Description

  The present invention relates to an alarm device that issues an alarm with light such as flash emission when a fire occurs.

  In the case where a person who should evacuate when an emergency occurs has a hearing impairment, it is desired to spread an alarm device that works on a sense other than hearing such as light to notify the emergency. When alarming with light, it is necessary to generate strong light that can be seen through smoke in the event of a fire (Reference: Report of the 1970 Fire Research Institute “Visibility in smoke (I)”, 1971 Proceedings of the Japan Fire Society A series of research papers by Tadahisa Jin, such as “About the line-of-sight distance in smoke”). An optical alarm device that emits light intermittently using an electronic flash typified by a strobe (registered trademark) that emits intense flash light, a high-intensity LED lamp, or the like as a light source is known (Patent Literature). 1 and 2).

  On the other hand, in buildings with emergency broadcasting equipment linked to automatic fire alarm equipment, “detector alarm broadcasting” that notifies when a fire detector is activated, and when a fire is determined, a fire occurs. Voice messages are used to announce “fire broadcasts” that prompt evacuation and “non-fire broadcasts” that notify the fire detector when it is confirmed that the fire detector is not triggered by a fire (for example, (See Patent Document 3). By performing such broadcasting, the residents can grasp the situation correctly and promptly, and can take appropriate measures such as evacuation without causing unnecessary panic.

The light alarm device 1 is connected to the power supply device 6 through the alarm signal line 10 and further connected to the fire receiver 2. In addition, the fire receiver 2 is connected to a plurality of smoke detectors 3 and a transmitter 4 by a detection signal line 5. Furthermore, the fire receiver 2 is connected to the emergency telephone base unit 9 and is connected to the emergency telephone handset 7 via the emergency telephone line 8. The display means 11 a is a display device such as a liquid crystal display device, and is connected to the light alarm device 1. Further, the display means 11 b is connected to the power supply device 6. The display means 11a and 11b need not be provided, and the case of providing them will be described later.

  When smoke due to fire is detected, the smoke detector 3 sends a fire detection signal, and the fire receiver 2 receives the fire detection signal through the detection signal line 5. When the transmitter 4 is operated by a person who has found a fire, the transmitter signal is transmitted from the transmitter 4 to the fire receiver 2 and when the emergency telephone handset 7 is operated, the emergency telephone base unit. From 9, an emergency telephone fire signal is transmitted to the fire receiver 2. The fire receiver 2 includes a fire determination switch (not shown) that is operated when the operator determines that a fire has occurred, and a non-fire switch (not shown) that is operated when it is confirmed that there is no fire (non-fire). )have.

  When the fire receiver 2 receives the fire detection signal and determines that the fire is detected by the fire determination function such as the storage function, the fire receiver 2 receives the fire detection signal from two or more of the categories corresponding to the monitoring area. When a signal is received, when an emergency telephone fire signal is received, when a fire determination switch is operated, a fire alarm signal as fire alarm notification information is transmitted to the light alarm device 1 via the power supply device 6. In addition, the fire receiver 2 receives a detector notification signal as notification information of the detector notification when a fire detection signal is received, and a non-fire signal as non-fire notification information when the non-fire switch is operated. , Respectively, to the light alarm device 1 through the power supply device 6.

  The fire alarm signal, the sensor alarm signal, and the non-fire signal are transmitted to the optical alarm device 1 through the alarm signal line 10, and each signal indicates or is different depending on the notification information included in each signal. The light emitting element of the light alarm device 1 is caused to emit light in a light emitting mode. Based on the signal from the fire receiver 2, the power supply device 6 sends a fire alarm signal, a sensor alarm signal, and a non-fire signal to the light alarm device 1 and supplies power required to drive the light alarm device 1. However, it has a reserve power source composed of a secondary battery for supplying power in the event of a power failure.

  FIG. 2 shows the internal configuration of the light alarm device 1. The light emitting element 101 is driven by the light emission driving means 102. When the light emitting element 101 is an LED, the light emission driving means 102 is a current driving means, and when the light emitting element 101 is a space discharge type light emitting element that requires a high voltage power source such as a xenon tube, the light emission driving means 102 has a booster circuit. A signal such as a fire alarm signal from the fire receiver 2 is input from the alarm signal line 10 to the control means 104 via the receiving means 105. Further, a sound output unit 103 may be provided, and a buzzer sound or a voice message may be output under the control of the control unit 104. The sound output means 103 may output a loud sound buzzer sound at the time of a fire alarm, or may output a voice message as described later, as a district sound device of an automatic fire alarm facility.

  Next, the light emission pattern of the light alarm device 1 corresponding to each notification information in Example 1 will be described with reference to FIG. 3A is a light emission pattern when the notification information is a sensor alert, FIG. 3B is a light emission pattern when the notification information is a fire alarm, and FIG. 3C is a case where the notification information is non-fire. A light emission pattern is shown. The horizontal axis represents time, which is shown to flow from left to right in the figure. The vertical axis represents the emission intensity. When the smoke detector 3 in FIG. 1 detects smoke or the like and sends a sensor signal, the fire receiver 2 receives the sensor signal and starts a fire judgment operation such as a storage function, and supplies the sensor notification signal as a power source. Send to device 6. The sensor alarm signal is received by the receiving means 105 of each light alarm device 1 via the power supply device 6 and the alarm signal line 10 and transmitted to the control means 104. The control means 104 sends an operation signal to the light emission drive means 102, and causes the light emitting element 101 to intermittently flash with the light emission pattern of FIG. In the light emission pattern of FIG. 3A, white light emits light intermittently at a brightness that is darker than that at the time of a fire alarm, for example, a moderate brightness, thereby notifying a detector.

  On the other hand, (1) When the transmitter 4 is operated, (2) When the emergency telephone handset 7 is operated, (3) The second fire detector in the monitoring area separated from the activated smoke detector 3 , Ie when it is determined that the fire has spread (when an extended fire has occurred), (4) when an operator who has determined that a fire has operated the fire determination switch, (5) a fire receiver 2 is determined to be a fire by a fire determination operation such as a storage function, or if a non-fire switch has not been operated and a predetermined time has elapsed since it was determined to be a fire, it is determined that a fire has occurred. Send fire alarm signal from 2. This fire alarm signal is sent to each optical alarm device 1 via the power supply device 6. Upon receiving the fire alarm signal, the control means 104 of the light alarm device 1 transmits an operation signal to the light emission drive means 102, and causes the light emitting element 101 to emit light in the light emission pattern of FIG. In the light emission pattern of FIG. 3B, a fire alarm is notified by performing flash light emission that intermittently emits flash light with strong white light. The emitted light intensity is stronger than the sensor notification of FIG. 3A, and the light emission period is shorter than the sensor notification.

  When the operator confirms that the operation of the fire detector is not caused by a fire (non-fire report), the non-fire notification is made by operating the non-fire switch of the fire receiver 2. A non-fire signal is sent from the fire receiver 2 in which the non-fire switch is operated to each light alarm device 1 via the power supply device 6 and the alarm signal line 10. The control means 104 of the light alarm device 1 that has received the non-fire signal transmits an operation signal to the light emission drive means 102, and causes the light emitting element 101 to emit light intermittently with the light emission pattern of FIG. To do. In the light emission pattern of FIG. 3C, the light emission intensity is gradually changed from a slightly strong light emission pulse to a weak light emission pulse, and the light emission period is gradually increased.

  As described above, a hearing-impaired person can recognize the notification information by causing the light emitting element to emit light in a specific light emission mode according to the sensor notification, the fire alarm, and the non-fire notification information. . In Example 1, the light emitting element emits light in a specific light emission mode that differs depending on the notification information depending on the combination of the light emission intensity and the light emission period. It is desirable that what light emission mode corresponds to what notification information is a light emission mode that is easy to understand intuitively, and it is desirable that the light emission mode is well known in advance. In particular, if the information is made known to a hearing impaired person in advance, the notification information can be transmitted more accurately.

  In the case of sensor notification or non-fire, a light emission mode using continuous light emission for a certain period other than instantaneous light emission such as flash light emission may be used. FIG. 4 is a diagram illustrating a light emission pattern of the light alarm device 1 corresponding to each notification information according to the second embodiment. 4A is a light emission pattern when the notification information is a sensor alert, FIG. 4B is a light emission pattern when the notification information is a fire alarm, and FIG. 4C is a case where the notification information is non-fire.

In Example 2, the light emitting element emits light in a specific light emission mode that differs depending on the notification information depending on the combination of the light emission intensity and the light emission period.

  For example, when the light alarm device 1 receives a sensor alarm signal, as shown in FIG. 4A, it is darker than a fire alarm, and is repeatedly turned on and off with a certain level of brightness. Is notified. When the light alarm device 1 receives a fire alarm signal, the flash alarm is emitted intermittently by a strong flash as shown in FIG. In addition, when the light alarm device 1 receives a non-fire signal, the light emission that gradually becomes darker than the time of the fire alarm is repeatedly emitted at a longer cycle than the time of the fire alarm as shown in FIG. To notify non-fire. In the second embodiment, when the notification information is a sensor alarm or non-fire, since a large amount of light emission is not required as in the case of a fire alarm, another light emitting element (in addition to the fire alarm light emitting element 101 ( (Not shown) may be provided so that a sensor alarm or non-fire may be reported.

  The light emitted by the light alarm device 1 can have a different emission color depending on the notification information. FIG. 5 is a diagram for explaining a light emission pattern of the light alarm device 1 corresponding to each notification information according to the third embodiment. Fig. 5 (a) shows a light emission pattern when the notification information is a detector alarm, Fig. 5 (b) shows a light emission pattern when the notification information is a fire alarm, and Fig. 5 (c) shows a case where the notification information is non-fire. It is a light emission pattern. In FIG. 5, Y represents yellow, W represents white, R represents red, and B represents blue. 3 and 4, the horizontal axis represents time, and the vertical axis represents emission intensity. In Example 3, the light emitting element emits light in a specific light emission mode that differs depending on the notification information depending on the combination of the light emission intensity, the light emission period, and the light emission color.

When the light alarm device 1 receives a detector alarm signal, it is detected by repeatedly turning on and off yellow (Y) with a certain level of brightness, which is darker than at the time of a fire alarm, as shown in FIG. 5 (a). Announces device alerts. The luminescent color at this time is preferably a different luminescent color so that it can be clearly distinguished from that at the time of a fire alarm, and is not limited to yellow (Y), but red (R), orange (Or), etc. The emission color may be different from that at the time of non-fire notification, which will be described later, or may be kept on without being turned off. When the light alarm device 1 receives the fire alarm signal, the flash alarm is emitted intermittently by strong white light (W) as shown in FIG. In addition, when the light alarm device 1 receives a non-fire signal, as shown in FIG. 5C, the light emission is turned off after the light emission is changed to red (R), yellow (Y), and blue (B). A non-fire is notified with a light emission pattern that repeats at a longer cycle than at the time of a fire alarm. The emission color at this time may be a single color such as blue (B) or green (G) other than the warning color, or may be kept on without being turned off.
