The type of sprinkler to be installed will be determined by the Building Official. It may be an <br /> NFPA 13, NFPA 13R, or NFPA 13D system depending upon several factors. Sprinkler <br /> installation shall not begin without an approved and stamped set of plans from the <br /> Engineering & Public Services Department. The Fire Department will also review the <br /> plans and shall field inspect the installation based only on approved plans that must be on <br /> site. Changes to plans must be approved by both the Engineering & Public Services and <br /> Fire Departments. <br /> Aboveground sprinkler piping shall be hydrostatically tested as established in NFPA <br /> Standard 13. Underground piping shall be hydrostatically tested and flushed as established <br /> in NFPA Standard 24 for private fire mains. (Below-ground piping must be installed by <br /> Washington State Patrol Licensed Underground Sprinkler line certified "U" installers. <br /> For further information, contact the State Fire Marshal's Office at(360) 570-3134 or <br /> contact the Everett Fire Department at(425) 257-8124.) All such tests shall be witnessed <br /> by a Fire Department Inspector. Call (425) 257-8126 to make an appointment for inspection. <br /> Contractors' materials and test certificates shall be submitted to the Everett Fire Department <br /> prior to issuance of any Certificates of Occupancy. <br /> Call (425) 257-8124 for more information. <br /> Each building is required to meet NFPA 13. Each structure is to have its own sprinkler room. <br /> 15.The Snohomish County Emergency Radio System is employed by the City of Everett Fire <br /> Department emergency crews and operates at 800 MHz. Large metal-framed or metal and <br /> concrete buildingscan weaken the signal so that communication and, therefore, firefighter <br /> safety is compromised. This structure must meet the requirements of EMC 16.03.060, <br /> Section 511, which specifically addresses required radio system performance standards in <br /> this structure. Your attention to this feature early in the planning stages will help avoid <br /> a costly, last-minute retroactive installation of radio signal amplification antennae and <br /> other equipment.
