Other Connections to the Omni Mega
All other connections to the Omi Mega beacon are through a single multi pin connector fitted to the
base of the beacon. A plug and 1.5m of connection cable is supplied with the beacon. The
connection diagrams of the connector and cable are shown in Appendix E. The electrical
specification is provided in the specifications section of this manual.
3.2.1 Hardwire Synchronization
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.
Where GPS synchronisation is required the Vega VSU-29 GPS sync unit can be connected to the
synchronising wire of the Omni Mega. Alternatively a GPS sync pulse can be generated from a
VegaWeb monitoring unit when it is fitted with a GPS unit.
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 167-295). The
Omni Mega will only operate in Slave Sync mode when connected to the signal inverter module.
Vega 12V products that generate or receive hard-wired sync, such as the VSU-29 and the VLB-44,
etc, can be safely connected to the sync wire on the Omni Mega.
3.2.2 Omni Mega Monitor.
The Omni Mega monitor outputs consists of a normally-open (NO) and normally-closed (NC)
contact that are used to provide an indication when the Omni Mega is able to operate or not able to
operate. This alarm monitors the current and the supply voltage as well as internal functioning of
the beacon. These contacts are electrically isolated from the power supply and the rest of the
beacon circuitry.
The two output signals, Beacon FAIL and Beacon OK, are always in opposite states from each
other. A relay contact is provided for each signal and they share a common contact.
The Beacon FAIL relay contact is closed to the common when the Omni Mega is in any of the
following states:
•
For a few seconds at first power-up.
•
No voltage or low voltage is present.
•
No LED current or low current is detected when the Omni Mega LED
’s should be on.
•
Alarm is being tested using Operation mode 1-5-007 (Clause 5.5.6).
To use the Beacon FAIL and/or Beacon OK signals, first connect the common signal to a supply
rail, e.g. battery negative. A voltage from 0 to 30VDC can be applied to these contacts. The
maximum current the outputs can handle is 2A and an open circuit maximum voltage of 30VDC.
For additional details refer to the specification section.

Omni Mega “Beacon ON” Output
The Omni Mega ”Beacon On” output is a solid-state relay and will operate when the beacon is
awake and the LEDs are on. Please note that the relay will not follow the flash character. It will be
