Typical ‘Alarm Output’ connection to peripheral device via external relay
c. Omni-Directional Antenna
The omni-directional-antenna is a marine grade antenna which has the capability of receiving a Seasafe
Transmitter signal within 360 degrees, provided the Transmitter is within signal receiving range. The
higher this antenna is mounted on the vessel, the greater the receiving range of the system. Therefore
the omni-directional antenna should be mounted at the highest practical point on the vessel. The antenna
should be mounted using the antenna mounting bracket (supplied) and stainless steel fasteners (not
supplied). The coaxial antenna cable should be run from the antenna to the Receiver ensuring that the
cable is not exposed or in a position to be damaged in any way. The coaxial cable plug must be
connected to the receiver input connector marked “omni-directional antenna”.
d. Collapsible Directional-Antenna
The directional or Yagi antenna is a portable hand-held marine grade aluminium antenna. It should be
safely stowed in the vessel folded up where it is easily accessible in case of an emergency. In the event
that it is required to use this antenna, it should be removed from its plastic sleeve and the folded elements
should be folded out for use. The coaxial cable attached to the antenna must be connected to the input
marked “directional-antenna” on the receiver. The “directional-antenna” may be mounted on the vessel in
a semi-permanent position utilising the optional “mast-mount” adapter.
This aluminium adapter is bolted to the vessel in an appropriate position as high as possible and the
unfolded antenna simply ‘clicks’ into the adapter. It may be removed by simply ‘un-clicking’ it from the
adapter if and when required.
