The security alarm system is automatic system intended for reliable detection of the object intrusion event and notification (or reaction) system activation.
The fire alarm system is the automatic system intended for fast and reliable detection of the fire incipient based on recognition of the accompanying fire events, such as heat, smoke, infra-red radiation, etc. and notification and (or) firefighting systems activation.
Any Security and Fire Alarm System consists of following blocks:
- Concentrators or reception panels of control;
- The panel of central supervision;
- Notification and reaction devices.
Each security-fire alarm system uses security and fire detectors, supervising various physical parameters. Such types of security detectors, as infra-red passive, magnetic, detectors of breaking glass, perimeter active detectors, and combined active detectors are widely used. Thermal, smokes, light, ion, combined, manual and other detectors are applied in security and fire alarm systems.
According to the method of detection and alarm signal generation, detectors and security and fire alarm systems are divided into untargeted, targeted and analogue addressable.
The Automatic fire extinguishing systems allow to localize and to liquidate fire at early stage of the ignition. The structure of the fire alarm system includes specialized security panels, a temperature, smoke and other sensor controls, fire alarm buttons, devises of notification, etc. The fire alarm system works as a part of the uniform system and coordinated by the uniform operating center. Each extinguishing agents has own mechanism of fire quenching.
The water entering into the reaction zone and is turning into steam (non-flammable gas) which makes it difficult to flow the oxygen into the reaction zone. Besides, boiling water is absorbed the heat energy that reduces the general temperature in a reaction zone. The gaseous extinguishing is based on reducing the oxygen concentration due to entry nonflammable gases into the reaction zone. Moreover, liquefied gas during its release from the cylinder is accompanied by temperature decreasing; therefore, the temperature in the reaction zone also reduces.
However, the powders and aerosols have absolutely different fire fighting mechanism. The particles of a powder (aerosol) give a considerable quantity of chemically active centers and get in a reaction zone, and inactivate primary products of burning on a surface and thus to slow down the reaction.
An automatic firefighting system can be divided on:
- An automatic gas firefighting system;
- An automatic water firefighting system;
- An automatic powder firefighting system.
The system consists of:
- A step-pumping station (including pumps, panels and control valves components and supply pipe);
- A sprinkler or deluge network of sprinkler or deluge sprinklers (in the range of products includes hidden storage and irrigation canals);
- The transmitters and pressure and flow switches: solenoids, rotary valves, an air, a deluge, a solenoid, a sprinkler, the wet and dry valves, a pipeline with the mounting elements (clamps, gate valves, suspension for a pipe, parts for compound, stop valves, alarms).
The systems are applied to protect the trading and business centers, office buildings, sports complexes, hotels, the enterprises, warehouses, car-garages and parking places, banks, objects of power, military facilities and objects of a special purpose, apartment houses and cottages.
The necessity of the system installation and its type is defined by standard documents and parameters of the most protected object.
Today the owners of buildings, design or building organizations are faces with the problem of the equipment choice for their expensive objects protection. The RCI-Consulting will help you to make a correct choice. We offer the firefighting solutions to the Customers with consideration of such criteria as a quality, reliability, cost of installations and maintenance.
