Use the Roll grooving equipment to groove the pipe. Check pipe
end, it must be smooth and free from indentation, projection and
roll marks in the area from pipe end to groove. Removed oil, grease
and dirt.
Measurement taken across grooved ends must not exceed the
maximum allowable diameter.
Align groove ends of matting components, before inserting the
gasket apply lubricant to gasket and housing interior. Insert one
bolt into the housing and thread the nut loosely on to the bolt
until the nut be flush with bolt end to allow for swing over
feature. Make sure housing key engage the groove properly on both
pipes.
Insert washer below the nut, remaining bolt and thread the nut
finger tight onto bolt. Nuts must be tightened evenly by
alternating sides according to torque.
Coupling installation shall be complete when visual
metal-to-metal contact is reached and the required torque is
achieved.
11.3.2.1 Setting Grooving Machine (reference from Victaulic
Operating and Maintenance Manual TM-VE270/271 VSD)
1. Make sure the proper roll set is installed on the tool for
the pipe size and material to be grooved. Rolls are marked with the
pipe size, part number and the color coded according to the pipe
material.
2. Loosen the wing nuts and move the adjustable guards to the
full up position. Tighten the wing nuts.
3. Set the groove diameter stop to the pipe size and schedule /
thickness to be grooved by backing off the depth adjuster lock and
aligning the depth adjuster with the proper.
4. If the tool is equipped with the optional pipe stabilizer:
Retract the pipe stabilizer, if necessary, to insert the pipe onto
the lower roll by loosening the locking handle and retracting the
stabilizer roler with the handwheel.
5. Insert a length of pipe that is the correct size and schedule
over the lower roll. Make sure the pipe end contacts the lower-roll
backstop flange. The pipe must rest directly on top of the roll and
must not be skewed to one side or the other.
6. Close the valve on the hydraulic hand pump by turning it
clockwise.
7. Pump the handle of the hydraulic hand pump to bring the upper
roll down into firm contact with pipe.
8. Loosen the wing nuts and adjust each guard to conform to and
tightly pinch the pad against the pipe. Tighten the wing nuts to
secure each guard in position. Remove the guard setting pad.
9. Loosen the wing nuts and adjust each guard to conform to and
lightly pinch the pad against the pipe. Tighten the wing nuts to
secure each guard in position. Remove the guard setting pad.
10. Remove the guard setting pad. Store the pad on the hook
provided under the hydraulic hand pump support.
11. Open the valve on the hydraulic hand pump by turning it
counterclockwise to allow the upper roll and arm to move the full
up position.
11.3.2.2 Pipes Grooving Procedure (reference from Victaulic
Operating and Maintenance Manual TM-VE270/271 VSD)
1. Before grooving the pipe, make sure the setting of groove
machine is being followed properly. Connect the tool to an
internally-grounded electrical source. When roll grooving pipe that
exceeds the maximum length, a roller type pipe stand must be used.
The roller stand must be capable of handling the weight of the
pipe, while allowing the pipe to rotate freely
2. Place the Pipe Stand at a distance slightly beyond half the
pipe length from the tool. Refer to the drawing.
Make sure the tool is level.
3. Position the pipe stand approximately 0-1/2 a degree to the
left for the tracking angle. Refer to the drawing. Note: when pipe
flare is excessive, right-to-left Trucking must be kept to a
minimum. It may be necessary to use less than a degree for the
tracking angle.
4. If the tool is properly set up in a level position, but the
back end of the pipe is higher than the end being grooved, the pipe
may not track, in addition, excessive flare may occur on the pipe
end. Refer to the Tool Setup section and the drawings above for
tool setup and pipe positioning requirements.5. Before grooving,
make sure all instructions in the previous sections of this manual
have been followed.
6. Connect the tool to an internally-grounded electrical
source.
7. Depress the safety foot switch momentarily to ensure the tool
is operational. The lower roll should be rotating clockwise when
viewed from the front of the tool. Remove foot from the switch.
8. Open the valve on the hydraulic hand pump turning it
counterclockwise to allow the upper roll and arm to move to the
full up position.
9. Insert a length of pipe that is the correct size and
thickness onto the lower roll. Make sure the pipe contacts the
lower-roll backstop flange completely. Remove hands from the
pipe.
10. Close the valve on the hydraulic hand pump by turning it
clockwise.
11. The operator should be positioned on the safety foot
switch/hydraulic hand pump side of the tool,as shown above. Pump
the handle of the hydraulic hand pump to bring the upper roll down
into firm contract with the pipe.
12. Depress and hold down the safety foot switch. The pipe will
begin to rotate clockwise when viewed from the front of the tool.
As the pipe rotates, begin forming the groove by pumping the handle
of the hydraulic hand pump slowly.
Do not pump the handle of the hydraulic hand pump too fast. The
rate should be sufficient to groove the pipe and maintain audible,
moderate-to-heavy load on the motor/drive.
13. Continue the grooving process until the depth adjuster lock
comes into contact with the top of the tool body. Continue pipe
rotation for several revolutions to ensure groove completion.
14. Release the safety foot switch, and withdraw foot from the
switch.
15. Open the valve on the hydraulic hand pump by turning It
counterclockwise to release the pipe. Remove the Pipe from the
tool.
16. If no more roll grooving will be performed for a
while,disconnect the tool from the electrical source.
The groove diameter must be within specification for the
diameter and wall thickness of pipe. The groove diameter should be
checked and adjusted, as necessary, to ensure grooves remain within
specification.
11.3.2.3 Pipes Threading Procedure
1. A die head will be attached to cut the thread.
2. Machine now have the ability to threads pipes.
3. A heavy duty pipe threader can also cut your pipe into
workable sections.
4. The pipe threading machine will be used to thread the end
section of your pipe.
5. Inspect the pipe threader before beginning and replace dies
or any parts that show signs of wear.
6. Mount your pipe firmly in the pipe vise by placing it in the
vise and then tightening until it is held tightly.7. Cut the end of
the pipe cleanly and squarely by using a pipe cutter. The pipe
cutter will have a thin cutter wheel, which will slice through pipe
as you guide it in the space. Be sure to wear goggles and
protective gear.
8. Ream the cut end of the pipe to remove any burrs from the cut
using a reamer, which is a cylinder shaped rotary cutting tool that
you run smoothly across the freshly cut edges of the pipe to remove
rough edges.
9. Select your die head according to the size and type of pipe
you are threading and the thread from your require.
10. Place the die head over the pipe on the threader.
11. Press steadily on the front of the die head, while
simultaneously pushing the handle down to start threader. Before
placing too much pressure on the handle, check to be sure that the
ratchet pawl is engaged.
12. Use weight as leverage to apply pressure on the handle,
while holding it firmly. Be sure to maintain proper footing and
balance for maximum control. Never use a tool or mechanism to hold
the handle in place in order to free your hands, this can be
dangerous and could result in injury.
13. Apply threading oil generously while threading. Using on oil
too thin as a substitute for threading oil can result in
sub-standard threading.
14. Cease threading when the end of the threading die is flat
against the end of the pipe. When the die is even with the pipe,
that means the correct threading size has been reached. If you
continue pushing after this point, you will damage the thread.
15. Reverse the ratchet mechanism and turn the die head in the
opposite direction. Be care full to maintain control of the
threader as the dies are removed. Threads can be damaged when the
die head is being removed if you dont maintain control and move the
piece smoothly.
16. Stand the pipe on end and gently tap it to remove any
particles that may be lodges within.
17. Clean the pipe with cloth, removing any oil. Be careful, the
threads will be very sharp.
18. Seal the threading with a pipe thread compound when
attaching the pipe to the connector.
19. Clean the pipe threader machine thoroughly after use so the
oils and metal pieces do not damage the machine, which could cause
sub-standard threading during your next project.

Tighten Nuts: tighten the nuts evenly by alternating sides until
metal-to-metal contact occurs at the angle bolt pads. Make sure the
housingss keys completely engage the grooves and the offsets are
equal at the bolt pads. To ensure a rigid joint, equal and positive
offsets are preferred. Note: It is important to tighten the nuts
evenly to prevent gasket pinching. An impact wrench or standard
socket wrench or standard socket wrench can be used to bring the
bolt pads into metal-to-metal contact. Refer to the impact wrench
usage Guidelines section in this manual.
Visually inspect the bolt pads at each joint to ensure
metal-to-metal contact is achieved.
Negative bolt pad offsets can occur when the nuts are not
tightened evenly, which produces over-tightening of one side and
under-tightening of the other side. In addition, negative offsets
can occur if both nuts are under-tightened.
11.4.6 Mechanical Tee Installation Procedure(ref. Victaulic
field installation handbook)
3a.Make sure the locating collar engages the outer hole
properly. Check this engagement by rocking the upper outlet housing
in the hole.

container. Provide water supply. Provide flow measurement in
flushing water supply line to be used as basis for verification of
flow velocities in piping system. Test drain valve shall be flushed
in fully open position at drain points. The drain points should be
tapp or near the floor drain. If ever there is no floor drain near
the drain point, we can used empty drum or container to stored
flush water. Observe proper disposition of flush water. All piping
systems shall be flushed using high pressurized pump.
Flushing has to be done by filling the system from one and
leaving the bottom valve open at the opposite end with pressurized
clean potable water with required flow maintaining 10 ft/sec water
velocity to carry out all debris/dirt/slag along with it. The
flushing operation shall be continued until satisfactory cleaning
is ensured then close all bottom ends. Note: Disinfections process
in fire fighting is not NFPA requirement, the disinfections
chemical material will cause rusting and reactions with steel
pipes. Refer to RFI Submission Reference: 421-A000-M-AV-01712
Rev.00. And if ever required by consultant the disinfections will
be prepared by specialist and will be separately
submitted.11.4.11.4 Interface The wet pipe system employs automatic
(fusible link, glass bulb, or closed type) sprinklers attached to
piping containing water pressure at all times. When fire occurs,
individual sprinklers are actuated by the heat, and water flows
immediately.S.N.FCFCTemperature ClassificationColor CodeGlass

Alarm Check Valve the wet pipe system is controlled by an alarm
check valve. When a sprinkler activates, the flow of water raises
the alarm valve clapper from its seat, thereby lifting the pilot
valve disc from the nozzle. These permits water to enter the alarm
line. A water motor gong is actuated by the flow. An optional
pressure switch may be attached on the alarm line to provide an
electric signal. The electric can be send to the buildings main
fire alarm control panel.
Where the water supply has constant pressure, the alarm valve is
used without the retard chamber. In cases where a local alarm is
adequate, water is admitted directly to water motor-driven gong. If
no water motor gong is required.

FACTOR CONSIDERATON
MOUNTING SURFACEContainer brackets must be mounted securely to
solid load-bearing surfaces that willsupport the container
load.
Some installations may require additional mounting support not
supplied by supplier
ENVIRONMENTAL EFFECTSContainer(s) should be located in clean,
dry, and relatively vibration-free areas. Avoidaisle ways and other
high traffic areas where physical damage or tampering is more
likely.Container(s) should never be mounted where the container
could potentially be splashed with, or submerg ed in any liquid.Do
not locate containers where they would be subject to physical
damage, exposure to corrosive chemicals, or harsh weather
conditions.
TEMPERATURE RANGEContainer locations must be between 32oF (0 Deg
C) to 130oF (54.4 Deg C)Temperatures outside of this range may
result in the system not supplying the desired quantity of agent or
accide ntal discharge.
SERVICEABILITYIn general, the larger the container, the more
difficult it will be to remove it from thesystem for maintenance
and service.
However, smaller containers that are located in a sub -floor
space, under a computer bank,or above the ceiling over the same
computer bank can be difficult as well.
FLOOR SPACEConsideration should be gi ven to the space available
to install the container(s).
11.4.12.5 Nozzle Installation
Always verify the nozzle identification number (stamped on the
closed end of the nozzle) matches the nozzle part number listed on
the system installation plans. All nozzle locations should be
within 1'- 0" (0.3m) of their intended locations on the system
plans. Discharge Nozzles must be mounted in the vertical position
and can face either up or down. The piping should be blown clear to
remove chips, mill scale, or metal shavings before the nozzles are
installed. 360 Nozzles should be located in a symmetrical, or near
symmetrical, pattern within the protected area. Nozzle patterns
need to overlap, to adequately cover the area without any blind
spots due to nozzle locations. Apply to all Nozzle types.
180 Nozzles should be located in a symmetrical, or near
symmetrical, pattern within the protected area. 180o Nozzles should
be located along the perimeter of the area discharging along the
perimeter and toward the opposite side. These nozzles can be
located a maximum of 1-0 (0.3 m) out from the wall.
11.4.12.6 Conduits and Cable Installation
Ensure all the conduits and wiring installed in FM200 system are
according to the project specification and approved drawing or
conduits are bent by a bending machine. Field wiring (16WG) cables
may be installed to an EMP conduit either manually or with the
assistance of the pulling mechanism. Route all field wiring through
the appropriate conduit knockouts. Provide adequate wire length for
stain relief. After the pulling the wire into the control panel
enclosure, verify wire for ground-fault absence and acceptable
impedances prior to connecting the initiating and indicating
circuits.
11.4.12.7 FM200 Panel Installation
The mounting location of the control panel enclosure is very
important. Vibration, dust, moisture, electromagnetic interference,
and radio frequency interference are all types of problems that
could adversely affect the successful operation of the equipment.
Choose a mounting location that is free from environmental
problems. The control panel should be installed so that viewing
window is approximately 60 above the floor. Do not install in an
environment that exceeds the temperature ranges. Ensure the FM200
panel and alarm devices are installed according to the system
layout in that room. Test the key to make sure all the key
functions are working properly.
11.4.12.8 Pneumatic Test Procedures
Pneumatic pressure test has to be conducted on FM200 pipe work
as per NFPA 2001 Chapter 7 Inspection, Testing, Maintenance and
Training.
7.7.2.2.12 - The piping shall be pneumatically tested in a
closed circuit for a period of 10 minutes at 40 psi (276 kpa). At
the end of 10 minutes, the pressure drop shall not exceed 20
percent of the test pressure.
It is always preferable (and the right practice) to test the
pressure for each system or network.
Plug all nozzle openings.
Make sure the tightness of main joints physically.
Leave two ends of the network open.
An approved pressure gauge is to be used which has got a reading
to 100 psi.
Connect pressure gauge to the lower end of the network.
Connect an isolation valve (ball type) to the other end.
Pneumatic pressure can be obtained by Air Compressor Air
Supply.
Connect either the compressor to the other end.
Pressurize the pipe work.
Check the pressure gauge reading.
Once the pressure gauge reaches 40 psi, close the isolation
valve.
Note the time.
After 10 minutes, check the pressure gauge.
If the pressure gauge remains intact, the test is PASSED.
Visual leakage or pressure drop less than 32 psi indicate a
failure of test. In this case, check the joints of the network and
tighten the lose joints and conduct the test again.
11.4.12.9 Integration of FM200 Systems
FM200 Fire Suppression Systems, when installed to protect
electrical/electronic hazards or high value assets, will be fully
effective if and only if the system is integrated with other
essential services in the building like HVAC System, Main Fire
Alarm Systems, BMS Systems, Emergency Power Shut Off for vital
electrical equipments, etc.,.
Also, the room has to be completely sealed so that FM200
discharged will not escape. Escaping any amount of FM200 agent will
result a lower concentration which would be considerable especially
FM200 concentration for the room is a minimum as 7% volume by
volume.
7.7.2.3* Review of Enclosure Integrity all total flooding
systems shall have the enclosure examined and tested to locate and
effectively seal any significant air leaks that could result in a
failure of the enclosure to hold the specific agent concentration
level for the specified holding period. Quantitative results shall
be obtained and recorded to indicate that the specified agent
concentration for the specified duration of protection is in
compliance with Section 5.6, using an approved blower fan unit or
other means as approved by the authority having jurisdiction. HVAC
Systems should be turned off prior to the gas discharge and also
any openings related with HVAC Systems are to be closed to assure a
complete sealing of the room. Any openings of the duct to the room
in fresh air or return ducts are to be closed completely by a
motorized fire damper. Most of the motorized fire dampers are of
spring return actuator type (fail safe). The actuator of the damper
will get a signal from the pre-discharge (2nd Stage) relay and then
will close the damper to ensure the total sealing of the room.
Wall mounted Motorized Damper for opening of duct on wall -
examined and tested to locate and then effectively seal any
significant air leaks that could result in a failure of the
enclosure to hold the specified agent concentration level for the
specified holding period. Quantitative results shall be obtained
and recorded to indicate that the specified agent concentration for
the specified duration of protection is in compliance with Section
5.6, using an approved blower fan unit or other means as approved
by the authority having jurisdiction. Motorized Fire Damper is to
be provided on the duct opening to close the damper prior to the
system discharge. Actuator will be connected with FM200 Control
Panel to get the actuation relay contact (pre-discharge state).
Pre-discharge relay will be connected to the damper (if it is a
failsafe or spring return actuator) to close prior to discharge.
Damper can be reset after the hold time after discharge and after
the FM200 system is reset.
Multi-opening of HVAC Duct for multiple openings, it would be
better duct just outside the room or inside the room so that the
multiple dampers can be avoided. For that purpose, In-Line
Motorized Fire Damper can be utilized.
If, for any reason, the in-line damper can be installed only far
from the room, then the volume of the ducting till the damper will
have to be added to the room volume for calculation of FM200
agent.
Pre-Discharge Relay will be connected to the Damper (if it is a
failsafe or spring return actuator) to close prior to discharge.
Damper can be reset after the hold time after discharge and after
the FM200 system is reset.
Sealing the Hazard Enclosure as per NFPA 2001, the room or the
hazard to be protected by FM200 system should be properly sealed in
order to hold the FM200 agent discharged into the room for the
specific hold time. This document analyzes different scenarios of
sealing the hazard.
Sealing Void: (Rooms with false ceiling) unless specified,
ceiling void normally contains lighting circuits and HVAC ducts.
They dont need to be protected by FM200 generally. Ceiling void can
be sealed properly and isolated from the room protected by FM200.
For that purpose, false ceiling should be made of fire rated air
tight materials. Ceiling tiles (perforated or non-perforated)
cannot be considered to fall in this category. When the ceiling
void cannot be isolated comply from the room, theceiling void
should be protected bey FM200 system. But, in this case, it is to
be made sure that the walls are to be extended to the ceiling slab
so that the complete isolation of the room with ceiling void is
obtained from other rooms.
Raised Floor are normally installed in the control rooms,
computer rooms, server rooms, UPS rooms, Data rooms, Telephone
rooms, etc., for running the data cables. In this case, floor voids
are considered as electronic hazards and are to be protected by
FM200 systems.
Doors normally, it is found that the doors will have a gap and
this would result the scape of FM200 agent through the gap. Such
gaps are to be closed by approved fire sealant. Sealants can be
provided either with door or with the frame. Sealants will be
flexible and ensure a complete tightness when the door is
closed.
Door with Louvers there are certain doors with louvers existing.
In this case, Motorized Fire Dampers or Fire Shutters will have to
be provided on the louvers to close the opening prior to FM200
discharge. Motorized Fire Damper is to be provided on the louver
opening to close the damper prior to the system discharge. Actuator
will be connected with FM200 Control panel to get the actuation
relay contacts (pre-discharge state). Pre-Discharge Relay will be
connected to the damper (if it is a failsafe or spring return
actuator) to close prior to discharge. Damper can be reset after
the hold time after discharge and after the FM200 system is
reset.
Cable Trenches cable trenches are to be protected by FM200
system if they are not able to isolate from the room. The isolation
should be by means of air tight cover plates, sealant foams in a
cable entries and fire sealants in any other gaps of the cover
plates.
11.4.12.10 Interface
FM200 systems will have to be monitored by the Main Fire Alarm
Systems for Alarm, Gas release and Trouble, unless specified
otherwise.
FM200 Systems are preferred to be monitored by the BMS systems
as well for Alarm and Trouble unless specified otherwise.
Smoke detection within the hazard area shall be provided by grid
of alternating photoelectric smoke detectors. Activation of any
detector in the grid shall activate the Grid Detector functions
described below. Activation of a detector other than of the grid,
shall start the Confirmation sequence below.
All automatic extinguishing agent release shall be through
dedicated extinguishing (FSCP) control panels listed for the
purpose and not directly by FAS. However, FAS shall monitor the
extinguishing system for alarm and trouble.
Upon operation of the Grid Detector associated with the
protected area, the system shall:
Activate a positive fire alarm sequence. Release fire / smoke
dampers. Shutdown HVAC System supplying protected area.
Upon confirmation of the Alarm by a second detector (not part of
the grid), the system shall:
Activate fire alarm system Stage 2.
Upon activation of the manual release station the system
shall:
Activate fire alarm system Stage 2. Release fire / smoke
dampers. Shutdown HVAC System supplying protected area.

Assembly
Cylinder Racking Assemblies are designed to support ProInert
cylinder on multiple or main/reserve cylinder applications.
Cylinder Racking Assemblies are available in single, double or
triple row configurations. All necessary hardware and support
material are supplied with each assembly.
Double and Triple Row Rack Assemblies utilise Unistrut as both
the front and back supports together with Clamp Rod Assemblies to
secure the cylinders to any structurally solid surface.
11.4.13.5 Cylinder Assembly
The following sections provide procedures for the correct
installation and mounting positions of Fike Proinert Cylinder.
Cylinders should be located in clean, dry and relatively
vibration-free areas. Avoid aisles and other traffic areas where
physical damage or tampering is more likely. Cylinders should never
be mounted where the cylinder could potentially be splashed with,
or submerged in any liquid. Cylinder storage location must be
within a temperature of - 4F to + 120F (-20C to +48.9C) for system
components to function properly. Cylinder brackets must me mounted
securely to solid load-bearing surfaces that will support the
cylinder load. Some installations may require additional mounting
support not supplied by Fike.
Cylinders should be located to allow easy accessibility to the
actuation package for manual release of the system. Manual release
is achieved by removing the locking pin and pressing the red manual
activation strike knob adjacent to the electric solenoid. This will
pneumatically initiate the discharge sequence.
Warning: The ProInert valve Pneumatic Actuator should always be
the last component installed on any Fike ProInert system.
Procedure:
1. Confirm the cylinder location and mount the cylinder rack and
manifold support.2. Position the cylinders in the racking. Do not
remove the safety/shipping cap until the cylinder are fully
mounted. The orientation of the valve outlet is indicated by a
label on the cylinder neck. Generally discharge outlets will be to
the right and at an angle of 30 degree to the wall.3. Secure the
cylinders and mount the manifold.4. Fit the discharge hose
assemblies to the manifold.5. Install and test the discharge pipe
network.6. Remove the safety/shipping caps and valve outlet caps
