In the fire alarm system for an apartment house shown in this figure, a self-ignition warning general board 2 is provided between a residential building receiver 1 and a repeater 3, and the self-fire warning general board 2 is provided for each warning area, for example, on each floor. It is arranged for each. Relays BF, BN, a speaker 7 and the like are provided on the self-ignition bulletin board 2, and the relays BF, BN are operated by the district acoustic control signal E6 from the residential wing receiver 1. FIG. 4 is a circuit diagram showing the periphery of the relays BF and BN of the self-ignition bulletin board 2. In this figure, when the relay BN is activated by the district acoustic control signal E6, the relay contacts bn ₁ and bn ₂ are NO.
The voice alarm signal E7 from the residential receiver 1 is supplied to the speaker 7 of the self-ignition bulletin board 2 by switching to the side. Also, in the same way, relay B by the district sound control signal E6.
When F is activated, the relay contacts bf ₁ and bf ₂ are switched to the NO side, and the voice alarm signal E7 from the residential building receiver 1 is transmitted via the self-ignition bulletin board 2 to the outdoor display 5 and the shared speaker 6
Will be supplied to the dwelling unit receiver 4 via the self-fired alarm general board 2 and the repeater 3.

Returning to FIG. 3, the district sound control signal E6 is supplied to the self-fired alarm general control board 2 and is transmitted from the self-fired alarm general control board 2 to the dwelling unit receiver 4 and the outdoor display 5 via the repeater 3. Supplied. Self-recovery type fire detectors 10 and 10 are connected in parallel to the repeater 3 via detector lines 11a and 11b. By detecting the sensor line 11a,
A reporting current is passed between 11b. When this alarming current is output to the repeater 3, the reception relay L of the reception circuit 12 in the repeater 3 is activated, the relay contact 1 is closed, and a sensor activation signal (hereinafter, simply referred to as “activation signal”). ) E1 is supplied to the dwell unit receiver 4. At the same time as the operation of the reception relay L, the holding relay M of the holding relay circuit 13 is also actuated to close the relay contacts m ₁ and m _{2 so} that the output permission state of the fire signal and the holding permission state of the actuation signal E1 are changed. Produced.

In the dwelling unit receiver 4, when the actuating signal E1 is input from the repeater 3, the receiving relay R of the receiving circuit 14 is actuated, and when the actuating signal E1 is continuously actuated for, for example, 10 seconds, the receiving state of the actuating signal E1 is received. Is held and holding relay H
Is actuated, the relay contact h is closed, and the holding signal E2 that is at the “L” level is output to the repeater 3. When the holding signal E2 via a relay contact f ₂ is input, the repeater 3
Then, the holding circuit 17 operates and holds the holding relay M of the holding relay circuit 13 so as not to be deactivated even if the fire detector 10 is restored. At the same time, the holding circuit 17 changes the supply voltage to the outdoor display 5 from + 12V to + 24V which is the power / fire signal E8 to display a fire.
The detection circuit 19 of the outdoor display 5 detects + 24V which is the power / fire signal E8 and blinks the indicator lamp 20. The dwelling unit receiver 4 activates its own voice synthesizer 27 by inputting the actuation signal E1 from the repeater 3, synthesizes a message indicating the actuation of the fire detector 10, and amplifies it with the amplifier 28, and then relays it. Output from the speaker 26 via the contact dc.

Further, the dwelling unit receiver 4 monitors for a predetermined time within a range of 2 to 5 minutes from the time when the operation signal E1 is sent from the repeater 3. That is, when the operation signal E1 is input, the reception relay R is activated, and at the same time, the delay timer 15 in which the delay time T1 of 2 to 5 minutes which is the fire confirmation time is set is activated. It is determined whether the recovery switch (not shown) has been operated for 2 to 5 minutes, and if the recovery switch is not operated during this period, the relay contact t ₁ opens and the voltage signal is interrupted. Then, the fire confirmation signal E3 is output to the repeater 3.
The dwelling unit receiver 4 outputs the fire confirmation signal E3 when
The voice synthesizer 27 synthesizes a message indicating a fire,
After being amplified by the amplifier 28, it is output from the speaker 26 via the relay contact dc. When the voltage confirmation signal is cut off by the fire confirmation signal E3 being output from the dwelling unit receiver 4,
In the repeater 3, the output of the photocoupler 21 changes from the “L” level to the “H” level, the inverter 22 inverts the output to the “L” level, and the relay contact m ₂ is already closed at this point. Since it is in the output permissible state, a current flows through the fire confirmation transfer relay S to operate. When the fire confirmation transfer relay S is activated, the relay contact s ₁ is closed and the fire signal E4 that is at the “L” level is output to the residential building receiver 1 via the fire alarm signal line 23. In addition, relay contact s
₂ is closed, and the reception state of the confirmation signal E5 from the residential receiver 1 is created.

In the receiver 1 for the residential building, the fire representative display and the district display are performed by receiving the fire signal E4 from the repeater 3 via the fire alarm signal line 23. At the same time, the fire representative relay (not shown) operates and the corresponding district relay (not shown) also operates. The operation of the fire representative relay closes the relay contact fa, and the confirmation signal E5 is output to the repeater 3 via the confirmation signal line 24. When the confirmation signal E5 is output from the receiver 1 for a residential building, the relay F operates in the repeater 3 to close the relay contact f ₁ for the residential unit by the series circuit with the relay contact m ₁ already closed. The output state of the operation signal E1 to the receiver 4 is continuously held.
Further, the opening of the relay contact f ₂ disconnects the input of the holding signal E2 from the dwelling unit receiver 4, and in the future, the holding operation of the holding circuit 17 of the repeater 3 is performed by the confirmation signal E5 from the dwelling unit receiver 1. Done. That is, the dwelling unit receiver 4 detects that the relay contact f ₂ is opened when the input from the photocoupler 36 disappears, and stops self-holding. Therefore, the dwelling unit receiver 4 will receive the operation signal E from the repeater 3 in the future.
The alarm operation is performed only while 1 is output.

Further, in the residential building receiver 1, by operating a district relay (not shown), the district acoustic control signal E6 is transmitted to the neighboring dwelling units, specifically, the dwelling units on the floor where the fire occurred and the floor immediately above it.
Is output. The district acoustic control signal E6 for the dwelling units on the fire-occurring floor and the floor immediately above it is given to the dwelling unit receiver 4 and the outdoor display unit 5. At this time, in the neighboring dwelling unit receivers 4 other than the fire dwelling unit, The phototransistor of the photocoupler 25 is turned on by the district sound control signal E6, the relay B is activated, the relay DC is deactivated by opening the relay contact b, and the relay contact dc is activated by the voice alarm signal line 9 ₁
The speaker 26 is switched to the side and the voice alarm signal E7 can be input from the voice alarm signal line 9 ₁ . Further, in the outdoor display 5 of the fire house, the detection circuit 19

By the way, there is a revision of the standards of the Fire Service Law in recent years, and in an automatic fire alarm system for an apartment house, considering the case where the resident is absent, the fire detector can be remote from outside the residence. It was specified that an operation test could be performed.
In the conventional fire alarm system for an apartment house as shown in FIG. 3, when it is attempted to apply the remote operation test of the fire detector from outside the dwelling unit, the relay 3 installed outside the dwelling unit has a fire detection function. By connecting an external tester for performing a remote operation test on the device 10, the sensor lines 11a and 11b are switched to the external tester side, and in that state, the fire detector 10
It is conceivable to send a test signal to each of the fire detectors 10 to test the operation of the fire detectors 10 one by one, and to confirm the test results with an external tester. In addition, at the time of the remote operation test of the fire detector 10, not only the operation test of the fire detector 10 but also a comprehensive inspection (dwelling unit inspection) of the entire dwelling unit including an interlocking test with the receiver 1 for residential building It is desired to do.

However, when such a dwelling unit inspection is applied to the conventional fire alarm system for an apartment house as shown in FIG. 3, a remote operation test of the fire detector 10 by an external tester is performed to make the dwelling unit When the receiver 1 for fire receives the fire signal E4 from the repeater 3, the district acoustic control signal E6 and the voice warning signal E7 are sent to the dwelling units on the fire floor and the floor immediately above the fire floor. Speaker 7 of general board 2, speaker 6 for common use, fire 2 on the fire floor and on the floor directly above it
6. The voice alarm signal E7 output from the residential receiver 1 is output from the speaker 29 of the outdoor display unit 5 of the inspection dwelling unit, which causes a problem for the occupants at home. .

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a fire alarm system for a shared house, which can inspect a dwelling unit and a common area without causing undesired shaking of a resident. Has an aim.

[0015]

In order to achieve the above object, the fire alarm system for an apartment house according to the invention of claim 1 outputs a district sound control signal and a voice alarm signal when a fire signal is received. The ward receiver and the sound alarm signal output from the residential receiver are distributed to the residential receiver, the outdoor display and the speaker in the common area, and the district acoustic control is performed on the line that passes the district acoustic control signal. A fire alarm system for an apartment house, comprising a self-ignition bulletin board in which a relay operated by a signal is provided, and a relay contact of the relay is provided on a line through which a voice warning signal is passed. The general panel includes a first switch means for distributing the audio alarm signal output from the residential building receiver by bypassing the relay contact to the residential unit receiver and an outdoor display, and the residential building reception. Sound output from the machine Characterized by comprising a second switch means for distributing an alarm signal to said common unit speaker.

According to the above construction, when the fire alarm signal is received at normal times, when the district acoustic control signal and the voice alarm signal are output from the receiver for residential area, the self-fire alarm is issued by the district acoustic control signal. The relay installed on the line through which the local sound control signal of the general board passes is activated and the relay contact closes.
As a result, a line for passing a voice alarm signal is connected in the self-fire alarm integrated board, and the voice alarm signal from the residential ward receiver flows to the residential unit receiver, the outdoor display, and the shared speaker. Also,
If you set the receiver for residential building so that only a voice alarm signal is output and a district acoustic control signal is not output when a fire signal is received during inspection (when the "maintenance inspection mode" described below is set), Even if the receiver for residential building receives a fire signal, it does not output the district acoustic control signal, so the relay of the self-ignition bulletin board does not operate, the relay contact remains open, and the voice alarm signal is Does not flow to the receiver, outdoor display, and speaker in the common area.

When the dwell unit is inspected, by turning on the first switch means, the relay contact of the self-ignition bulletin board is bypassed, and a voice alarm signal is sent via the first switch means to the dwell unit receiver. And to the outdoor display. Here, during the remote test of the fire detector by the external tester, the speaker of the outdoor display of the inspection dwelling unit is connected to the audio alarm signal line, so the audio alarm signal of the outdoor display of the inspection dwelling unit is connected. It flows into a speaker, and a voice alarm signal is output from the speaker and sounds. In addition, by turning on the second switch means when inspecting the common area, the relay contact of the self-ignition bulletin board is bypassed, and a voice alarm signal is sent to the common area speaker via the second switch means. Then, a voice alarm signal is output from the speaker and sounds. In this way, by selecting and operating the first switch means or the second switch means on the self-fired alarm general panel according to the inspection content, the speaker from which the voice alarm signal is output can be selected, which is unnecessary for the person at home. It is possible to inform and check the inspection results of the dwelling units and common areas without causing any upset.

In the fire alarm system for an apartment house according to the second aspect of the present invention, when a fire signal is received at the time of reporting, a district acoustic control signal and a voice alarm signal are output to a neighboring dwelling unit, and at the time of inspection. , When performing a remote operation test of a receiver for a residential building that outputs only a voice alarm signal when a fire signal is received in the maintenance inspection mode and a fire sensor inside the house from outside the house An external tester that outputs a test-in-progress signal by a start operation, and an outdoor display that enables the voice alarm signal to be input to its own speaker when receiving a district acoustic control signal in the test-in-progress signal or a fire detection state,
When receiving the operation signal indicating the operation of the fire detector, the self-sound source causes its own speaker to ring, and in the state where the operation signal is not received, the district acoustic control signal output from the residential receiver When receiving, the sounding alarm signal output from the receiver for residential building makes its own speaker ring, and when receiving the test-in-progress signal from the external tester, the test-in-progress signal is output to the outdoor display, and Shared with a receiver for a residential unit that does not activate its own sound source when it receives an operation signal while receiving a signal during a test, and sounds when receiving an audio alarm signal output from the receiver for a residential building Part speaker,
Distributing the audio alarm signal output from the residential receiver to the residential receiver, the outdoor display and the shared speaker,
A joint equipped with a self-fired alarm board that has a relay that operates according to the district sound control signal on the line that passes the district sound control signal, and a relay contact of the relay that is provided on the line that passes the voice alarm signal. A fire alarm system for a house, wherein the self-fire alarm general panel distributes a voice alarm signal output from the receiver for a residential building by bypassing the relay contact to the receiver for a residential unit and an outdoor display. And a second switch means for distributing the voice alarm signal output from the residential receiver to the common speaker.

According to this structure, in normal times, the receiver for a residential building outputs a district acoustic control signal and a voice alarm signal by receiving a fire signal, and the district acoustic control signal outputs the district acoustic control signal. A relay provided on the line through which the acoustic control signal is passed is activated to close the relay contact. As a result, the line for passing the voice alarm signal is connected in the self-warning information board, and the voice alarm signal from the receiver for residential building flows to the receiver for residential unit, the outdoor display and the speaker in the common area. In this case, the dwelling unit receiver of the fire dwelling unit receives an actuation signal indicating the actuation of the fire detector, and thus causes its own sound source to ring its own speaker. On the other hand, the dwelling unit receiver of the dwelling unit adjacent to the fire dwelling unit does not receive the operation signal, and therefore its own speaker is switched by the district sound control signal and sounds by the sound alarm signal from the dwelling unit receiver. The speaker on the outdoor display of the fire dwelling unit is switched by the district sound control signal and sounds by the voice alarm signal from the receiver for the residential building. The common speaker on the fire floor and the floor directly above it will be activated by a voice alarm signal from the residential receiver.

On the other hand, at the time of inspection, the residential building receiver is set to a maintenance / inspection mode in which only a voice alarm signal is output when a fire signal is received and a district acoustic control signal is not output.
Even if only the voice alarm signal is output from the receiver for the residential building in response to the fire signal, the relay on the line that passes the district acoustic control signal of the self-ignition bulletin board does not operate, and on the line that passes the voice alarm signal. Since the relay contact provided is still open, the voice alarm signal does not flow to any of the dwelling unit receiver, the outdoor display and the common speaker. However, by turning on the first switch means at the time of inspecting the dwelling unit, the relay contact of the self-ignition bulletin board is bypassed by this first switch means, and therefore, for the residential building via the voice alarm signal line. The receiver is connected to the receiver for the dwelling unit and the outdoor display, and the audio alarm signal from the receiver for the dwelling flows to the receiver for the dwelling unit and the outdoor display. At this time, the receiver for the dwelling unit of the inspection dwelling unit receives the signal during the test from the external tester, so even if it receives the operation signal indicating the operation of the fire detector, it will not start its own sound source and the speaker Does not ring.

In the outdoor display of the inspection dwelling unit, since the speaker for the dwelling unit receives the signal under test from the dwelling unit receiver and connects its own speaker to the voice alarm signal line, the voice alarm signal from the receiver for the dwelling unit The self speaker sounds. Since the dwelling unit receiver of the dwelling unit adjacent to the inspection dwelling unit receives neither the test signal, the operation signal, nor the district sound control signal, it does not ring its own speaker. That is, at the time of inspecting a dwelling unit, when the fire alarm signal is output from the dwelling unit receiver and the first switch means is turned on, the fire detector, the dwelling unit receiver, and the dwelling unit If all of the receiver for fire alarm, general panel for fire and fire alarm, outdoor display and voice alarm signal line are normal, a voice alarm signal is output from the speaker of the outdoor display of the inspection dwelling unit and sounds.

When the common area is inspected, the second switch means is turned on so that the second switch means bypasses the relay contacts of the self-ignition bulletin board, and the voice alarm signal line is used for the residential building. If the receiver and the shared speaker are connected, and if all of the fire detector, the receiver for the residential building, the fire alarm board, the shared speaker and the voice alarm signal line are normal, the shared speaker A voice alarm signal is output from
Ring. In this way, by selecting and operating the first switch means or the second switch means on the self-fired alarm general panel according to the inspection content, the speaker from which the voice alarm signal is output can be selected, which is unnecessary for the person at home. It is possible to inform and check the inspection results of the dwelling units and common areas without causing any upset.

(II) Operation of Fire Alarm System for Apartment House The operation of the fire alarm system for apartment house of the present embodiment will be described below. (A) Normal time When receiving a fire signal E4 from the repeater 50 during a normal fire, the residential building receiver 60 outputs a district acoustic control signal E6 and a voice warning signal E7 to the fire floor and the floor immediately above. When the district acoustic control signal E6 is output from the receiver 60 for a residential building, the relays BF and BN provided in the line through which the district acoustic control signal E6 of the self-ignition bulletin board 90 passes are activated and the respective relay contact points are activated. bf and bn are closed. When the relay contact bn is closed, the speaker 7 of the self-ignition bulletin board 90 is connected to the voice alarm signal line 9, and the voice alarm signal E from the receiver 60 for residential building is connected.
7 is output from the speaker 7 and sounds.

When the relay contact bf is closed, the line for passing the voice alarm signal E7 is connected in the self-ignition bulletin board 90, and the voice alarm signal E7 from the residential ridge receiver 60 is transmitted to the residential unit receiver 7.
0 to the outdoor display 80 and the shared speaker 6. In this case, since the dwelling unit receiver 70 of the fire-fired dwelling unit receives the actuation signal E1 indicating the actuation of the fire detector 10 from the repeater 50, it activates its own voice synthesizer 27 to activate the fire detector 10. The message indicating the operation is synthesized, amplified by the amplifier 28, and then output from the speaker 26 via the relay contact dc. When the fire confirmation signal E3 is output, the voice synthesizing unit 27 is activated to synthesize a message indicating that a fire has occurred, and the message is output from the speaker 26. On the other hand, the receiver 70 for each dwelling unit of each dwelling unit on the fire floor and the floor immediately above it excluding the fire unit
In this case, since the operation signal E1 is not received, the relay contact r remains closed. Therefore, the phototransistor of the photocoupler 25 is turned on by the district acoustic control signal E6 from the receiver for residential building 60 to turn on the relay B. There actuated, the relay DC by opening the relay contact b is deactivated, the relay contacts dc is connected is switched speaker 26 to sound the alarm signal line 9 ₁ side, the audio alarm from Houses receiver 60 The signal E7 is output from the speaker 26 and sounds. Further, in the outdoor display 80 of the fire dwelling unit, when the district acoustic control signal E6 is supplied while the detection circuit 19 detects the fire signal E8 from the repeater 50, the relay J operates. The relay contacts j ₁ and j ₂ are switched, the speaker 29 is connected to the voice alarm signal line 9 ₁ , and the voice alarm signal E7 from the residential receiver 60 is output from the speaker 29 and sounds.

(B) At the time of inspecting the dwelling unit (at the time of remote operation test of the fire detector 10 by the external tester 40) At the time of inspecting the dwelling unit, first turn on the district sound stop switch 63 of the dwelling receiver 60 to turn on the fire reception control circuit. 62 is set to the district sound stop mode, and the maintenance mode switch 67 is turned on to set the voice alarm unit 66 to the maintenance mode (hereinafter, the district sound stop mode and the maintenance mode are simply referred to as maintenance inspection mode). Further, the first manual switch 91 of the self-fired alarm general board 90 on the floor to be inspected is turned on to bypass the relay contact bf.

After setting the receiver 60 for the residential building in the maintenance / inspection mode and turning on the first manual switch 91 of the self-ignition bulletin board 90 in this way, the external tester 4
0 is connected to the repeater 40 to start the remote operation test of the fire detector 10. First, the external tester 40 sends a signal E9 during the test.
Is output, the relay K operates in the repeater 50, the contacts k ₁ and k ₂ are switched, and the sensor lines 11 a and 1
1b is switched to the external tester 40 side, and the in-test signal E9 is output to the dwelling unit receiver 70. Dwelling unit receiver 7
When 0 receives the in-test signal E9, the alarm operation by itself is prohibited. In this state, the external tester 40 outputs the test signal Q to the fire detector 10 through the test signal line 11c, and confirms the test state from the pseudo alarm state of the fire detector 10 at that time. The first fire detector 1 that received the test signal Q
0 gives a pseudo alarm and outputs a test signal Q to the fire detector 10 in the next stage. When the test of the fire detector 10 ends normally, the external tester 40 outputs an OK signal to the repeater 50. In the repeater 50, the relay OK operates by receiving the OK signal, and the contact signal ok is closed to output the operation signal E1 to the dwelling unit receiver 70. The dwelling unit receiver 70 outputs the fire confirmation signal E3 to the relay device 50 immediately after receiving the operation signal E1 because the activation of the delay timer 15 is prohibited by receiving the in-test signal E9. Upon receipt of the fire confirmation signal E3, the repeater 50 immediately outputs the fire signal E4 to the residential building receiver 1. A fire signal E4 is output from the repeater 50, and the residential ridge receiver 60 that has received the fire signal E4 outputs only the voice alarm signal E7 because the maintenance / inspection mode is set.

In the self-fire alarm board 90, when the first manual switch 91 is turned on and the contacts 91b and 91c are closed, the relay contact bf is bypassed, and the residential building reception is performed via the voice alarm signal line 9 _1. Machine 60 and receiver 7 for dwelling units
0 and the outdoor display 80 are connected, the voice alarm signal E7 from the residential ridge receiver 60 flows to the residential receiver 70 and the outdoor display 80. At this time, in the dwelling unit receiver 70 of the inspection dwelling unit, since the alarm operation is prohibited by receiving the signal E9 during the test from the repeater 50, the voice synthesizing unit 27 does not start, and the voice alarm is output from the speaker 26. No output and no sound. In addition, the receiver 70 for each dwelling unit on the floor of the dwelling unit and the dwelling unit on the floor immediately above the dwelling unit excluding the dwelling unit 70
In that case, since the district sound control signal E6 does not come,
The relay B remains inactive, therefore the contact dc is not switched and the speaker 26 does not output the voice alarm signal E7.

On the other hand, in the case of only the outdoor display 80 of the inspection dwelling unit, the in-test signal E is sent from the dwelling unit receiver 70 of the inspection dwelling unit.
Since relay J is operating in response to 9, the relay contact j
_{Since 1} is closed and the relay contact j ₂ is switched to the voice alarm signal line 9 ₁ side, when the voice alarm signal E7 is output from the residential receiver 60, the speaker of the outdoor display 80 is displayed. A voice alarm signal E7 is output from 29 and sounds. On the other hand, in the outdoor unit 80 of the dwelling unit on the floor of the dwelling unit other than the dwelling unit for inspection and the dwelling unit on the floor immediately above, the relay J does not receive the signal E9 during the test from the receiver 70 for dwelling unit. Since the relay contact j ₁ is in the open state and the relay contact j ₂ is connected to the internal circuit (doorphone) side, the outdoor display is displayed even if the voice alarm signal E7 is output from the receiver 60 for the residential building. The voice alarm signal E7 is not output from the speaker 29 of the container 80 and does not ring.

As described above, by setting the residential building receiver 60 in the maintenance / inspection mode and turning on the first manual switch 91 of the self-ignition bulletin board 90, the fire detector 10 by the external tester 40 is turned on. When the fire test signal E4 is output from the repeater 50 and the sound alarm signal E7 is normally output from the residential building receiver 60 after the operation test of No. 3 is completed normally, only the speaker 29 of the outdoor display 80 of the inspection dwelling unit A voice warning signal E7 is output and sounds. The inspector can confirm that the results of the dwelling unit inspection including the operation test of the fire detector 10 and the comprehensive inspection of the system are normal by listening to the voice alarm from the speaker 29. By turning on the second manual switch 92 while the first manual switch 91 is turned on, the shared speaker 6 is also connected to the residential ridge receiver 60 via the voice alarm signal line 9, Building receiver 6
A voice alarm signal E7 from 0 is also output from the shared speaker 6 and sounds. By doing so, the common-use speaker 6 can be inspected at the time of inspecting the dwelling unit.

(C) At the time of inspecting the common area To inspect the common area including the speaker 6 in the common area, the receiver 60 for the residential building is set in the maintenance / inspection mode, and the self-ignition bulletin board 90
If both the first manual switch 91 and the second manual switch 92 are turned on, the fire detector 10 adjacent to the shared speaker 6 to be tested is forcibly operated by using a tester such as a heating tester. good. When the fire detector 10 in the common area is forcibly activated, the residential wing receiver 60 outputs a voice alarm signal E7 toward the floor where the fire detector 10 is installed and the floor immediately above. If there is no obstacle in the receiver 60 for the residential building, the self-fired fire alarm board 90, the shared speaker 6 and the voice alarm signal line 9 between them, the voice alarm signal E7 is the contact points 91b and 91c of the first manual switch 91. It passes through the contact of the second manual switch 92 and is output from the shared speaker 6 and sounds. The inspector can confirm that the result of the inspection of the common area including the common area speaker 6 and the comprehensive inspection of the system is normal by hearing the voice alarm from the common area speaker 6. In this case, although the voice alarm signal E7 passes through the contacts 91b and 91c of the first manual switch 91 and also flows to the dwelling unit receiver 70 and the outdoor display 80, the district sound control signal E6 is output. Since the relay units B and J are not operated and the dwelling unit is not inspected, the voice alarm signal E7 is not output from the speakers 26 and 29.

As described above, in this embodiment, the sound alarm signal E7 is output only from the speaker 29 of the outdoor display unit 80 of the inspected dwelling unit at the time of inspecting the dwelling unit, and from the speaker 6 at the inspecting floor at the time of inspecting the common unit. Only voice warning signal E
Since 7 is output, it is possible to notify the inspector of the inspection result without causing unnecessary sway to the person at home. In the above embodiment, the second manual switch 9
No. 2 does not become effective unless the first manual switch 91 is turned on. However, the connection side of the second manual switch 92 with the first manual switch 91 is set to the self-ignition bulletin board 90.
It is also possible to directly connect to the input side of the voice alarm signal E7 and be effective without turning on the first manual switch 91. In this case, the second switch means according to claims 1 and 2 corresponds to the second manual switch 92.

Further, in the above embodiment, both the first manual switch 91 and the second manual switch 92 are lock type, but both may be non-lock type. However,
The first manual switch 91 cannot be inspected unless the inspector inspects the dwelling unit by himself without using the lock type. Of course, when two or more people are inspecting, the non-locking type may be used because only one person needs to operate the self-ignition bulletin board 90. Regarding the second manual switch 92, since the common speaker 6 and the fire detector 10 of the common part are generally located in the vicinity of the self-ignition bulletin board 90, the second manual switch 92 is used.
While pressing, use the heating tester etc.
Since it is possible to forcibly activate the fire detector 10 adjacent to the non-locking type, a non-locking type can be used. On the contrary, by using the non-lock type, there is an advantage that it is possible to prevent forgetting to return the switch.

In the above embodiment, the external tester 4 is used.
Although the remote operation test of the fire detector 10 by 0 was performed by using the test signal line 11c to sequentially send the test signals,
The test signal line 11c is eliminated and the sensor lines 11a and 11b
Alternatively, the fire detectors 10 may be addressed one by one to issue a test report.
