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 M4 assembly. Insert
the slotted hole screw grommet through the mounting holes on the M4/
Gasket assembly.
4. 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. 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!
5. 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”.
In flash mode, 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. (A momentary switch is preferred)
Level Mode: Applying +VBAT to the VIO wire for more than 1 sec. holds the
lighthead 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 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.
NOTE: You can also program the 2 banks of LEDs inside the lighthead
to flash in different configurations (See M4 Sequencing and Phasing).
Scan-Lock™ / WHT/VIO / Flash Pattern Selection:
This feature allows the user to select from several available flash patterns.
The lighthead must be switched 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!
