The responsibility of the Architect and Engineer include review of the drawings,materials, and installation in accordance with the contract documents;review and approval of quality control procedures; present at intervals appropriate to the stage of construction to be familiar with the progress and quality of the work and to determine if the work is beig performed in accordance with the construction documents. Upon completion of the project,Rybak Engineering will submit an affidavit stating: To the best of my knowledge,information, and belief,the fire sprinkler and fire alarm systems were constructed in general conformance with the plans and specifications, and in my professional opinion,is in compliance with applicable laws, codes, and ordinances. 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 final Narrative Report describing each system and when applicable a description of how each system interfaces 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. 903. 1.1 (1.c) TESTING CRITERIA SECTION 1 -Testing Criteria FIRE SPRINKLER SYSTEM Hydrostatically test at a pressure of 200 psi for two hours without a loss in pressure. Opening of the inspectors test connection shall initiate an alarm at the main fire alarm panel within 90 seconds. Conduct forward flow test of backflow preventer at a rate of 400 GPM. 2"drain test shall be conducted. Static and Residual pressures must be recorded on test certificate. All supervisory switches shall be tested and shall register a trouble condition an the main alarm panel. All alarm switches shall be tested and shall register an alarm condition an the main alarm panel. FIRE ALARM SYSTEM A full test of the fire alarm system shall include working tests of: water flow switches, tamper switches,pull stations, and indicating appliances. All tests shall be performed in accordance with manufacturer's requirements and NFPA 72. Fire department shall witness test of fire alarm communicator and receipt of fire alarm signal at station shall be tested. All audible devices shall provide the highest of each of the following(at 5'0 aff): - 75 dBA at 10 ft - 15 dBA above ambient sound level - 5 dBA above maximum 60 second sound level. SECTION 6 -Special Consideration and Description The fire alarm system provided exceeds the requirements of 780 CMR by providing manual pull stations. Only audio and visual notification appliances are required by 906.5. 903. 1 .1 (1.b) SEQUENCE OF OPERATION SECTION 1 WET SPRINKLER SYSTEMS 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 fire alarm system(upon 30 second delay)and initiate the audio/visual devices. (see below) FIRE ALARM SYSTEM Water Flow,Manual Pull Station,or Egress Corridor Smoke Detectors I. Activation of the fire alarm system into alarm mode can be achieved by sprinkler water flow,manual pull station,or smoke detector. 2. Upon alarm activation,the following will occur: - Business occupancy indicating appliance circuit will be activated - Residential occupancy indicating appliance circuit will be activated - Fire Department will be notified by the control panel communicator. Multi-Station Smoke Detection 1. Smoke detection in the Residential units will activate the local smoke alarms but will not activate the building fire alarm system. 2. In the event of fire,if the fire sprinklers within the residential unit are activated,the full building fire alarm system will be activate. SECTION 3— Design Responsibility for Fire Protection Systems A professional engineer(PE)provides a partial design and specifies the design criteria to be used by the installing contractor who finalizes the system layout,provides calculations to confirm the design criteria. The PE reviews and approves the installing contractor's final layout and calculations. The PE is considered the engineer of record and certifies system installation for code compliance at completion. SECTION 4 - Fire Protection Systems to be installed a) Water supply,fire mains and hydrants—the building was previously equipped with a sprinkler system and the existing fire service will service the new sprinkler system. b) Automatic sprinkler systems—Complete sprinkler protection will be provided by(2)fire sprinkler zones. Individual zones will be provided for the Business and Residential Occupancies. c) Standpipe systems and components—none required d) Fire alarm systems and components—A fire alarm system is provided to comply with 906.5 which requires approved audible and visual fire alarm devices. This system exceeds the minimum requirements of 780 CMR by providing manual pull stations and smoke detection in the egress corridors. The indicating appliances will sound an alarm with the activation of any of the following; the sprinkler system(which covers the entire building),the manual pull stations, and the smoke detectors located in the egress corridors. Smoke detection is provided at the request of the building department. In addition to the building fire alarm system,multiple station smoke detection is provided within the residential unit. e) Automatic fire extinguishing systems -none f) Manual suppression systems-none g) Smoke control/management systems-none h) Kitchen cooking equipment and exhaust systems -none i) Emergency power equipment-none j) Hazardous material monitoring equipment-none k) Seismic considerations—all fire safety systems and the building structure are to be designed for seismic loads. SECTION 5 - Features Used in the Design Methodology a) Building occupant notification and evacuation procedures The building fire alarm system monitors the building fire sprinkler system and manual pull stations. Activation of these initiating devices will activate a building wide fire alarm and require complete building activation. Multiple station smoke detection will provide local fire alarms for the residential unit only. However, if a fire sprinkler activates in the residential unit,the building fire alarm system will be activated. b) Emergency response personnel,site and systems features A Knox-Box is located at the entrance canopy. This key location is marked by an external beacon. The fire alarm control panel is located in the common space of the entry corridor. i FIRE PROTECTION SYSTEMS NARRATIVE REPORTS The interaction of fire protection systems can be extremely complex. The detection of a fire in a building by an automatic device may be designed to initiate other life saving fire protection systems or devices,or other mechanical systems. In some circumstances different individuals or different companies may design safety systems, which are required to interact.The narrative report is intended to provide a single document, which describes the design rationale of all fire protection systems and the interface between systems. The existing building is being converted from an existing dry cleaner to a multi-tenant office space. These office spaces are not currently defined. New tenants may require modifications to the building that will require review for conformance with 780 CMR. The second floor is intended to become a single-family residential unit. This unit may be sold as a condominium. 903. 1.1 (1.a) BASIS (METHODOLOGY) OF DESIGN SECTION 1 - Building Description a) Building"Use"Group—Mixed Use, (B)usiness/(R3)Residential b) Total square footage of building 12,000 sq ft c) Building height—22'0 d) Number of floors above grade-2 e) Number of floors below grade- 1 f) Square footage per floor Basement= 1,590 First floor=6,250 Second floor=4,160 g) Type(s)of occupancies(hazards)within the building, office tenant space, storage vault,residence h) Type(s) of construction—Brick/Masonry Walls with wood joist framing i) Hazardous material usage and storage—none known. j) High storage of commodities within a building usually over 12 ft.—none allowed k) Site access arrangement for emergency response vehicles SECTION 2 -Applicable Laws, Regulations and Standards a) 780 CMR code sections"Fire Protection System Requirements" - 904.2—Fire suppression system - 915.0—Fire Dept Connections - 916.0—Yard Main - 919.0 —Multiple Station Smoke Detection - 920.0—Fire Extinguishers - 923.0—Supervision b) NFPA Standards and Edition used for design of each specific fire protection system - NFPA 13, 1996 edition"Installation of Sprinkler Systems" - NFPA 72, 1996 edition"National Fire Alarm Code" Fire Protection Construction Documents Narrative Report for Twin Cleaners Building 211 North Street Northampton,Massachusetts By Design Team Ford Gillen Architects - Architect Rybak Engineering—Fire Sprinklers/Fire Alarm October 28, 2001 FIRE ALARM CONTROL PANEL LOCATED 15 FEET TO THE RIGHT OF THE MAIN ENTRANCE DOOR, ACROSS FROM STAIR.
