IMPORTANT! Read all instructions before installing and using. Installer: This manual must be delivered to the end user.
WARNING!
Failure to install or use this product according to manufacturer’s recommendations may result in property damage, serious injury, and/or
death to those you are seeking to protect!
1. Proper installation combined with operator training in the use, care, and maintenance of emergency warning devices are essential to
ensure the safety of emergency personnel and the public.
2. Emergency warning devices often require high electrical voltages and/or currents. Exercise caution when working with live electrical
connections.
3. This product must be properly grounded. Inadequate grounding and/or shorting of electrical connections can cause high current arcing,
which can cause personal injury and/or severe vehicle damage, including re.
4. Proper placement and installation is vital to the performance of this warning device. Install this product so that output performance of the
system is maximized and the controls are placed within convenient reach of the operator so that s/he can operate the system without losing
eye contact with the roadway.
5. It is the responsibility of the vehicle operator to ensure daily that all features of this product work correctly. In use, the vehicle operator
should ensure the projection of the warning signal is not blocked by vehicle components (i.e., open trunks or compartment doors), people,
vehicles or other obstructions.
6. The use of this or any other warning device does not ensure all drivers can or will observe or react to an emergency warning signal. Never
take the right-of-way for granted. It is your responsibility to be sure you can proceed safely before entering an intersection, drive against
tra󰀩c, respond at a high rate of speed, or walk on or around tra󰀩c lanes.
7. This equipment is intended for use by authorized personnel only. The user is responsible for understanding and obeying all laws regarding
emergency warning devices. Therefore, the user should check all applicable city, state, and federal laws and regulations. The manufacturer
assumes no liability for any loss resulting from the use of this warning device.
Do not install and/or operate this safety product unless you have read and understand the safety information contained in
this manual.

Flash Pattern Selection:
The light head ash pattern may be changed by touching the Blue wire to ground for the following intervals (while the light head is ashing):
- A quick tap will increment by one pattern.
- Hold until the unit lights, then turns o󰀨 to go to the previous pattern.
- Hold until the unit lights, then turns o󰀨, then lights again to reset to the factory default pattern.
- Hold until the unit lights, turns o󰀨, lights, then turns o󰀨 again, then goes o󰀨 again to set to steady burn.
Wiring Instructions:
Wire as shown in FIGURE 2. All wiring should be a minimum of 18 AWG. The
positive line must have a slow blow 5 amp fuse. Routing the ground wire directly
back to negative battery terminal is recommended. Pack dielectric grease, such
as Dow Corning 4, around each electric connection exposed to moisture or the
ambient environment. Isolate any unused wires.
Caution! When drilling into any vehicle surface,
make sure that the area is free from any electrical wires,
fuel lines, vehicle upholstery, etc. that could be damaged.
Mounting Instructions:
Important! This unit is a safety device, and it must be
connected to its own separate, fused power point to as-
sure its continued operation should any other electrical
accessory fail.
Select a at mounting surface with optimal visibility to oncoming tra󰀩c. Using the
product as a template, drill two holes matching the holes in the unit. Secure unit in
place as shown.

FIGURE 2
Synchronization:
The directional is capable of syncing with other compatible ECCO products by following the steps below:
1. Set the desired ash pattern on each unit individually. It is also strongly recommended that the same rate and style of ash pattern be used on all synced units to
produce the most e󰀨ective warning pattern.
NOTE: 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 ashing 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 a󰀨ect the other units connected to the yellow sync wire.
