Construction and maintenance of fire alarm systems

Main and main goal of any fire alarm system is prevention and preventing the spread of fire. In the presence of one of the elements of the fire - smoke, flame, heat, the system generates an alarm signal, and thus the spread of fire can be located and prevented. Depending on the fire risk and specific application systems, fire alarm can be two main types:

  • Conventional alarm systems are suitable for small spaces and sites where fires can be detected quickly. The detectors are connected to a cable line that extends from the control panel and ends with the final element. To pass the detector in alarm mode, the system does not know who all detectors is activated and therefore can not locate the site. The cost of conventional systems is lower compared to that of addressable, so customers often prefer them. Their main disadvantage is that not locate the place of fire and sometimes produce false signals.
  • The addressable fire alarm systems are suitable for large objects and those with complex and specific architecture. With this type of fire detector systems and other peripherals are arranged in a circle on the cable line that starts from the control panel and ends in it. This allows for full recognition of the devices on an individual address. The main advantages of addressable systems are locating the exact location of the fire, responsiveness, lack of false alarms.

Fire alarm designed and implemented by GI Enterprise Ltd., are of extremely high quality and reliability. They meet the standards BS EN 54 and SD CEN / TS 54-14 and comply with all applicable country regulations.
