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.
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 different 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.
(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 denition 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 effective 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 off, disconnect the Blue wire and the ash pattern will decrement by one pattern.
- When the light head signal becomes steady, then goes off, 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 off, then becomes steady again, then goes off again, disconnect the Blue wire and the ash pattern will become
set to the steady burn mode.
