

(3) Operation When Abnormality Occurs in Housing Information Board 2 Operation on Housing Information Board 2 Next, it is assumed that drive power is not supplied to the housing information board 2 due to a power failure or the like. Then, the photocoupler light-emitting portion 23a does not emit light, which causes the light-receiving portion 23b.
Is turned off, and the terminal T of the repeater 6 is connected via the signal path K.
An abnormality such as a power failure in the housing information board 2 is notified to 3. In addition, the relay drive circuit built in the control unit 20 due to a power failure causes the relay sections L ₁ and L ₂ to be in the “OFF” side and L ₃
To the "ON" side.

Operation on the Repeater 6 Side When the abnormality of the home information board 2 is notified to the repeater 6 side, the repeater 6 switches the audio signal output path from the speaker SP1 to the signal path BU side, and the transformer TR. An audio signal is supplied to the home information panel 2 via the signal path KP connected thereto. As a result, the audio signal output from the audio circuit 12 passes through the signal path KP that is transformer-coupled from the signal path BU, and then passes through the relay sections L ₁ , L ₂ , and L ₃ to the speaker SP2.
Connected to SP3. Therefore, even if an abnormality occurs in the home information panel 2, it is possible to give a voice alarm to the home information panel 2 and the outdoor display 5 from the repeater 6 side.

(4) Inspection Operation Next, when inspecting the fire detector 1, the inspection switch SW1 arranged on the operation panel of the repeater 6 is operated.
When the switch SW1 is operated, the inspection circuit 13 supplies the inspection signals Qa and Qb to the fire detector 1 while driving the built-in photocoupler light emitting portion 13a. When the photocoupler light emitting unit 13a is driven, the light emitting unit 1
The light receiving portion 13b corresponding to 3a is turned on, and the terminal T
4 informs the housing information panel 2 connected via the signal path T that the test mode is in effect.

When the check switch SW1 is operated, the check circuit 13 indicates that the receiving circuit 10 is in the test mode.
Instructed by the side. When the receiving circuit 10 receives the alarm signal output from the fire detector 1 in response to the inspection signals Qa and Qb, the voice circuit 12 gives the inspection result "normal" according to the instruction of the receiving circuit 10. Notify by voice. If the fire detector 1 does not output the alarm signal in response to the inspection signals Qa and Qb, the voice circuit 12 utters a voice message "abnormal" to notify the abnormality of the fire detector 1. . Thus, according to the inspection operation of this system, the fire detector 1 can be operated only by operating the inspection switch SW1.
Since normality / abnormality of is notified by voice, extremely simple inspection is realized. Note that the relay device 6 is provided outside the room and is provided, for example, on the back side of the nameplate to prevent mischief, and is provided at a position where only an inspector can operate it. Also, the inspection result is notified by voice, and the repeater 6 uses a two-color LED,
The display may be normal (green) / abnormal (red). Further, in a system in which a plurality of sensors are sequentially inspected, a voice message such as "first sensor normal" or "Nth sensor normal" may be output.

As described above, according to this embodiment, the speakers SP2 and SP3 built in the house information panel 2 and the outdoor display 5 arranged in each dwelling unit can be used for fire alarms. There is no need to lay a dedicated fire alarm bell in the dwelling unit, and this will not increase the cost,
It is possible to report a fire for each dwelling unit. Further, when the housing information board 2 does not function due to a power failure or the like, the output of the audio circuit 12 is supplied to the speakers SP2 and SP3 built in the housing information board 2 and the outdoor display 5,
Since the fire alarm can be issued from these speakers SP2 and SP3, the fire alarm function will not be lost even in the event of a power failure. Further, since the normality / abnormality of the fire detector 1 is notified by voice only by operating the inspection switch SW1, an extremely simple inspection operation is realized.

In this embodiment, the fire alarm or fire alarm is issued by a voice message. However, the present invention is not limited to this. For example, a siren sound or a bell sound may be generated alternately with the voice message. You can
Further, in this embodiment, the voice circuit 12 and the inspection circuit 13 are provided on the repeater 6 side, but instead of this, for example, they may be built in the outdoor display 5, and these variations are possible. Needless to say, the gist of the present invention can be realized. Furthermore, the voice circuit may output voice only during inspection or when an abnormality occurs in the home information panel 2.
