Installation:
IMPORTANT! It is the responsibility of the installation technician to make sure
that the installation and operation of this product will not interfere with or
compromise the operation or efficiency of any vehicle equipment!
Caution: Permanent mounting of this product will require drilling. It is
absolutely necessary to make sure that no other vehicle components could be
damaged by this process. Check both sides of the mounting surface before
starting. If damage is likely, select a different mounting location.
Wiring:
WARNING!
All customer supplied wires that connect to the positive terminal
of the battery must be sized to supply at least 125% of the maximum operating
current and FUSED at the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!
Using appropriately-sized wire, extend the RED (Power) wire to +12VDC. Fuse this
wire @ 3A. Extend the BLK (Ground) wire to chassis ground.
The following sections outline the Rota-Beam’s Scan-Lock™ and SYNC™ features.
Connect these wires to +12VDC are fuse @ 1A.
Scan-Lock™ (White/Violet):
Note that the lighthead must be on to use the ScanLock feature except where
noted.
To advance to the next flash pattern - Apply +12VDC to the WHT/VIO wire for less
than 1 second and release.
To cycle backwards through the flash patterns - Apply +12VDC to the WHT/VIO
wire for more than 1 second and release.
To reset to the factory default flash pattern - Turn off power to the lighthead. While
applying +12VDC to the WHT/VIO wire, turn power to the lighthead on. Continue to
apply voltage to the WHT/VIO wire for 5 seconds. The default pattern will now be
active.
NOTE: A Normally Open momentary switch is suggested to activate the Scan-
Lock™ wire.
SYNC (Grey) - To SYNC two lightheads, configure both lightheads to display the
same Phase 1 pattern. With the power off, connect the Grey wires from each
lighthead. When the lightheads are activated, their patterns will be synchronized. To
configure the two lightheads to alternate their patterns, advance the pattern of either
lighthead to the Phase 2 mode of the current pattern. Remember, Phase 1 patterns
ALWAYS alternate with Phase 2 patterns!
Hi/Low Intensity (Violet) - This feature allows the user to step the unit down to low
power operation for nighttime use. Apply positive voltage to the VIOLET wire to put
the lighthead into low power. Remove the voltage from the VIOLET wire to restore
normal high power operation.
CAUTION! DO NOT LOOK DIRECTLY AT THESE LED’S WHILE THEY ARE ON.
MOMENTARY BLINDNESS AND/OR EYE DAMAGE COULD RESULT!

IMPORTANT! Before returning the vehicle to active service, visually
confirm the proper operation of this product, as well as all vehicle
components/equipment.

1.
Using the dimensions shown, mark off and drill the four 1/4” diameter mounting
holes and the 1” wire hole into the mounting surface. Check measurements
before drilling.
2.
Install the screw grommet flange into the mounting holes then install a rubber
grommet (customer supplied) into the wire hole.
3.
Using appropriately sized wires (minimum 18 AWG wire), extend the lighthead
wires to their appropriate connections. Fuse the positive connections at 3
Amps and test operation of lighthead before securing it to vehicle.
4.
Position the lighthead onto the mounting surface and secure to the vehicle
using the four #6 x 1-1/2” sheet metal screws.
