Description

  The present invention relates to an optical alarm device that notifies the occurrence of a fire by flashing light when a fire signal is received from a receiver.

  Conventionally, in buildings such as office buildings, store buildings, hospitals, hotels, etc., an automatic fire alarm system has been used as an alarm system for monitoring the fire and notifying people in the building when a fire occurs. Is installed. In such an automatic fire alarm system, it is common to notify the occurrence of a fire by sound such as a buzzer, a bell, and a message. In addition to this sound notification, display notification using an LED, a red lamp, or the like is also performed as appropriate.

  By the way, in recent years, there has also been proposed an alarm system for notifying the occurrence of a fire by blinking high-luminance white light (flash light) having high visibility along with sound (for example, see Patent Documents 1 to 3). . According to such an alarm system, since the occurrence of a fire is notified not only by sound but also by flashing of strong light, for example, a hearing-impaired person can recognize the occurrence of a disaster early and reliably.

  A wireless alarm system has also been proposed in order to reduce the labor and cost of wiring (for example, see Patent Document 4). The wireless alarm system outputs a fire signal to the repeater via the electrical circuit and receives an alarm command signal (control message) from the repeater when the fire alarm is received by the fire receiver. The light alarm device drives the light emitting unit to emit light after a predetermined delay time Δt after receiving the alarm command signal, and performs synchronous light emission in which the plurality of light alarm devices repeat light emission at a predetermined period T. For light alarm devices installed in places where radio waves do not reach, a radio wave repeater is provided in the middle to relay the alarm command signal, and the same as the light alarm device already emitting light at the relay destination light alarm device Synchronous light emission that repeats light emission at period T is performed.

  In the case of a wireless alarm system, in the event of a fire, the multiple alarm devices are flashed in order from the fire occurrence location to the emergency exit to move away from the fire occurrence location toward the emergency exit. So as to visually induce evacuation.
