L-864 FLASHHEAD/BEACON INSTALLATION AND GROUNDING
1.
Verify that the mounting surface is free of debris.
2.
Align the four mounting holes in the base of the beacon with the holes in the tower or pedestal’s
mounting plate.
3.
Leaving the hardware assemblies loose, secure the beacon with ½-inch stainless steel or galvanized
hardware (part # 5991740).
4.
With the light engine secured by the two latches on the base, place a level on the beacon’s top plate and
verify that it is level in two directions.
Note:
Flash Technology’s “T”- Level (optional part # 11000013455)
has two vials to simplify installation.
5.
If the beacon is not level, add stainless steel shim material or washers (stainless steel or galvanized) as
necessary to level the beacon.
6.
Tighten the hardware once the beacon is level in both directions. Fully tighten the hardware and verify
that the beacon is level. If necessary, loosen the mounting hardware and repeat Step 5 until the beacon is
level with the hardware fully tightened.
7.
Connect a minimum 8 AWG grounding wire to the pre-installed grounding lug on the beacon base
exterior. Connect the other end of the wire directly to tower steel, collective buss bar or the customer’s
preferred location. Use an anti-corrosive agent on all terminal ends.
OL2 INSTALLATION AND WIRING FOR A0 TOWERS
A0 towers use a double L-810 (OL2) as the beacon. Images of the various OL2 styles are shown below.
There are several options in which to mount an OL2.
1.
If clean steel is available with no worry of or indication of transmitting issues from other sources, a
mounting bracket can be used in combination with a marker cable. Flash Technology provides a bracket
(F3877103 Bracket Mounting Kit OL2 Extended) that is screwed into the threaded hole in the bottom of
the OL2 and mounted on the base plate at the top of the tower. The mounting bracket is shown below.
The cable is best secured using the 2,3,4 tape method described in “SECURING THE CABLE” section below.
