is a component of the system that gives signals/signs after a fire symptom is detected. A fire sensing system or commonly known as a fire alarm system is a an integrated system that is designed and built to detect signs of fire, to then give a warning (warning) in the evacuation system and followed up automatically or manually with a fire fighting system. The main equipment that controls this system is called Main Control Fire alarm (MCFA) or Fire Alarm Control Panel (FACP) which functions to receive input signals (input signal) for all detectors and components other detector, to then provide an output signal (output signal) through the output component in accordance with the settings that have been applied.
Types of Fire Alarm Systems.
1. Non Addressable System.
This system is also called the conventional system. on this system MCFA accepts direct input signal from all detectors (usually very limited in number) without addressing and directly ordered component output to respond to the input. This system generally used in small-sized buildings/supervision areas, such as housing, shops, small schools, restaurants, apartments or in certain rooms in a secured building. The following is a basic diagram of a fire alarm system conventional.
2. Semi Addressable System.
In this system grouping/zoning is carried out on detectors & devices input recipients based on supervisory area. Each of these zones is controlled (both input and output) by the zone controller which has a specific address. At the time of the detector or tool other input receiver gives a signal, then the MCFA will respond (I/O) based on the zone controller that feeds it. On the MCFA display will read the address of the zone where fire symptoms occur, so with thus the action to be taken can be localized only in that zone.
3. Full Addressable System
Is the development of a semi addressable system. Fully addressable panels are more advanced than conventional systems, with more information capacity great control and flexibility. Addressable fire alarm panels are introduced by many microcontroller manufacturers in the mid-1980s. on this system all detectors and input devices have a specific address,
so that the process of extinguishing and evacuation can be done directly at the point who had a fire. The most basic difference with the conventional system is in terms Address. In this system each detector has its own address to state his/her identity. So the point of fire is known with certainty, because the panel can inform the detection comes from the detector Which one. In order to be able to inform the address/ID, a letter is needed here module called the Monitor Module. The conditions are one module for one detector, so that a truly addressable system is obtained
(fully addressable). If conventional detectors are to be addressable, then he must be connected first to the monitor module
