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 manufacturers 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.

A variety of ash patterns may be chosen for the light head. The Dual Stack light heads are split horizontally and vertically providing 4 separate lighted areas in each
light head that may be chosen to ash up-down, right-left, diagonally, and to rotate. The Split Dual Color version also provides di󰀨erent colors for the upper level versus
the lower level.
A separate ash pattern may be assigned for the power wires red, white, or both connected together and the pattern operated depending which wire or wires are ener-
gized. Power the red or the white wires (or both together) then use the pattern select blue wire (touch to ground) to select the chosen ash pattern from one of the lists
below.
Note: The split dual color light heads have a separate ash pattern list.
See the legend at the top of the pattern lists for compliance with various standards.

Wiring Instructions:
RED: Positive, (5A fuse required)
WHITE: Positive, (5A fuse required)
BLACK: Negative
BLUE: Pattern select to negative -- Dim control to positive
YELLOW: Synchronized Function (Up to 32 units can be Synchronized)
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.
(Up to 32 light heads can be Synchronized by connecting their yellow wires).
When the yellow wires of the light heads are connected together, the group with Ph1 ash patterns will ash simultaneously. If the light heads in the second group are
set to Ph2 ash patterns, they will ash alternately with the rst group. To simplify the set-up of a synchronized installation, the following process is recommended:
1. Before connecting the yellow wires together, choose the desired ash pattern for each light head. The patterns chosen must have the same ash rate for all light
heads intended to be synchronized. (By denition a 75fpm light head will not sync with at 120fpm light head) To avoid confusion set each light head in-
dividually to the chosen ash pattern using the blue pattern select wire. Ph1 light heads will alternate with Ph2 light heads and simultaneously with all other light
heads set to Ph1. Ph2 light heads ash simultaneously with all other light heads set to Ph2. It is also strongly recommended that the same style of ash pattern
be used on all heads to produce the most e󰀨ective warning pattern.
2. Connect the yellow synchronization wires together and check that the light heads are ashing in a synchronized manner as expected. If a pattern for one light head
appears to be wrong, keep the yellow wire connected and use the blue pattern select wire to cycle forward or backward for that individual light head until the cor-
rect pattern is selected. Once that is completed verify the light head is synchoronized correctly.
The light head intensity may be reduced if necessary. The Blue wire when connected to positive will reduce the intensity to 25% for SAE patterns. NOTE: The blue wire
must be disconnected from any voltage when not activating DIM nor changing ash patterns.
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):
NOTE: The blue wire must be disconnected from any voltage when not activating DIM nor changing ash patterns.
- When the light head signal becomes steady, disconnect the Blue wire and the ash pattern will increment by one pattern.
- When the light head signal becomes steady, then goes o󰀨, disconnect the Blue wire and the ash pattern will decrement by one pattern.
- When the light head signal becomes steady, then goes o󰀨, then becomes steady again, disconnect the Blue wire and the ash pattern will reset to the factory default
pattern.
- When the light head signal becomes steady, then goes o󰀨, then becomes steady again, then goes o󰀨 again, disconnect the Blue wire and the ash pattern will become
set to the steady burn mode.
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.
Installation and Mounting:
To mount the light head, use the bezel as a template to mark the mounting holes. The supplied self-tapping #6 x 0.75”
screws typically use 0.125” diameter holes but this may vary depending on the type of material and the thickness being
tapped. Provide a minimum 0.50” diameter hole for the wires. Grommet the hole if possible and seal with RTV sealant.
It is important to note:
The light head has 2 small round holes covered with vent membrane that must face downward when mounting
the light head.

The LED Surface Mount series light head has been thoroughly factory tested. If any of the the device functions fail, please check the following:
1. Be sure the power source is activated, then check all connections both positive and ground at the light head (to assure no open or shorted circuits).
2. Permanently connecting the Blue programming wire to ground will disable the light head, no matter what the programmed ash pattern.
3. If the Dim function does not operate, verify the Blue wire is connected to positive.
4. If the sync function is not being used and the light head is functioning erratically, verify the Yellow wire is not connected to positive or ground.
