1.3 SYSTEM DESCRIPTION:

A. System: The system shall include a fixed supply of Halon 1301 in
storage containers, pressure switches, nozzles, piping, valves, control
panel, smoke detectors, and all other accessories necessary for a
complete system ready for operation. Appropriate equipment shall be UL
listed or FM approved for specific use on Halon 1301 systems unless
otherwise specified.

B. System Operation: System operation shall be based on a crosszoned,
priority matrixed, \"superzone\" or equivalent smoke detection concept.
An alarm condition on either smoke detection zone shall cause the alarm
horns to sound within the protected area with a steady tone and shall
close all doors normally held open. An alarm condition on the second
smoke detection zone shall cause the alarm horns to sound with a
pulsating tone rather than a steady tone, shall shut off all area
ventilation equipment and close all dampers, shall discharge Halon after
a preset time delay, shall signal the computers that a fire condition
exists, and shall actuate the building fire alarm system to sound a firm
alarm. The time delay shall be \[[ ]{.underline}\] seconds. Operation of
any manual release station shall cause the alarm horns to sound with a
pulsating tone, shall discharge the Halon, shall actuate the building
fire alarm system to sound a fire alarm, shall cause the area
ventilation equipment to shut off, shall close all doors normally held
open, shall signal the computers that a fire condition exists, and shall
close all dampers. Operation of any abort switch shall restart time
delay but shall not abort discharge of the Halon when the manual release
station is activated. Actuation of a manual release station or
underfloor or above ceiling smoke detector shall be indicated, by
device, on the remote lamp panel. A reset switch shall be provided in
the control panel which will restore the system to normal operating
condition after all alarm initiating devices are reset. Any manual
release station or smoke detector shall initiate the system operation,
as described above, during a single break or a single ground fault
condition on any alarm initiating circuit (Class A feature). The Halon
discharge circuit and alarm horn sounding circuit shall also operate
during a single break or a single ground fault condition on the
circuits. A silencing switch shall be provided on the control panel that
will silence the alarm horns but not affect the remote lamp panel
operation or reset the system. Underfloor and above floor areas shall be
flooded with Halon 1301 to provide a minimum 5 percent concentration at
70 degrees F. Maximum concentration shall not exceed 7 percent above the
raised floor and below the raised floor. The total discharge time shall
not exceed 10 seconds. Area openings shall be protected as required by
Section 2‑2.2 of NFPA 12A.

C. Electrical Supervision: The manual release stations, smoke detectors,
Halon discharge circuit, and alarm horn circuits shall be supervised to
indicate a break or ground fault condition, which shall be indicated, by
circuit, by a trouble signal on the control panel. A trouble signal also
shall occur when the alarm horn silence switch is not in the normal
position; with a pressure drop in Halon containers; or upon failure of
the normal AC power supply upon open battery connection, low battery
voltage, or operation of any other disconnect switch.

D. Air Handling System: The room air handling system must shut down upon
activation of the cross‑zoned detectors unless the air handling units
are only recirculating air within the room being protected. In addition,
dampers for ductwork in perimeter walls must be automatically closed
upon activation of the crosszoned detectors.

E. Time Delay: A time delay is required for evacuation of all personnel
from the protected space prior to discharge of the Halon. The following
formula should be used:

TD = ([ F ]{.underline}) + 15 seconds

3.5 feet/sec

where TD = time delay (seconds) and

F = distance from most remote point in the area being

protected to the closest exit door form the space

(feet).

Travel distance is measured on the floor starting one foot from the most
remote point, curving around furniture, storage and ending at the center
of the doorway.

[PART 3: EXECUTION]{.underline}

3.1 INSTALLATION:

A. General:

1\. Installation of Halon 1301 containers shall comply with Section
1‑9.5 of NFPA 12A.

2\. Halon 1301 containers shall be located as recommended in paragraph
1‑9.4 of NFPA 12A. Careful consideration must be given to the placement
of smoke detectors. This specification is based on cross‑zoned smoke
detectors activating the Halon 1301 discharge. Locations of detectors
shall be engineered for the specific area giving due consideration to
air currents and patterns and designed in accordance with NFPA 72E,
Automatic Fire Detectors. Detectors shall not be located within 3 feet
of supply air registers. Detectors shall be located on the ceiling and
under the raised floor area and above a suspended ceiling where the
space is used as an air plenum. Each separate space (underfloor, room
and above ceiling) shall be treated individually. The number of air
changes in each space will determine the number of detectors needed in
each space. Control panel and lamp panel should be within the computer
room near the main exit. Release stations and abort switches shall be
located next to all exit doors from the protected spaces. Sufficient
alarm horns shall be provided to be heard throughout the space above the
ambient noise level. If needed, remote trouble bell shall be located in
an adjacent corridor outside the protected space where the signal could
be heard by guard personnel, etc., during off‑duty hours. Cabinets for
wet‑cell batteries are generally hidden for aesthetic reasons.

3\. The total design should insure that no significant unclosed openings
remain around the perimeter of the protected area. Unclosable openings
can be protected as required by paragraph 2‑2.2 of NFPA 12A. This is
especially important near the floor since the Halon 1301 gas will
\"flow\" out any opening since it is heavier than air. Doors should be
provided with sweeps at the bottom and floor drains should be provided
with traps.

4\. The design may include provision for a means of ventilating the
space in the case of agent discharge. Normally, forced ventilation of a
space is usually achieved by use of open windows and doors and portable
fans. Each proposed installation should be evaluated separately to
determine whether any additional type of exhaust system is necessary.
However, this specification is for a Halon 1301 fire extinguishing
system only.

B. Manual Release: Stations shall be mounted with the operating handle
4‑1/2 feet above floor level.

C. Piping:

1\. Valves shall be installed to give sufficient room for expansion of
adjoining piping and for repair or removal without interfering with
another valve or pipe.

2\. Pipe and fittings shall be cleaned and all burrs removed from pipe
ends before assembly. The entire piping system shall be cleaned by
blowing air through before any nozzles or discharge devices are
installed.

3\. Piping through typical building walls, partitions, floor slabs, and
roof slabs, shall be run through sleeves of Schedule 40 pipe at least
two sizes larger than pipe being run and not smaller than 1 inch.
Sleeves through walls in finish spaces shall be flush. Sleeves shall be
packed with mineral wool or equal so as to be dust tight. \[Sleeves
through roof slabs shall extend above roof 6 to 10 inches and shall be
properly flashed.\]

4\. Conduit, beam, and \"C\" clamps shall not be used. Piping shall be
anchored to rigid members such as walls, floors, roofs, and columns to
prevent longitudinal or lateral sway. Hangers and supports shall be
installed as specified in Fed. Spec. WW‑H‑171E and NFPA 13. Pipe lines
shall not be used to support other pipe lines. Pipe supports shall be
installed to avoid interference with other piping, conduit, structures,
and equipment. Maximum spacing of supports shall be 10 feet.

5\. Color code pipelines and indicate flow direction in accordance with
Mil. Spec. 101B.

D. Control Panel: Halon system control panel and any remote panels shall
be located with base 4 feet above the finished floor.

E. Smoke Detectors: Shall be mounted on the ceiling, \[above the
ceiling\] and in the underfloor space in accordance with NFPA 72E. The
number and spacing of smoke detectors in each individual space (raised
floor, room and above ceiling) shall be determined by the number of air
changes for that space. Underfloor detectors shall be installed face
down near the top of the raised floor. Detectors shall not be located
within 3 feet of supply air registers. Adjacent detectors shall be on
alternate zones.

F. Evacuation Alarm Horns: Shall be mounted at least 8 feet above the
floor level unless limited by ceiling height or otherwise noted.

G. Wiring:

1\. System wiring for detector, alarm horns, Halon discharge, and manual
release station circuits shall be solid copper conductor not less than
No. 16 AWG size. Wiring for the Halon system power supply, battery power
supply and fan shutdown or door release shall be copper conductors of
not less than No. 12 AWG size. Conductors shall have an insulation rated
at least 75 degrees C. Wiring shall conform to NFPA 70, Article 760. All
conductors shall be identified by circuit. All conductors shall be
installed in metal conduit or tubing. Mounting boxes for exposed work
shall be iron or cast aluminum.

2\. All wiring shall be installed in a neat and workmanlike manner and
shall be trained parallel with or at right angles to panel sides and
backs. All circuit conductors entering or leaving each panel shall be
connected to terminal blocks with each terminal marked for
identification. All wiring within panels shall be readily accessible
without removing any component parts.

3.3 FIELD QUALITY CONTROL:

A. Testing: The Contractor shall conduct the performance and acceptance
tests of the system according to NFPA 12A. The Contractor shall furnish
necessary equipment, labor, and materials to conduct the testing.
Testing shall be conducted in the presence of the Contracting Officer
who shall be given 48 hours notice before any test is to be conducted.
All testing shall be coordinated with and approved by the Contracting
Officer. A letter certifying that the installation is completed and
fully operational shall be forwarded to the Contracting Officer. The
letter shall include the names and titles of the witnesses of the
preliminary tests. The Contractor and an authorized representative from
each supplier of equipment shall be in attendance to make necessary
adjustments related to the testing. Operation of all mechanical and
electrical equipment shall be made to ensure correct operation and
function. Use of temporary sealing methods shall be made to ensure
correct operation and function. Use of temporary sealing methods to
prevent the loss of any testing agent is not permitted. Each smoke
detector shall be activated by using actual products of combustion.
Installed pipe and fittings shall be pressure tested with nitrogen or
carbon dioxide prior to final connection of the containers. No Halon
1301 shall be discharged; however, the system shall be tested with a
discharge of Halon 122 substituted for Halon 1301. A recording meter
shall be furnished by the Contractor to record on tape the Halon
concentration. A minimum 5% concentration shall be maintained for 3
minutes and a minimum 3% concentration shall be maintained for 5 minutes
throughout the area. The 7% concentration shall not be exceeded for the
area above the raised floor or below the raised floor area. Sample
concentrations shall be recorded from three different locations, as
directed by the Contracting Officer, during the test. If the
concentrations are not within the limits or the system otherwise fails,
inservice tests shall be conducted again upon completion of repairs or
corrections. The Contractor shall furnish all Halon 122 for the tests.
