Description

  The present invention relates to an alarm system.

  Conventionally, in a building such as a hospital or a hotel, when a disaster such as a fire occurs, an acoustic device for detecting the disaster and notifying the people in the building of the occurrence of the disaster is installed. The sound device informs people in the building that a disaster has occurred by sounding an alarm sound. Also, if the scale of the building is large, the building is equipped with emergency broadcast equipment. In the event of a disaster, the emergency broadcast facility works in conjunction with the sounding of the alarm sound by the above-mentioned audio device, and sends an emergency broadcast including guidance for evacuation guidance to a predetermined broadcast area from a speaker installed in a corridor or the like in a building. Urge people in the building to evacuate quickly. For example, when a detector detects that a fire has occurred, the emergency broadcast facility starts an emergency broadcast in which a fire area and a fire floor are directly connected to the fire floor and the floor immediately above. Then, the emergency broadcast facility starts whole-broadcast simultaneously targeting all broadcast areas when a predetermined time has passed after transition to fire broadcast.

  By the way, with the increase of elderly people and progress of social participation of people with disabilities, it is assumed that people in the building where emergency broadcast facilities are installed include deaf people including elderly people with deafness. Ru. Therefore, a hearing impaired person may not be able to respond quickly to a disaster because the emergency broadcast can not be heard when the disaster occurs.

  In order to solve the above problems, an alarm system has been proposed which reports occurrence of a disaster using an emergency broadcasting facility and a light alarm device such as a flash light having high visibility (for example, see Patent Document 1). Since the above-mentioned alarm system gives an alarm (hereinafter referred to as "light alarm") by emitting a flash light in addition to the emergency broadcast in the event of a disaster such as a fire, the alarm system is also effective for deaf people. It can be performed.

In addition, the control device determines that the emergency broadcast facility has shifted from the divided broadcast to the simultaneous broadcast, and determines that the emergency broadcast facility has shifted to the simultaneous broadcast, powers the light alarm devices installed in all alarm areas Supply. Below, the alarm system of an embodiment is explained concretely.

First Embodiment
FIG. 1 is a diagram showing an example of a schematic configuration of the alarm system 1 of the first embodiment.
The alarm system 1 of the first embodiment includes a first timer 51, a second timer 52, and a control unit 53. The first timer 51 counts time when acquiring the regional acoustic control signal supplied from the receiver. The second timer 52 starts clocking when the clocking time of the first timer 51 has reached the first set time. The first set time is set as a time until the emergency broadcast facility 40 shifts from the alert broadcast to the fire broadcast. When the time counted by the second timer 52 has reached the second set time, the control unit 53 determines that the emergency broadcast facility 40 has shifted to simultaneous broadcasting, and performs a light alert simultaneously throughout the entire building. The second set time is set as a time when the emergency broadcast facility 40 transitions from fire broadcast to simultaneous broadcast. However, the second timer 52 starts clocking when acquiring a confirmation signal from the receiver even if the clocked time of the first timer 51 has not reached the first set time.

As shown in FIG. 1, the alarm system 1 of the first embodiment is installed in a building of n (n is an integer) floor, detects occurrence of disaster such as fire and gas leak, and detects occurrence of disaster detected Inform people in the building.
The alarm system 1 includes a plurality of detectors 5 (detectors 5-1 to 5-n), a plurality of light alarm devices 10, a plurality of speakers 20, a receiver 30, an emergency broadcast facility 40, and a light control device 50. The receiver 30 and the light control device 50 described below may be configured as a control device. Moreover, although the alarm system 1 is provided with the some detector 5, the some light alarm apparatus 10, the some speaker 20, the receiver 30, the emergency broadcast installation 40, and the light control apparatus 50, it is not limited to this. For example, the alarm system 1 may include the receiver 30, the emergency broadcast facility 40, and the light control device 50.

The detector 5 is disposed on the ceiling or wall of each floor of the building. Specifically, one or more detectors 5 are disposed on each floor at the legal installation intervals. The detector 5 is connected to the receiver 30 via the detection line 4 (detection lines 4-1 to 4-n).
The detector 5 detects a disaster such as a fire or a gas leak. When the detector 5 detects a disaster such as a fire or a gas leak, the detector 5 outputs a disaster detection signal. In the present embodiment, a case where the detector 5 is a fire sensor for detecting a fire will be described. For example, the detector 5 detects smoke concentration or temperature in a predetermined section, and determines that a fire has occurred when the detected smoke concentration or temperature exceeds a predetermined threshold. Alternatively, the detector 5 includes a sensor element for detecting smoke concentration or temperature inside its own device, and determines that a fire has occurred based on a detection result (for example, an ON signal) of the sensor element. When the detector 5 detects the occurrence of a fire, the detector 5 outputs a fire detection signal (disaster detection signal) indicating the occurrence of a fire to the receiver 30 via the detection line 4. In the present embodiment, when the occurrence of a fire is detected, the detector 5-1 disposed on the first floor outputs a fire detection signal indicating the occurrence of a fire to the receiver 30 via the detection line 4-1. . When the occurrence of a fire is detected, the detector 5-2 disposed on the second floor outputs a fire detection signal indicating the occurrence of a fire to the receiver 30 via the detection line 4-2. That is, when the occurrence of a fire is detected, the detector 5-n disposed on the n-th floor outputs a fire detection signal indicating the occurrence of a fire to the receiver 30 via the detection line 4-n.

The receiver 30 includes terminals B (B _{1 to} B _n ), terminals EA (EA _{1 to} EA _n ), and a terminal EF. The terminals B _{1 to} B _n are connected to the light control device 50 through signal lines 33 respectively. The terminals EA _{1 to} EA _n are connected to the emergency broadcast equipment 40 via the signal lines 31 respectively. The terminal EF is connected to the emergency broadcast facility 40 via the signal line 32. The terminal EF is connected to the light control device 50 via the signal line 34.

The receiver 30 selects a specific terminal B from the terminals B _{1 to} B _n based on the fire detection signal supplied from the detector 5. The receiver 30 outputs a regional acoustic control signal to the light control device 50 from the selected terminal B. The details will be described below. Receiving the fire detection signal supplied from the detector 5, the receiver 30 identifies the floor where the fire has occurred (hereinafter referred to as the "fire occurrence floor"). For example, the receiver 30 determines the fire occurrence floor by determining from which line in the detection line 4 the fire detection signal is obtained. When the fire detection signal is input to the terminal connected to the detection line 4-n, the receiver 30 determines that the fire occurrence floor is the nth floor.
The receiver 30 outputs a regional acoustic control signal from each terminal B corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor. Here, terminals B _{1 to} B _n are terminals corresponding to the number of floors of the first floor to the n-th floor of the building. For example, the terminal B ₁ represents a terminal corresponding to the first floor. Terminal B2 is a terminal corresponding to the second floor. Terminal B _n is a terminal corresponding to the n-th floor. Therefore, when the receiver 30 determines that the fire occurrence floor is the second floor, the area acoustic control signal from the terminal B2 corresponding to the fire occurrence floor to the light control device 50 from the terminal B3 corresponding to the floor immediately above the fire occurrence floor Output Note that the terminals of the terminal B ₁ .about.B _n, are connected to the signal line local sound devices installed on each floor through the (not shown). For example, a district acoustic device is an emergency bell. Therefore, when the district acoustic device acquires the district acoustic control signal supplied from the receiver 30, it emits an alarm. However, the receiver 30A controls the regional sound device so that the regional sound device does not ring when emergency broadcasting is in progress. In addition, the receiver 30 is based on the table which set the detection lines 4-1 to 4-n which are interlocking sources and the terminals B _{1 to} B _n which are interlocking destinations stored in the own apparatus, The terminal B for outputting the control signal may be determined. For example, the receiver 30 determines, from the table, the terminal B corresponding to the detection line to which the district acoustic control signal is input, to thereby determine the terminal B for outputting the district acoustic control signal.

The receiver 30 selects a specific terminal EA from the terminals EA _{1 to} EA _n based on the fire detection signal supplied from the detector 5. The receiver 30 outputs an alert transfer signal to the emergency broadcast facility 40 from the selected terminal EA. The details will be described below. The receiver 30 outputs an alarm transfer notification signal from the terminal EA corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor. Here, the terminals EA _{1 to} EA _n are terminals corresponding to the number of floors of the first floor to the n th floor of the building. For example, the terminal EA ₁ is a terminal corresponding to the first floor. Terminal EA2 is a terminal corresponding to the second floor. Terminal EA _n is a terminal corresponding to the n-th floor. Therefore, when the receiver 30 determines that the fire occurrence floor is on the second floor, it transfers a notification to the emergency broadcast facility 40 from the terminal EA2 corresponding to the fire occurrence floor and the terminal EA3 corresponding to the floor immediately above the fire occurrence floor. Output an information signal. In addition, the receiver 30 is notified based on the table which set the detection lines 4-1 to 4-n which are interlocking sources and the terminals EA _{1 to} EA _n which are interlocking destinations stored in the own apparatus. A terminal EA for outputting a mobile alert signal may be determined. For example, the receiver 30 determines, from the above table, the terminal EA corresponding to the detection line to which the fire detection signal has been input, to thereby determine the terminal EA for outputting the alert transition signal.

  The receiver 30 will confirm that the fire occurred, if the 2nd fire detection signal which the detector 5 alerted is acquired. When the receiver 30 acquires the second fire detection signal issued by the detector 5, the receiver 30 outputs a determination signal from the terminal EF. The terminal EF is connected to the emergency broadcast facility 40 via the signal line 32. The terminal EF is connected to the emergency broadcast facility 40A via the signal line 34. Therefore, the decision signal is output to the emergency broadcast facility 40 and the light control device 50.

  The speakers 20 are disposed on the ceiling or wall of each floor of the building. Specifically, one or a plurality of speakers 20 are disposed in predetermined broadcast areas, such as each floor, at legal installation intervals. The speaker 20 is connected to the emergency broadcast facility 40 via the broadcast line 19 (19-1 to 19-n). In the present embodiment, the speakers 20 disposed on the first floor are connected to the emergency broadcast facility 40 via the broadcast line 19-1. The speakers 20 disposed on the second floor are connected to the emergency broadcast facility 40 via the broadcast line 19-2. The speakers 20 arranged on the nth floor are connected to the emergency broadcast facility 40 via the broadcast lines 19-n. The emergency broadcast facility 40 outputs the acquired emergency broadcast message from the speaker 20 as a voice via the broadcast line 19.

  When a fire occurs, the emergency broadcast facility 40 broadcasts a predetermined emergency broadcast message recorded in advance via the speaker 20 installed in a predetermined broadcast area. As described above, the emergency broadcast by the emergency broadcast facility 40 is to warn by voice from the speaker 20 installed in the broadcast area, and broadly divided into alert broadcast, fire broadcast and non-fire broadcast.

  The alert broadcast is an emergency broadcast performed interlockingly when the receiver 30 acquires the first fire detection signal. For example, the emergency broadcast message of the report broadcast is "The fire detector on the first floor has just been activated. A staff member has confirmed it, so please be careful with the next broadcast."

  A fire broadcast is an emergency broadcast that is performed when the occurrence of a fire is determined after an alert broadcast. For example, the emergency broadcast message of the fire broadcast is "fires, fires, fires have occurred on the nth floor. Please calm down and evacuate."

  The non-fire broadcast is an emergency broadcast performed when the receiver 30 determines that it is not a fire after acquiring the first fire detection signal. For example, the non-fire broadcast emergency broadcast message is "The operation of the fire detector has not been found abnormal as a result of confirmation. Please rest assured".

Hereinafter, the specific configuration and operation of the emergency broadcast facility 40 will be described with reference to FIG. FIG. 2 is a diagram showing an example of a schematic configuration of the emergency broadcast equipment 40 in the first embodiment.
As shown in FIG. 2, the emergency broadcast facility 40 includes a third timer 41, a fourth timer 42, a control unit 43, and a storage unit 44.

The third timer 41 starts clocking when it receives an alarm transfer notification signal supplied from the receiver 30 via the terminal EA.
The fourth timer 42 starts clocking when the fire broadcast is started.

The control unit 43 determines the fire occurrence floor and the floor immediately above the fire occurrence floor when acquiring the alarm transfer notification signal supplied from the receiver 30 via the terminal EA. For example, the control unit 43 includes a plurality of terminals H1 to Hn corresponding to the terminals EA _{1 to} EA _{n on} a one-to-one basis. Therefore, the control unit 43 determines the fire occurrence floor and the floor immediately above the fire occurrence floor by determining the terminal to which the alert transfer notification signal is input among the terminals H1 to Hn. Note that the fire occurrence floor and the floor immediately above the fire occurrence floor can be determined, for example, by the number of floors corresponding to any one of the terminals H1 to Hn to which the alert transfer notification signal supplied from the receiver 30 first is input. Indicates the fire occurrence floor. The correspondence relationship between the terminals H1 to Hn and the number of floors of each floor of the building is stored in advance in the storage unit 44. Therefore, the control unit 43 determines the fire occurrence floor and the floor immediately above the fire occurrence floor by reading out from the storage unit 44 the floor number of the building associated with the terminal to which the alert transfer notification signal is input. The control unit 43 performs an alert broadcast by transmitting an emergency broadcast message of the alert broadcast to the determined fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor. The emergency broadcast message of the alert broadcast is stored in advance in the storage unit 44.

Control unit 43, the time the third timer 41 has timed (hereinafter, referred to as "measurement time".) If the T ₃ has reached the third set time T _th3, it stops the alarm broadcast proceeds to fire broadcast. Therefore, the control unit 43 transmits the emergency broadcast message of the fire broadcast to the determined fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor to perform fire broadcast. The emergency broadcast message of the fire broadcast is stored in advance in the storage unit 44. The third set time T _th3 is a time from the alert broadcast to the fire broadcast. However, the control unit 43, when the counted time T ₃ of the third timer 41 to obtain a confirmation signal from the receiver 30 when it is less than the third set time T _th3, stops the alarm broadcast proceeds to fire broadcast. That is, the control unit 43 acquires the determination signal from the receiver 30, even the counted time T ₃ is lower than the third set time T _th3 stop alarm broadcast, the process proceeds to fire broadcast. Incidentally, when a transition is made to a fire broadcasting, the counting time T ₃ of the third timer 41 is reset to the initial value. For example, the initial value is zero.

Control unit 43, if the measured time T ₄ of the fourth timer 42 has reached the fourth predetermined time T _th4, starts entire simultaneous broadcast intended for all broadcast zone. That is, the control unit 43 transmits the emergency broadcast message of the fire broadcast to the speakers 20 installed in all the broadcast areas to shift to the fire broadcast of the entire building. The fourth set time T _th4 is a time until transition from fire broadcast to simultaneous broadcast.

  The light alarm device 10 is disposed on the ceiling or wall of each floor of the building. Specifically, one or more light alarm devices 10 are disposed in the alarm area of each floor at predetermined installation intervals. The light alarm device 10 is connected to the light control device 50 via the light alarm line 9 (light alarm lines 9-1 to 9-n).

When the light alarm device 10 is supplied with power from the light control device 50 through the light alarm line 9, the light alarm device 10 performs a light alarm (hereinafter referred to as "light alarm"). The light alarm is to make the light emitter provided in the light alarm device 10 emit light. For example, the light emitter is a light source such as an electronic flash represented by a strobe (registered trademark) that emits an intense flash of light or an LED lamp with a large amount of light. When the power is supplied, the light alarm device 10 blinks the light emitter to notify people in the building of the occurrence of a disaster. In the present embodiment, the light alarm device 10 disposed on the first floor is supplied with power from the light control device 50 via the light alarm line 9-1.
The light alarm device 10 disposed on the second floor is supplied with power from the light control device 50 via the light alarm line 9-2. The light alarm device 10 disposed on the nth floor is supplied with power from the light control device 50 via the light alarm line 9-n.

Hereinafter, the light control device 50 of the present embodiment will be described with reference to FIG. FIG. 3 is a diagram showing an example of a schematic configuration of the light control device 50 in the first embodiment.
The light control device 50 includes a first timer 51, a second timer 52, and a control unit 53.

When the first timer 51 acquires the regional acoustic control signal supplied from the receiver 30 via the terminal B, it starts clocking.
When the second timer 52 acquires the determination signal supplied from the receiver 30 via the terminal EF, it starts clocking. When the second timer 52 acquires a control signal supplied from the control unit 53, the second timer 52 starts clocking.

When the control unit 53 acquires the district acoustic control signal supplied from the receiver 30 via the terminal B, the control unit 53 determines the fire occurrence floor and the floor immediately above the fire occurrence floor. For example, the control unit 53 includes a plurality of terminals P1 to Pn corresponding to the terminals B _{1 to} B _{n on} a one-to-one basis. Therefore, the control unit 53 determines the fire generation floor and the floor immediately above the fire generation floor by determining the terminal to which the area acoustic control signal is input among the terminals P1 to Pn. In addition, for the determination of the fire occurrence floor and the floor immediately above the fire occurrence floor, for example, the number of floors corresponding to any one of the terminals P1 to Pn to which the area acoustic control signal supplied from the receiver 30 is input is fire Indicates the occurrence floor. The correspondence relationship between the terminals P1 to Pn and the number of floors of each floor of the building is stored in advance in the storage unit 54. Therefore, the control unit 53 determines the fire occurrence floor and the floor immediately above the fire occurrence floor by reading out from the storage unit 54 the floor number of the building associated with the terminal to which the district acoustic control signal is input. The control unit 53 supplies power to the determined fire occurrence floor and the light alarm device 10 installed immediately above the fire occurrence floor, thereby enabling the light alarm device 10 of the fire occurrence floor and the light warning device 10 immediately above the fire occurrence floor to be determined. Give an alarm (hereinafter referred to as "divided light alarm").

Control unit 53, the counted time _{T 1} of the first timer 51 when it reaches the first set time _{T th1,} and outputs a control signal to the second timer 52. The first set time T _th1 is the same as the third set time T _th3 (T _th1 = T _th3 ). The second timer 52 starts clocking by acquiring the control signal supplied from the control unit 53. Therefore, the second timer 52 can clock at the timing when the emergency broadcast facility 40 shifts from alert broadcast to fire broadcast. However, the second timer 52 is counting the time T ₁ of the first timer 51 starts counting when acquiring the confirmation signal from the receiver 30 when it is less than the T _th1 first set time. That is, the second timer 52 acquires the determination signal from the receiver 30, even counted time T ₁ is less than T _th1 first set time starts counting. Therefore, the second timer 52 can count at the timing when the emergency broadcast facility 40 acquires the decision signal. That is, the second timer 52 can measure the timing at which the emergency broadcast facility 40 transitions from the alert broadcast to the fire broadcast by acquiring the decision signal from the receiver 30. If the second timer 52 starts counting, the counted time T ₁ of the first timer 51 is reset to the initial value. For example, the initial value is zero.

Control unit 53 determines that the measured time T ₂ of the second timer 52 when it reaches the T _th2 second set time, emergency broadcast facility 40 is shifted simultaneously broadcast from a fire broadcasting. When the control unit 53 determines that the emergency broadcast facility 40 has shifted from fire broadcast to simultaneous broadcast, it supplies power to all the light alarm devices 10 installed on each floor. Thus, the control unit 53 shifts to a light alert of the entire building. The second set time T _th2 is the same as the fourth set time T _th4 (T _th2 = T _th4 ). Therefore, the control unit 53 can shift to a light alert (hereinafter referred to as "simultaneous light alert") of the entire building at the same time as the emergency broadcast facility 40 shifts from fire broadcast to simultaneous broadcast.

Hereinafter, the operation at the time of fire occurrence of the emergency broadcast facility 40 of the first embodiment will be described using FIG. 4. FIG. 4 is a diagram for explaining the process flow of the operation of the emergency broadcast facility 40 in the first embodiment.
The receiver 30 determines the fire occurrence floor and the floor immediately above the fire occurrence floor based on the fire detection signal supplied from the detector 5. Then, the receiver 30 outputs an alarm transfer notification signal from the terminal EA corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor. Thereby, the emergency broadcast facility 40 acquires the alert transition signal supplied from the receiver 30 when a fire occurs (step S101).

  The third timer 41 starts clocking from the time when the alarm transfer notification signal is supplied from the receiver 30 (step S102).

  The control unit 43 performs alert broadcast by transmitting an emergency broadcast message of alert broadcast to the determined fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor (step S103).

Control unit 43 determines whether the counted time _{T 3} of the third timer 41 has reached a third set time _{T th3.} Control unit 43, if the counted time _{T 3} of the third timer 41 has reached a third set time _{T th3,} the process proceeds to step S105. On the other hand, the control unit 43, the counting time _{T 3} of the third timer 41 (less than) the third does not reach the set time _{T th3} case, the process proceeds to step S109 (step S104).

  The control unit 43 stops the alert broadcast and shifts to fire broadcast (step S105).

  The fourth timer 42 starts clocking at the same time as the fire broadcast is started (step S106).

Control unit 43 determines whether the counted time _{T 4} of the fourth timer 42 has reached the fourth predetermined time _{T th4.} Control unit 43, if the measured time _{T 4} of the fourth timer 42 has reached the fourth predetermined time _{T th4,} the process proceeds to step S108. On the other hand, the control unit 43, the counting time _{T 4} of the fourth timer 42 (less than) the fourth does not reach the set time _{T th4} case, the process of step S107 again (step S107).

Control unit 43, if the measured time _{T 4} of the fourth timer 42 has reached the fourth predetermined time _{T th4,} starts entire simultaneous broadcast intended for all broadcast zone (step S108).

The control unit 43 determines whether or not the determination signal supplied from the receiver 30 has been acquired. When the control unit 43 acquires the determination signal, the control unit 43 proceeds to the process of step S105. When the control unit 43 has not acquired the determination signal, the control unit 43 proceeds to the process of step S104. That is, the control unit 43 acquires the determination signal from the receiver 30 when the counted time T ₃ is less than the third set time T _th3, it stops the alarm broadcast proceeds to fire broadcast (step S109).

  Hereinafter, the operation of the light control device 50 according to the first embodiment when a fire occurs will be described with reference to FIG. FIG. 5 is a diagram for explaining the processing flow of the operation of the light control device 50 in the first embodiment.

  The receiver 30 determines the fire occurrence floor and the floor immediately above the fire occurrence floor based on the fire detection signal supplied from the detector 5. Then, the receiver 30 outputs a regional acoustic control signal from the terminal B corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor. Thus, when a fire occurs, the light control device 50 acquires the regional acoustic control signal supplied from the receiver 30 (step S201).

  The first timer 51 starts clocking from the time when the regional acoustic control signal is supplied from the receiver 30 via the terminal B (step S202).

  The control unit 53 supplies power to the fire alarm floor and the light alarm device 10 installed on the floor immediately above the fire alarm floor, so that the divided light alarm by the light alarm device 10 on the fire alarm floor and the floor immediately above the fire alarm floor is provided. (Step S203).

Control unit 53, the counted time _{T 1} of the first timer 51 determines whether or not reached the first set time _{T th1} is the same as the third set time _{T th3} (step S204). Control unit 53, when the counted time _{T 1} is reached the first set time _{T th1,} the process proceeds to step S205. On the other hand, the control unit 53, the counted time _{T 1} is (less than) that reaches not the first set time _{T th1} case, the process proceeds to step S209.

Control unit 53, the counted time _{T 1} of the first timer 51 detects that has reached the first set time _{T th1,} and outputs a control signal to the second timer 52 (step S205).

  The second timer 52 starts clocking from the time when the control signal is supplied from the control unit 53. As a result, the second timer 52 can count the timing at which the emergency broadcast facility 40 has shifted from alert broadcast to fire broadcast (step S206).

Control unit 53, the counting time _{T 2} of the second timer 52 determines whether or not reached the second set time Tth ₂ is identical to the fourth set time _{T th4} (step S207). Control unit 53, when the counted time _{T 2} has reached the Tth ₂ second set time, the process proceeds to step S208. On the other hand, the control unit 53, the counting time _{T 2} is (less than) the second does not reach the set time _{T th2} case, the process proceeds to step S207.

Control unit 53 supplies the counted time T ₂ of the second timer 52 detects that the reached T _th2 second set time, the power to all the optical alarm device 10 installed on each floor. Thereby, the control unit 53 shifts to the simultaneous light alarm (step S208). Therefore, the control unit 53 can shift to the simultaneous light alarm at the timing when the emergency broadcast facility 40 shifts from fire broadcast to simultaneous broadcast.

The control unit 53 determines whether or not the determination signal supplied from the receiver 30 has been acquired (step S209). When the control unit 53 acquires the determination signal, the control unit 53 proceeds to the process of step S205. When the control unit 53 has not acquired the determination signal, the control unit 53 proceeds to the process of step S204. That is, the control unit 53 acquires the determination signal from the receiver 30 when the counted time T ₁ is less than T _th1 first set time, outputs a control signal to the second timer 52. Thus, the second timer 52 starts measuring at the time the measurement time T ₁ is determined signal from the receiver 30 when it is less than the T _th1 first set time is supplied.

  Hereinafter, the flow of processing of the alarm system 1 at the time of fire occurrence in the first embodiment will be described using FIGS. 6 and 7. In addition, the process of the alarm system 1 at the time of the fire occurrence shown below is a case where the detector 5 does not issue the fire detection signal of the 2nd report.

FIG. 7 is a timing chart showing an example of the flow of processing of the alarm system 1 at the time of fire occurrence in the first embodiment.

  First, when detecting the occurrence of a fire, the detector 5 outputs a fire detection signal indicating the occurrence of a fire to the receiver 30 via the detection line 4 (step S301). When the fire detection signal is obtained, the receiver 30 outputs a fire alarm / deletion signal from the terminal EA corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor to the emergency broadcast facility 40 (step S302). The receiver 30 also outputs a regional acoustic control signal from the terminal B corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor to the light control device 50 simultaneously with the output of the alert transmission signal (step S303).

  When the emergency broadcast facility 40 acquires the area acoustic control signal supplied from the receiver 30, it transmits the emergency broadcast message of the alert broadcast to the fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor. , And broadcast an alert (step S304). On the other hand, when the light control device 50 acquires the district acoustic control signal supplied from the receiver 30, the fire is generated by supplying power to the fire occurrence floor and the light alarm device 10 installed immediately above the fire occurrence floor. The divided light alarm of the light alarm device 10 immediately above the generation floor and the fire generation floor is performed (step S305). Here, the alert broadcast and the divided light alarm are performed at the same timing.

  When the emergency broadcast equipment 40 acquires the alarm transfer notification signal supplied from the receiver 30, it starts timing of the third timer 41 (step S306). On the other hand, when the light control device 50 acquires the regional acoustic control signal supplied from the receiver 30, the light control device 50 starts clocking of the first timer 51 (step S307).

Emergency broadcast facility 40, when the counted time _{T 3} of the third timer 41 detects that you have reached the third set time _{T th3,} stops the alarm broadcast proceeds to fire broadcast (step S308). On the other hand, the light control device 50 outputs when detecting that the counted time _{T 1} of the first timer 51 has reached the first set time _{T th1,} a control signal to the second timer 52 (step S309).

When the emergency broadcast facility 40 stops the alert broadcast and shifts to fire broadcast, it starts clocking of the fourth timer 42 (step S310). On the other hand, the second timer 52 of the light control device 50 starts clocking when acquiring the control signal. (Step S311). Here, since the third set time _Tth3 and the first set time _Tth1 are the same, the timings of the fourth timer 42 and the second timer 52 are the same.

Emergency broadcast facility 40, the entire by the counting time T ₄ of the fourth timer 42 is to send emergency broadcast messages fire broadcast fourth when it reaches the set time T _th4, a speaker 20 installed in all broadcast zone It shifts to simultaneous fire broadcast (step S312). On the other hand, the light control device 50, when the counted time T ₂ of the second timer 52 has reached the T _th2 second set time, and supplies power to all the optical alarm device 10 installed on each floor. Thereby, the light control device 50 shifts to the simultaneous light alarm (step S313). Here, since the second set time _Tth2 and the fourth set time _Tth4 are the same, the simultaneous broadcast and the simultaneous light alarm are performed at the same timing.

  Hereinafter, the flow of processing of the alarm system 1 at the time of fire occurrence in the first embodiment will be described using FIGS. 8 and 9. In addition, the process of the alarm system 1 at the time of a fire occurrence shown below is a case where the detector 5 outputs the 2nd fire detection signal. FIG. 8 is a sequence diagram showing another example of the process flow of the alarm system 1 at the time of fire occurrence in the first embodiment. FIG. 9 is a timing chart showing another example of the process flow of the alarm system 1 at the time of fire occurrence in the first embodiment.

  First, when detecting the occurrence of a fire, the detector 5 outputs a fire detection signal indicating the occurrence of a fire to the receiver 30 via the detection line 4 (step S401). Upon acquiring the fire detection signal, the receiver 30 outputs a warning / deletion signal from the terminal EA corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor to the emergency broadcast facility 40 (step S402). Further, the receiver 30 outputs a regional acoustic control signal to the light control device 50 from the terminal B corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor simultaneously with the output of the alert transfer notification signal (step S403).

  When the emergency broadcast facility 40 acquires the area acoustic control signal supplied from the receiver 30, it transmits the emergency broadcast message of the alert broadcast to the fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor. , Broadcast an alert (step S404). On the other hand, when the light control device 50 acquires the district acoustic control signal supplied from the receiver 30, the fire is generated by supplying power to the fire occurrence floor and the light alarm device 10 installed immediately above the fire occurrence floor. The divided light alarm of the light alarm device 10 immediately above the generation floor and the fire generation floor is performed (step S405). Here, the alert broadcast and the divided light alarm are performed at the same timing.

  When the emergency broadcast equipment 40 acquires the alarm transfer notification signal supplied from the receiver 30, it starts timing of the third timer 41 (step S406). On the other hand, when the light control device 50 acquires the regional acoustic control signal supplied from the receiver 30, the light control device 50 starts clocking of the first timer 51 (step S407).

The detector 5 outputs the second fire detection signal to the receiver 30 via the detection line 4 (step S408).
The receiver 30 will confirm that the fire occurred, if the 2nd fire detection signal which the detector 5 alerted is acquired. When the receiver 30 acquires the second fire detection signal issued by the detector 5, the receiver 30 outputs a determination signal to the emergency broadcast facility 40 (step 409). When the receiver 30 acquires the second fire detection signal issued by the detector 5, the receiver 30 outputs a determination signal to the light control device 50 (step 409). The timing at which the receiver 30 outputs the determination signal to the light control device 50 and the emergency broadcast facility 40 is the same.

Emergency broadcast facility 40, when the counted time T ₃ of the third timer 41 to obtain a confirmation signal from the receiver 30 when it is less than the third set time T _th3, stops the alarm broadcast proceeds to fire broadcast (step S411). On the other hand, the light control device 50 outputs the measured time T ₁ of the first timer 51 obtains a determination signal from the receiver 30 when it is less than the T _th1 first set time, a control signal to the second timer 52 ( Step S412).

  When the emergency broadcast facility 40 stops the alert broadcast and shifts to fire broadcast, it starts clocking of the fourth timer 42 (step S413). On the other hand, the second timer 52 of the light control device 50 starts counting from the time when the control signal is supplied. (Step S414).

Emergency broadcast facility 40, the entire by the counting time T ₄ of the fourth timer 42 is to send emergency broadcast messages fire broadcast fourth when it reaches the set time T _th4, a speaker 20 installed in all broadcast zone It shifts to simultaneous fire broadcasting (step S415). On the other hand, the light control device 50, when the counted time T ₂ of the second timer 52 has detected that reaches the T _th2 second set time, and supplies power to all the optical alarm device 10 installed on each floor. Thereby, the light control device 50 shifts to the simultaneous light alarm (step S416). Here, since the second set time _Tth2 and the fourth set time _Tth4 are the same, the emergency broadcast and the simultaneous light alert are performed at the same timing.

As described above, the alarm system 1 of the first embodiment includes the emergency broadcast facility 40, the receiver 30, and the light control device 50. The light control device 50 includes a first timer 51, a second timer 52, and a control unit 53. The first timer 51 counts time when acquiring the regional acoustic control signal supplied from the receiver 30. The second timer 52 is counting the time _{T 1} of the first timer 51 starts counting when it detects that it has reached the first set time _{T th1.} Control unit 53 determines that the counted time T ₂ is the second set time T _th2 emergency broadcast facility 40 when it is detected that reached shifts to the broadcast simultaneously, the light alarm device installed in all alarm zone Supply power to 10. As a result, since the alarm system 1 executes the simultaneous broadcasting of the emergency broadcasting facility 40 and the simultaneous light alarm of the light alarm device 10 at the same timing, the light alarm is generated despite the occurrence of a disaster such as a fire. It is possible to prevent the problem that there are floors that have not been That is, the emergency broadcast of the emergency broadcast facility 40 and the light alarm of the light alarm device 10 can be executed simultaneously. Therefore, it is possible to suppress misunderstanding that no disaster has occurred even though a disaster such as a fire has occurred to people in the building.

  In the first embodiment described above, the case where the receiver 30 outputs the confirmation signal from the terminal EF when the second fire detection signal of the detector 5 is acquired is described. It is not limited. For example, the receiver 30 outputs a determination signal from the terminal EF when the fire determination switch provided in the receiver 30 is operated after acquiring the first fire detection signal reported by the detector 5 Do. For example, the receiver 30 outputs a determination signal from the terminal EF when acquiring a transmitter alert from the transmitter.

Second Embodiment
Next, an alarm system 1A of the second embodiment will be described. FIG. 10 is a diagram showing an example of a schematic configuration of an alarm system 1A in the second embodiment. In the following description, the same parts as those in the first embodiment will be assigned the same reference numerals and detailed explanations thereof will be omitted.
The alarm system 1A includes an emergency broadcast facility 40A and a controller (receiver 30A and light controller 50A). The emergency broadcast facility 40A outputs a simultaneous broadcast signal indicating that simultaneous broadcast is to be performed to the receiver 30A or the light control device 50A when the fire broadcast is shifted to the simultaneous broadcast. When acquiring the simultaneous broadcast signal supplied from the emergency broadcast facility 40A, the control device determines that the emergency broadcast facility has shifted from the fire broadcast to the simultaneous broadcast, and performs a light alert simultaneously throughout the building.

  The alarm system 1A includes a plurality of detectors 5 (detectors 5-1 to 5-n), a plurality of light alarm devices 10, a plurality of speakers 20, a receiver 30A, an emergency broadcast facility 40A, and a light control device 50A. The receiver 30A and the light control device 50A described below may be configured as a control device. Further, the alarm system 1A includes a plurality of detectors 5, a plurality of light alarm devices 10, a plurality of speakers 20, a receiver 30A, an emergency broadcast facility 40A, and a light control device 50A, but is not limited thereto. For example, the alarm system 1A may be provided with a receiver 30A, an emergency broadcast facility 40A, and a light control device 50A.

The receiver 30A includes terminals B (B _{1 to} B _n ), terminals EA (EA _{1 to} EA _n ), a terminal KK, and a terminal KL. The terminal KK is connected to the emergency broadcast facility 40A via the signal line 35. The terminal KL is connected to the light control device 50A via the signal line 36.

When the receiver 30A acquires the fire detection signal supplied from the detector 5, the receiver 30A specifies the fire occurrence floor. The receiver 30A outputs a regional acoustic control signal to the light control device 50A from the terminals B corresponding to the identified fire occurrence floor and the floor immediately above the fire occurrence floor. Note that the terminals of the terminal B ₁ .about.B _n, are connected to the signal line local sound devices installed on each floor through the (not shown). For example, a district acoustic device is an emergency bell. Therefore, when the district acoustic device acquires the district acoustic control signal supplied from the receiver 30A, the district acoustic device sounds an alarm.
The receiver 30A outputs an alert transfer signal to the emergency broadcast facility 40A from each terminal EA corresponding to the determined fire floor and the floor immediately above the fire floor.

  The receiver 30A acquires the simultaneous broadcast signal supplied from the emergency broadcast facility 40A via the signal line 35. The simultaneous broadcast signal is a signal indicating that the emergency broadcast facility 40A is performing simultaneous broadcast. The simultaneous broadcast signal is supplied from the emergency broadcast facility 40A to the receiver 30A at the timing of transition from fire broadcast to simultaneous broadcast. Upon acquiring the simultaneous broadcast signal supplied from the emergency broadcast facility 40A, the receiver 30A determines that the emergency broadcast facility 40A has shifted from the fire broadcast to the simultaneous broadcast. Then, the receiver 30A outputs the simultaneous light alarm signal to the light control device 50A via the signal line 36. The simultaneous light alarm signal is a signal for causing the light control device 50A to perform the simultaneous light alarm.

Hereinafter, a specific configuration and operation of the emergency broadcast facility 40A will be described with reference to FIG. FIG. 11 is a diagram showing an example of a schematic configuration of the emergency broadcast equipment 40A in the second embodiment.
As shown in FIG. 11, the emergency broadcast facility 40A includes a third timer 41, a fourth timer 42, a control unit 43A, and a storage unit 44.

  The control unit 43A determines the fire occurrence floor and the floor immediately above the fire occurrence floor when acquiring the alarm transfer notification signal supplied from the receiver 30A via the terminal EA. Control part 43A performs alert broadcast by transmitting the emergency broadcast message of alert broadcast to the determined fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor. The emergency broadcast message of the alert broadcast is stored in advance in the storage unit 44.

Control unit 43A, when the counted time _{T 3} of the third timer 41 has reached a third set time _{T th3,} it stops the alarm broadcast proceeds to fire broadcast. Therefore, the control unit 43A transmits the emergency broadcast message of the fire broadcast to the determined fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor to perform the fire broadcast.

Control unit 43A, when the counted time T ₄ of the fourth timer 42 has reached the fourth predetermined time T _th4, starts entire simultaneous broadcast intended for all broadcast zone. That is, the control unit 43A shifts to the fire broadcast of the entire building by transmitting the emergency broadcast message of the fire broadcast to the speakers 20 installed in all the broadcast areas.
Control part 43A outputs a simultaneous broadcast signal to receiver 30A, when it shifts to whole building simultaneous broadcast.

  When the light control device 50A acquires the district acoustic control signal supplied from the receiver 30A via the terminal B, it determines the fire occurrence floor and the floor immediately above the fire occurrence floor. The light control device 50A supplies power to the determined fire occurrence floor and the light alarm device 10 installed immediately above the fire occurrence floor, thereby the fire occurrence floor and the light warning device 10 directly above the fire occurrence floor. The division light alarm is performed.

  The light control device 50A supplies power to all the light alarm devices 10 installed on each floor when acquiring the simultaneous light alarm signal supplied from the receiver 30A. Thereby, the light control device 50A shifts to a light alert of the entire building. Therefore, the light control apparatus 50A can shift to the simultaneous light alert of the entire building at the timing when the emergency broadcast facility 40A shifts from the fire broadcast to the simultaneous broadcast.

  Hereinafter, the flow of processing of the alarm system 1A at the time of fire occurrence in the second embodiment will be described using FIGS. 12 and 13. FIG. 12 is a sequence diagram showing an example of a process flow of the alarm system 1A at the time of fire occurrence in the second embodiment. FIG. 13 is a timing chart showing an example of the process flow of the alarm system 1A at the time of fire occurrence in the second embodiment.

  First, when the occurrence of a fire is detected, the detector 5 outputs a fire detection signal indicating the occurrence of a fire to the receiver 30A via the detection line 4 (step S501). Upon acquiring the fire detection signal, the receiver 30A outputs a notification transfer signal to the emergency broadcast facility 40A from each terminal EA corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor (step S502). In addition, the receiver 30A outputs a regional acoustic control signal from the terminals B corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor to the light control device 50A simultaneously with the output of the alert transfer notification signal (step S503) .

  When the emergency broadcast facility 40A acquires the district acoustic control signal supplied from the receiver 30A, it transmits the emergency broadcast message of the alert broadcast to the fire occurrence floor and the speaker 20 installed immediately above the fire occurrence floor. , And broadcast an alert (step S504). On the other hand, when the light control device 50A acquires the district acoustic control signal supplied from the receiver 30A, the fire is generated by supplying power to the fire alarm floor and the light alarm device 10 installed immediately above the fire alarm floor. The divided light alarm of the light alarm device 10 immediately above the generation floor and the fire generation floor is performed (step S505). Here, the alert broadcast and the divided light alarm are performed at the same timing.

  The third timer 41 of the emergency broadcast facility 40A starts clocking from the time when the alert transfer notification signal is supplied from the receiver 30A (step S506).

Emergency broadcast equipment 40A, when the counted time _{T 3} of the third timer 41 detects that you have reached the third set time _{T th3,} stops the alarm broadcast proceeds to fire broadcast (step S507).

  The fourth timer 42 of the emergency broadcast facility 40A stops the alert broadcast and starts clocking when shifting to the fire broadcast (step S508).

Emergency broadcast equipment 40A is entire by the counting time T ₄ of the fourth timer 42 is to send emergency broadcast messages fire broadcast fourth when it reaches the set time T _th4, a speaker 20 installed in all broadcast zone It shifts to a simultaneous fire broadcast (step S509). Further, when the light control device 50A shifts to the fire broadcast all over the building at the same time, the light control device 50A outputs the simultaneous broadcast signal to the receiver 30A (step S510).

  When the receiver 30A acquires the simultaneous broadcast signal supplied from the emergency broadcast facility 40A, the receiver 30A outputs a simultaneous light alarm signal to the light control device 50A (step S511). Upon acquiring the simultaneous light alarm signal supplied from the receiver 30A, the light control device 50A supplies power to all the light alarm devices 10 installed on each floor. Thereby, the light control device 50A shifts to the simultaneous light alarm (step S512). Thus, the light control device 50A executes the simultaneous light alarm when acquiring the simultaneous light alarm signal output based on the simultaneous broadcast signal. Therefore, the simultaneous broadcast and the simultaneous light alert are performed at the same timing.

  As described above, the alarm system 1A of the second embodiment includes the emergency broadcast facility 40A, the receiver 30A, and the light control device 50A. The emergency broadcast facility 40A outputs the simultaneous broadcast signal to the receiver 30A when transitioning from fire broadcast to simultaneous broadcast. The light control device 50A controls the light control device 50A so as to perform the light alarm of the entire building of the light alarm device 10 simultaneously when acquiring the simultaneous broadcast signal supplied from the emergency broadcast facility 40A. As a result, since the alarm system 1A executes the simultaneous broadcasting of the emergency broadcast facility 40A and the simultaneous light alarm of the light alarm device 10 at the same timing, the light alarm is generated despite the occurrence of a disaster such as a fire. It is possible to prevent the problem that there are floors that have not been That is, it is possible to simultaneously execute the emergency broadcast of the emergency broadcast facility 40A and the light alarm of the light alarm device 10. Therefore, it is possible to suppress misunderstanding that no disaster has occurred even though a disaster such as a fire has occurred to people in the building.

  In addition, the receiver is provided with a stop timer that sets the time for transitioning from the segment ringing to the entire area ringing. However, the setting time of the stop timer can only be set within 10 minutes according to the standard. On the other hand, since there is no particular limitation on the time during which the emergency broadcast (divided broadcast) of the regular broadcast facility 40A flows, it may be set to 20 minutes to 30 minutes by the user. Therefore, in the conventional alarm system, since the stop timer can not set the time to shift from divided broadcasting to simultaneous broadcasting as the set time, the timing between the simultaneous broadcasting of the emergency broadcasting facility and the simultaneous light alarm of the light alarm device is large. There is a risk of shifting. However, the alarm system 1A does not use (or invalidates) the stop timer, and performs the simultaneous light alarm on the basis of the broadcast signal supplied from the emergency broadcast facility 40A. Therefore, it is possible to prevent the timing of the simultaneous broadcast of the emergency broadcast facility and the simultaneous light alert of the light alarm device from being largely deviated.

  In the present embodiment, the emergency broadcast facility 40A outputs the simultaneous broadcast signal to the receiver 30A, but the present invention is not limited to this. For example, the emergency broadcast facility 40A may broadcast to the light control device 50A. In this case, when the light control device 50A acquires the simultaneous broadcast signal supplied from the emergency broadcast facility 40A, the light control device 50A supplies power to all the light alarm devices 10 installed on each floor and shifts to the simultaneous light alarm.

Third Embodiment
Next, an alarm system 1B of the third embodiment will be described. FIG. 14 is a diagram showing an example of a schematic configuration of an alarm system 1B in the third embodiment. In the following description, the same parts as those in the first embodiment will be assigned the same reference numerals and detailed explanations thereof will be omitted.

The alarm system 1B includes an emergency broadcast facility 40 and a controller (receiver 30B and light controller 50A). The control device starts counting when it outputs the alarm transfer signal, and when the counted time reaches the total value of the third set time T _th3 and the fourth set time T _th4 , the emergency broadcast facility 40 divides the broadcast It is determined that the broadcast has been switched to the simultaneous broadcast, and the simultaneous light alarm is issued. The timer for clocking may use the stop timer of the receiver 30B. However, when the occurrence of a fire is determined when the clocked time is less than the third set time T _th3 , the alarm system 1B is less than the total value of the third set time T _th3 and the fourth set time T _th4. Even if, broadcast and broadcast light alarm will be performed. In addition, determination of fire occurrence is not particularly limited, for example, acquisition of fire detection signal of the second report, operation of fire determination switch after acquisition of the first fire detection signal, or transmission of a transmitter from the transmitter It is acquisition.

  The alarm system 1B includes a plurality of detectors 5 (detectors 5-1 to 5-n), a plurality of light alarm devices 10, a plurality of speakers 20, a receiver 30B, an emergency broadcast facility 40, and a light control device 50A. Note that the receiver 30B and the light control device 50A described below may be configured as a control device. Further, the alarm system 1B includes a plurality of detectors 5, a plurality of light alarm devices 10, a plurality of speakers 20, a receiver 30B, an emergency broadcast facility 40, and a light control device 50A, but is not limited thereto. For example, the alarm system 1B may include the receiver 30B, the emergency broadcast facility 40, and the light control device 50A.

  Hereinafter, the specific configuration and operation of the receiver 30B in the third embodiment will be described using FIG. FIG. 15 is a diagram showing an example of a schematic configuration of the receiver 30B in the third embodiment.

As shown in FIG. 15, the receiver 30 </ b> B includes a stop timer 331 and a control unit 332. The receiver 30B includes terminals B (B _{1 to} B _n ), terminals EA (EA _{1 to} EA _n ), and a terminal KL.
The stop timer 331 starts clocking from the time when the fire detection signal is supplied from the detector 5. Alternatively, the stop timer 331 starts clocking when the control unit 332 outputs the area sound control signal or the alarm transfer signal. In the present embodiment, the stop timer 331 starts clocking when the alarm transfer signal is output to the emergency broadcast facility 40.

The control part 332 will specify a fire generation floor, if the fire detection signal supplied from the detector 5 is acquired. The control unit 332 outputs a regional acoustic control signal to the light control device 50A from the terminals B corresponding to the identified fire occurrence floor and the floor immediately above the fire occurrence floor. Note that the terminals of the terminal B ₁ .about.B _n, are connected to the signal line local sound devices installed on each floor through the (not shown). For example, a district acoustic device is an emergency bell. Therefore, when the district acoustic device acquires the district acoustic control signal supplied from the receiver 30B, the district acoustic device sounds an alarm.
The control unit 332 outputs an alert transfer signal to the emergency broadcast facility 40 from each terminal EA corresponding to the determined fire occurrence floor and the floor immediately above the fire occurrence floor.

When the clocked time _Tc of the stop timer 331 reaches the preset fifth clocked time T _th5 , the control unit 332 determines that the emergency broadcast facility 40 has shifted from divided broadcasting to simultaneous broadcasting. Then, the control unit 332 outputs the simultaneous light alarm signal to the light control device 50A via the signal line 36. The fifth clocked time _Tth5 is a value obtained by summing the third set time _Tth3 and the fourth set time _Tth4 .

  Hereinafter, the flow of processing of the alarm system 1B at the time of fire occurrence in the third embodiment will be described using FIG. 16 and FIG. FIG. 16 is a sequence diagram showing an example of a process flow of the alarm system 1B at the time of fire occurrence in the third embodiment. FIG. 17 is a timing chart showing an example of the process flow of the alarm system 1B at the time of fire occurrence in the third embodiment.

  First, when the occurrence of a fire is detected, the detector 5 outputs a fire detection signal indicating the occurrence of a fire to the receiver 30B via the detection line 4 (step S601). Upon acquiring the fire detection signal, the receiver 30B outputs a notification transfer notification signal to the emergency broadcast facility 40 from each terminal EA corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor (step S602). In addition, the receiver 30B outputs the area acoustic control signal from the terminals B corresponding to the fire occurrence floor and the floor immediately above the fire occurrence floor to the light control device 50A simultaneously with the output of the alert transfer notification signal (step S603) .

On the other hand, when the light control device 50A acquires the district acoustic control signal supplied from the receiver 30B, the fire occurs by supplying power to the fire alarm floor and the light alarm device 10 installed immediately above the fire alarm floor. The divided light alarm of the light alarm device 10 immediately above the generation floor and the fire generation floor is performed (step S605). Here, the alert broadcast and the divided light alarm are performed at the same timing.

  The stop timer 331 of the receiver 30B starts clocking when the alarm transfer notification signal is output to the emergency broadcast facility 40 (step S606). The third timer 41 of the emergency broadcast facility 40 starts counting from the time when the alert transfer notification signal is supplied from the receiver 30B (step S607).

Emergency broadcast facility 40, when the counted time _{T 3} of the third timer 41 detects that you have reached the third set time _{T th3,} stops the alarm broadcast proceeds to fire broadcast (step S608).

  The fourth timer 42 of the emergency broadcast facility 40 stops clocking broadcast and starts clocking when shifting to fire broadcasting (step S609).

Emergency broadcast facility 40, the entire by the counting time T ₄ of the fourth timer 42 is to send emergency broadcast messages fire broadcast fourth when it reaches the set time T _th4, a speaker 20 installed in all broadcast zone It shifts to simultaneous fire broadcast (step S610).
When the receiver 30B detects that the clocked time _Tc of the stop timer 331 has reached the fifth clocked time _Tth5 , the receiver 30B outputs a simultaneous light alarm signal to the light control device 50A (step S611). Here, since the fifth clocking time _Tth5 = the third setting time _Tth3 + the fourth setting time _Tth4 , the timing of the simultaneous light alarm signal output and the simultaneous broadcasting is the same.

  Upon acquiring the simultaneous light alarm signal supplied from the receiver 30B, the light control device 50A supplies power to all the light alarm devices 10 installed on each floor. Thereby, the light control device 50A shifts to the simultaneous light alarm (step S612). Therefore, the simultaneous broadcast and the simultaneous light alert are performed at the same timing.

As described above, the alarm system 1B of the third embodiment includes the emergency broadcast facility 40, the receiver 30B, and the light control device 50A. The receiver 30B starts clocking when the alarm / transfer signal is output, and the emergency broadcast facility 40 is classified when the clocked time reaches the total value of the third set time T _th3 and the fourth set time T _th4. It is determined that the broadcast has shifted to the broadcast. The receiver 30B outputs the simultaneous light alarm signal to the light control device 50A when it is determined that the divided broadcasting has shifted to the simultaneous broadcasting. When the simultaneous light alarm signal is acquired, the light control device 50A shifts to a simultaneous light alarm throughout the building. As a result, since the alarm system 1B executes the simultaneous broadcasting of the emergency broadcast facility 40 and the simultaneous light alarm of the light alarm device 10 at the same timing, the light alarm is generated despite the occurrence of a disaster such as a fire. It is possible to prevent the problem that there are floors that have not been That is, the emergency broadcast of the emergency broadcast facility 40 and the light alarm of the light alarm device 10 can be executed simultaneously. Therefore, it is possible to suppress misunderstanding that no disaster has occurred even though a disaster such as a fire has occurred to people in the building.

In the third embodiment, the alarm system 1B determines that the emergency broadcast facility 40 has shifted from divided broadcasting to simultaneous broadcasting only when the clocked time _Tc of the stop timer 331 reaches the fifth clocked time T _th5. Not limited to this. For example, the alarm system 1B may output a simultaneous broadcast signal from the emergency broadcast facility 40 in combination with the second embodiment. In that case, the alarm system 1B causes the emergency broadcast facility 40 to broadcast from the divided broadcast simultaneously based on whether the clocked time _Tc of the stop timer 331 reaches the fifth clocked time T _th5 or the broadcasted signal is acquired. It determines that it has shifted to the broadcast. Thereby, the alarm system 1B operates the stop timer 331 even when the signal line used to output the simultaneous broadcast signal from the emergency broadcast facility 40 to the receiver B is disconnected, thereby the emergency broadcast facility 40. The simultaneous broadcast and the simultaneous light alarm of the light alarm device 10 can be implemented at the same timing.

In the third embodiment, the receiver 30B may include the terminal EF, and when the occurrence of a fire is determined, the determination signal may be output from the terminal EF to the emergency broadcast facility 40 and the light control device 50A. That is, when the elapsed time from acquiring the fire detection signal of the first report is less than the third set time T _th3 , the alarm system 1B inputs the fire confirmation signal to the emergency broadcast facility 40 and the light control device 50A. Broadcast and broadcast light alarm.
