1.1.2 NETWORK SPRINKLERS

These are the technical conditions of the Project of the Network Sprinklers from the Offices of
the African Development Bank, on the 18th floor in Tower B Blocks 3 and 4 in Building Gika -
Luanda - Angola.

The supply of this network is secured from the existing network in place a pipe Dn100mm,
which localization is indicated on the drawings.
1.1.2.1 Pipes
Supply piping will be galvanized iron hot, following the layout indicated in the project and their
assembly shall perform the following requirements:
 When mounted sight clamps shall permit the free expansion, except when there are fixed
points;
 The clamps are isolated from the ducts by gaskets of suitable material, preventing the
transmission of noise to the walls of the building.
 The distances between clamps or other supports (which are suggested in project may
have an alternative proposal by the contractor, with the guarantee of not spoiling the
strength of the anchorages, ensuring that the normal position of the tubing is not changed
by the action of its own weight, vibrations, casual shocks, from the variations of
temperature or the firing of the sprinkler head), will be different as their diameters, but they
should never be greater than the following:
a) Horizontal tracks
Until Ø ½” mm …………………………………………………….1,00 m
From Ø ¾” mm until Ø 2” mm …………………………………..1,50 m
Above Ø 2” mm ………………………………………………….. 2,50 m
b) Vertical tracks
Until Ø 1” mm ……………………………………………………. 2,00 m
Above Ø 1” mm …………………………………………………. 3,00 m
DETAIL PROJECT 4
TECHNICAL SPECIFICATIONS
AFRICAN DEVELOPMENT BANK
In case there is coincidence of sprinkler heads with ventilation ducts, these are installed at the
underside of the pipes, fed by hangers derivatives of secondary branch lines.
Crossings in walls, ceilings or floors will be surrounded by metal arms of protection which must
allow the free expansion. At the crossing of different zones, piping should be sealed with mastic
fire - break or flameproof fire resistant sealing system "K6" the Bettor.
All piping is suitably protected from corrosion before fitted with two coats of primer particularly
suited to the nature of the protecting tube. The finish of the pipe will be done by painting with
two coats of oil identifying circuits as prescribed in the Portuguese Rule definitive No. 182/66 or
equivalent. The finishing of the tubes shall be performed only after the completion of the
leakage tests required the use of at least 12 Kg/cm2.
Knees are not accepted on this network.
Will be established the inclination of all secondary extensions in relation to the main one and
from all of them to the beginning.
All the ends of the branches end in T-shaped buffered, except those which are equipped with
purge air.
The main collector connection to the command post and of this to the main column will be
performed by flanges with gasket and screws.
On the ends of main extensions there will be a purge valve "CALLEFI" to allow purge air.
All piping shall be identified in accordance with the Portuguese Standard Definitive No.
182/1966 or equivalent.
1.1.2.2 Pendent sprinklers soaked
Be mounted in rows on tees tapped.
They will be type VIKING "spray", Pendent model, closed type, with a splash of red fuse to 68 º
C temperature firing and opening Ø ½.
1.1.2.3 Water flow switch
The flow rate indicator is intended to transmit an alarm to the central fire detection, whenever
there is a passage of water, whether by actuation of a sprinkler or by opening a valve test.

The flow indicator is connected to the Automatic System of Fire Alarm. It will be installed above
the main tube immediately before any connections of the installation.

1.1.2.4 Purge valve
This valve will be male type-spherical, with nickel plated brass body according to UNI 5705-65
or equivalent and chrome plated brass ball.
These valves should be double hydraulic tested:
 mechanical resistance - with the valve in the open position, a pressure corresponding to
the maximum working pressure plus 50%;
 Tightness - with the valve in the closed position, the most unfavorable conditions of
service (pressure and temperature of the fluid).
This valve will be installed downstream of the power supply allowing the purge flow for the
entire installation to ensure complete elimination of any extraneous solids through the valve
downstream of the feed.
1.1.2.5 Fire station
The spool type "NOHA" model 31SW or equivalent on steel plate painted RAL 9010
(1105x795x230 mm).
Must be fitted with a hose length of 25 m, 3 nozzle positions (closed, jet and fog) and isolating
valve at the entrance of Ø1 ".
The diameters of supplies are recommended in the Technical Rule No. 3 of the Insurance
Institute of Portugal or equivalent.
1.1.2..6 Generalities
All connections of pipes and equipments will be carried out according to the best rules of art
and tightness, fulfilling the stipulations of the General Regulations of Fire Safety in Buildings
(RG-SCIE).
If there are any omissions in the parts of this project should be met technical standards in force
as well as the decision of Owner and / or supervision of the work.
1.1.2..7 Annexures
To be installed according with the following architectural drawings.
- RIS 2.01 General Plan Block 4- Floor 18
