Fire safety systems

Fire-fighting systems are a complex set of technical means that ensure the timely detection of a source of smoke or fire on the site. Also their purpose is to promptly inform the people on the site with the directions of evacuation and take emergency measures for fire fighting, which is why their other common name is security fire protection systems.

Composition and principle of operation of fire fighting systems

Effective implementation of firefighting systems of their tasks is ensured by the well-coordinated work of the information systems entering into this complex:

  • Security and fire alarm systems;
  • Systems of loud-speaking notification and evacuation control;
  • Automatic fire extinguishing and smoke-evacuation (ventilation) systems;
  • Access control system (ACS);
  • Video surveillance systems;
  • Cable system (SCS);
  • Power supply systems;
  • Centralized monitoring and management system.

The fire safety systems start with fire alarm sensors that react to such changes in the environment as smoke level, temperature, gas contamination, traffic intensity, etc. The sensors periodically “take off” information from the outside and transmit it to the control panel or analyze information Independently and in the event of a mismatch, an alarm is sent to the control center and / or to the corresponding devices of other information systems.
One such system is an alarm system. Its equipment is designed to provide an audio or voice alarm message and announce the evacuation order from the risk areas. Moreover, at large facilities the system divides the premises into several priority zones: as a rule, the employees of the facility are notified first about the fire, and only then the visitors. If necessary, the sound signals are supplemented by a light indication and are almost always accompanied by an emergency illumination of the buttons and the “Exit” display.
Fire-fighting systems would not be effective enough without integration with an automatic fire-extinguishing system that eliminates or stops the spread of fire before the arrival of fire services. In turn, the smoke removal system neutralizes the concentration in the surrounding atmosphere of toxic substances.
The cable system can be called the blood vessels of fire fighting systems. That is why it is so important that the installation of the SCS cable network is carried out accurately and in full compliance with modern technical requirements, ensuring optimal channel capacity, their high reliability, flexibility and security. Also, a prerequisite for the uninterrupted operation of fire fighting systems is the availability of backup power, which in the event of interruptions with a centralized power supply will help the system to survive on its own energy resources for at least two and a half hours.
