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 below, mark the mounting and wire hole
locations onto the proposed mounting surface. Drill two, .250"
diameter mounting holes and a .625" (minimum) wire access
hole into the mounting surface.
2. Place the gasket into position on the rear of the M4 assembly.
Insert the slotted hole screw grommet through the mounting
holes on the M4/Gasket assembly. Feed the M4 wires through
the wire access hole in the mounting surface. Press the M4/
Gasket/Grommet assembly onto its mounting location so that it
is flat against the mounting surface.
3. 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. DO NOT
OVERTIGHTEN!
4. Using appropriately sized wires (minimum 18 AWG), extend the
M4 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 depends on how the operator wishes the
Low Power feature to function: Latching Mode: By applying +VBAT
to the VIO wire for less than 1 sec., the lighthead is “latched” into
low power. The unit must be turned off and then back on to restore
normal operation. (momentary switch) Level Mode: Applying
+VBAT to the VIO wire for more than 1 sec. holds the lighthead in
low power mode until voltage is removed. (toggle switch)
SYNC / GREY
To SYNC two lightheads, configure both lightheads to display the
same Phase 1 (Simultaneous) pattern. Turn the power off and con-
nect the GREY wire from each lighthead together. When the light-
heads are activated 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 current
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!
