M7 Sequencing & Phasing: The M7
lighthead has 2 sets of 9 LEDs. These
sets cycle through the sequences
shown below:
1 2
NOTE: Phase 1 and Phase 2 patterns are visually indistinguishable from each other
unless two or more lightheads are SYNC'd together.
Installation and Wiring:
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 M7
assembly. Insert the slotted hole screw grommet through the
mounting holes on the M7/Gasket assembly.
4. Feed the M7 wires through the wire access hole in the
mounting surface. Press the M7/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 M7 wires to their designated connections. Refer to the
diagram below for wiring and fusing information.
Operation:
Flash Mode / RED:
Apply +12V to the RED wire to activate the lighthead in “flash
mode”. With flash mode activated, you may change the flash
pattern using Scan-Lock™.
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.
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 positive voltage
to the WHT/VIO wire for less than 1 second and release. To cycle
backward through patterns apply positive voltage 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 positive voltage 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!
