The pre-action sprinkler system is hybrids of wet, dry, and deluge systems depending on the exact system goal. There are two main subtypes of pre-action sprinkler systems: single interlock fire sprinkler system, and double interlock fire sprinkler system.
The operation of single interlock sprinkler systems are similar to dry fire sprinkler systems except that these systems require that a "preceding" fire detection event, typically the activation of a heat or smoke detector, takes place prior to the "action" of water introduced into the system's piping by opening the pre-action valve, which is a mechanically latched valve (i.e. similar to a deluge valve). In this way, the system is essentially converted from a dry system into a wet system. The intent is to reduce the undesirable time delay of water delivery to sprinklers that is inherent in dry systems. Prior to fire detection, if the sprinkler operates, or the piping system develops a leak, loss of air pressure in the piping will activate a trouble alarm. In this case, the pre-action valve will not open due to loss of supervisory pressure, and water will not enter the piping.
The operation of double interlock systems is similar to deluge systems except that automatic sprinklers are used. These systems require that both a "preceding" fire detection event, typically the activation of a heat or smoke detector, and an automatic sprinkler operation take place prior to the "action" of water introduced into the system's piping. Activation of either the fire detectors alone, or sprinklers alone, without the concurrent operation of the other, will not allow water to enter the piping. Because water does not enter the piping until a sprinkler operates, double interlock systems are considered as dry systems in terms of water delivery times, and similarly require a larger design area. Fire Sprinkler System Texas has been installing these systems in Houston, TX. Fire Sprinkler System Texas is one of the most experienced Fire Sprinkler companies in Houston.
The framework's release is a two-advance process: First, the imaginative identification framework distinguishes smoke or warmth, which enacts a pre-activity valve that enables water to stream into funneling and viably makes a wet pipe sprinkler framework. Second, a singular sprinkler makes a beeline to let water stream onto the fire. This second step gives an additional dimension of security against accidental release, which makes pre-activity frameworks perfect for water-touchy conditions.
Fire Sprinkler System Texas plans, introduces and fixes pre-activity pipe fire sprinkler frameworks for an assortment of organizations that work high-peril modern and business applications, including documented vaults, compelling artwork storage spaces, uncommon book libraries, and PC focuses.
Pre-action sprinkler systems are specialized for use in locations where accidental activation is undesired, such as in museums with rare artworks, manuscripts, or books; and data centers, for protection of computer equipment from accidental water discharge.
