1.0 MEANING OF SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved
with a particular hazard. Per ANSI standard Z535.4-1998 the definitions of the three signal words are as follows:
|
DANGER indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury. |
 |
WARNING indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury. |
 |
CAUTION indicates a potentially hazardous situation which, if not avoided, may
result in minor or moderate injury. |
2.0 GENERAL INFORMATION
|
This equipment is intended for use by trained personnel for
firefighting. Its use for other purposes may involve hazards not addressed by
this manual. Seek appropriate guidance and training to reduce risk of injury. |
| The Task Force Tips Protector is a simple and
rugged fixed station monitor with many unique features. • Its unique (patent
pending) waterway has low friction loss and delivers water to the nozzle with
fewer twists and turns than a conventional monitor. • The optional built-in
on/off valve with position indicator eliminates the the additional costly valve.
• The Protector can be directly bolted to many common pipe flanges. • The outlet
is available with various 2.5 inch male threads or with an integral fixed
orifice fog nozzle with adjustable pattern control. • The integral nozzle is
available in several flows. • A long stream straightening vane in the discharge
section reduces turbulence. • The design requires no regular grease application.
• Swiveling elements and seals (including valve seat) can be replaced in a few
minutes with just one tool. • Threaded ports (1/4" NPT) are provided for drain
valve and pressure gauge installation. • The Protector is available in UNC
C83600 brass, with a baked-on powder coat finish, as well as powder coated
hardcoat anodized ANSI 356.0-T6 aluminum. • The swivel clamps, 3 inch valve
ball, trunnions and hardware are 18-8 stainless steel. • The monitor may be used
to deliver water or foam streams. |
2.1 STYLES AND OPTIONS
The Protector station monitor comes in four basic styles
as shown in the figures below:
2.2 PART IDENTIFICATION
Figure 1.2 shows a Protector monitor with "Valve and
Threaded Exit" and identifies the various parts and controls.
2.3 OVERALL DIMENSIONS
3.0 INSTALLATION
3.1 FLANGE SIZES
The table below gives the available flange designations
and actual sizes. The designation is cast into the flange surface.
3.2 GENERAL MOUNTING
The Protector station monitor is installed to a riser
pipe by a bolted flange joint. Check that no interference exists between
the Protector and surrounding hardware that would limit its usefulness.
If a valve is to be mounted under the Protector, check that no
interference exists with the valve handle. If a butterfly valve is to be
mounted under the Protector, check that no interference exists between
the butterfly and the flanged base of the Protector when the valve is in
its open position.
3.3 BOLTED FLANGE JOINT
The use of flat faced flanges (without raised face) and
full face gasket is recommended. Bolts should meet the requirements of
high strength or intermediate strength bolting as defined in ASME
B16.5-1996 sections 5.3.1 and 5.3.2. The flanged connection and gasket
must withstand the internal pressure as well as shear and bending due to
the nozzle reaction. Use a full face gasket per ASME 16.21-1992 or ISO
7483. Nozzle reaction can be as high as 950 lbs (1250 gpm at 225 psi)
which would give a 1200 ft-lb bending moment at the flange joint (950
lbs times 1.25 ft). The tightening sequence of the bolts is shown in
figure 2.3.
Injury can occur from an inadequately supported monitor. The mounting
must be capable of supporting the nozzle reaction force which can be as
high as 950 lbs. This monitor is not intended for portable use. Flanges
and pipe made from plastic are inadequate for monitor mounting and must
not be used.
|
3.4 WATER SUPPLY
The Protector (or any monitor) must have an adequate
supply of water and pressure to be effective. Make sure that pump(s) and
water supply are sufficient and reliable. See section 3.0 for Protector
pressure loss. Use with salt water or brackish water will shorten the
service life of any product due to corrosion. |
|
An inadequate supply of pressure and/or
flow will cause an ineffective stream and can result in injury, death or
loss of property. |
3.5 NOZZLE FOR THREADED EXIT
The Protector is available with 2.5 inch male threads
(NH, BSP, or NPSH) for attachment of a nozzle. Greasing of threads
before screwing on nozzle will reduce the chance of corrosion. |
|
Nozzle threads must match threads on the
protector. Mismatched or damaged threads may cause nozzle to leak or
uncouple under pressure and could cause injury. |
|
Do not couple aluminum to brass.
Dissimilar metals coupled together can cause galvanic
corrosion that can result in inability to unscrew the threads or
complete loss of thread
engagement. |
| |
|
3.6 PORT FOR DRAIN VALVE
The Protector has a ¼" female NPT threaded port for installation of a
drain valve. This port is located just above the lower swivel and is
shipped from the factory with a pipe plug installed. A drain valve is
required in environments, which will reach temperatures below freezing
to eliminate the risk of ice forming in the Bell Casting. The Protector
may become damaged if ice is allowed to form in the Bell Casting.
3.7 PORT FOR PRESSURE GAUGE
The Protector has a ¼" female NPT threaded port for installation of a
pressure gauge if desired. This port is located by the upper swivel and
is shipped from the factory with a pipe plug installed. If a pressure
gauge is installed, check that no interference exists between the gauge
and the upper swivel locking knob.4.0 PRESSURE LOSS
Figure 4.0 gives a graph of pressure loss
through the Protector station monitor.
4.1 VALVE OPERATION
In models equipped with a built-in valve, the flow is OFF when the valve
handle is horizontal and ON when the handle is vertical. Parts are
manufactured so that the valve cannot be assembled out of phase. A
position indicator shows the valves position as "OFF" or "ON". The
position that the valve is normally left in will depend upon your
particular location's standard operating procedure. Operate the valve
slowly to reduce water hammer.
4.2 SIDE TO SIDE ROTATION AND ROTATION LOCK
The side to side direction (rotation) of the stream is changed by
pushing or pulling horizontally on the direction control handle (see
figure 4.2). If the Protector is equipped with a built-in valve and the
valve is in the OFF position (handle horizontal), the valve handle may
be used to change the azimuth of the monitor. Twisting the rotation
locking knob clockwise will increase the drag on the lower swivel joint
to "lock" the monitor in a particular direction.
4.3 ELEVATION CONTROL AND ROTATION LOCK
The up and down direction (elevation) of the stream is changed by
pushing or pulling vertically on the direction control handle (see
figure 4.2). Twisting the elevation locking knob clockwise will increase
the drag on the upper swivel joint to "lock" the monitor at a particular
elevation. Select discharge devices that do not exceed the 70 ft-lb
locking capability of the elevation lock. |
|
Master stream flows are very powerful and
capable of causing injury and property damage. Make sure the monitor is
pointing in a safe direction before water to the monitor is turned on.
Use care in directing the stream. |
|
Care must be taken when loosening
elevation locking knob so nozzle does not swing down
quickly. Keep one hand on direction control handle while loosening
elevation control knob. Be prepared to exert force on direction control
handle as knob is loosened. |
|
When pressure is released, nozzle will
swing down if locking knob is not adequately tightened. |

5.0 PROTECTOR WITH BUILT-IN NOZZLE
5.1 BUILT-IN NOZZLE FLOW CHARACTERISTICS
The Protector is available with a built-in nozzle.
This built-in nozzle is a fixed orifice fog nozzle. Available flows are
350, 500 and 750 GPM at 100 PSI. Flow characteristics are shown in
figure 5.1. The pressures shown are at the base of the nozzle. Figure
5.2 gives the stream trajectory of each flow at 30 degrees elevation
above horizontal and still air conditions.
 |
5.0 BUILT-IN NOZZLE FLOW
CHARACTERISTICS
Approximate effective stream trajectory at 30 degree
elevation in no wind condition. Distance to last water drop
approximately 10% farther. Range of foam solution is approximately 10%
less than results expected with water.
(Tail or head winds of 20 mph may increase or decrease the range
approximately 30%)5.2 PATTERN CONTROL
The Protector's built-in nozzle has full
pattern control from straight stream to wide fog. Turning the stream
shaper clockwise (as seen from the operating position behind the nozzle
-see figure 5.2) moves the shaper to the straight stream position.
Turning the shaper counterclockwise will result in an increasingly wider
pattern. Since the stream trim point varies with flow, the stream should
be "trimmed" after establishing a steady flow. To properly trim the
stream, first open to a narrow fog. Then close the stream to parallel to
give maximum reach. NOTE: Turning the shaper
further forward will cause stream crossover and reduce the reach of the
stream.
5.3 FLUSHING OF DEBRIS
Small debris in the water may get caught inside the nozzle. This trapped
material will cause poor stream quality, shortened reach and reduced
flow. To remove debris trapped in the nozzle refer to figure 5.3 and:
• Shut off flow to the nozzle.
• Unscrew baffle from the nozzle using 1-1/8 inch (28mm) socket.
• Remove debris. Flow water to flush if necessary.
• Reinstall baffle. Tighten to approximately 30 ft-lbs (40
Newton-Meters).
Larger debris can get caught in the exit section at the turning vane. If
this occurs the exit section must be removed to clear the blockage. See
section 6.1 to remove exit section.
 |
6.0 MAINTENANCE AND REPAIRS
The Protector Station monitor requires no routine maintenance. All seals
slide on plastic surfaces and require no .
The swiveling joints use plastic sliding elements that also do not
require grease. The Protector should be inspected annually and after
each use.
In particular, check that:
• There are no leaks with valve off and while flowing.
• Valve handle moves freely between open and closed positions.
• Valve handle position indicator is functioning properly ('OFF' when
horizontal, 'ON' when vertical).
• Swivels rotate while flowing at expected pressure and flow.
• Locking knobs loosen and tighten sufficiently.
• Nozzle is free of debris.
6.1 SWIVEL INSERTS
If the force to swivel becomes excessive, it may be due to damage to the
plastic swivel inserts. The inserts are replaced as follows:
• Turn off water.
• Remove the cotter pin and then the nut on the locking knob with a 1/2
inch (13 mm) socket.
• Remove the locking knob.
• Separate the joint by pivoting the clamp piece off of the flanged
section.
• Pry out the swivel inserts.
• Clean away any dirt on flanges and clamps.
• Install new swivel inserts into clamp pieces.
• Reassemble joint. Important: Do not allow any dirt or grit on flanges
and swivel inserts.
6.2 LOWER SWIVEL SEAL AND VALVE SEAT
If the lower swivel joint leaks externally, or the valve does not fully
shut off, then the lower swivel seal and/or valve seat may need to be
replaced. To replace these parts:
• Separate the swivel joint by following the sequence in section 6.1.
• Pull out the valve seat and lower swivel seal.
• Inspect parts and replace with new parts as needed.
• Apply grease to surface of seal.
• Snap black seal in groove on white valve seat.
• Insert assembly into monitor white end first.
6.3 UPPER SWIVEL SEAL
If the upper swivel leaks, then the upper swivel seal may need to be
replaced. To replace the upper swivel seal:
• Separate the swivel joint by following the sequence in section 6.1.
• Inspect the seal and sealing surfaces.
• Apply grease to surface of seal.
• Replace damaged parts as needed.
