Revised, Addendum No. 1, 1117100
PART 1 - GENERAL
1.1 RELATED DOCUMENTS
A. Drawings and general provisions of the Contract, including General and Supplementary Conditions
and Division 1 Specification Sections, apply to this Section.
B. "1997 Edition of the Minnesota Uniform Fire Code as Amended.
C. Factory Mutual Data Sheet 8-9 for storage room fire protection.
D. Factory Mutual Research Data Sheet 2-8N ior sprinkler system installation guideline.
1.2 SUIviMARY
A. This Section specifies standpipe and sprinkler systems for buildings and structures.
B. Related Sections: The following Sections contain requirements that relate to this Section:
i. Divisiori 7 Sections fcr materials and methods for sealing pipe penetrations through exterior and
foundation walls, and fire and smoke barriers.
2. Division 15 Section "Basic Mechanical Requirements."
3. Division 15 Section "Basic Mechanical Materials and Methods".
4. Division 16 Secfions for power supply wiring including disconnacts, motor starters, and required
electrical devices.
5. Division 16 Sections for fire alarm system connections to water flow indicators, pressure
switches, and alarm devices for fire protection systems.
1.3 DEFINITION
A. Pip2 sizes used in this Section are nominal pipe size (NPS) specified in inches.
B. Working plans as used in this Section refer to documents (including drawings and calculations)
prepared pursuant to requirements in NFPA 13 for obtaining approval of authority having
jurisdiCtion.
C. Other definitions for fire protection systems are included in referenced NFPA standards.
1.4 SYSTEM DESCRIPTION
A. bVet-Pipe Sprinkler System: System with automatic sprinklers attached to piping system containing
water and connected to water supply so that water discharges immediately from sprinklers when
they are opened by the heat of a fire.
B. Dry-Pipe Sprinkler System: System with automatic sprinklers attached to piping system containing
air under pressure. Release of pressure (opening of sprinklers) permits water pressure to open
dry-pipe valve. Water then flows into piping and discharges through open sprinklers.
1. Pressurizing Gas: Compressed air, from sprinkler system air compressors.
C. Preaction Sprinkler System: System with automatic sprinklers attached to piping system containing
air that may be under pressure. include inter-connection to supplemental fire detection system in
same areas as sprinklers. Actuation of fire detection system opens deluge valve permitting water
flow into sprinkler piping system and discharge from sprinklers that have opened.

MECHANICAL CONSTRUCTION
D. Combination Dry-Pipe and Preaction Sprinkler System: System with automatic sprinklers attached
to piping system containing air under pressure. Include connection to supplemental fire detection
system in same areas as sprinklers. Operation of fire detection system actuates tripping devices
that open dry-pipe valves simultaneously and without loss of air pressure in system. Operation of
fire detection system also opens approved air exhaust valves at end of feed mains. This helps fill
system with water and usually precedes opening of sprinklers. Fire detection system will also
activate fire alarm system. Water discharges from sprinklers when they are opened by fire.
1. Pressurizing Gas: Compressed air, from sprinklersystem air compressors.
E. Deluge Sprinkler System: System with open sprinklers attached to piping system connected to
water supply through deluge valve. Valve is opened by operation of fire detection system in same
areas as sprinklers. When valve opens, water flows into piping system and discharges from
attached sprinklers.
F. Sprinkler System Protection Limits: All spaces with the building. Provide 100 percent coverage.
G. Standpipe Systems: Systems that are wet type have water supply valve open and pressure
maintained at all times and include branches extending from standpipes to sprinkler zone valves.
H. Combined Class I, Standpipe and Sprinkler System: Arrangement of piping, valves, fire department
valves, hose connections, and accessories for use by persons trained in use of heavy fire streams.
Fire department valves are 2-1/2-inch size. Sprinkler piping extends from standpipes.
