Wiring:
The wiring for the permanent mount Microbar is as shown in Figure 5. All wiring
should be a minimum of 18AWG. The positive line must have a 5 amp fuse, as
shown. A switch may be used to control the on/off function.
FIGURE 5
Flash patterns can be selected on a permanent mount microbar by
touching the blue wire to the black ground wire for less than a second.
Contacting the blue and back wires for longer than a second toggles to
the preceding flash pattern. The VM models have flash pattern select via
a momentary switch on the cigarette plug
Flash Mode Selection:
SYCHRONIZATION:
The permanent mount microbars sync with compatible ECCO
products via the yellow wire:
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.
