Mounting the VLB-67 Beacon
The base of the VLB-67 Beacon has been designed for 3 or 4 holes
mounting on a 200mm diameter PCD. The base has through holes sized
to take 316 Stainless steel M12 (1/2” UNC) bolts or rod. The mounting
holes are fitted with stainless inserts to prevent compression of the
plastic base when the fasteners are tightened.
7.3.1 Levelling the Beacon
The mounting surface needs to be level to ensure the VLB-67 has a
horizontal beam. This can be checked by placing a builder’s level on the
mounting surface then moving the level 90 degrees at a time checking
the surface is level in at least two directions. If the mounting surface is
not level take appropriate measures to ensure it is level before
permanently installing the beacon.
Alternative levelling mechanisms can be used, such as adjustable rods.
If the mounting surface cannot provide 3 or 4 holes mounting on a
200mm PCD an adapter plate would be required.
When the beacon is mounted on a floating structure (buoy), the beacon needs be level when the
buoy is floating freely in calm air and water.
7.3.2 Mounting Structure
Movement of the mounting structure needs to be constrained to a level where the VLB-67 beacon
can be visible to the intended user. This includes the sway on a fixed structure and the roll of a
buoy.
The vertical divergence of the VLB-67 beacon is 7 degrees. At ± 3.5°the intensity is at 50%, and at
± 7.0°the intensity is approximately 10% of the peak intensity

VLB-67 Factory Options
All options are factory installed and must be included in the purchase order. None of the options
can be fitted in the field after the VLB-67 beacon has been manufactured.
8.1
Hardwire Synchronization
The VLB-67-SA Stand Alone beacon comes with the hardwire sync wire included in the power
cable. Because of the nature of the self-contained beacon no external wiring is supplied with the
standard option.
The Vega hardwire sync operates as a positive to negative transition. The start of the flash
character can be delayed between 0 and 9.9 seconds should it be desirable to have a different
start time to other beacons connected to the synchronising wire.
The sync wire can provide additional control such as turning the beacon off when grounded. This
can be useful when a standby light option is required. Refer to Section 4 Clause 5.5.1.
Other beacon manufacturers may not use a negative transition signal and will not be able to
synchronise with Vega Beacons. If there is a requirement to synchronise with beacons with a
positive transition signal it may be possible to use the signal inverter module (Vega 167-600). The
VLB-67 beacon will only operate in Slave Sync mode when connected to the signal inverter
module.
