[0009] A fire occurrence location notification system according to an embodiment of the present invention will be described below with reference to the drawings. The fire occurrence location notification system according to the embodiment includes a fire detector installed in each of a plurality of areas in a building, and a plurality of fire alarm devices each having a light source and installed at a position corresponding to each of the plurality of areas on an exterior wall of the building, and each turning on or blinking the light source in response to at least one area in which a fire is detected by the fire detector.

[0010] As shown in Fig. 1, the fire occurrence location notification system according to the present embodiment includes a plurality of fire detectors 2 (six in Fig. 1) installed on each floor S1, S2, S3, S4, S5, and S6 of a building B1, a fire alarm system 3, a signal device 4, and a plurality of fire alarm devices 1 (24 in Fig. 1) installed on the exterior walls of the building B1. When the building B1 has a shape of a substantially rectangular parallelepiped as a whole, for example, four fire alarm devices 1A are installed on the four exterior walls in a portion corresponding to the first floor S1, and four fire alarm devices 1B are installed on the four exterior walls in a portion corresponding to the second floor S2. In addition, four fire alarm devices 1C are installed on the four exterior walls in a portion corresponding to the third floor S3, and four fire alarm devices 1D are installed on the four exterior walls in a portion corresponding to the fourth floor S4. Furthermore, four fire alarm devices 1E are installed on the four exterior walls in the portion corresponding to the fifth floor S5, and four fire alarm devices 1F are installed on the four exterior walls in the portion corresponding to the sixth floor S6. These fire alarm devices 1A, 1B, 1C, 1D, 1E, and 1F light up or flash when a fire occurs on each of the floors S1, S2, S3, S4, S5, and S6, respectively, to notify people outside the building B1 of the location of the fire in the building B1. And, since the fire alarm devices 1A, 1B, 1C, 1D, 1E, and 1F are installed on all four exterior walls of the building B1, people outside the building B1 can recognize the location of the fire regardless of the direction they face the building B1. As shown in Figure 2, when multiple fire detectors 2 detect the occurrence of a fire F on floors S1, S2, S3, S4, S5, and S6, which are the areas subject to fire detection by the respective fire detectors, they generate a fire detection signal and transmit it to a fire alarm system 3.

[0011] The fire alarm system 3 operates, for example, on 100V AC power supplied from a commercial power source AC that supplies AC power, and when it acquires a fire detection signal sent from the fire detector 2 when the fire detector 2 detects a fire, it outputs to the signal device 4 a report signal corresponding to the fire detector 2 that sent the fire detection signal.

[0012] When the signaling signal is input, the signaling device 4 transmits a fire occurrence notification signal to the fire alarm device 1 corresponding to the inputted signaling signal, i.e., corresponding to the floors S1, S2, S3, S4, S5, and S6 where a fire has been detected. Here, the fire occurrence notification signal may be a DC voltage signal that is set to a preset first voltage (e.g., 24 V) when the signaling signal is not inputted, and is set to a preset second voltage (e.g., 0 V) ​​lower than the first voltage when the signaling signal is inputted. The signaling device 4 also has an operation unit 41 that is operated by a user when stopping the lighting or blinking of the light source 13 described below 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 lighting or blinking the light source 13.

[0013] As shown in FIG. 3, the fire alarm device 1 includes a light source 13, a lighting circuit 12 that lights or blinks the light source 13, a power supply circuit 11 that converts AC power supplied from a commercial power supply AC into DC power and supplies the DC power to the lighting circuit, and a battery 15. Here, as the light source 13, for example, a lamp equipped with an LED (Light Emitting Diode) can be adopted. The power supply circuit 11 includes, for example, a rectifier circuit that rectifies AC power supplied from a commercial power supply AC that is an AC power supply, and a smoothing circuit that smoothes the DC power output from the rectifier circuit. The lighting circuit 12 includes a power conversion circuit that boosts or lowers the DC power input from the power supply circuit 11 and outputs it to the light source 13. In addition, the fire alarm device 1 includes a lighting control unit 14 that drives the lighting circuit to light or blink the light source 13 when it acquires a fire occurrence notification signal transmitted from the signal device 4. The lighting control unit 14 includes an internal timer and has a function of measuring the elapsed time since the light source 13 started to light or blink. Furthermore, when the lighting control unit 14 receives a fire occurrence notification signal transmitted from the signal device 4, it drives the lighting circuit 12 to start lighting or blinking the light source 13. After that, when the lighting control unit 14 determines that a preset notification duration has elapsed, it stops lighting or blinking the light source 13. Here, the notification duration is set to, for example, 60 minutes. The Fire Service Act requires that the notification duration be 60 minutes for emergency lights installed in high-rise buildings or large underground shopping malls, and it is said that the time from the occurrence of a fire until the time when a fire brigade rushes to the fire site and completes rescue activities is approximately 60 minutes, so it is preferable to set the notification duration to 60 minutes. Furthermore, when the lighting control unit 14 receives a stop signal transmitted from the signal device 4, it stops lighting or blinking the light source 13.

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

[0015] Next, the fire alarm process executed by the fire alarm device 1 according to the present embodiment will be described with reference to FIG. 4. First, the lighting control unit 14 judges whether or not it has acquired a fire occurrence notification signal transmitted from the signal device 4 (step S101). Here, the lighting control unit 14 repeatedly executes the process of step S101 as long as it judges that it has not acquired a fire occurrence notification signal (step S101: No). On the other hand, when the lighting control unit 14 judges that it has acquired a fire occurrence notification signal (step S101: Yes), the switching unit 18 judges whether or not the direct current voltage V supplied from the power supply circuit 11 indicated by the detection signal transmitted from the voltmeter 17 is equal to or higher than the preset voltage threshold value Vth (step S102). Here, when the switching unit 18 judges that the voltage V is equal to or higher than the voltage threshold value Vth (step S102: Yes), it closes the switch SW1 and opens the 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 the switch SW1 and closes the switch SW2 (step S104) to allow power to be supplied from the battery 15 to the lighting circuit 12.

[0016] Next, 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 judges whether or not a stop signal transmitted from the signal device 4 has been acquired (step S106). Here, if the lighting control unit 14 judges that a stop signal has been acquired (step S106: Yes), the processing of step S108 described later is executed. On the other hand, if the lighting control unit 14 judges that a stop signal has not been acquired (step S106: No), the processing of step S107 is executed again. Here, if the lighting control unit 14 judges that the notification duration has not yet elapsed (step S107: No), the processing of step S102 is executed again. On the other hand, if the lighting control unit 14 judges that the notification duration has elapsed (step S107: Yes), the lighting control unit 14 stops the lighting circuit 12 and turns off the light source 13 (step S108). Then, the processing of step S101 is executed again.

[0017] As described above, according to the fire occurrence location notification system of the present embodiment, a plurality of fire alarm devices 1 are installed at positions corresponding to a plurality of floors S1, S2, S3, S4, S5, and S6 on the outer wall of the building B1, and the light source 13 is turned on or blinked according to the floor S1, S2, S3, S4, S5, and S6 on which the fire F is detected by the fire detector 2. In this way, when a fire occurs in the building B1, a person outside the building B1 can know the floor S1, S2, S3, S4, S5, and S6 on which the fire occurs in the building B1 from the position of the fire alarm device 1 that is turning on or blinking the light source 13 among the fire alarm devices 1 installed on the outer wall of the building B1. Therefore, the location of the fire occurrence in the building B1 can be quickly notified to a person outside the building B1.

[0018] Although the embodiment of the present invention has been described above, the present invention is not limited to the configuration of the above-mentioned embodiment. For example, as shown in Fig. 5, a plurality of fire detectors 2002 (2002A, 2002B, 2002C, 2002D, 2002E, 2002F) may generate a fire occurrence notification signal and transmit it directly to the fire alarm device 1 when detecting an occurrence of a fire F on floors S1, S2, S3, S4, S5, and S6 that are the fire detection targets of the respective fire detectors.

[0019] Although the embodiments and modifications of the present invention have been described above, the present invention is not limited to these. The present invention includes appropriate combinations of the embodiments and modifications, and appropriate modifications thereto. [Industrial Applicability]
