Installation and Operation Instructions
SD24 LOW PROFILE LED HEAD
The SD24 Series provides a compact high intensity
LED warning signal. The SD24 Series features 12
or 24 VDC operation, 16  ash patterns, the ability to
synchronize with additional units and a waterproof
driver module that is in-line with the 9’ cable.

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 ash 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 ash 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 ash pattern to be changed when desired.
Note: Do not connect the BLUE wire to - Ground.
It will disrupt the ash 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 either +V or GROUND (GND).
The YELLOW wire makes the head re AT THE SAME TIME or ALTERNATE with the other heads in the system.
Heads with YELLOW connected to +V re at the same time.
Heads with YELLOW connected to GND re 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!

POWER-UP RESET:
After installing the system it is best to do a POWER-UP RESET the rst time
to ensure all heads are in sync.
Touch BLUE wires to +V (RED wire) while applying power.
Release BLUE wires. All heads will reset to Pattern #2.
If you have installed a pattern select push-button, press and hold
pattern select while turning power switch ON.
To select a ash pattern, touch BLUE to +V or press pattern select switch to
increment the ash pattern. The heads will remember the selected pattern
even if power is removed.

STANDARD PATTERNS:
The 3510 ships with sixteen patterns enabled. Standard patterns 1 through
8 are compatible with older BULL LED™ and HIDE-A-LED™ products.
CYCLE PATTERNS:
You may revert to patterns 1 through 8 by following this procedure:
1) Touch BLUE wires to +V (RED wire) while applying power.
If you have installed a pattern select push-button, press and hold
pattern select while turning power switch ON.
2) Hold BLUE wires on +V for 5 SECONDS (heads will not be ashing
during this time). After 5 SECONDS the heads will ash once or twice to
indicate the ash pattern list that has been selected:
ONE FLASH = Standard Patterns only.
TWO FLASHES = Standard + Cycle Patterns.
3) Remove the BLUE wires from +V (or release push-button).
You may switch the pattern set at any time as many times as you wish. All
heads will remember the pattern set that was selected even when power is
removed.
Flash Patterns:
HEAD NOT FLASHING:
Check the RED and BLACK wires for a reversed connection. (Reverse
connection will not damage the unit). Check RED and BLACK wires for
either a bad splice or a corroded ground connection.
HEADS NOT SYNCHRONIZING:
Check for a short circuit on the BLUE wire to either +V or GROUND.
Saltwater on the wire connections will short circuit the sync signal on the
BLUE wire. Check for non-functional heads in the system. If any one of
the heads has a bad GROUND connection it can cause the sync signal to
become corrupted. If any one of the heads has it’s RED and BLACK wires
reverse connected it will corrupt the sync signal.
FLASH PATTERN CHANGING:
If the ash pattern changes on it’s own there may be an intermittent short
between the BLUE wire and +V. Check for water in the wiring connections.
If any one of the heads in the system has an intermittent GROUND
connection it can also cause the ash pattern to change.
