IMPORTANT! The lightbar should be a minimum of 16" from
any radio antennas!
Permanent Mounting / Bracket or Stud Mount:
This mounting style requires removal of the headliner. There may be a roof
support member that runs from the drivers to the passengers side of the
vehicle. Do not drill through this member.
Caution: Permanent mounting of this product will require drilling. Be
absolutely 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.
1.
Insert the 2 stud mounts (or brackets) under the lip in the bottom of the
extrusion. (rounded end first) and pivot the bracket so that the other end
slides under the other lip in the extrusion (Fig. 1). The mounting hardware
must be clear of the lightbar to get the bracket into the extrusion.
2. Make sure that the brackets are sitting all the way at each end of the
extrusion, then secure them with the supplied allen set screws.
3. Place the lightbar in the exact mounting location. Mark the location of the
2 (or 4) mounting holes onto the mounting surface, and the area for the
wire passage hole. This hole should be located directly below where the
wires exit the extrusion.
4. Remove the lightbar and drill the mounting holes (Fig. 2) as well as the 5/
16” dia. wire passage hole. De-burr all the holes and install a rubber
grommet (customer supplied) into the wire passage hole.
5. Route the wires through the grommet and to the necessary switches and
power source as shown in the wiring diagram.
6. Secure the lightbar to the vehicle using the hardware provided. From the
underside of the mounting surface, apply RTV around each mounting
hole and the grommeted wire passage hole.
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!
Before returning the vehicle to active service, visually confirm the proper
operation of this product, as well as all vehicle components/equipment.
Temporary Mount (Magnetic or Suction Cup):
WARNING: The use of any magnetically mounted warning device on the
outside of a vehicle in motion is not recommended and is at the sole risk
and responsibility of the user.
Magnetic/suction: Thoroughly clean
the proposed mounting surface prior
to mounting. For suction cup
mounting, wipe the suction cup
clean, place the beacon onto its
mounting surface and apply gentle
pressure to ensure a good seal has
been achieved. The Magnetic/Suction Cups mount the same way as standard
suction cups but are best suited to a flat, steel surface. Magnetic: Place the
lightbar onto the mounting surface and plug it into the vehicle cigar lighter.
NOTE: Insert into the base the same as the permanent mount brackets.
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 the load.
DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
Scan-Lock™:
To operate Scan-Lock™, switch the lightbar on. Magnetic and Suction mount
models use a momentary switch on the cigar plug instead of a Scan-Lock wire.
TO CHANGE PATTERNS: To cycle forward apply +12 VDC to the WHT/VIO
wire (or switch) for less than 1 second and release. To cycle back to the
previous pattern apply +12 VDC to WHT/VIO wire for over 1 second.
TO CHANGE THE DEFAULT PATTERN: When the desired pattern is
displayed, allow it to run for more than 5 seconds. The lighthead will now
display this pattern when initially activated.
TO RESTORE THE FACTORY DEFAULT PATTERN: With power off, apply
+12 VDC to the WHT/VIO wire (or switch). While continuing to apply power to
Scan-Lock™ turn lighthead(s) on. The factory default pattern will be displayed.
