Ecco EB7260 Series Installation And Operation Instructions Manual page 2

Flash Pattern Selection:
Flash patterns are selected by touching the blue wire to the black ground (-) wire for less than a second. Holding the blue and black wires for longer than a second toggles
to the preceding flash pattern.
Synchronization:
Syncing capabilities are available with all compatible ECCO products via the yellow wire with the flash patterns indicated in the charts below:
1. Determine the desired style of flash pattern for each unit and set each unit individually (without the yellow wires connected together) to avoid confusion. 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).
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.
3. If the yellow wire is unused, leave unconnected and insulated.
