Mich. Admin. Code R. 400.10529 - Sprinkler systems
Rule 529.
(1) A
sprinkler system in a new or converted facility shall comply with the
provisions of the national fire protection association pamphlet no. 13, 1980,
entitled "Installation of Sprinkler Systems." Where there is no adequate water
from a community water system to supply a sprinkler system and where the area
to be protected is not more than 20,000 square feet, a special pressure tank
supply for sprinklers, as specified in the national fire protection association
pamphlet no. 22, 1981, entitled "Standard for Water Tanks for Private Fire
Protection," shall be provided. The special pressure tanks shall contain 2,000
gallons of water in a 3,000-gallon tank for partial systems and for complete
building systems shall have 3,000 gallons of water in a 4,500-gallon tank.
The tank shall be enclosed in at least a 1-hour-fire-resistance rated structure or room.
(2) All required sprinkler systems shall be
inspected and tested and all other maintenance performed as specified in the
national fire protection association pamphlet no. 13A, 1981, entitled "Care and
Maintenance of Sprinkler Systems," at least once a year by a sprinkler
contractor. The licensee shall maintain documentation of the last inspection
and test.
(3) A sprinkler system in
an existing facility that is approved before these rules take effect shall
continue to be approved until the facility or a portion thereof is remodeled,
converted, or expanded. The system shall be maintained in accordance with the
standards applicable at the time it was originally approved.
(4) When an existing facility is remodeled,
converted, or expanded and the remodeling, conversion, or expansion results in
an existing sprinkler system that does not provide adequate protection, fire
protection shall be provided by extension of the current system where it is
possible to extend the system and maintain its integrity or a new sprinkler
system shall be installed in the affected area.
(5) The sprinkler piping for any isolated
hazardous area that can be adequately protected by not more than 2 sprinklers
may be connected directly to the domestic water system at a point where a
minimum 1-inch supply is available. An approved OS and Y valve and check valve
shall be installed between the sprinklers and the connection to the domestic
water supply.
