1. Locate the horn entrance panel (see Section 3.2). There should be a 2" knockout on
this panel. Remove this knockout. If the knockout has not been provided, use
Drawing A-83502 as a guide to drill one 2" hole in the panel.
Note 1: Be careful not to damage any internal components when drilling!
Note 2: The knockout may have been removed at the factory.
2. Remove the trumpet from the horn body by unscrewing it.
3. Mount the bracket to the scoreboard frame using #10 hardware provided, and
connect the horn harness to the horn wires with included wire nuts. Refer to
Drawing A-308058. For newer “P1647” scoreboards, refer to Drawing A-1055044.
For the TI-2003, refer to Drawing B-172553.
Note: When replacing a horn:
1) Use
1 /
4
" bolts, nuts, and lock washers provided to attach the horn body to the
mounting bracket so that the horn is on the same side as the short flange (the
horn should be pointing downward).
2) Be sure to mount the horn to the bracket so that the wires are facing the bottom
of the cabinet to prevent water from running along them.
3) Attach the copper ground lug to the bottom-right corner of the mounting bracket
using the bolt and serrated washer and nut provided, and connect the green wire
from the horn to the ground lug (does not apply to TI-2003).
4. Route the horn harness to A3-J3 on the horn interface card, per Drawing B-302328.
If the harness doesn’t reach, connect the 2-pin to 2-pin extension cable between the
horn and the horn interface card as needed.
5. Close the access panel and screw the trumpet back onto the horn body.
6. To test the horn, power on the scoreboard and control console, and press HORN.
