What are fire alarm systems? What are they used for?

Fire Alarm Systems is the generic name for the entire system which detects the fire at the starting phase and provides intervention opportunity to the relevant units with warning elements by generating warning messages with different detection elements and which saves time for evacuation of premises by deactivating units those might cause danger. Fire alarm systems, which it is possible to deliver solutions for every application by various detection elements, are used in houses, offices, factories, malls, schools, hospitals and similar places.

Fire alarm systems has a fire detection panel. This panel is formed of different detection elements and they are detectors, buttons, siren – flasher and similar.

Fire alarm system activates these elements. Fire detection and alarm systems are two types; conventional and analog addressable.

 

 

 

Conventional and Addressable Systems

Detection panel applied in the conventional fire detection systems are formed of zones in which detection elements are included. The most important factor that determines the number of the zones is the capacity of the Panel. More than on detector can be connected to each zone and there are inputs and outputs where fire alarm buttons and sirens can be connected.

When a detector detects a fire or the fire alarm button is pressed the said detector triggers a warning signal from the zone on the panel where it belongs to.

It is impossible in such systems to know which detector generates signal.

However in addressable fire detection systems there are loop lines connected to the detectors according to the conventional systems. Number of the loop lines and cabling distance is in proportion with the capacity of the panel applied. Detectors or buttons can be connected to a loop line according to its capacity.

Detectors or buttons within the loop can be separated to zones within themselves. Besides, the panel can be individually detected by the help of switches on each detection element. This situation means that it can be determined which detector or button is sending the signal.
