Design and implementation of fire alarm systems
Fire alarm systems are among the most important safety equipment that help protect people and property against fire hazards. These systems, by using advanced technologies, quickly and automatically notify any type of fire in the environment.
One of the prominent features of fire alarm systems is speed and accuracy in fire detection. These systems have the ability to detect fire caused by fire, smoke, or temperature rise and announce immediately, this is considered as a vital factor in saving people and property.
Fire alarm systems are active continuously throughout the day and night. This increases the confidence of people in the environment, because any error or incident is immediately detected by the system and reported directly to the control centers.

One of the other advantages of these systems is the possibility of connecting to other safety equipment such as gas and water fire extinguishing systems. One of the other advantages of these systems is the possibility of connecting to other safety equipment such as gas and water fire extinguishing systems.
The technology of fire alarm systems is divided into two categories: addressable and conventional, where addressable technology is much newer, more reliable and better. Now, it might not be bad to get to know these systems a little.
Types of fire alarm systems
Conventional fire alarm systems
These types of systems are used for fire protection in small projects. Wiring in conventional fire alarm systems is linear or radial. Fire detection equipment is placed in separate circuits called Zone, and fire alarm equipment is installed in separate circuits. In this type of fire alarm system, only two wires are used for wiring each fire detection zone, and as it is clear from the diagram below, the wiring route in these systems starts from the control panel and passes through The equipment ends in the last part of the path. At the end of each path, an element at the end of the line (ohmic resistance, diode or capacitor) is used to return the current from one pole to another. This element at the end of the line is usually displayed in maps with EOL. The type of this element at the end of the line is determined by the manufacturer. All equipment in conventional systems must be of conventional type. In conventional fire detection and alarm systems, each area or zone includes a path of fire detection equipment, and typically for a multi-story building, each floor is a fire detection zone.

If we want to name the most used fire alarm system in the world, we will definitely reach the addressable fire alarm system. You just have to look at each part of the components of this system (detection, inputs and outputs in the loop, chassis) you can find a dedicated address that is connected to its control center!
This is the reason why this name is given to this type of fire alarm system The methods that these types of systems use for fire detection are completely similar to the normal fire alarm system, with the difference that all the equipment used in it has a dedicated address and it has the ability to detect all field components.
In general, in an addressable fire alarm system, you can see all the equipment, including sirens, inputs and outputs, switches, etc., in a loop. You can cover about 10,000 square meters with each ring, depending on the number of detectors. This is if you cannot determine the status of each detector relative to the proximity of the alarm.
Each of the addressable fire alarm system equipment has its own address, which is defined on the fire alarm control. In such a way that the control panel identifies the components through these addresses and announces the fire by exchanging information.
In such a system, zoning is done entirely by software and control panel, and several zones can be used in one ring. In the feeding loop, the exchange of information, equipment and signal communication between the equipment and the central addressable fire alarm control panel is done through a pair of systems.
Remember; The communication protocol in each of the addressable fire alarm system manufacturers is different from other manufacturers. So, in this system, you should only use the products of one brand in the loop.
Finally, fire alarm systems are also economical in terms of preventing potential damage costs to a significant extent. The fact that a fire occurs and then causes collateral and financial damage is one of the issues that can be easily prevented by installing and using fire alarm systems.
Considering the importance of protecting people and assets, installing and updating fire alarm systems as a preventive measure is inevitable. These systems add to the security and peace of mind of you and those around you and effectively protect your living and working environment from fire hazards.
The Safety Group of Navandish System Sabah Engineering Company is ready to bring you peace of mind by using the best available systems according to the needs and wishes of the employer.
