FIRE ALARM SYSTEM

Types of Fire Alarm Systems:

There are different types of fire alarm- systems like:

Conventional Fire Alarm

In a conventional alarm system, there are many call points and detectors. There are different zones in the call points for dividing the building into small divisions, to exactly detect the area and reason for fire, and to overcome it easily. Any sort of bell or sound is connected with the control panel for producing sounds. Every zone contains either light, texts, or both. The whole system is controlled by the main unit.

Addressable Alarm system:

Addressable alarm system and conventional alarm system works similarly. The only is that, there is a specific ‘address’ for every detector in t addressable alarm system. This feature helps in detecting the exact call point that triggers the alarm. The formation of the detection circuit is a loop like, in every loop even 99 devices can be connected. There are different sections for dividing the loops so that if a fault occurs, only a limited area gets damaged and the rest of the area keeps on working properly.

Wireless Fire Alarm, System:

As the name indicates, the wireless alarm system is free from the hassle of wires. All the components are interconnected with the help of radio communications. There is a control panel that operates the whole system. .

Fire alarm system components

Fire alarm systems typically include the following components:

• Fire Alarm Control Panel (FACP):This is the central hub of the fire alarm system. The FACP receives signals from various detectors and, based on pre-programmed settings, initiates an alarm or other response.
• Smoke Detectors: These are sensors that detect smoke particles in the air. There are several types of smoke detectors, including ionization smoke detectors and photoelectric smoke detectors.
• Heat Detectors:These sensors detect changes in temperature that could indicate a fire. There are two types of heat detectors: o Fixed temperature Detectors and o Rate-of-rise Detectors.
• Sprinklers: These are devices that automatically spray water when they detect heat. Sprinklers are designed to control the spread of fire and protect people and property.
• Manual Pull Stations:These are devices that allow people to manually trigger an alarm. They are typically located near exits and other high-traffic areas.
• Notification Devices: These devices provide an audible and/or visual alert to occupants of the building that a fire has been detected. Examples include horns, strobe lights, and voice alarms.
• Control Modules:These devices provide a way to integrate other systems, such as elevators or HVAC systems, with the fire alarm system. They can also provide additional programming and control capabilities for the FACP.
• Power Supplies:These devices provide electrical power to the fire alarm system. They can be either battery-powered or connected to the buildingÂ’s electrical system.
• Communication Devices:These devices allow the fire alarm system to communicate with other systems, such as emergency services or building management systems. They can also provide remote monitoring and control

Fire Alarm System Conclusion:

The fire alarm systems are used to warn people about a fire incident or any other emergency situation. This warning can easily save the lives of people, the buildings, and the important assets and documents kept in those buildings. We have seen that the fire alarm systems have different parts like detectors. There are various types of detectors used in fire alarm systems like heat detectors, smoke detectors, carbon monoxide detectors multi-sensor detectors, and manual call points. Then the fire alarm systems also have three different types including conventional fire alarm systems, addressable fire alarm systems, intelligent fire alarm systems, and wireless fire alarm systems.
