(1) Operation when the fire detector 1 operates The operation of 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 repeater 6 The receiving circuit 10 receives this. Then, the circuit 10 drives the photocoupler light emitting unit 10a-1 to turn on the corresponding photocoupler light receiving unit 10b-1. As a result, the "first report" is given to the signal path L1 connecting the terminal T1 of the repeater 6 and the terminal R1 of the house information board 2. When receiving the alarm signal, the receiving circuit 10 supplies an "H" level signal representing the operation of the sensor to one input end of the AND circuit 17, but in this case, the housing information panel 2 is not in an abnormal state. The AND circuit 17 does not generate a true signal.

Operation on the side of the housing information board 2 The housing information board 2 which has received the "first report" via the signal path L1
Then, the "first report mode" is entered, and the control unit 20 reproduces and outputs a voice message "Fire detector has activated. Please check." To the voice synthesis circuit 20a. As a result, the above-described fire notification message is uttered from the internal speaker SP1 of the house information board 2 and the speaker SP3 of the outdoor display device 5.

(2) Operation when a fire is confirmed (a) When the indeterminate switch SW2 is operated Operation on the housing information board 2 side When the "first report" is issued in this manner, the housing information board Assume that the assertion switch SW2 on the second side is operated by the resident of the fire unit. Then, the photocoupler light emitting unit 2
2a is activated, and the light receiving portion 22b corresponding thereto is set to the ON state. As a result, the signal paths D and E connecting the repeater 6 and the housing information panel 2 form a loop path, and the receiver 7
To the true information signal.

Operation of Receiver 7 and Repeater 6 Side The receiver 7 which receives the true signal via the repeater 6 activates the photocoupler light emitting section 10a-2 of each repeater 6 of the alarm section, The light receiving unit 10b-2 corresponding to is set to the ON state. Then, each relay 6 in the alarm section sends a true signal from the terminal T2 to the home information panel 2 via the signal path L2. In addition, the repeater 6 of the alarm category mentioned here is
It refers to the repeater 6 arranged on the fire floor where the fire unit is located and on the floor directly above the fire floor. Further, in the repeater 6 of the dwelling unit in which the fire has occurred, the flicker circuit 14 is driven under the true information state, and the alarm lamp 5a arranged on the outdoor display 5 is displayed in a blinking manner.

Operation of Housing Information Board 2 Next, in the housing information board 2 which has received the "Shinho", the "Shinho mode" is set, and the control unit 20 instructs the voice synthesis circuit 20a to "fire. There is a fire." A fire occurred in ○ (Housing number, etc .. Please make sure you are safe before you evacuate. " As a result, the above-mentioned fire alarm message is uttered from the internal speaker SP1 of the house information board 2 and the speaker SP2 of the outdoor display 5.

(B) When the assertion switch SW2 is not operated (operation on the repeater 6 side) For example, when the fire in the fire source dwelling unit is fast and the resident has left the dwelling unit without operating the assertion switch SW2,
When there is no resident of the fire unit, the switch SW
Since "2" is not operated, "Shinho" is not emitted and "1st
It remains in the "report" state. Therefore, in order to avoid such an inconvenience, the repeater 6 operates as follows.
That is, when the receiving circuit 10 receives the warning signal from the fire detector 1, the timer circuit 11 starts clocking, and after a lapse of a predetermined time (for example, 3 minutes), a true notification signal is automatically generated and received. Supply to machine 7. Receiving this true signal, the receiver 7 issues true information to the repeater 6 arranged on the fire floor and the floor immediately above it. In this way, in this system, even if the assertion switch SW2 is not operated on the housing information board 2 side, it is possible to automatically issue the "true report" after a predetermined time has elapsed from the time point when the first report was issued.

(3) Operation when abnormality occurs in the housing information board 2 Operation on the housing information board 2 side Next, when the first report occurs, the driving power is not supplied to the housing information board 2 due to a power failure or the like. Suppose that Then, the photocoupler light emitting unit 23a does not emit light and the corresponding light receiving unit 23b is turned off, so that the terminal T5 of the repeater 6 connected via the signal path K becomes the "H" level.

When the operation terminal T5 on the repeater 6 side becomes the "H" level, the abnormality receiving circuit 15 detects the abnormality of the housing information panel 2 and outputs the "H" level signal to the other input terminal of the AND circuit 17. Supply. In this state, when the receiving circuit 10 receives the alarm signal from the fire detector 1, the receiving circuit 10 outputs an AND circuit 17 to the alarm signal.
An "H" level signal is supplied to one of the input terminals, and the true signal is output from the AND circuit 17. Therefore, according to the present system, even if the dwelling unit information panel 2 goes down due to a power failure or the like and is in an abnormal state, a true signal is immediately generated and supplied to the receiver 7 side after the alarm signal is generated. Fire alarm is possible.

(4) Inspection operation Operation on the outdoor display 5 and relay 6 side At the time of inspection, the inspection switch S arranged on the outdoor display 5
W1 is operated. When the switch SW1 is operated, the inspection circuit 13 supplies the inspection signal Q to the fire detector 1 while driving the built-in photocoupler light emitting portion 13a. Then, when the photocoupler light emitting portion 13a is driven, the light receiving portion 13b corresponding thereto is turned on, and the terminal T3 is notified to the housing information panel 2 via the signal path T that it is in the test mode.

In the housing information panel 2, when in the test mode, the relay circuit 21a turns on the relay section L ₁ and turns off the relay section L ₂ in response to the instruction from the control unit 20, while the voice synthesis circuit 20a operates. The inspection result "No abnormality. Normal" is played back as a message and this is notified from the outdoor display 5. When the fire detector 1 does not operate in response to the inspection signal Q, the voice synthesizing circuit 20a utters a voice message "It is abnormal" to notify the abnormality of the fire detector 1. As described above, according to the inspection operation of the present system, the normality / abnormality of the fire detector 1 is notified by voice only by operating the inspection switch SW1, so that an extremely simple inspection is realized.

As described above, according to the present embodiment, even if the resident of the dwelling unit where the fire is detected is absent and the assertion switch SW2 is not operated on the housing information board 2 side, a predetermined time has elapsed from the time when the first report occurred. After that, the timer circuit 11 automatically issues "true news", so that it becomes possible to give an instruction of true news generation from the house information panel 2 to the receiver 7 side via the relay 6. Further, even when the dwelling unit information panel 2 is down due to a power failure or the like when a fire is detected, the AND circuit 17 outputs the output of the receiving circuit 10 which receives the alarm signal and the photocoupler light receiving which is turned off according to the power failure Since the true signal is generated by the logical product of the output of the section 23b and the output of the abnormality receiving circuit 15 that detects the abnormality on the housing information panel 2 side, and this is supplied to the receiver 7 side, the fire alarm function It is possible to promptly notify the fire without losing the fire. Further, in this embodiment, since the normality / abnormality of the fire detector 1 is notified by voice only by operating the inspection switch SW1, a very simple inspection can be realized without using an inspection device as in the conventional case. .

In the present embodiment, the fire alarm or fire alarm is issued by a voice message, but the present invention is not limited to this, and for example, a siren sound, a bell sound, etc. may be alternately produced with the voice message. You can
