The following section describes the 120 VAC trumpet horn installation for an LED scoreboard.
Assemblies are only available for 120 VAC scoreboards.
Note: Disconnect power to the scoreboard before installing the horn!
3.1 Equipment
The trumpet horn kit consists of:
 a horn
 a metal mounting angle
 a horn interface card and harness
 assorted #10 screws, tapping screws, and nuts
3.2 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.
3.3 Basic Horn Installation
 If the horn kit was ordered with the scoreboard, the horn interface card, mounting angle,
and horn body were likely installed at the factory; follow the simple instructions below.
 If these components have not been installed, skip ahead to Section 3.4.
1. Locate the horn entrance panel (see Section 3.2).
