3.2.2 Mounting location

The location selected must be sufficiently rigid to support the weight of the total installation (approx. 2 lbs)

and at the same time consider vibration, exposure to surrounding hazards, such as equipment movement,

doors openings, personnel traffic, etc. The bracket should only be mounted to a flat surface at least

as big as the bracket. Mounting to a rail or post is not recommended.

Also to be considered in selecting a location for installation is the harmful effect that certain corrosive

vapors might have on the beacon. Under no circumstances should a location be selected for installation

where the beacon would be jeopardized by any foreign articles being temporarily or permanently

positioned during “at sea” or “in port” activities.

Do not mount or store the beacon within 1 meter (3.3 ft) of strong magnetic (such as loud speakers) or

electrical (such as radar or high power radio transmitter) fields. The beacon should not be mounted closer

than 1 meter (3.3 ft) to a navigation compass.

In order to maintain the required covert operation, the ThunderBird SSAS mounting location should be

hidden from the view of most personnel and all passengers and guests. Suitable locations include inside

an equipment closet or cabinet, under the navigation bridge and inside a closed equipment rack.

The bracket can be mounted in any orientation; however, the beacon controls and system connections are

designed for vertical installation. When selecting a mounting location the following should be carefully

considered:

Routing of switch wires/cables. (Connects to top of mounting bracket.)

Routing of RG-8U coaxial antenna cable. (Connects to top of beacon.)

Routing of GPS interface cable. (Connects to top left part of beacon.)

Accessibility to beacon control switch. (Top right part of beacon.)

Visibility of test and Xmit LED’s. (Top left part of beacon.)

3.2.3 Hardware

Use three stainless steel pan head fasteners to secure beacon mount to surface. Size 3/16” or #10 bolts

can be used. (Not Supplied)

3.2.4 Installing the beacon in the bracket

The mounting bracket is keyed to prevent the beacon from being installed backwards. Install the

ThunderBird SSAS with the front label facing out. The strap should be tightened to secure the beacon

snugly in the bracket. Connect the 2-Pin waterproof connector on the left side of the beacon (see Figure

11).

3.2.5 Connecting the beacon to a GPS receiver via the optical interface (IR transmitter)

Your beacon comes with a NMEA GPS optical interface cable (transmitter plug with lead wires) that should

be connected to the ship’s GPS system. The IR transmitter plug attaches to your beacon, via the keyed

blue bezel on the top left of the beacon. The cable can be routed through the hole in the upper left corner

of bracket. The lead wires attach to the ship’s GPS system via the NMEA 0183 connector from your GPS

receiver. The black lead wire with white stripes should be connected to the positive transmitter pin (Data

Out). The black wire should be connected to the negative pin (Ground).

NOTE: The baud rate output for your GPS receiver NMEA 0183 should be 4800. Consult your GPS

manufacturer for correct installation.

3.3 Activation switch installation

Per IMO’s SOLAS Chapter XI-2, Regulation 6: Ship Security Alert System:

Paragraph 3.1: “The ship security alert system shall be capable of being activated from the navigation

bridge and in at least one other location;”
