FIRE PROTECTION FIRE SYSTEMS NARRATIVE REPORTS
903. 1.1 BASIS (METHODOLOGY) OF DESIGN
Section 1.1 (1.a) Existing Building Description
The existing building at 65 Federal St. is a five unit/family, three story, plus basement
structure. The use group of this facility, as defined in 780 CMR is R1 Residential,
constructed with combustible materials. Basement will also be used for residential
occupancy. The existing building's total area is approximately 5,150 sq. ft., including
basement.
SECTION 2 — Applicable Laws, Regulations and Standards
a) The Massachusetts State Building Code 9th Edition, 780 CMR Chapter 9,
"Fire Protection System Requirements"
b) NFPA Standards and Editions used for the design of each fire protection
system:
NFPA 13R, Installation of Sprinkler Systems in Residential multifamily
dwellings, 2013 Edition
NFPA 13, Installation of Sprinkler Systems, 2013 Edition.
NFPA 25, Inspection, Testing and Maintenance of Sprinkler Systems, 2007
Edition.
c) M.G.L. Chapter 146 and Chapter 148.
SECTION 3 — Design Responsibility for Fire Protection Systems
a) This project is developed under the following design responsibility:
The Design Build Sprinkler Contractor (Diablo Fire Protection LLC) and the Fire
Protection Professional Engineer (Jason C. Kahan, MA Registration # 48388) fully
designs (complete layout and calculations) and specify through construction management
collaboration, the fire protection system or systems to be installed. The Design Build
Professional Engineer reviews and approves the completed shop drawings for code
compliance. The Design Build Professional Engineer is considered the engineer of record
and certifies system installation for code compliance at completion.

SECTION 4 — Fire Protection Systems to be installed
SPRINKLER SYSTEM DESCRIPTION
The new sprinkler system will be as follows:
a) Mech Rm.; blk. steel pipe with CI Trd. fittings and commercial sprinklers.
b) All residential areas; CPVC piping with CPVC glued type fittings and residential style
sprinklers. A flow switch will be installed and wired to local smoke detectors, outdoors
electric bell as well to a dialer alerting the Fire Dept.
WATER SUPPLY
New 1 1/2" or larger, fire protection underground copper pipe will be installed
from the city water main into the basement.
FIRE ALARM SYSTEMS AND COMPONENTS
The flow switch and tamper switches will be connected, by others, to the house fire alarm
and/or smoke detection system. For further description please see the "Fire Alarm
Narrative"
SECTION 5 — Fire Protection Systems Design Methodology
This building will be protected with a NFPA 13R wet sprinkler system installed in
accordance with 780 CMR TAB 903.2, as modified and permitted for 4 family dwellings.
903. 1.1 (1.b) SEQUENCE OF OPERATION
Section 1
WET SPRINKLER SYSTEM System operates automatically upon the fusing of a single
fire sprinkler.
(continue)
P4
1. Activation of a single sprinkler will drop the pressure in the system, activating a
low pressure switch, which in turn will start-up the fire pump.
2. A water will discharge from the open sprinkler(s) activating the system flow
switch.
3. Activation of this flow switch will "set off' a local horn and strobe and/or smoke
detectors, and send an alarm to the Fire Dept. Station .
903. 1.1 (1.c) TESTING CRITERIA
Section 1
Upon completion of the sprinkler system, the system shall be tested
hydrostatically for 2 hours at 200 PSI by Arkon fire Protection Co. Inc.
and witnessed by the General Contractor, the owner's Representative and, if
desired, the Salem Fire Department.
Upon final completion of the sprinkler, the sprinkler foreman and /or contractor
will arrange final sprinkler inspection with the Fire Department.
Section 2
The sprinkler system shall be tested and inspected thereafter by -annually, by a
licensed sprinkler company
Section 3
Upon final testing completion, all sprinkler closeout documents such as as -built
drawings, Operation & Maintenance Manuals, and copies of the Material Letter
of Compliance and Test Certificates will be forwarded to the Fire Department
and building owner. The building owner's facility personnel will
be trained (as necessary) on system operations immediately thereafter, prior to
occupancy.
