A key aspect of fire-alarm systems is to alert in a short timeframe for presence of fire, that is, to timely evacuate people and begin extinguishing the fire before it reaches serious proportions. In addition to sound and light warning signals in the event of an alarm, intelligent fire alarm systems also offer the option of forwarding alarm signals to fire brigades, activating executive functions such as switching off electric power supply, switching off ventilation, switching on smoke extraction, opening doors and more. With the societal progress and the care for human life, certain buildings are required by rules, regulations and laws to install fire-alarm systems. The concept of fire-alarm system needs to be defined by a project that is precisely determined using the correct elements with regards to the type, size and purpose of the building/room. Fire-alarm systems can be divided to: conventional, addressable and analog-addressable. Intelligent systems are analog addressable that provide additional security, have the ability to accurately determine the events microlocation in the building as well as additional functions of the elements. Proper installation and detailed configuration of the system minimizes the possibility of delayed fire detection and false alarms, which contributes to the quality of the system as well as customer satisfaction.
