Introduction

Fire is one of the most terrifying disasters in homes and buildings. A fire outbreak can result in loss of property and danger to human life, and requires a great deal of effort for subsequent restoration and recovery. Therefore, early detection and rapid response to fires are critical factors. In this article, we will explore disaster prevention equipment that supports early detection in the event of a fire.

 

1. Smoke detector

A smoke detector is a device that detects smoke in the event of a fire. Smoke occurs in the early stages of a fire, so smoke detectors contribute to early detection. Common smoke detectors include optical, ionization, and thermal sensors. If these detectors detect an abnormal increase in smoke, they will issue an alarm, alerting people to the presence of a fire.

There are several types of smoke detectors, but the main types are:

1-1 Optical smoke detector

Optical smoke detectors are the most common type and are commonly used in residential spaces such as homes and offices. There is a light source and a light sensor inside, and the sensor is activated when smoke blocks the light. Optical smoke detectors are capable of detecting early stage fires, which are typically of combustible material.

 

1-2 Ionization smoke detector

Ionization smoke detectors detect smoke by detecting ionized particles in the air. Inside, there is a radiation source and an ionization chamber, and when smoke enters, the radiation flow changes, activating the detector. Ionization smoke detectors are capable of detecting minute particles produced by the generation of combustible materials.

 

1-3 Thermal smoke detector

Thermal smoke detectors detect fires by detecting changes in ambient temperature. There is a temperature sensing element inside, and if it detects a sudden rise above the preset temperature, the sensor will be activated. Thermal smoke detectors are useful in fires and hot areas where smoke is not present.

By detecting smoke in the early stages of a fire, these smoke detectors provide an early warning, prompting people to evacuate or take countermeasures. Smoke detectors are always on and will alert you through built-in audible alarms and flashing lights when smoke is detected. Also, some advanced smoke detectors offer a variety of features, such as wireless connectivity and integration with smart home systems.

 

2. Fire alarm panel

2-1 Fire monitoring and detection

Fire alarm panels receive information from smoke detectors, heat detectors, and other sensors in the building to monitor the presence of fire. Abnormal smoke and high temperature detection enables early detection of fires.

 

2-2 Alarm transmission

A fire alarm panel will give the appropriate alarm if a fire is detected. People are notified of a fire, usually through an audible alarm, flashing lights, or an emergency broadcast system. This will allow residents and users in the building to evacuate quickly.

 

2-3 Locating and displaying

Fire alarm panels have the ability to identify specific locations and areas where fires have occurred. Each smoke detector and sensor is installed in a specific location, and the display and instructions on the panel make it possible to understand in which area the fire is occurring.

 

2-4 Reporting device

Some fire alarm panels have the ability to automatically notify the fire department or emergency services when a fire is detected. This allows the fire department to arrive quickly and respond quickly.

 

2-5 Backup power

A stable power supply is usually important for fire alarm panels. Some systems have battery backup so that they can continue to operate normally in the event of a power outage or power problem.

 

3. Automatic fire extinguishing system

3-1 Automatic sprinkler system

Automatic sprinkler systems detect fires in buildings and extinguish them by releasing water from sprinkler heads. The sprinkler head automatically activates when high temperature or smoke is detected to prevent the spread of fire. Sprinkler systems are widely used in a wide range of buildings and facilities and are highly effective and reliable.

 

3-2 Gas fire extinguishing system

Gas extinguishing systems use specific gases (e.g. Halon, CO2 , FM-200 , etc.) to extinguish fires. These gases deplete oxygen, cool the fire, and suppress reactants to prevent the spread of the fire. Gas fire suppression systems are widely used where electronic equipment and valuable assets are present.

 

3-3 Foam extinguishing system

Foam extinguishing systems use special extinguishing agents to extinguish fires. The system combines a blowing agent with water and releases a foamy mixture onto the fire site. The foam cools the fire and cuts off the oxygen supply to extinguish the fire. Especially used where flammable liquids and chemicals are present.

 

3-4 water spray system

Water spray systems use high pressure water to extinguish fires. A fine mist of water emitted from the spray head cools the fire and dilutes the burning material to extinguish the fire. Water spray systems are used especially in petrochemical facilities and warehouses.

 

 

4. Temperature monitoring system

4-1 Temperature sensor

Temperature monitoring systems use temperature sensors or temperature probes to measure temperature. Sensors are placed at different locations in the building to monitor temperature changes and trends in real time. Sensor types include thermistors, thermocouples, and infrared sensors.

 

4-2 Data collection and monitoring

Temperature monitoring systems transmit data collected from sensors to a central monitoring system. This monitoring system can visualize temperature data and monitor it in real time. It also stores data logs and histories for analysis and reporting as needed.

 

4-3 Alarms and notifications

The temperature monitoring system will issue alarms and notifications when it detects an abnormal temperature rise above the preset temperature range. This will alert relevant parties to take appropriate action. Notification methods include audio alarms, emails, text messages, and smartphone apps.

 

4-4 Remote monitoring and control

Some temperature monitoring systems have remote access capabilities. This allows stakeholders to remotely monitor temperature data and make temperature controls and adjustments as needed. It can also be monitored and controlled via the Internet.

 

4-5 Reports and analysis

Temperature monitoring systems provide the ability to record and analyze temperature data. This allows you to understand temperature fluctuations and trends and predict future problems. In addition, data reporting and storage are also important functions to meet legal and regulatory requirements.

 

 

5. Radio communication system

5-1 Wireless local area network

A wireless local area network is a wireless communication technology that allows devices such as computers and mobile devices to connect to the Internet or local networks through wireless LAN routers. It is mainly used in homes, offices and public places, and is also commonly known as Wi-Fi .

 

5-2 Mobile communication system

Mobile communication systems are wireless communication technologies for sending and receiving voice and data using mobile devices such as mobile phones and smart phones. Typical mobile communication systems include GSM ( Global System for Mobile Communications ), CDMA ( Code Division Multiple Access ), and LTE ( Long-Term Evolution ).

 

5-3 Bluetooth

Bluetooth is a wireless communication technology intended for short-range data communication and connection between devices. It is mainly used to connect peripherals such as headsets, speakers, keyboards and mice. You can also send and receive files and share data between devices using a smartphone or tablet equipped with Bluetooth .

 

5-4 Wireless Sensor Network ( WSN )

WSN is a system in which multiple sensor nodes collect and transmit information using wireless communication and communicate with each other within the network. It is used in various applications such as environmental monitoring, disaster prevention systems, and industrial control.

 

5-5 Satellite communication

Satellite communication is a radio communication system in which information is transmitted from a specific region of the earth to a satellite, which relays the information to another region or receiving station on the earth. Satellite communications are widely used in locations with limited communications infrastructure, such as remote areas and over the sea.

 

6. What can be saved by early detection

Fire is a dangerous disaster that causes serious damage to human life and property due to its speed and destructive power. However, early detection of fire plays an important role in rescuing victims and minimizing damage. Let's explore what early detection of a fire can save.

 

6-1 Saving lives

In the event of a fire, the smoke and the force of the fire limit the time for victims to evacuate. However, when a fire breaks out, smoke detectors and fire alarms are activated early, and people can sense the danger and start evacuating to a safe place. Early detection saves precious time in saving lives.

 

6-2 Property protection

Fires can cause extensive damage to buildings and property. However, when a fire breaks out, the fire alarm panel and temperature monitoring system are activated early, and the fire department and related parties are automatically notified, and the fire extinguishing activity can be started quickly. Early reporting and fighting the fire increases the chances of further damage being prevented and property being protected.

 

6-3 Continuation of business

In the event of a fire, businesses and organizations can suffer losses such as disruption of production and operations, loss of data, and loss of trust with customers and business partners. However, if a fire breaks out, a fire alarm will be activated early, and the concerned parties will be notified, enabling a quick response. Early response can prevent fires from spreading and causing serious damage and ensure business continuity.

 

7. Neighborhood and community safety

A fire can affect not only a single building, but also surrounding buildings and communities. However, early detection of a fire can alert local residents and related organizations, enabling prompt response and ensuring the safety of the surrounding area. Early detection and reporting of fires is an important factor in keeping neighbors and entire communities safe.

 

Early detection of fire is essential to protect people's lives and property. Properly installing disaster prevention devices such as smoke detectors, fire alarms, and fire alarm panels, and conducting regular inspections and maintenance, will enable early detection and prompt response to fires. This will help minimize damage and protect people's safety and peace of mind.
