D * * * WARNING * * * THIS BEACON IS AUTHORIZED FOR USE ONLY DURING SITUATIONS WHERE THE SECURITY OF YOUR VESSEL IS UNDER THREAT OR HAS BEEN COMPROMISED AND POLICE ACTION IS REQUIRED DELIBERATE MISUSE MAY INCUR A SEVERE PENALTY ***Attention*** This beacon MUST be reprogrammed by an authorized ACR distributor prior to installation and use. Failure to do so will result in incorrect routing of a security alert. To ensure covert nature of the beacon, do not place the proof of registration label onto your SSAS beacon. [. . . ] This should be an open circuit (> 100 k. ) If not, check the switch wire connections to make sure the two wires from each switch are connected to different screws on the mounting bracket terminal block. Depress each switch (one at a time) while measuring the resistance between the two pins on the mounting bracket connector. The resistance should momentarily (as long as the switch is depressed) read a short (< 10. ) If the resistance never reads a short, verify all connections are per 3. 2. 4 and 3. 2. 5 above. 3. 4 3. 4. 1 Cross dipole antenna installation General information The cross dipole antenna is intended for operation far away from a ground plane. With this in mind, the location of installation should be carefully selected to keep the antenna as far from horizontal conductive (metallic) planes as possible (see Figure 12). The length of cable from the SSAS beacon to the cross dipole should be kept as short as possible. maximum) away from antenna to reduce stress on antenna connector (see Figure 12). A stainless steel 4 inch tall antenna mount is included with your SSAS kit. If the supplied bracket is not ideal for the desired mounting location, the cross dipole has a standard female 1" x 14 thread allowing it to be mounted to a variety of off-the-shelf brackets and masts. 6 Y1-03-0180 Rev. D 3. 4. 2 Mounting guidelines · · Minimum height above deck: Allowable obstructions: 10 feet (3 m) Obstructions are allowable only below the antenna. There should be no conductive (metallic) objects in the entire hemisphere above the antenna. Maximum: 100 feet (30. 5 m) * Contact the factory if longer runs or different coaxial cable is required. · Coaxial cable type: RG-8/U marine grade · Coaxial cable length: 3. 4. 3 Antenna assembly The antenna is shipped with the four elements removed from the housing. Before using the antenna, these elements must be assembled to the antenna housing. Slide the grooved end of the element into a hole in the side of the housing until it stops 2. Install and tighten appropriate set screw through hole in the bottom housing using included wrench 3. Pull lightly on the element to ensure it is tightly secured 1. 2. 3. ANTENNA ASSEMBLY FIGURE 3 3. 4. 4 Antenna installation Select mounting location using guidelines and general information above. Mounting to an existing spar or to a bracket attached to a mast is also acceptable. The antenna must be mounted with the connector pointing down and the elements horizontal. If mounting on a spar or bracket, the antenna elements must be oriented approximately 45° to the horizontal support when looking from the top or bottom, as shown in Figure 12. Use one of the following methods to mount the antenna per the guidelines and general information above with all four elements in the horizontal plane: · · · The included mount can be used to attach to any small, flat, horizontal surface; i. e. In this case drill holes in the pattern of the mount and attach with marine grade screws as needed (not supplied). The included mount can be used to attach the antenna to a round spar using U-bolts. [. . . ] This speeds up the reaction time by not having to wait for one of the LEOSAR satellite to pass overhead. Because most of the search and rescue forces presently are not equipped to home in on the 406 MHz Satellite beacons signal, homing must be accomplished at 121. 5 MHz. 6. 3 Global Positioning System (GPS) The GPS system is a satellite group that enables a GPS receiver to determine its exact position to within 30m anywhere on Earth. With a minimum of 24 GPS satellites orbiting the Earth at an altitude of approximately 11, 000 miles they provide users with accurate information on position, velocity, and time anywhere in the world and in all weather conditions.
