PATTERN SELECTION
1. Disconnect WHITE wire from any connections if applicable.
2. Turn PREDATOR II ON.
3. Momentarily touching and removing the WHITE wire(s) to ground
 
will advance the PREDATOR II to the next flash pattern. Touching and
removing the White wire for more than a few seconds will allow you to change the
PREDATOR II to the previous pattern. See flash pattern table. Continuing to touch 
and remove the WHITE wire(s) to ground will allow you to scroll through the pattern 
list. After pattern #33 is reached the list will start over again at pattern #1.
NOTE: The PREDATOR II is equipped with flash pattern memory. Once you have
selected a pattern the PREDATOR II will always activate to that pattern every time 
the unit is turned on. Tape up and secure WHITE wire so that it will not accidentally 
change your selected pattern.
PATTERN RESET
 
1. Remove Power.
 2. Place WHITE (sync) wire to ground.
 3. With sync wire grounded, re-power RED wire.
 4. Maintain for one second (light will dim).
 5. Remove power and ground (pattern 1 set). 
SLAVE MODE
The PREDATOR II is capable of being activated through the use of a user supplied
flasher by putting it in slave mode.
1. Permanently connect the PREDATOR II WHITE and BLACK wire to a good,
convenient ground.
2. Connect the PREDATOR II RED wire, through a 5Amp fuse, to the output of a
+10-30Vdc switching flasher.
NOTE: The PREDATOR II is a factory sealed unit that CANNOT be serviced in the
field. Any attempt to gain access to the PREDATOR II unit will most likely cause 
permanent damage and void its warranty.
MOUNTING INSTRUCTIONS
Important: DO NOT over tighten mounting 
screws or nuts. This could cause permanent 
damage to the bracket. Use appropriate 
hardware for mounting.
1. Locate flat mounting location for PREDATOR II 
Surface Mount LEDs.
2. Using the gasket as a template, mark and drill
pilot holes for mounting screws.
Note: The mounting holes will be
slightly greater than 4-1/8" center to center. 
These dimensions are for approximate 
reference only.
3. Drill 1/2" hole at the center of the mounting
hole pattern (see layout - do not scale).
Note: If possible, the back side of this
hole should be deburred where drill 
breakthrough occurs.
4. Route cable through hole in gasket and make
electrical connections (Red-power, 
Black-ground. White is for ID and pattern 
selection and will be taped after selection is 
made). If the final location of the cable will be 
inaccessible, ID and pattern selection must be 
made before final installation. 
5. Install gasket over rear of light and loosely
install unit with #8 self-threading screws and 
plastic washers. Washer must be installed 
under the head of the screw. Note: Gasket 
must be used to prevent oxidation and 
galvanization of the mounting surface if 
differing metals come in contact. 
6. When final position of unit is obtained tighten
screws. DO NOT OVER-TIGHTEN!
IMPORTANT: DO NOT connect this
device to a strobe power supply.
