fire alarm notification system, smoke control system,kitchen hood suppression system,etc.
Building Life Safety System Building Life Safety System-A combination of fire protection systems and
other building fire protection features such as automatic door closers, emergency generators, emergency
egress lighting,elevator systems, etc.,interconnected or integrated with multiple fire protection systems
functioning simultaneously when activated.
Preparer of Narrative Report-An individual who has taken charge of a project and has knowledge of
required and non-required fire protection systems and buildings life safety systems.The designer in charge
of a specific design for a fire protection system may prepare their portion of the Narrative Report to be

independent qualified consultant.
903. 1.1 (1.c) TESTING CRITERIA
SECTION 1 -Testing Criteria
FIRE SPRINKLER SYSTEM
Hydrostatically test at a pressure of 200 psi for two hours without a loss in pressure.
Opening of the inspectors test connection shall initiate an alarm at the main fire alarm panel within
90 seconds.
Conduct forward flow test of backflow preventer at a rate of 400 GPM.
2"drain test shall be conducted. Static and Residual pressures must be recorded on test certificate.
All supervisory switches shall be tested and shall register a trouble condition an the main alarm
panel.
All alarm switches shall be tested and shall register an alarm condition an the main alarm panel.
FIRE ALARM SYSTEM
A full test of the fire alarm system shall include working tests of: water flow switches, tamper
switches,pull stations, and indicating appliances.
All tests shall be performed in accordance with manufacturer's requirements and NFPA 72.
Fire department shall witness test of fire alarm communicator and receipt of fire alarm signal at
station shall be tested.
All audible devices shall provide the highest of each of the following(at 5'0 aff):
- 75 dBA at 10 ft
- 15 dBA above ambient sound level
- 5 dBA above maximum 60 second sound level.
SECTION 6 -Special Consideration and Description
The fire alarm system provided exceeds the requirements of 780 CMR by providing manual pull stations.
Only audio and visual notification appliances are required by 906.5.
903. 1 .1 (1.b) SEQUENCE OF OPERATION
SECTION 1
WET SPRINKLER SYSTEMS
System operates automatically upon the fusing of a single fire sprinkler.
Operational Sequence:
1. The activation of a single sprinkler will discharge water and close the contacts of a vane type flow
switch.
2. Closed contact on the flow switch will activate fire alarm system(upon 30 second delay)and initiate
the audio/visual devices. (see below)
FIRE ALARM SYSTEM
Water Flow,Manual Pull Station,or Egress Corridor Smoke Detectors
I. Activation of the fire alarm system into alarm mode can be achieved by sprinkler water flow,manual
pull station,or smoke detector.
2. Upon alarm activation,the following will occur:
- Business occupancy indicating appliance circuit will be activated
- Residential occupancy indicating appliance circuit will be activated
- Fire Department will be notified by the control panel communicator.
Multi-Station Smoke Detection
1. Smoke detection in the Residential units will activate the local smoke alarms but will not activate the
building fire alarm system.
2. In the event of fire,if the fire sprinklers within the residential unit are activated,the full building fire
alarm system will be activate.
SECTION 3— Design Responsibility for Fire Protection Systems
A professional engineer(PE)provides a partial design and specifies the design criteria to be used by the
installing contractor who finalizes the system layout,provides calculations to confirm the design criteria.
The PE reviews and approves the installing contractor's final layout and calculations. The PE is considered
the engineer of record and certifies system installation for code compliance at completion.
SECTION 4 - Fire Protection Systems to be installed
a) Water supply,fire mains and hydrants—the building was previously equipped with a sprinkler system
and the existing fire service will service the new sprinkler system.
b) Automatic sprinkler systems—Complete sprinkler protection will be provided by(2)fire sprinkler
zones. Individual zones will be provided for the Business and Residential Occupancies.
c) Standpipe systems and components—none required
d) Fire alarm systems and components—A fire alarm system is provided to comply with 906.5 which
requires approved audible and visual fire alarm devices. This system exceeds the minimum
requirements of 780 CMR by providing manual pull stations and smoke detection in the egress
corridors. The indicating appliances will sound an alarm with the activation of any of the following;
the sprinkler system(which covers the entire building),the manual pull stations, and the smoke
detectors located in the egress corridors.
Smoke detection is provided at the request of the building department.
In addition to the building fire alarm system,multiple station smoke detection is provided within the
residential unit.
e) Automatic fire extinguishing systems -none
f) Manual suppression systems-none
g) Smoke control/management systems-none
h) Kitchen cooking equipment and exhaust systems -none
i) Emergency power equipment-none
j) Hazardous material monitoring equipment-none
k) Seismic considerations—all fire safety systems and the building structure are to be designed for
seismic loads.
SECTION 5 - Features Used in the Design Methodology
a) Building occupant notification and evacuation procedures
The building fire alarm system monitors the building fire sprinkler system and manual pull stations.
Activation of these initiating devices will activate a building wide fire alarm and require complete
building activation.
Multiple station smoke detection will provide local fire alarms for the residential unit only. However,
if a fire sprinkler activates in the residential unit,the building fire alarm system will be activated.
b) Emergency response personnel,site and systems features
A Knox-Box is located at the entrance canopy. This key location is marked by an external beacon.
The fire alarm control panel is located in the common space of the entry corridor.
i
FIRE PROTECTION SYSTEMS NARRATIVE REPORTS
The interaction of fire protection systems can be extremely complex. The detection of a fire in a building
by an automatic device may be designed to initiate other life saving fire protection systems or devices,or
other mechanical systems. In some circumstances different individuals or different companies may design
safety systems, which are required to interact.The narrative report is intended to provide a single
document, which describes the design rationale of all fire protection systems and the interface between
systems.
The existing building is being converted from an existing dry cleaner to a multi-tenant office space. These
office spaces are not currently defined. New tenants may require modifications to the building that will
require review for conformance with 780 CMR.
The second floor is intended to become a single-family residential unit. This unit may be sold as a
condominium.
903. 1.1 (1.a) BASIS (METHODOLOGY) OF DESIGN
