A fire detection, signaling and warning system is a protective installation designed to detect and signal the occurrence of a fire start in protected areas as soon as possible as well as to alert staff, And any other category of people in the area who can help to extinguish the fire and limit its effects.
Fire detection, signaling and warning systems may have the following components:
– Fire detection elements (smoke, temperature, carbon monoxide, flame sensor, smoke detection barriers, aspirating smoke detection etc.)
– Control and signaling equipment (control panel )
– Fire alarm devices (optical elements, indoor or outdoor sirens)
– One or more manual call point
– A fire alarm device or technical fault signals
– Command system for automatic fire protection systems
– Power supply with batteries
Fire detection, signaling and fire detection systems are divided according to the type of technology used in conventional systems and addressable systems. Addressable systems are intended for large-area buildings, many rooms requiring rapid identification of the signal . The Normative 118/3 of 2015 specifies the characteristics of spaces requiring addressable detection systems; So addressable systems are mandatory for buildings that have detection areas with an area of more than 1000 square meters. Also, in buildings with a surface area greater than 10000 square meters or more than 1000 detection elements, a hazard management system must be provided to facilitate the identification of the area where the alarm occurred.
The advantages of the addressable fire detection system are: rapid identification of the signal source via the alphanumeric display, the rapid upgrade possibility for rebuilding or extension of the building, easier integration in a unitary building management system.
The advantages of the conventional system are: the low price for both equipment and labor (due to the low level of expertise for system programming).
