CAUTION! DO NOT LOOK DIRECTLY AT THESE LEDS WHILE THEY ARE ON.
MOMENTARY BLINDNESS AND/OR EYE DAMAGE COULD RESULT!
IMPORTANT WARNING!
Installation and Wiring:
External Flasher Models: This product draws significantly less current
than a standard incandescent automotive bulb. If your flasher does not
operate properly, it may be necessary to replace your flasher module
with a Whelen® flasher module. Contact your sales representative for
application.
Caution: Permanent mounting of this product will require
drilling. It is absolutely necessary to make sure that no other
vehicle components could be damaged by this process. Check
both sides of the mounting surface before starting. If damage is
likely, select a different location.
WARNING! All customer supplied wires that connect to the
positive terminal of the battery must be sized to supply at least
125% of the maximum operating current and FUSED at the battery
to carry that load. DO NOT USE CIRCUIT BREAKERS WITH THIS
PRODUCT!
NOTE: The color of the Positive Wire is determined by the color of
the LED. In this manual, RED is used as a reference color.
1.
Using the dimensions shown, mark the 2 mounting hole locations
and wire access hole location onto the mounting surface.
2.
Drill the two, 0.250” diameter mounting holes and a 0.625”
(minimum) wire access hole into the mounting surface.
3.
Place the gasket into position on the rear of the M6 assembly
(see Gasket Note). Insert the slotted hole screw grommet through
the mounting holes on the M6/Gasket assembly.
4.
Feed the M6 wires through the wire access hole in the mounting
surface. Press the M6/Gasket/Grommet assembly onto its
mounting location so that it is flat against the mounting surface.
5.
With the assembly in position and using the hardware provided,
tighten the mounting screws until the lighthead assembly is
drawn firmly against the mounting surface. A torque value of 12
in-lb. (max.) is typically required to achieve this. DO NOT OVER
TIGHTEN!
6.
Using appropriately sized wires (minimum 18 AWG), extend the
M6 wires to their designated connections. Refer to the diagram
below for wiring and fusing information.
Operation:
Flash Mode / RED:
Apply +VBAT to the RED wire to activate the lighthead in “flash mode”.
With flash mode activated, you may change the flash pattern using
Scan-Lock™.
Low Power / VIOLET:
The type of switch used is dependant on how the operator wishes the
Hi/Lo feature to function:
Latching Mode: By applying +VBAT to the VIOLET wire for less than 1
sec., the lightbar is “latched” into low power operation. The light must
be turned off and then back on to restore normal, Hi power operation.
(A Momentary Switch is Preferred)
Level Mode: Applying +VBAT to the VIOLET wire for more than 1 sec.
holds the lightbar in low power mode until voltage is removed (a toggle
switch is preferred).
SYNC / GREY
To SYNC two lightheads, configure both lightheads to display the same
Phase 1 (Simultaneous) pattern. Turn the power off and connect the
GREY wire from each lighthead together. When the lightheads are acti-
vated their patterns will be synchronized. To configure two lightheads
to alternate their patterns, advance the pattern of either lighthead to
Phase 2 (Alternating) of the pattern.
Scan-Lock™ / WHT/VIO / Flash Pattern Selection:
This feature allows the user to select from several available flash
patterns.
The lighthead must be on for Scan-Lock™ to work.
TO CYCLE THROUGH ALL PATTERNS: Apply +VBAT to the WHT/VIO wire for less
than 1 second and release. To cycle backward through patterns apply +VBAT to the
WHT/VIO wire for over 1 second and release.
TO SET A PATTERN AS DEFAULT: Allow the pattern to run for more than 5 seconds.
The lighthead will flicker slightly when the pattern locks in. This flicker may be difficult to
see with some patterns. The lighthead will now display this pattern when activated.
TO RESET TO THE FACTORY DEFAULT PATTERN: Turn off power. While applying
+VBAT to the WHT/VIO wire, turn power on. This will reset the lighthead to it’s factory
default flash pattern.
IMPORTANT! It is the responsibility of the installation technician to make sure
that the installation and operation of this product will not interfere with or
compromise the operation or efficiency of any vehicle equipment!
