Sacremento Pre Action Fire Sprinkler System

Whenever you are concerned with an accidental fire sprinkler discharge such as rare, precious, computers or valuables that may be damaged when wet; the pre action fire sprinkler system may be the choice for fire prevention and fire protection. There are two main types of pre action fire sprinkler systems.

Single interlock pre action fire sprinkler systems generally are activated by a heat detector, smoke detector, or fire alarm. The pre action system activates and fills the fire sprinkler pipes with water and sprays the water from the fire sprinkler heads. The desired effect is to essentially convert a dry pipe fire sprinkler system into a wet pipe fire sprinkler system. If any air pressure is lost in the pre action fire sprinkler system a trouble alarm generally alerts you of the issues.

Double interlock pre action fire sprinkler systems generally are activated by a heat detector, smoke detector, or fire alarm. The double interlock pre action system activates and fills the fire sprinkler pipes with water and sprays the water from the fire sprinkler heads. The desired effect is to essentially convert a dry pipe fire sprinkler system into a wet pipe fire sprinkler system. If any air pressure is lost in the pre action fire sprinkler system a trouble alarm generally alerts you of the issues. The main difference is that all fire sprinkler heads remain open similar to a deluge fire sprinkler system.

NFPA 13D has created a standard for the installation of fire sprinkler systems, detailing information for the combined dry pipe and pre action system. “1.1* Scope. 1.1.1 This standard shall cover the design, installation, and maintenance of automatic sprinkler systems for protection against the fire hazards in one- and two-family dwellings and manufactured homes. 1.1.2 This standard assumes that the sprinkler system is designed to protect against a fire originating from a single ignition location.”
