Code of Maine Rules › 16 - DEPARTMENT OF PUBLIC SAFETY › 219 - OFFICE OF STATE FIRE MARSHAL › Chapter 4 - WATER-BASED FIRE PROTECTION SYSTEMS › DESIGN AND INSTALLATION OF LIFE-SAFETY SPRINKLER SYSTEMS › Section 219-4-2 - INSTALLATION

Current through 2024-29, July 17, 2024
2-1 Devices and Materials
2-1.1 Only listed new residential sprinklers shall be
					 employed in the installation of life-safety sprinkler systems. Standard
					 sprinklers or fast-response sprinklers of intermediate or high temperature
					 rating may be installed in areas of high ambient temperature. Sprinklers shall
					 be listed.
2-1.2 Only listed and approved materials and devices shall
					 be used in sprinkler systems.
Exception: Listing may be waived for tanks, hangers, water
					 flow detection devices and water control valves. All electrical components must
					 be U.L. listed.
2-1.3 Pre-engineered systems shall be installed within the
					 limitations which have been established by the testing laboratories where
					 listed.
2-2 Acceptance Tests
2-2.1 The installer shall perform all required acceptance
					 tests,, complete the Contractor's Material and Test Certificate(s), and forward
					 the certificates to the "authority having jurisdiction", prior to asking for
					 approval of the installation.
2-2.l.l When the "authority having jurisdiction" desires to
					 be present during the conducting of acceptance tests, the installer shall give
					 advance notification of the- time and date the testing will be
					 performed.
2-2.2 Underground mains and lead-in connections to system
					 risers shall be flushed before connection is made to sprinkler piping, in order
					 to remove foreign materials that may have entered the underground piping during
					 the course of the installation. For all systems, the flushing operation shall
					 be continued until water is clear.
2-2.2.1 Underground mains and lead-in connections shall be
					 flushed at the hydraulically calculated water demand rate of the system,
2-2.2.2 To avoid property damage, provision shall be made
					 for the disposal of water issuing from test outlets.
2-2.3 All aboveground piping shall be hydrostatically
					 tested at 200 p.s.i. for two hours, in accordance with N.F.P.A. #13, Standard
					 for the Installation of Sprinkler Systems.
2-2.4 It is suggested, but not required, that all
					 underground supply piping from the water utility shut-off to the sprinkler
					 system connection be hydrostatically tested at 50 p.s.i. above the expected
					 static pressure for two hours, to ensure the reliability of the materials and
					 installation.

TEST DESCRIPTION
HYDROSTATIC: Hydrostatic tests shall be
								mad at not less than 200 psi (18.6 bars) for two hours or 50 psi (3.4 bars)
								above static pressure in excess of 150 psi (1.07 bars) for two hours.
								Differential dry-pipe valve clappers shall be left open during test prevent
								damage. All aboveground piping leakage shall be stopped.
FLUSHING:
								Flow the required rate until water clear as indicated by no collection of
								foreign material burlap bags at outlets such as hydrants and blow-offs. Flush
								at flows not less than 400 GPM (1514 L/min) for 4-inch pipe, 600 GPM ( 2271
								L/min) for 5-inch pipe, 750 GPM (2833 L/min) for 6-inch pipe, 1000 GPM (3785
								L/min) for 8-inch pipe, 1500 GPM (5678 L/min) for 10-inch pipe and 200 GPM
								(7570 L/min) for 12-inch pipe. When supply cannot produce stipulated flow rate
								obtain maximum available.
PNEUMATIC: Establish 40 psi (2.7 bars)
								air pressure and measure drop which shall not exceed 1 % psi (0.1 bars) in 24
								hours. Test pressure tanks at normal water level and air pressure and measure
								air pressure drop which shall not exceed 1% psi (0.1 bars) in 24 hours.
