STATEMENT OF PURPOSE The following report is prepared in accordance The International Building Code (IBC 2015), International Building Code (IEBC 2015), 527 CMR with the Massachusetts State Building Code, 780 CMR 9th Edition. The content is limited to systems contained within or installed specifically to service the life safety and fire protection systems of the existing, renovated residential ‘R2’ use East & West Residential Wings for the Wise Independent Living Facility at 822 Main Street South Yarmouth, Massachusetts. The intent of this report is to provide a written summary description of the proposed applicable fire protection systems and operational features. This report explains the methodology used to design the fire protection system for the protection of occupants of the space, within the scope of this project. B. SYSTEM NARRATIVE a) Automatic Sprinkler System. The proposed automatic fire protection sprinkler systems will consist of a wet pipe sprinkler system and dry pipe sprinkler system. 1. The proposed automatic wet pipe sprinkler systems will be designed per NFPA 13 (2013) as follows: East & West Residential Wings First & Second Floors NFPA 13 residential design to provide 0.10 gpm per square minimum discharge from the hydraulically most remote 4 sprinklers in a dwelling unit plus 100 gpm for hose stream allowance. Sprinklers will be installed throughout the entire building including all combustible spaces. 2. The proposed automatic dry pipe sprinkler systems will be designed per NFPA 13 (2013) as follows: East & West Wings mansard roof addition combustible concealed space - Light Hazard NFPA 13 design to provide 0.10 gpm per square minimum discharge from the hydraulically most remote 2535 square feet plus 100 gpm for hose stream allowance. Sprinklers will be installed throughout the entire building including all combustible spaces. The systems will be supplied from the existing 6” sprinkler riser located in the basement level. The existing main sprinkler riser consists of a 6” double check valve backflow preventer, 6-inch riser check valve, 2-inch main drain and 6-inch water flow switch, 6” dry pipe valve, air compressor and main drain. A new 6” wet riser will be added with two additional dry pipe system risers An existing 2-1/2” x 2-1/2” x 4” fire department connection is located on the east side rear of the of the existing A2 Use building. An existing post indicator valve is located outside the building at the existing 6” fire service on the East Residential Wing. 3. The water supply to the automatic sprinkler system consists of the city water supply. A hydrant flow test was conducted on 11/8/2022 on the property at 822 Main Street by Balldon Fire Protection, Inc. Test results are as follows: Static 72 psi, Residual 66 psi, Total Flow 1,277 gpm. b) Fire Alarm System 1. The existing fire alarm system will upgraded and modified for sprinkler water flow alarm and supervisory devices with modules for integration of the fire alarm system in the entire building. New visual and audio/visual alarms will be ADA compliant type and located throughout the facility. With initiating devices for both alarm and supervisory conditions for the new sprinkler systems being added in the renovated east and west residential buildings. A new wet sprinkler system riser with individual floor control assemblies consisting of a water flow switch and control valve for the first and second floor of both wings. Two dry systems will be added with pressure flow switches and supervisory Wise Independent Living Facility 822 Main Street South Yarmouth, MA 4 air pressure switches in the attic. Any switch installed on the sprinkler system will be interconnected into the main building fire alarm system for supervision and notification purposes. 2. Applicable Laws, regulations, standards and testing requirements to be followed are MGL Chapter 148, MA State Building Code, 9th ed. (780 CMR Chpt.9), NFPA 72 2013 ed. and CMR 527. 3. The fire alarm system will be a monitored all call signaling system. Any activation of a pull station, smoke detector or water flow will put an alarm signal on fire panel which will activate all horn/strobe, strobe only and low frequency horn devices throughout entire building. The Remote Supervisory Station will then notify the Yarmouth Fire Department, building owner and the Central Station Alarm Monitoring Company. The building will be monitored via Fire Alarm Company with a Radio Communicator or cellular communicator, depending on signal strength near completion of installation. 4. Visual and audio/visual alarms including where required will be ADA compliant type and located throughout the building. Smoke detectors/CO detectors will be provided where required throughout the building, ADA compliance for heights will be adhered to in the all areas throughout entire building, new water supervisory tamper switches and flow switches will be installed on the new sprinkler system risers in sprinkler valve room located in the basement. Activation of any of the initiating devices shall cause activation of the audio/visual components of the system as well as the appropriate signal transmission to the local fire department. Activation of any water flow switch will initiate an alarm signal at the fire alarm control panel and transmit to the Yarmouth Fire Department local alarm will be initiated through activation of the electric bell and A/V devices throughout the building. All tamper switches when activated will transmit supervisory signals to the fire alarm control panel for building notification local alarm will be initiated through activation of the electric bell and A/V devices throughout the building.
