Sprinkler Systems

Circum offers expert knowledge and can provide recommendations including design and installation for a range of sprinkler system solutions. Historically used in large commercial buildings and warehouses, developments mean it may be a cost effective solution in smaller buildings and residential homes. Sprinkler systems remain an effective method of fire protection and in protected buildings over 99% of fires were controlled by fire sprinklers alone.

Fire sprinkler options include:

Wet System – permanently charged with water, wet systems are ideal where temperatures will not fall below freezing point. Wet pipe sprinkler systems are installed more often than all other types of fire sprinkler systems. They also are the most reliable, because they are simple, with the only operating components being the automatic sprinklers and the automatic alarm check valve.

Dry System – permanently charged with air and used to protect unheated premises such as warehouses, parking garages, attic spaces and other areas exposed to freezing temperatures.

Pre-Action System – Ideal for use in locations where accidental activation is undesired, such as in museums with rare art works, manuscripts, or books; and Data Centers, for protection of computer equipment from accidental water discharge. Pre-action systems are hybrids of wet, dry, and deluge systems, depending on the exact system goal..

Deluge systems – Ideal for properties with special hazards where rapid fire spread is a concern, as they provide a simultaneous application of water over the entire hazard. Designed to protect high hazard areas containing a severe fuel hazard with a high heat release rate by bringing a large number of open sprayers into action simultaneously in the event of a fire

Foam water sprinkler systems – a special application system, discharging a mixture of water and low expansion foam concentrate, resulting in a foam spray from the sprinkler. These systems are usually used with special hazards occupancies associated with high challenge fires, such as flammable liquids, and airport hangars.
