The following section describes the 12 VDC trumpet horn installation for an incandescent scoreboard.
Note: Disconnect power to the scoreboard before installing the horn!
4.1 Equipment
The trumpet horn kit consists of:
 a horn
 a metal mounting angle
 a metal enclosure and 12 volt power plate assembly
 assorted #10 screws, tapping screws, and nuts
4.2 Location
The horn entrance panel is typically located in the center of the lower half of the scoreboard
(refer to the component location drawings included in the scoreboard manual for specific
location). The horn will be mounted directly to this entrance panel. The panel may be secured
only by screws, or it may have hinges that allow it to swing open.

 If the horn kit was ordered with the scoreboard, the horn plate assembly was likely
installed at the factory; skip ahead to Section 4.4.
 If these components have not been installed, follow the instructions below.
