All wiring should be stranded and a minimum of 20 AWG. The positive line must have an in-line 3 AMP slow-blow fuse for each directional as
shown in FIGURE 3. Isolate the yellow and blue wires when not in use.

Flash Patterns
To select a flash pattern, apply power to the RED (single color models) or WHITE or both RED and WHITE (dual color models) wires.
Apply blue to black wire for flash pattern change:

factory default pattern
5+ secs.

Dimming Function:
Connect blue wire to Red power wire.
Synchronization:
The CD3511 series is capable of syncing with other compatible CODE 3 products by following these steps:
Step 1.
Set the desired flash pattern on each unit individually. It is also strongly recommended that the same style of flash pattern be used on
all units to produce the most effective warning pattern. NOTE: Phases A and B for each style of flash pattern in the table denote the relative
timing between units connected in a synchronizing installation. To operate simultaneously, each unit must be set to the same phase (A +A or
B + B); to operate alternately, units must be set to have the opposite phase (A + B or B + A).
Step 2.
Connect the yellow sync wires together and check that the units are flashing in a synchronized manner as expected. If a pattern
on one unit appears incorrect, the blue pattern select wire can be used to cycle forward or backward on that individual unit until the correct
pattern is selected. NOTE: This will only change the pattern in the one unit and will not affect the other units connected to the yellow sync
wire.
NOTE: CD3511 series does not sync with SD24 models.
