CSI Engineering LLC, is responsible for the Fire Alarm System. CSI Engineering LLC, will perform a final
walk-through and sign-off. CSI Engineering LLC, shall review the installation and shall confirm that the
installation complies with the contract documents and applicable codes.
Desian:
The design was based on applicable sections of 780 CMR Massachusetts State Building Code (latest
edition), applicable provisions of NFPA 1, 13, 24, 25, 72, 90A 92A and 101, applicable sections of 527
CMR and 527 CMR 12, Applicable sections of 521 CMR, and other local state &federal laws as
applicable.
Desiqn Methodoloqv:
Fire Suppression
The existing fire suppression system water service, a 6" fire main. The existing backflow preventor
assembly, fire department connection, and mains, shall remain unchanged. The latest flow test data
available from 05/02/17 from Hayes Engineering.is 90 PSI static with 88 PSI residual while flowing 1403
GPM.
Sprinkler systems in the new addition areas shall provide 100% coverage and in general be as follows:
A new 4"sprinkler main has been tapped off of the existing 4"sprinkler main. The new zone for the
addition will have an isolation valve and flow switch.
Offices, toilet rooms, and similar occupancies shall meet the requirements of Light Hazard Occupancy
with a density of 0.10 GPM per square foot over the hydraulically most remote 1,500 square feet.

Portsmouth,NH 03801 Tel#(603)319-8244 Web: www.csi-engineers.com
Manufacturing area, mechanical rooms and similar occupancies shall meet the requirements of Ordinary
Hazard Group 1 Occupancy with a density of 0.15 GPM per square foot over the hydraulically most
remote 1,500 square feet.
Existing building work will consist of relocated heads to meet the new layout and provide proper sprinkler
coverage.
There will be two 2 '/z"fire department valves provided for fire department hose connections, as shown on
the dwgs.
Fire Alarm
It is our intent to install a new addressable fire alarm control panel in the new addition space. Smoke
detection is not required throughout the entire space as all of this space shall be fully sprinkler protected.
Addressable pull stations are provided at all exits and stairways. The notification in all areas shall be via
audio/visual units. Duct smoke detectors shall be provided at all rooftop units above 2,000 CFM. These
devices will be connected to the detection/initiation loop on the new addressable FACP. The new
addressable fire alarm control panel will tie into an existing conventional control panel through spare
zones that provides coverage to the rest of the building. An annunciator display will be located by the fire
department.
Sequence of operation:
Fire Suppression
Wet Pipe Automatic Sprinkler System: Heat produced from a fire melts the fusible link or glass bulb on a
single sprinkler head or group of sprinkler heads causing the sprinkler(s) to open. Water from the water
filled pipe is discharged immediately from the sprinkler head(s) to control the fire. The fire department
may pump the fire department connection to supplement the system. Sprinkler system water flow alarms
activate upon system flow and indicate to the FACP an alarm condition. The sprinkler(s) continue to flow
water until manually shut off.
Fire Alarm
1. The operation of a manual station or activation of any automatic alarm initiating device
(smoke, heat, waterflow or deluge water flow) shall automatically:
a) Sound all audible devices in the building.
b) Flash all visual signals throughout the building in a synchronized fashion.
c) Flash an alarm LED and sound an audible signal at the FACP. Upon
acknowledgement, the alarm LED shall light steadily and the audible shall
silence. Subsequent alarms shall re-initiate this sequence.
d) Initiate the transmission of an alarm to the local Fire Department via the
coordinated transmitting means.
e) Visually indicate the alarm initiating device type and location via the LCD display
located at the FACP.
f) Visually annunciate on all system annunciators the initiating device type and
location.
g) Activate the outside weatherproof beacon.
h) Record the alarm in the event history log, and print a record of the alarm on the
system printer where applicable.
i) Activate prioritized output relays to shut down affected supply and return air
handlers.

j) The elevator recall function shall operate as follows:
(1) Smoke detectors in elevator lobbies on all floors and in elevator machine
room,shall recall elevators to designated primary recall level, or to
alternate floor if any primary floor devices are activated.
(2) Activation of a smoke detector in elevator machine room shall illuminate
fire hat indicator in each cab.
2. The operation of a sprinkler tamper, a duct smoked detector, deluge system trouble,
operation power failure, ground faults or open circuits shall automatically:
a) Display type of supervisory device received, location and device description on the
main FACP and remote annunciators LCD displays.
b) Sound the on board buzzer indicating a supervisory condition on both the main
FACP and remote annunciators LCD displays until acknowledged or event clears.
c) Flash the on board amber LED indicating a supervisory condition on both the main
FACP and remote annunciators LCD display until acknowledged or event clears.
Upon acknowledgement the amber LED shall stay lit solid until supervisory event
clears.
d) Send a supervisory signal to central station via the system dialer.
e) Record the event on the system log.
3. In the event of a low battery condition, open circuit in the system, a ground fault, or short
circuit, or any other system trouble shall cause the following:
a) Display type of trouble received, location and description on the main FACP and
remote annunciators LCD displays.
b) Sound the on board buzzer indicating a trouble condition on both the main FACP
and remote annunciators LCD displays until acknowledged or event clears.
c) Flash the on board amber LED indicating a trouble condition on both the main
FACP and remote annunciators LCD display until acknowledged or event clears.
Upon acknowledgement the amber LED shall stay lit solid until event causing the
trouble clears.
d) Send a trouble signal to central station via the system dialer.
e) Record the event on the system log.

be maintained for 2 hours without pressure loss. Pressure gauge shall be installed at the low
elevation point in the system.
c) Flow test each water flow device and associated alarm interconnection to ensure an
audible alarm is initiated within 5 minutes of flow initiation and continues until flow stops.
d) The main drain valves shall be opened and remain open until the system pressure
stabilizes. Static and residual pressures shall be recorded on the contractor's test certificate.
A written report shall be submitted detailing the results of all final testing including:
1. Copy of FACP printer output verifying proper operation of each device in alarm or
trouble, time stamped throughout the testing process.
2. Final System Acceptance in accordance with NFPA 72 and CSI Engineers project
requirements shall be formally documented utilizing a form similar to "Record of Completion" as
included in Figures 7.5 through 7.10 of NFPA 72.
Fire Alarm

2. Prior to formal Fire Department Test, the contractor shall conduct a preliminary test. The
electrical contractor and the equipment manufacturer shall completely test the system.
The manufacturer shall issue a letter of acceptability stating that all system components
