Dimming Feature - Ecco 5500 Series Installation And Operation Instructions Manual

Wiring:
Important! Disable power before wiring up the microbar.
The wiring for the permanent mount microbar is as shown in Figure 6. 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.

Flash Pattern Selection:
To select a flash pattern, apply power to the RED or WHITE or both RED
and WHITE wires. (WHITE wire is for dual color only). Momentarily
touch the BLUE wire to the BLACK wire (ground) for less than 1 second
to advance to the next pattern. To go back to the previous pattern,
momentarily touch the BLUE wire to the BLACK wire for approximately
2 - 3 seconds. To force the flash pattern to STEADY, momentarily touch
the BLUE wire to the BLACK wire for approximately 5 seconds. When
Vacuum-Magnet Mount is being used, the BLUE wire is connected to
ground via the momentary switch on the cigarette plug as shown in
FIGURE 2. For more detail about flash patterns, please see the SINGLE
and DUAL COLOR FLASH PATTERN TABLES below.
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.

DIMMING FEATURE:

To activate the dimming feature of this microbar, attach the BLUE wire to the
RED wire (+BATT).
