Fire Alarm Systems

Fire detection and alarm systems, which are one of the indispensable elements of fire extinguishing systems, ensure that the fire is detected in a minimum time interval and the system is activated.

After the smoke detector detects, it transmits to the main panel and the system notifies the fire in the detected area. In this way, it is important for the evacuation of the environment, as well as giving the chance to intervene in newly started fires.

Fire alarm systems are systems that are active in any fire risk or situation. The basic components that make up this system are; detector, control panel, system and power supply.

Fire warning systems, which can make very sensitive measurements, are not noticed by people under normal conditions; It predetermines possible fire risks such as gas leakage, smoke, spark, abnormal temperature increase and gives warning. In this way, it becomes possible to intervene in a possible fire situation in advance and as soon as possible.

When we examine the regulation on "Fire Protection of Buildings", which was renewed in 2007 and published in the official gazette, we see that these systems are a necessity in commercial enterprises.

There are basically two different fire alarm systems that can be applied according to the structural features of the buildings. These; conventional and addressable fire alarm systems.

Conventional Fire Alarm Systems
Conventional fire alarm systems are systems where more than one detector works at the same time. Therefore, no matter where there is a fire risk or situation in a building where this system is installed, a fire alarm is activated in every part of the building. Because in the conventional fire alarm system, the detectors are connected in parallel to each other. So they are not independent of each other.

In conclusion, we can say that the conventional system is a good option, especially for small spaces or buildings such as houses. As a matter of fact, this system will be both inconvenient and insufficient for multi-storey and large buildings such as hospitals, libraries and hotels. For this reason, addressable fire detection systems are a more accurate choice.

Addressable Fire Alarm Systems
Addressable fire alarm systems are a system in which each detector performs its function independently of each other. The fact that the detectors work independently of each other provides a great advantage in a large or multi-storey building. In this way, the point of fire danger can be easily determined and a more effective intervention can be carried out in a shorter time.

Detectors used in addressable fire alarm systems have advanced features. It reflects information such as whether the fire is real or not, its degree and smoke values ​​to the system.
Fire Alarm Systems Features

Common features of both conventional and addressable fire alarm systems;

  • Detectors and sensors are used.
  • Sensitivity rate can be adjusted.
  • It sends an immediate signal in case of fire (condensation of heat or smoke).
  • Activates water jets at the risk of fire or instantly.
  • It measures the degree of heat or smoke and sends it to the system.
  • Warns authorized persons.

As a result; The characteristics of the building where the fire alarm systems will be installed, such as being single or multi-storey, having a wider or narrower area, should be taken into account. In this way, the system can be set up for the most efficient use.
