SECTION 3: Design Responsibility for Fire Protection Systems
The construction documents include a preliminary fire protection system design and design criteria to be
used by the installing contractor who will finalize the system layout and provide calculations and working
plans based on the design criteria. The contractor’s Fire Protection Engineer (or certified designer, where
acceptable by law) is responsible for submitting working plans (shop drawings) and calculations to the
authority having jurisdiction for approval prior to the start of construction. The engineer of record will
review the installing contractor’s working plans and calculations for compliance with the design criteria.
The engineer of record and will submit an affidavit for general code compliance at the completion of
construction.
The requirements for progress inspections by the Fire Department and final acceptance test
documentation should be arranged through and addressed by the Fire Alarm Testing Vendor and the
General Contractor.
SECTION 4: Fire Protection Systems to be Installed
1. Water Supply: Existing system shall remain
2. Automatic Sprinkler Systems: The existing wet sprinkler system shall be modified to accommodate
the renovation. Project includes selective removal of sprinkler heads in suspended ceilings and
piping modifications to accommodate the new floor plan. Where suspended ceilings are removed
during selective removal, new upright sprinkler heads will provide protection during construction.
3. Standpipe Systems: The existing Class I Wet Manual Standpipe System will remain. A new fire hose
valve will be added at the new ED entrance.
4. Fire Alarm Systems and Components:
a. Fire Alarm Control Panel: New fully addressable, programmable fire alarm annunciator with
electronic modules, circuits and battery backup. The panel is located in the existing Security
Office near the Emergency Department.
b. Manual Pull Stations: Single action unit with key operated station reset.
c. Initiation Devices: Devices include addressable photoelectric smoke detectors, duct smoke
detectors and heat detectors.
d. Notification Devices: Annunciation devices shall be installed throughout the
addition/renovation area to meet NFPA and ADA requirements and shall be integrated with
the existing tone/voice alarm system.
5. Automatic Fire Extinguishing Systems: Not Applicable
6. Manual Suppression Systems: Not Applicable

SECTION 5 - Features Used in the Design Methodology
Evaluation of the existing water supply is required in order to confirm that it is sufficient for the proposed
renovation and the current design criteria. The fire protection contractor will be responsible for
performing a fire hydrant flow test to update the flow test data for calculations related to this project.
1. A fire hydrant flow test was conducted by Rybak Engineering with the following results:
Date: 2015
Static Pressure: 85 PSI
Residual Pressure: 75 PSI
Flow Rate: 1040 GPM
2. Emergency Response Personnel, Site Systems Features: Fire department access to existing
3. The following safeguards shall be implemented during the system construction.
a. All welding safeguard procedures shall be followed as outlined in NFPA 13 and/or local
standards and permit requirements.
b. Local and national OSHA requirements shall be followed regarding worker safety in the
construction areas.
c. Methods for future testing and maintenance of systems and documentation:
1) NFPA 25 "Standard for The Inspection, Testing, and Maintenance of Water Based Fire
Protection Systems" shall be followed by the building owner.
SECTION 6 - Sequence of Operation
The fire alarm system is to monitor manual pull stations and automatically activated devices such as
sprinkler flow switches, smoke detectors, or duct smoke detectors. The fire alarm system is designed so
that upon activation of a fire alarm initiating device, all fire alarm indicating devices will simultaneously
activate to notify occupants. Notification devices consist of tone type audio/visual units and strobe type
visual units.
Activation of any manual pull station, flow switch or smoke detector in common areas will immediately
and simultaneously activate all tone and visual units and transmit an alarm signal. In addition,
identification will occur at the FACP, identifying the device originating the alarm. The activation will also
recall the elevator, shut down fans, and record the event in the system memory.
The valve tamper, pressure, and flow switches at the main fire service entrances and on the sprinkler are
monitored by the Fire Alarm Control Panel (FACP). Alarm shall be sent to the local fire department
through a radio box and antenna.
The Air Handling Units (AHUs) will have duct smoke detectors on the supply and the return units. Each
unit will have smoke and/or smoke/fire dampers on the unit. Upon detection of smoke, the detector shall
initiate a shutdown of the AHUs and send a signal to the fire alarm control panel.

Section 7 - Testing Criteria
All features, devices, and components shall be tested for acceptance in accordance with NFPA 3, 13, 24,
25 and 72 requirements. Sprinkler and riser pressure and flow switches shall be tested for signal
transmission to the building FACP by flowing water through the inspector’s test connections. All valve
supervisory switches shall be tested by closing valves to verify transmission of trouble signals to the FACP.
Smoke detectors shall be activated using a magnet, or with approved canned smoke for duct detectors,
per the manufacturer’s recommendations, and all pull stations shall be activated by opening, and upon
activation of each device, the proper operation of the fire alarm system shall be checked for proper
operation including annunciation at the fire alarm control panel and transmission of an alarm signal to
Main Operator’s Switchboard. Proper operation in the emergency power mode shall be demonstrated as
well as a check of supervision circuits for opens and shorts.
Section 8 - Approval Requirements
The following approval requirements shall be adhered to as a part of the "Close-Out" documents for the
Code Officials’ department records:
1. Third party fire alarm acceptance test to be performed prior to scheduling the Randolph Fire
Department.
2. The AHJ shall be notified prior to any system testing being conducted.
3. Establish method of approval required (verbal or written) from Code Official if system satisfied all
operational code compliance requirements.
4. Establish method of remedial action when a system or portion of a system fails to operate
satisfactorily.
5. Documentation to be submitted to Code Officials at completion, verifying that systems are in
compliance with all laws, regulations and standards, as well as pre-approved narrative reports along
with the Fire Alarm Matrix.
