This beacon must be mounted in a normal, ‘dome-up’ position. The
beacon can operate at either 12 or 24 volts and will automatically
switch to whichever voltage is applied to the power wire.
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.
Permanent Surface Mount:
1. Use the base as a template and mark the three mounting holes off onto
the mounting surface. Remove base. In the center
between the three mounting holes, mark the
location of the wire access hole.
2. Drill mounting holes into the mounting
surface with a #16 drill bit. Drill the wire
access hole with a 3/8” drill bit. Remove
any burrs from the wire access hole and
install a rubber grommet (user supplied)
into the wire hole to protect the wires.
3. The base seal goes between the beacon
base and the mounting surface.
4. Feed the wires through the base seal and
then through the cable access hole. Place
the base on the mounting surface and align
the beacon mounting holes with the
mounting holes drilled in step 2. Secure the
beacon firmly to the mounting surface using
the supplied #10 mounting screws.
This beacon may be mounted using “J”
hooks. Be sure to use the correct “J” hook mounting holes as shown
above.
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!
Temporary Mount (Optional):
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. 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 but are
best suited to a flat, steel surface. Magnetic: Place the beacon onto the
mounting surface and plug it into the vehicle cigar lighter. Temporary
mount models do not offer Low Power or SYNC.
Stud Mount (optional):
1. Remove the base gasket (if present) from the base and discard.
2. Route the wires through the hole in the center of the bracket. If desired,
a slot for an alternate wire path is provided in the base.
3. Secure the Stud Bracket onto the base using the hardware provided.
Drill wire passage and mounting holes using the information shown.
If an alternate wire path is used, drill
a .375 DIA wire passage hole. Install a
3/8” grommet (user supplied) in this
hole.
1” N.P.T. Pipe Mount (optional):
1. Remove the base gasket (if present) from the base and discard.
2. Feed beacon wires through pipe. Connect as shown in “Wiring”.
Screw the beacon onto the pipe, being careful not to pinch or strain the
wires. Hand tighten the unit onto the pipe.
Operation:
Low Power - Activate the VIOLET wire to put the beacon into low power
operation. Disable this wire to restore normal, high power operation
(toggle switch).
Photocell Low Power - If this beacon is equipped with photocell Hi-Low,
the beacon will automatically step down to low power at night.
Scan-Lock™ - Activate the RED wire to turn on the beacon. To cycle
forward through patterns, activate the WHT/VIO wire for less than 1
second and release. To cycle backward through patterns, activate the
WHT/VIO wire for more than 1 second and release. To choose a pattern,
allow it to run for more than 5 seconds. The beacon will now display this
pattern when active. To reset to the factory default pattern, turn off power,
activate the WHT/VIO wire, then turn power back on. Use a normally open
momentary switch to control Scan-lock™. Cigar cord models have a
momentary switch on the plug for Scan-Lock™ and an On/Off switch.
All beacons configured to display the Phase 1 mode of a pattern will flash
simultaneously. Any beacons configured to display the Phase 2 mode of a
pattern, will alternate with any Phase 1 beacons of the same pattern.
Sync - To sync two beacons, configure both beacons to display the same
Phase 1 pattern. With the power off, connect the GREY wires from each
beacon together. When the beacons are activated, their patterns will be
synchronized. To configure the two beacons to alternate their patterns,
advance the pattern of either beacon to the Phase 2 mode of the current
pattern.
Do not SYNC more than 8 beacons.
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.
NOTE: The cigar cord adaptor
is equipped with an 8 Amp fuse.
Use a replacement fuse with an
identical value.
