FIRE DETECTION SYSTEMS
Addressable Detection and Notification System
Addressable fire detection systems have microprocessor infrastructure. Today, they are the most advanced systems used in fire alarm systems. Each detection element has an address and there is a continuous communication between the Alarm Panel and all elements (detector, button, module, etc.). In this way, the status of each sensing element is continuously reported to the panel. Another advantage of active communication between the sensing elements and the panel is in the cabling. In these systems, economy can be achieved in cable cost and labor.
The systems have very advanced software. In this way, many different variations can be made easily in terms of operation. In addition, the systems can be controlled via an online computer. Addressable systems are supplemented with various additional field materials to collect information from other auxiliary systems or to activate or deactivate related systems, as well as sensing elements.
For instance; The Monitoring Module is used to monitor the positions of fire extinguishing systems pumps, flow switches and line shut-off valves, fire dampers, or the control module is used to control elevators, activate smoke exhaust fans, close fire doors, and make local notifications. These different addressing methods are very important during the installation and use of the system.
Conventional Detection and Warning System
Conventional fire alarm panels are the simplest of fire detection systems. It comes from the collective group formed by the sensing elements, called the warning zone. There is no chance to understand from which element (detector, button, etc.) the notification came. For this reason, the use of conventional systems in environments such as hotels and offices necessitates research in the area where the fire is reported, which causes a waste of time.
The system consists of sensing elements connected in parallel one after the other in each zone. The system performs line control on a zone basis, thanks to a resistor called End of Line Resistance (E.O.L) connected to the very end of the line, thanks to a current circulating in the circuit continuously. If, for any reason, the line is cut and any of the detectors come out, a fault notification is given in the relevant zone, since this current cannot circulate in the circuit. Thus, the line is protected against open circuit.
In the alarm state, although there are some differences between the systems, the basic structure is the same. There is one current limiting circuit per zone. Detection elements short-circuit the zone line in case of alarm. The current flowing through the line is kept at a certain limit by the current limiting circuit. At the same time, fire alarm takes place.
Special Gas Extinguishing panels are also included in this group. As a basic structure, there are two detection zones in an extinguishing zone. When a fire alarm is received from both zones, the extinguishing output is activated with a simple circuit. The solenoid valve becomes active and extinguishing takes place.
