Description

[Detailed Description of the Invention] The present invention integrates a fire detection function and an alarm sound generation function, and can operate independently, detecting a fire and emitting an alarm sound to prevent the occurrence of a fire. This relates to a fire alarm system that uses sound to notify the surrounding area of a location. It is effective as a fire alarm in small and medium-sized businesses, multi-tenant buildings, apartments, and general residences.

It can also be used in conjunction with a fire alarm system or as a sensing part to notify people near the location of a fire.

Traditional fire alarm systems are large, complex and expensive. It is complicated to operate, does not function well and often causes large fires. It is unsuitable for small and medium-sized businesses, multi-tenant buildings, apartments, and general residences, and fire alarms suitable for such places have not been manufactured.

Especially in the case of a house fire, there are people in the house. In addition, even though there are people in neighboring houses, there are many cases where the fire is not detected because people are sleeping and the fire becomes a major fire, resulting in fatalities. Traditional fire alarm systems have become larger in scale, centrally managed,
It has become more complex. Further, the fire detection part and the alarm sound generation part are usually located in different places. For these reasons, fire alarms are far removed from the principle of fire alarms, which is to notify nearby people of the occurrence and location of a fire at an early stage. Proper operation may not be carried out and may add to the chaos at the fireground. For example, if an alarm is sounded throughout the entire building, without the necessary and sufficient instructions and guidance from the person in the central control room, it will be difficult to know which direction to evacuate to, causing confusion.

Also, since the location where the alarm sound is generated is different from the location where the fire is detected,
If there is smoke, it is difficult to find the location of the fire, and even a slight delay in extinguishing the fire may result in a large fire.

The present invention integrates a fire detection part and an alarm sound generation part,
In principle, they have a built-in power source such as a power source, and can operate independently. They detect the occurrence of a fire, emit an alarm, and audibly notify the surrounding area of the occurrence and location of the fire. It can be used independently, incorporated into a ceiling-mounted lighting system, or combined with a fire alarm system to function as a fire detection unit that generates an alarm sound.

Features operate independently and automatically. Highly reliable as it does not involve human manipulation. Easy to install as no wiring is required. Cheap price. An alarm can be emitted at the location of the fire and the surrounding area can be reliably notified, making it easier to extinguish the fire in the early stages.

The structure mainly consists of a fire detection section, an alarm sound generation section, and a power source section.

The fire detection unit is conventionally used, and often includes a heat sensor such as a temperature-sensitive reed switch, a smoke sensor, an ion sensor, etc., either alone or in combination. Synthetic resins with an appropriate softening temperature can also be used as heat-sensing sensors. Provide a signal output terminal to the outside as necessary.

The alarm sound generator is constructed of a small bell-type, buzzer-type, etc. device that can generate a loud sound. If high-pressure gas is used as the power source, it is best to use a whistle type. If necessary, an intermittent sound generation circuit is incorporated to create a structure that generates intermittent sound.

In an electric system, the power source section is constructed by using a battery such as a dry cell battery or a rechargeable battery or an AC-DC converter alone or in combination as a power source, and is structured to operate reliably even during a power outage. The power supply and peripheral circuits should be insulated with heat insulating materials so that they can maintain their functionality for the time necessary for initial fire extinguishment and evacuation. Other power sources include springs such as mainsprings and high-pressure gas.

Although it is good for improving heat resistance, it is not suitable for increasing the pronunciation time. If a fire extinguishing gas such as halon gas is used as the high pressure gas, it can have a fire extinguishing function.

As an example, an example of a bell-shaped dry cell battery will be shown.

The switch on a commercially available battery-powered call bell has been replaced with a temperature-sensitive reed switch, with a structure that allows it to be fixed by hanging it from the ceiling, and the battery box has an insulated structure.
