Fire Sprinkler Systems
Fire Sprinkler Systems
Automatic fire sprinkler systems (also known as a wet pipe systems are widely regarded as the most effective method of controlling fires caused by a broad range of hazards. With a century of proven experience, Gielle offers end-to-end sprinkler systems to protect your people, business and assets.
Sprinkler systems can automatically detect a fire, transmit an alarm and control the fire. This can be the difference between a minor accident and a major business shutdown. Led by professional project managers, Gielle’s engineers design, install and commission reliable, cost-effective sprinkler systems by carefully analysing your buildings and facilities in terms of occupancy, operation and fire risk. Our financial stability, backed with our corporate resources gives us the advantage to be able to deliver the best possible fire safety solutions required.
From specialised industrial warehouses and storage facilities through to residential buildings, high rise commercial towers, shopping centres, hospitals, hotels, libraries and more, Gielle has got you covered.
Preaction Sprinkler Systems
Traditional “wet pipe” sprinkler systems offers protection against fires, but can result in water damage if unnecessarily activated in sensitive areas, such as; computer rooms, museums, libraries or refrigerated areas. That is why there are single or double interlock preaction systems that can be configured to allow time for alternative fire extinguishment before the sprinklers are activated.
Traditional “wet pipe” sprinkler systems offers protection against fires, but can result in water damage if unnecessarily activated in sensitive areas, such as; computer rooms, museums, libraries or refrigerated areas. Single or double interlock preaction systems can be configured to allow time for alternative fire extinguishment before the Water Deluge Systems are activated.
According to your specific requirements, fire hazard and fuel load, Gielle can design a system that is activated by wet or dry pilot sprinklers or electric detectors and can be automatic or manually operated. Having designed and installed hundreds of systems for applications large and small, Gielle can work with you to deliver a solution to meet your needs and budget.
Single Interlock Preaction Systems
Single interlock preaction systems protect areas where there is danger of serious water damage that might result from damaged automatic sprinklers or piping. Typically, such areas include computer rooms, storage areas for valuable artifacts, libraries and archives. Preaction systems are effectively used to protect properties where a prealarm of a possible fire condition may allow time for fire extinguishment by alternate suppression means, prior to a sprinkler discharge. In the event the fire cannot otherwise be extinguished, the preaction sprinkler system will then perform as the primary fire protection system.
Double Interlock Preaction Systems
Double interlock preaction systems are designed for applications such as refrigerated areas that require the maximum degree of protection against an inadvertent operation that could result in unnecessary flooding of the sprinkler system piping.
In order to actuate the double interlock preaction system, two independent events, caused by a fire condition, must occur. The sprinkler system piping must lose air or nitrogen pressure due to the operation of one or more sprinklers, and the deluge releasing panel must energize and open the solenoid valve upon the operation of a fire detection device. The double interlock system will operate only when both the dry pilot actuator and the solenoid valve are open at the same time. Opening of the dry pilot actuator only (for example: a forklift truck accidentally dislodges a sprinkler) or of the solenoid valve only (for example: accidental operation of an electric manual pull station) will cause an alarm, and will not trip the system or flood the sprinkler system piping.
