WHAT’S IN A SPRINKLERED COMMERCIAL SPACE?












Quite often – your commercial space is going to be equipped with sprinklers (hence the term “sprinklered”.

There are 5 types of sprinkler systems:

1. A Dry Pipe Sprinkler System is a fire-protection system that utilizes water as an extinguishing agent. The system piping from the Dry Pipe Valve to the fusible sprinklers is packed with pressurized air or nitrogen. An air check system is a small dry system that's directly connected to a wet pipe system. The aircheck system uses a dry valve and an air supply but doesn't have a separate alarm. The alarm is provided by the main alarm valve.

2. A Wet Pipe System is fixed fire protection using piping packed with pressurized water supplied from a dependable source. Closed heat sensitive automatic sprinklers spaced and located in conformity with recognized installation standards are utilized to detect a fire. Upon operation, the sprinklers distribute the water over an exact area to regulate or put out the fire. As the water flows through the system, an alarm is activated to show the system is working. Only those sprinklers immediately over or adjacent to the fire operate, minimizing water damage.

3. A Deluge System is a fixed fire-protection system that floods a zone with pressurized water through a system of piping and open nozzles or sprinklers. The system piping is empty until the deluge valve is activated by a hydraulic, pneumatic, electric, or manual release system.

4. The Firecycle Sprinkler System is of the open sprinkler head deluge design. The deluge system is designed to limit the damage, which can be caused by excessive water flow. The deluge system is fully automatic and designed for on/off operation. The detection method is a fixed temperature, self-restoring heat detectors. The on/off operation cycles when the heat detector senses heat regeneration when detector cools and restores, system operation will stop. Water flow is controlled through a 90° pattern or straight-through pattern, spring aided flow control valve. Once the system has operated, a strobe and alarm will be activated at the instrument panel. The strobe and alarm won't deactivate until the system is manually reset to normal operation.

5. ESFR Sprinklers are designed to release 2-3 times the quantity of water of conventional sprinkler heads and to release larger droplets of water, which have greater force than droplets discharged from conventional heads. As a result, more water and a greater portion of the water reach the fire allowing the flames to be put out.
