Fire sprinkler installations are automated detection systems, signaling and fire extinguishing using water as the extinguishing agent. Provides a safe and effective fire protection when well chosen, sized and installed correctly, and operated and maintained systematically by providing:
- danger or risk of fire;
- location, building flammability and value.
Sprinkler systems are used to:
- closed construction and special categories of exceptional importance;
- soundstages arranged and closed television studios;
- theaters, Department stores, warehouses, freight;
- underground parking garages and more than 50 cars and closed at the ground more than three levels.
Sprinkler installation must always be under pressure and can be done in the following systems: type of water – water and water – air type.
Water systems – water is used to protect buildings where there is danger of frost.
The principle of operation is as follows: valve triggers fire alarm check valve functions as a normal and generates an alarm when a sprinkler activates minimum and senses flow rate. ACS connecting pipes are filled with water sprinklers switch- fire immediately. Chamber of delay is added to prevent accidental triggering the fire alarm if mains water pressure to ACS acquis is not constant.
Water-air systems are used to protect buildings where there is no heating.
Operation is similar to water-water system, the difference being that the pipes in the distribution network connected to the control and signaling devices are not filled with water, but with compressed air or nitrogen. Thus, in case of fire sprinkler acquis which opens generates a pressure drop in the system required to operate the valve opening and trigger the alarm. All system components guarantee a prompt and effective action of fire, the very first moments. Accelerator ensures rapid evacuation of air from the pipes allowing water to fill the sprinkler piping and sprinklers act in a very short time.
