Sprinkler Design Methodology The building will be provided with an automatic sprinkler system. The building is designed as per NFPA 13. A dedicated fire service including a vertical double check valve assembly and wet pipe alarm check valve to serve the building. The building shall be provided with a fire department connection. The building shall be protected by quick response pendent, upright or sidewall sprinkler heads. New sprinklers heads and branch piping will be supplied from the new fire service valves. The new heads will be designed in configuration with the new architectural ceiling plans. All common areas shall be protected with a wet sprinkler system employing concealed heads designed to deliver a minimum density of 0.10 GPM/sf. over the most hydraulically remote 1,500 sq. ft. The mechanical room, and storage areas shall be protected with a wet sprinkler system designed to deliver a minimum density of 0.15 GPM/sf. over the most hydraulically remote 1,500 sq. ft. The sprinkler systems shall be designed in accordance with NFPA #13. Final acceptance for the sprinkler system will consist of the following: The sprinkler system is to be pressure tested to 200 psi and all inspector’s test valves are to be operated to ensure all monitor switches and activation alarms operate properly. All tests are to be done in accordance with all applicable NFPA requirements. This contractor shall be responsible to develop complete hydraulic calculations for the Fire Protection Systems as shown on the engineer’s drawings. This contractor shall perform his own flow test at building and base his calculations on the flow test results. Flow test results and hydraulic calculations are to be submitted to the Fire Department for review and comments. 2 Fire Alarm System Methodology An addressable manual and automatic fire alarm system will be provided.

Strobes will be provided in toilet rooms, locker rooms and conference rooms. A connection will be provided to flow and tamper switches. The sequence of operation of the fire alarm systems will be as follows: 1) The activation of any manual fire alarm pull station or the automatic actuation of any detector, or any other alarm initiating device shall result in the following: (a) The device in alarm will display on the fire alarm control panels. (b) The evacuation horns will automatically sound a temporal code, and the strobes will flash. (c) Mechanical equipment provided with duct smoke detectors will shut down. (d) In the event of a commercial power failure, the fire alarm control panels shall immediately and automatically transfer to a stand-by battery source, capable of supervising the system for 60 hours. (e) A signal will be sent to the local fire department via the the central monitoring station. Final system acceptance for the fire alarm system will consist of the following: 3 1) The system will be accepted only after a satisfactory test of the entire system has been accomplished by a factory-trained distributor in the presence of a representative of the Authority Having Jurisdiction and the Owner’s representative. Upon completion of a successful test, the Electrical Contractor shall so certify in writing to the Owner. 2) The distributor shall provide the on-site service of an authorized, factory-trained technical representative to supervise all connections and fully test all devices and components of the system during installation phase. 3) The distributor shall provide comprehensive training on the operation, proper use and testing of the installed fire alarm system to the building Owner’s representative. 4) The Electrical Contractor shall warranty the complete fire alarm system, wiring and equipment to be free from inherent mechanical and electrical defects for a period of one (1) year from the date of the completed and certified test or from the date of the first beneficial use.
