Fire Protection Construction Documents Fire Sprinkler Narrative Report for Smith College Residence Conversion 146 Elm Street Northampton, Massachusetts By Cutler Design, Inc. 43 Harvard Street Worcester, MA 01609 Rybak Engineering, Inc. -Fire Sprinklers Fire Protection Consultants 132 Forest Avenue Warren, Massachusetts 01083 Tel: (413) 436-5500 June 28, 2014 FIRE PROTECTION SYSTEMS NARRATIVE REPORTS 903.1.1 (1.a) BASIS (METHODOLOGY) OF DESIGN Buildings is an existing three story wood framed residential building to be converted to housing. SECTION 1 -Building Description a) Building "Use" Group Use Groups: Residential (see Section 310): Group R-2 b) Total square footage of building -4,900 c) Building height -36 d) Number of floors above grade -3 e) Number of floors below grade 1 f) Square footage per floor-1,300 (typical floor) g) Type(s) of occupancies (hazards) within the building -Residential h) Type(s) of construction VB i) Hazardous material usage and storage -none j) High storage of commodities within a building usually over 12 ft.-none SECTION 2 -Applicable Laws, Regulations and Standards a) Massachusetts State Building Code, 8th Edition, 780 CMR b) NFPA Standards and Edition used for design of each specific fire protection system NFPA 13R, Installation of Sprinkler Systems Residential to Four Stories, 2013 edition NFPA 72, National Fire Alarm Code, 2010 Edition NFPA 24, Installation of Private Fire Service Mains, 2002 edition SECTION 3 -Design Responsibility for Fire Protection Systems The fire sprinkler system design responsibility is described as: Fire Sprinkler System: Rybak Engineering and Carl C. Koslowski, PE fully designs (complete layout and calculations) and specifies the fire protection system or systems to be installed, reviews and approves the installing contractor's shop drawings. The PE is considered the engineer of record and certifies system installation for code compliance at completion. Fire Alarm System: See fire alarm plans. Overall Building Coordination: Cutler design is the professional of record and assumes responsibility for the coordination of each specific fire protection system requiring integration, forming an entire building life safety system. SECTION 4 -Fire Protection Systems to be installed a) Water supply, fire mains and hydrants New service from city main b) Automatic sprinkler systems and components Each floor will have individual zone controls. The third floor is unheated storage and will have a dry system. The l3R system is note required to have full sprinkler protection. -no coverage in porch, outside areas, or combustible concealed spaces. -closets are protected as an improvement beyond the code minimum d) See Shepherd Engineering Documents f) Seismic considerations -fire sprinkler system is fully braced for earthquake protection 903.1.1 (1.b) SEQUENCE OF OPERATION SECTION 1 WET SPRINKLER SYSTEM System operates automatically upon the fusing of a single fIre sprinkler. Operational Sequence: 1. The activation of a single sprinkler will discharge water and close the contacts of a vane type flow switch. 2. Closed contact on the flow switch will activate local electric bell (upon 30 second delay) and provide an alarm contact for the alarm control panel. DRY SPRINKLER SYSTEM System operates automatically upon the fusing of a single fIre sprinkler. Operational Sequence: 1. The activation of a single sprinkler will allow the air to exhaust the system and discharge water. 2. The dry valve will activate the system pressure switch. 3. Closed contact will activate local alarm indication including strobes, horns and bells. 4. Closed contact will send signal through local alarm panel to central station, central station will then notifY fIre department. GENERAL NOTE: all supervisory and alarm contacts are to be relayed to the fIre alarm panel. The main fIre alarm panel is required to be supervised by a central station service. FIRE ALARM SYSTEM Operational Sequence, Alarm: 1. Alarm condition in any alarm contact including smoke detector, heat detector, pull station, or fIre sprinkler flow switch will be identified at panel 2. Audible devices will indicate alarm condition. 3. Digital Dialer will relay alarm condition to COPS Monitoring Central Station. 4. Central Station must contact fIre department and owner Operational Sequence, Trouble or Supervisory: 1. Abnormal condition in any contact including tamper switch, low air, etc will identifIed at panel. 2. Digital Dialer will relay alarm condition to COPS Monitoring Central Station. 3. Central Station must contact the owner 903.1.1 (1.c) TESTING CRITERIA SECTION 1 -Testing Criteria FIRE SPRINKLER SYSTEM Hydrostatically test at a pressure of200 psi for two hours without a loss in pressure. Conduct forward flow test ofbackflow preventer at a rate of750 GPM. Opening of the inspectors test connection shall initiate an alann at the main frre alarm panel within 90 seconds. Hydrostatically test at a pressure of200 psi. Maximum leakage rate shall not exceed 1 quart per hour. Underground: Thoroughly flush at a rate of 400 GPM 2" drain test shall be conducted. Static and Residual pressures must be recorded on test certificate. Pnuematically test system at a pressure of 40 psi for 24 hr. Maximum pressure loss is I Yz psi Conduct system operational test from inspectors test connection. Local alann must sound within 90 seconds. Central station must receive alann and trouble signals. Working test of dry valve. Water delivery time to inspectors test: 60 seconds All supervisory switches shall be tested and shall register a trouble condition an the main alann panel. All alarm switches shall be tested and shall register an alarm condition an the main alann panel. FIRE ALARM SYSTEM See fire alarm narrative. SECTION 2 -Approval Requirements a) Rybak Engineering will provide a certificate of completion for the fIre sprinkler system only. b) Fire alarm contractor shall provide the fIre department with the fIre alarm system test results prior to the fIre department testing for occupancy. c) Approval of local authorities is required. d) The sprinkler contractor shall inform Rybak Engineering when the system piping is roughed in and prior to installation of the ceilings. e) Contractors must schedule a "rough" inspection with the Fire Department before piping and wiring is covered by the wall or ceiling. 1) Prior to scheduling a final acceptance test, documentation shall be submitted to the Fire Department certifying that the systems are installed in accordance with the codes and all components of the system have been tested. DEFINITIONS Fire Protection Systems Fire Protection Systems -Automatic sprinkler systems, fIre detection system, fire alarm notification system, smoke control system, kitchen hood suppression system, etc. Building Life Safety System Building Life Safety System -A combination of fIre protection systems and other building fire protection features such as automatic door closers, emergency generators, emergency egress lighting, elevator systems, etc., interconnected or integrated with multiple fIre protection systems functioning simultaneously when activated. Preparer of Narrative Report -An individual who has taken charge of a project and has knowledge of required and non-required fIre protection systems and buildings life safety systems. The designer in charge of a specific design for a fIre protection system may prepare their portion of the Narrative Report to be submitted to the individual who has "taken charge". The individual who has "taken charge" shall compile the data from the designer of each system and prepare a single, comprehensive and coordinated fmal Narrative Report describing each system and when applicable a description of how each system interlaces with the building life safety system's integration and sequence of operation. The take charge individual may be the architect, engineer of record, and the designer of any of the fIre protection systems or an independent qualified consultant.
