Section 3 – Design Responsibility for Fire Protection Systems:
a) The Fire Protection Engineer (or P.E. with demonstrated fire protection design experience) 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. The fire protection engineer of record for this job is Scott
Henderson (Mass. FPE license #46553).
Section 4 – Fire Protection Systems to be installed:
a) Water supply and hydrant:
Water supply information.
Static Pressure: 89 psi
Residual Pressure: 82 psi
Flow: 1350 gpm
b) Automatic sprinkler system and components:
New Building has a 6” fire service, 4” double check valve assembly, and one 4” manifold valve. Sprinklers shall
consist of quick response brass upright and chrome pendent throughout.
c) Standpipe system and components:
Page 2 of 4
This building does not require a standpipe system, per 780 CMR.
d) Fire alarm system:
The building will include a fire alarm system and done by others.
e) Automatic fire extinguishers:
The building will not include any automatic fire extinguishing system, other than sprinklers.
f) Manual fire extinguishers:
Manual fire extinguishers are provided throughout the facility in accordance with NFPA 10. (By Others)
g) Smoke control/management systems:
The spaces do not require a smoke control or exhaust system.
h) Kitchen cooking equipment and exhaust systems:
The spaces do not possess any kitchen cooking equipment and therefore an exhaust system is not required.
i) Hazardous material monitoring equipment:
There is no hazardous material stored on site; therefore, no monitoring equipment is required.
Section 5 – Features used in the Design Methodology:
a) All construction work will be performed in a manner that is safe and in compliance with applicable Codes.
b) All testing shall be conducted in accordance with NFPA 25 and NFPA 13. This will include testing of 100% of
all components. Any device/appliance found to be faulty shall be replaced. All testing will be coordinated with the
Fire Department prior to initiation of test. All sprinkler main/branch line flushing will be done by the Sprinkler
Contractor.
c) Intent of sprinkler system design: Control/extinguish fire throughout the proposed building.
d) All systems are to be maintained per the requirements of 780 CMR, NFPA 25, NFPA 72, and the requirements of
the Fire Department.
Section 6 – Special Consideration and Description:
At this time, the Designer does not require a Waiver or Variance. The Fire Protection Design is in accordance with
780 CMR.
1.b. Sequence of Operation:
Section 1:
In the event of a fire, one or more sprinklers will operate. The installed network of piping will supply water to the
operating sprinklers.
When a sprinkler operates (fuses), the flow of water will activate the flow switch and the existing electric bell will
sound. The flow switch will send an electric signal to the alarm panel, simultaneously sending an alarm (installed by
others) to the fire department and will sound an audible alarm within the building alerting the occupants. The
building is not equipped with a standpipe system.
To increase sprinkler system pressure, the fire department will be able to connect hoses from a pumper truck to the
existing fire department connection, located as indicated on the Project Drawings.
1.c. Testing Criteria:
Section 1 – Testing Criteria:
Personnel:
Page 3 of 4
a) The General Contractor in association with the Electrical and Fire Protection Contractor will coordinate the
actual test dates. This date will be based upon completion of installation of all components.
b) Upon completion of a successful pre-test, the Contractor shall notify the Professional in Charge that all systems
are ready for a final test. The Contractor will provide the professional with documentation that all equipment was
100% tested and that the system is ready for a final acceptance test. As part of the pre-test, the Contractor shall
ensure that graphic annunciator has been updated to reflect all changes performed under the contract.
c) Upon receipt of the aforementioned confirmation letter, the Professional in Charge will direct the Construction
Manager to proceed with notifying all interested parties (Contractors, Distributors, and Code Officials) that all Life
Safety systems passed a pre-test and are ready for a final test. The construction manager will then proceed to
coordinate a mutually agreeable time for all parties to witness the final test. Affidavit will be presented to the fire
department at the time of final testing.
d) Sprinkler system piping feeding tenant space shall be tested, certified and flushed prior to connection of any in-
store piping.
e) The Owner shall continue the contractual engagement of the licensed Sprinkler Contractor to perform regular
system maintenance and testing as required by the 780 CMR and NFPA-25.
Section 2 – Equipment and Tools:
a) All equipment required to perform a 100% test of the fire protection and detection system will be furnished by
the Contractor. This equipment shall be available at the time of the test. A listing of the equipment that is to be
supplied will be forwarded to all “Final Test participants” prior to the test occurring so as to allow for comments.
Typical equipment supplied would include the following:
Manufacturer’s instructions
Approved Narrative Report, sequence of operation section
Flow measuring devices
Gauges
Fire Department equipment
Special tools
Section 3 – Approval Requirements:
a) Upon viewing a successful test of all fire protection and fire detection equipment, the Code Official(s) shall “sign
off” on the Building Department Inspection Card. This act will confirm the Code Official has witnessed the test and
accepts the building as satisfactorily complete.
b) In the event a piece of equipment fails the final test; the affected Contractor will make a reasonable effort to
replace the defective equipment immediately so the test may continue. In the event this action is not possible; the

rescheduling the test with all attendees.
c) Upon successful completion of all tests, the Contractors and Distributors will provide documentation attesting to
