FIGURE 2
Drill a 11/16” diameter hole in the mounting surface to pass the
cable through.
Use the provided #4 mounting screws to attach the SD24
™
to the
mounting surface.
The drilling template below can be used to mark the hole locations.
Use silicone sealant around the cable and screw holes to prevent
moisture from entering body panels.
Note:
There are electronic components in the power module.
Do not
drill into the power module. Do not bend the power module.
Electrical Connections:
The cable on the SD24™ is long enough to run across the front or the rear of a vehicle. Trim the cable shorter if needed. The wiring diagram on page 3
shows a typical install.
RED:
Connect to +V through an ON/OFF switch.
The use of a fuse located close to the voltage source is recommended. Size the fuse according to the number of heads used in the system. 18AWG or larger
wire is recommended.
DO NOT CONNECT THIS UNIT TO VOLTAGES HIGHER THAN 32 VOLTS DC!
BLACK: - GROUND
Connect to - GROUND vehicle chassis.
18AWG or larger wire is recommended.
BLUE:
Flash pattern SYNC and SELECTION wire.
If you wish to have all the LED heads synchronize
their flash timings and patterns with each other then all the BLUE wires must be connected together (64 Heads Maximum).
The BLUE wire is also used to select the flash pattern.
Touch the BLUE wire to +V to select the next pattern in the FLASH PATTERN LIST. The BLUE wire can also be run to a momentary push-button located on
the dashboard to allow the flash pattern to be changed when desired.
Note: Do not connect the BLUE wire to - Ground.
It will disrupt the flash pattern sync signal.
YELLOW: Alternating / Simultaneous selection.
The BLUE wires of all SD24
™
heads must be connected together for the alternating /simultaneous function to work.
Connect to V or GROUND (GND).
The YELLOW wire makes the head fire AT THE SAME TIME or ALTERNATE with the other heads in the system.
Heads with YELLOW connected to +V fire at the same time.
Heads with YELLOW connected to GND fire at the same time.
Heads with YELLOW connected to +V will ALTERNATE with heads that have YELLOW connected to GND.
The YELLOW wire has no function in STEADY ON mode.
The SD24™ will also synchronize with any BULL LED™ or HIDE-A-LED™ head. The wiring colors and functions are identical.
Caution:
When drilling into any vehicle surface, make sure that the area is free from any electrical wires, fuel lines,
vehicle upholstery, vehicle support members, etc. that could be damaged.
!
DO NOT MAKE THE HOLES IN THE LENS LARGER OR USE LARGER
HARDWARE THAN WHAT IS PROVIDED! DAMAGE TO SEAL WILL
RESULT!
