4.16 ELECTRIC
NOZZLE ACTUATOR
The electrical nozzle actuator is factory installed on the nozzle and requires only to be plugged into the mating monitor connector.
For nozzles with electric pattern control, a cable with a female, waterproof connector is provided at the outlet of the TFT RC Monitor
which attaches directly to several of TFT’s electric nozzles. The cable used is a dual-key, micro type plug assembly. Any other nozzle
should have the corresponding male electrical connector installed. Do not cut off the female connector on the monitor. This connector
is molded onto the cable and must remain in place to maintain the water tightness of the electrical system.
4.16.1 WIRING
The electric RC monitor is designed to control and is factory wired for a TFT electric actuated nozzle. Task Force Tips nozzles are
available with a male cord plug. After mounting the appropriate nozzle onto the monitor, plug the male cord from the nozzle into
the female cord located on the outlet of the monitor. Make sure the two coupling nuts are tightened securely to ensure a proper
watertight seal.
If retrofi tting an existing TFT nozzle, a male cord plug (TFT #Y5480) can be purchased and installed in place of the existing actuator
cord. Please consult factory for installation.
4.16.2 OPERATION OF FLUSH, FOG, STREAM
Nozzles without fl ush (All nozzles over 500 GPM)
TFT Remote Controlled (RC) nozzles are equipped with a capability exclusive to TFT
called “Smart Stream”. Small movements of the outer stream shaper are needed
to adjust fi ne fog while large movements are needed to see any change in straight
stream. TFT accomplishes this by using a variable speed motor and sensors to
tell the controls when the nozzle is in fog and when it is in straight stream. “Smart
Stream” automatically slows down the motor speed when the nozzle is operating
in fog patterns. Slow changes in nozzle reaction can help maintain the stability of
ladders and aerial platforms. On the back of every nozzle pattern actuator is a small
knob that rotates when the nozzle is changing pattern. This knob not only serves the
purpose of indicating motor rotation it also is used for manual override in the event
of power failure to the monitor. This small knob will change speed as the nozzle
moves thru its various patterns. This is NORMAL! Observing this speed change is
NOT an indication that the nozzle is binding or malfunctioning. If the end user desires
to have this function disabled please call the factory and the correct procedure for
accomplishing this change will be sent.

Nozzles with fl ush (Some nozzles below 500 GPM and all nozzles below 250 GPM)
TFT Remote Controlled (RC) nozzles are equipped with a capability exclusive to TFT called “Smart Stream”. Small movements of
the outer stream shaper are needed to adjust fi ne fog while large movements are needed to see any change in straight stream. TFT
accomplishes this by using a variable speed motor and sensors to tell the controls when the nozzle is in fog and when it is in straight
stream. “Smart Stream” automatically slows down the motor speed when the nozzle is operating in fog patterns. Slow changes in
nozzle reaction can help maintain the stability of ladders and aerial platforms. On the back of every nozzle pattern actuator is a small
knob that rotates when the nozzle is changing pattern. This knob not only serves the purpose of indicating motor rotation it also is
used for manual override in the event of power failure to the monitor. This small knob will change speed as the nozzle moves thru its
various patterns. This is NORMAL! Observing this speed change is NOT an indication that the nozzle is binding or malfunctioning.
Smart stream serves an additional function when used with nozzles that have fl ush capability built into the movement of the stream
shaper. When nozzles of this type are used on bumper turrets in pump and roll operations it is very important that the operator of the
unit not put the nozzle in fl ush accidently. A slight over travel past full fog on competitive monitor nozzles will cause the nozzle to enter
a partial or complete fl ush setting. When this occurs the fl ow of the nozzle can double or triple causing rapid exhaustion of the water
supply carried on board the vehicle. With “Smart Stream” technology the nozzle will automatically stop when it achieves the wide fog
setting and the motor will cease turning. If the operator desires to fl ush the nozzle he must release the button and then press it again
and the unit will travel into the fl ush position. Once understood this capability is extremely valuable for conserving tank water. If this
feature is not desired by the end user please contact TFT service for instructions on how to disable this feature.
