This advanced trim, engineered for Reliable's Model DDX deluge valves, provides robust protection against both fire hazards and the risk of accidental water discharge, making it an ideal choice for facilities where property and assets are highly susceptible to water damage.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSingle Interlock Operation\u003c\/b\u003e: This system is specifically designed to fill the sprinkler piping with water upon activation of an electrical detection system (such as smoke or heat detectors) *before* individual sprinkler heads open. Water is then discharged only when a sprinkler head reaches its thermal rating, ensuring a rapid response while mitigating accidental water release caused by pipe or sprinkler damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eIntegrated Supervisory Air System\u003c\/b\u003e: Pipes are supervised with air or nitrogen pressure. Should a pipe or sprinkler be damaged, a loss of this supervisory pressure triggers a trouble alarm, but crucially, it does not cause the preaction valve to open or water to flow into the system. This provides an early warning without immediate water discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimized for Reliable DDX Deluge Valves\u003c\/b\u003e: This trim segment is meticulously engineered for seamless integration with Reliable's renowned Model DDX deluge valves. These valves feature a hydraulically operated, differential-type design with an externally resettable clapper, simplifying post-activation reset procedures and reducing system downtime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDurable Construction\u003c\/b\u003e: Crafted from high-quality materials, the trim is built for longevity and reliable performance in demanding environments, upholding the trusted quality standards of the Reliable brand in fire protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePrecision Engineered (4DDXESPN)\u003c\/b\u003e: The specific \"4DDXESPN\" designation signifies a precisely configured and tested segment, ensuring optimal functionality and compatibility within your fire protection system.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eThis Reliable Preaction Trim Single Interlock Segment solves the critical challenge of providing effective fire suppression in areas where water damage is a significant concern. It is particularly beneficial for protecting valuable assets in locations such as data centers, server rooms, museums, archives, libraries, telecommunication centers, and cold storage facilities. By requiring a confirmed detection event before water enters the pipes, it prevents costly water releases from accidental impacts to sprinkler heads or piping. This offers facility managers and fire safety professionals enhanced peace of mind, knowing that both fire and inadvertent water damage risks are significantly minimized without compromising on rapid fire response capability.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Reliable Sprinkler","offers":[{"title":"Standard \/ Standard \/ N\/A","offer_id":48342765699320,"sku":"4DDXESPN","price":3457.82,"currency_code":"USD","in_stock":true}],"url":"https:\/\/fireprotectionparts.net\/fr\/products\/reliable-preaction-trim-single-interlock-segment-4ddxespn","provider":"Fire Protection Parts","version":"1.0","type":"link"}
