Transponder
The L-3 ProTec is a single box design which is easily installed into any existing
bridge layout. The compact design requires minimal clearance (refer to Section 4
Figure 4–1 and Figure 4–2) and can be mounted in a trunion bracket or mounted
flush using the available flush–mount bracket.

F
Mount the transponder in a position which provides easy access to the key-
board and display.
F
If using the trunion bracket, the mount itself may be used to mark the screw
holes on the mounting surface. When locating the transponder, consider that
the IMO mandates that the AIS keyboard and display be easily accessed from
a navigable position on the bridge.
F
If used, Mount the transponder in the trunion utilizing the trunion knobs pro-
vided, otherwise mount transponder in flush mount bracket.
F
Locate and mount the terminal block or junction box in a position near the
transponder. The IEC cable provided with the unit is 100 inches (2.54 m) long.
Locate the terminal block in a fashion which allows for easy access to the termi-
nals for making the connections to required input/output feeds.
F
When connecting the power cable, the “Red“ lead goes to positive and “Black“
to negative. Ensure proper ground wire attachment to ships structure. The oth-
er two leads can be used to connect to an external alarm system. This alarm
system can provide an audio and/or visual alarm in the event of an internal sys-
tem malfunction, or if the AIS loses power or is turned off.
Install the transponder, and complete the AIS Installation Checklist found it Ap-
