Installing a Beacon
Site requirements
When choosing a location for the Beacon:
•
The foreground of the beacon must be free from obstacles like masts and poles.
•
Avoid a relatively large land path in front of the beacon.
•
The height of the beacon must preferably be the same as the height of the Mobile Station
onboard the vessel. If the beacon is installed at a significantly higher position, the use of a
beacon horn antenna type ATH-010B is recommended.
!
The beacon may not be installed in an explosion hazardous environment. For operation in
a zone 2 hazardous environment, an optional pressurisation unit is available.
Mounting the Beacon
!
Take measures to prevent falling down from the mast or other heights. Use a safety
harness.
The beacon should be mounted:
•
On a rigid stand or bracket.
•
Ideally in a position where the antenna has a 360° clear line of sight if an omni-directional
antenna is fitted. For the other antenna types a sector of approx. 140° clear line of sight,
which should include the work area, is adequate.
The beacon can be mounted in a ’U’-shaped bracket with three holes. See
on page 13 for the required dimensions. The U-shape allows the beacon to be
slid in the bracket, rather than lowering it from above. In this way it takes less effort to install the
beacon.
To mount the beacon in the bracket:
1. Slide the beacon in the mounting bracket.
Note:
There is only one position in which the beacon fits in the bracket. This is the position where
the connectors are facing when standing in front of the ’U’-shaped cut-out of the bracket.
2. Secure the beacon with three M8 bolts. Place a washer between the bolts’ head and
the mounting brackets of the unit. Use spring washers to secure the nuts. Preferably use
stainless steel bolts, washers and nuts.
To mount the antenna on the beacon:
1. Position the antenna such, that the red mark on the beacon and the red mark on the
mounting flange of the beacon antenna are aligned.
2. Mount the antenna with the four self-retaining M6 hexagon socket-head screws of the
antenna, using a 5 mm hexagon key.
!
Tightening the bolts if the antenna has not been properly positioned will damage the
antenna flange of the beacon.
