Depending on scale of problems which are solved by the fire alarm system, its structure includes the equipment of three basic categories:
The equipment of the centralised management of the fire alarm system (for example, the central computer with established on it Software for management of the fire alarm system; in small systems of the fire alarm system of a problem of the centralised management the fire alarm panel) carries out;
The equipment of gathering and processing of the information from gauges of the fire alarm system: devices control fire alarm (panels);
Touch devices – gauges and detectors the fire alarm system.
Integration of the security and fire alarm system as a part of uniform system of the fire alarm system is carried out at level of the centralised monitoring and management. Thus systems of the security and fire alarm system are administered by the posts of management keeping autonomy as a part of system of the security-fire alarm system independent from each other. On small objects the fire alarm system copes control devices
The control device carries out a food security and fire detectors on loops of the fire alarm system, reception of disturbing notices from detectors, forms disturbing messages, and also transfers them to station of the centralised supervision and forms alarm signals on operation of other systems.
The system of the security alarm system as a part of the fire alarm system carries out of a problem of the timely notification of a protection service on the fact of unapproved penetration or attempt of penetration of people in a building or its separate premises with fixing of date, a place and time of infringement of a boundary of protection.
The system of the fire alarm system is intended for timely detection of a place of ignition and formation of operating signals for notification systems about a fire and automatic fire suppressions.
The basic functions of the fire alarm system are provided with various means. For fire detection serve detectors, for processing and recording of the information and formation of operating alarm signals — control equipment and remote terminal units.
Except these functions, the fire alarm system should form teams on inclusion of automatic installations fire suppressions and smoke removals, notification systems about a fire, technological, electrotechnical and other engineering equipment of objects.
