[0004] By the way, in the system provided with the fire detector, the guiding light, and the signal device for guiding lights described in Patent Document 1, when a fire occurs, the location of the fire can be notified to people inside the building, but there is a possibility that people outside the building cannot quickly grasp the occurrence of the fire inside the building.

[0005] The present invention has been made in view of the above reasons, and an object thereof is to provide a fire occurrence location notification system that can quickly notify the location of a fire inside a building to people outside the building when a fire occurs inside the building.

Means for Solving the Problems

[0006] To achieve the above object, the fire occurrence location notification system according to the present invention includes fire detectors installed in each of a plurality of areas inside a building, and The system comprises a plurality of fire alarm devices having a light source, installed at positions corresponding to each of the plurality of areas on the exterior wall of the building, and which illuminate or flash the light source in accordance with at least one of the plurality of areas where a fire has been detected by the fire detector. picture, The aforementioned building has multiple floors arranged in a vertical direction, Each of the aforementioned regions is a floor. Each of the aforementioned fire alarm devices is installed in a position corresponding to each of the aforementioned floors on the exterior wall of the building. . [Effects of the Invention]

[0007] According to the present invention, multiple fire alarm devices are installed at positions corresponding to multiple areas on the exterior wall of a building, and the light source is turned on or flashed depending on at least one of the multiple areas where a fire has been detected by a fire detector. As a result, if a fire occurs inside the building, a person outside the building can determine the area where a fire is occurring inside the building by looking at the location of the fire alarm device that is turning on or flashing its light source among the multiple fire alarm devices installed on the exterior wall of the building. Therefore, the location of a fire inside the building can be quickly notified to a person outside the building. [Brief explanation of the drawing]

[Figure 3] This is a block diagram showing the configuration of a fire alarm system according to an embodiment. [Figure 4] This flowchart shows an example of the fire alarm processing flow performed by the fire alarm system according to the embodiment. [Figure 5] This is a schematic diagram of a modified fire location notification system. [Modes for carrying out the invention]

[0009] Hereinafter, a fire location notification system according to an embodiment of the present invention will be described with reference to the drawings. The fire location notification system according to this embodiment comprises a fire detector installed in each of a plurality of areas within a building, and a plurality of fire alarm devices having a light source and installed at positions corresponding to each of the plurality of areas on the exterior wall of the building, which turn on or flash the light source in accordance with at least one of the plurality of areas in which a fire has been detected by the fire detector.

[0010] The fire location notification system according to this embodiment includes, for example, as shown in Figure 1, a plurality of fire detectors 2 (six in Figure 1) installed on each floor S1, S2, S3, S4, S5, S6 of building B1, a fire alarm system 3, a signaling device 4, and a plurality of fire alarm devices 1 (24 in Figure 1) installed on the exterior walls of building B1. If building B1 has, for example, a roughly rectangular parallelepiped shape as a whole, then four fire alarm devices 1A are installed in the parts of each of its four exterior walls corresponding to the first floor S1, and four fire alarm devices 1B are installed in the parts of each of the four exterior walls corresponding to the second floor S2. Furthermore, four fire alarm devices 1C are installed in the parts of each of the four exterior walls corresponding to the third floor S3, and four fire alarm devices 1D are installed in the parts of each exterior wall corresponding to the fourth floor S4. Furthermore, four fire alarm devices 1E are installed on each of the four exterior walls in the area corresponding to the 5th floor S5, and four fire alarm devices 1F are installed on each of the four exterior walls in the area corresponding to the 6th floor S6. These fire alarm devices 1A, 1B, 1C, 1D, 1E, and 1F will light up or flash when a fire occurs on each floor S1, S2, S3, S4, S5, and S6, respectively, to notify people outside of building B1 of the location of the fire within building B1. Since fire alarm devices 1A, 1B, 1C, 1D, 1E, and 1F are installed on all four exterior walls of building B1, people outside of building B1 can recognize the location of the fire regardless of the direction they are facing building B1. As shown in Figure 2, each of the multiple fire detectors 2 generates a fire detection signal and transmits it to the fire alarm system 3 when it detects the occurrence of a fire F in the floors S1, S2, S3, S4, S5, and S6, which are the areas of fire detection targeted by the building.

[0011] The fire alarm system 3 operates on 100V AC power supplied from, for example, a commercial AC power supply. When the fire detector 2 detects a fire and the system acquires the fire detection signal sent from the fire detector 2, it outputs a transfer signal to the signaling device 4 that corresponds to the fire detector 2 that sent the fire detection signal.

[0012] When a transfer signal is input, the signaling device 4 transmits a fire occurrence notification signal to the fire alarm device 1 corresponding to the input transfer signal, i.e., to the floor S1, S2, S3, S4, S5, S6 where the fire was detected. Here, the fire occurrence notification signal can be a DC voltage signal that is set to a preset first voltage (e.g., 24V) if no transfer signal is input, and to a preset second voltage (e.g., 0V) lower than the first voltage if a transfer signal is input. The signaling device 4 also has an operation unit 41 that is operated by the user to stop the illumination or flashing of the light source 13, described later, by the fire alarm device 1. When the operation unit 41 is operated, the signaling device 4 transmits a stop signal to the fire alarm device 1 that is illuminating or flashing the light source 13.

[0013] As shown in Figure 3, the fire alarm device 1 includes a light source 13, a lighting circuit 12 for lighting or flashing the light source 13, a power supply circuit 11 for converting alternating current power supplied from a commercial power source (AC) to direct current power and supplying it to the lighting circuit, and a battery 15. Here, the light source 13 can be, for example, a lamp equipped with an LED (Light Emitting Diode). The power supply circuit 11 includes a rectifier circuit for rectifying the alternating current supplied from a commercial power source (AC), and a smoothing circuit for smoothing the direct current output from the rectifier circuit. The lighting circuit 12 has a power conversion circuit that boosts or steps down the direct current power input from the power supply circuit 11 and outputs it to the light source 13. Furthermore, the fire alarm device 1 has a lighting control unit 14 that, upon receiving a fire occurrence notification signal transmitted from a signaling device 4, drives the lighting circuit to light up or flash the light source 13. This lighting control unit 14 has an internal timer and has the function of measuring the elapsed time since the lighting or flashing of the light source 13 began. Furthermore, when the lighting control unit 14 receives a fire notification signal transmitted from the signaling device 4, it drives the lighting circuit 12 to start the lighting or flashing of the light source 13. Subsequently, when the lighting control unit 14 determines that a preset notification duration has elapsed, it stops the lighting or flashing of the light source 13. Here, the notification duration is set to, for example, 60 mins. The Fire Service Act stipulates that the notification duration for emergency exit signs installed in high-rise buildings or large underground shopping areas should be 60 mins, as it is said that it takes approximately 60 mins from the time a fire breaks out until firefighters arrive at the scene and complete rescue operations. In addition, when the lighting control unit 14 receives a stop signal transmitted from the signaling device 4, it stops the lighting or flashing of the light source 13.

[0014] Furthermore, the fire alarm device 1 includes a switch unit 16 having a switch SW1 inserted in the power supply path L1 from the power circuit 11 to the lighting circuit 12, and a switch SW2 inserted in the power supply path L2 from the battery 15 to the lighting circuit 12, a voltmeter 17, and a switching unit 18. The switching unit 18 switches the power source to the lighting circuit 12 between the power circuit 11 and the battery 15 by changing the open / closed state of switches SW1 and SW2 of the switch unit 16. The voltmeter 17 measures the output voltage of the power circuit 11 and transmits a detection signal indicating the measured output voltage to the switching unit 18. When the switching unit 18 receives the detection signal transmitted from the voltmeter 17, it determines based on the acquired detection signal that the power supply from the power circuit 11 to the lighting circuit 12 has been cut off, and switches SW1 to the open state and SW2 to the closed state, thereby switching to a state in which DC power is supplied to the lighting circuit 12 from the battery 15.

[0015] Next, the fire alarm processing performed by the fire alarm device 1 according to this embodiment will be explained with reference to Figure 4. First, the lighting control unit 14 determines whether or not it has received a fire occurrence notification signal transmitted from the signal device 4 (step S101). Here, the lighting control unit 14 repeatedly executes the process in step S101 as long as it determines that it has not received a fire occurrence notification signal (step S101: No). On the other hand, if the lighting control unit 14 determines that it has received a fire occurrence notification signal (step S101: Yes), the switching unit 18 determines whether or not the DC voltage V supplied from the power supply circuit 11, indicated by the detection signal transmitted from the voltmeter 17, is equal to or greater than a preset voltage threshold Vth (step S102). Here, if the switching unit 18 determines that the voltage V is equal to or greater than the voltage threshold Vth (step S102: Yes), it closes switch SW1 and opens switch SW2 (step S103), so that power is supplied from the power supply circuit 11 to the lighting circuit 12. On the other hand, when the switching unit 18 determines that the voltage V is less than the voltage threshold Vth (step S102: No), it opens switch SW1 and closes switch SW2 (step S104), so that power is supplied from the battery 15 to the lighting circuit 12.

[0016] Subsequently, the lighting control unit 14 drives the lighting circuit 12 to light or blink the light source 13 (step S105). After that, the lighting control unit 14 determines whether it has acquired a stop signal transmitted from the signal device 4 (step S106). Here, when the lighting control unit 14 determines that it has acquired the stop signal (step S106: Yes), the process of step S108 described later is executed. On the other hand, when the lighting control unit 14 determines that it has not acquired the stop signal (step S106: No), it determines whether the aforementioned notification duration has elapsed (step S107). Here, when the lighting control unit 14 determines that the notification duration has not yet elapsed (step S107: No), the process of step S102 is executed again. On the other hand, when the lighting control unit 14 determines that the notification duration has elapsed (step S107: Yes), it stops the lighting circuit 12 to turn off the light source 13 (step S108). After that, the process of step S101 is executed again.

[0017] As described above, according to the fire occurrence location notification system according to the present embodiment, the plurality of fire notification devices 1 are respectively installed at positions corresponding to the plurality of floors S1, S2, S3, S4, S5, S6 on the outer wall of the building B1, and the light source 13 is lit or blinked according to the floors S1, S2, S3, S4, S5, S6 where the fire F is detected by the fire detector 2. Thereby, when a fire occurs inside the building B1, a person outside the building B1 can grasp the floors S1, S2, S3, S4, S5, S6 where the fire is occurring inside the building B1 from the position of the fire notification device 1 in which the light source 13 is lit or blinked among the fire notification devices 1 installed on the outer wall of the building B1. Therefore, it is possible to quickly notify a person outside the building B1 of the fire occurrence location inside the building B1.

For example, as shown in FIG. 5, when a plurality of fire detectors 2002 (2002A, 2002B, 2002C, 2002D, 2002E, 2002F) detect the occurrence of a fire F on the floors S1, S2, S3, S4, S5, S6 to be detected for fire by each of them, they may generate a fire occurrence notification signal and directly transmit it to the fire alarm device 1.

[0019] As described above, the embodiments and modification examples of the present invention have been explained. However, the present invention is not limited to these.
