The DC-802T Down Basketball Game Competition Timer is a fully integrated scoring and countdown system designed for competitive basketball challenges in both indoor and outdoor environments. Built around precision sensing and simplified wiring, this custom system combines a two-digit, 8-inch counter mounted on top with a two-digit countdown timer positioned below. The entire unit is controlled from a wired start switch that activates the timed competition period and scoring sequence in one streamlined process.

Once the start switch is pressed, the preset 30-second timer begins its countdown. During this period, the counter is activated and the system allows the electric sensor to detect made baskets. When time expires, the timer flashes to clearly indicate the end of the period. Any shots made after expiration will not register, ensuring fair and accurate competition play.

This system is operated directly from the timer housing. The wiring layout is intentionally straightforward, with color-matched connections for quick and reliable installation:

• Start switch wires connect directly to the timer, with matching wire colors for simple setup
• Counter activation and deactivation are controlled through the timer
• Green and white wires handle the scoring trigger connection
• Sensor wiring includes three leads:
  • Brown for power
  • Blue for negative
  • Black for trigger
• All wire colors match accordingly to minimize installation confusion

The electric sensor features a blue beam detection system and is mounted directly underneath the basketball rim using a durable bracket. The recommended mounting position is centered beneath the rim, aligned to detect the ball as it passes cleanly through the middle. The sensor includes both visual indicators and adjustable sensitivity to ensure accurate operation.

Sensor functionality and adjustments include:

• Blue LED indicator confirms power and beam visibility
• Orange LED illuminates when the sensor is triggered
• Adjustable sensitivity using a slotted potentiometer on top of the unit
• Rotational adjustment up or down for fine-tuning detection angle
• Twist-lock rear connector for secure cable attachment
• Compatible with official 16-inch rims and tested successfully on 15-inch rims

When a basketball passes through the rim, the blue beam reflects off the ball and returns to the sensor, triggering the counter. The system is calibrated to detect a properly sized basketball—such as a number six ball, NBA-style ball, or college-style ball—while preventing false triggers from net movement. The beam is set to detect in the center of the rim rather than the front edge to ensure accurate scoring. For best performance, trimming or removing excess net strand support is recommended to allow a clear beam path through the net.

Installation can be configured for indoor gymnasiums or outdoor courts. The sensor bracket mounts securely beneath the rim using two screws, and wiring can be routed cleanly through a drilled access hole in the backboard. The junction box mounted with the 8-inch counter provides protected wiring connections and organized cable management.

During operation, players press the start switch to initiate the countdown. As baskets are made within the 30-second window, the counter increases accordingly. The visual flashing at the end of the period provides a clear, unmistakable signal that time has expired and scoring has stopped.

The DC-802T Down Basketball Game Competition Timer is ideal for:

• Timed shooting competitions
• Training drills
• Fundraising challenge events
• School and recreation center contests
• Outdoor tournament setups

With adjustable sensitivity, clear LED diagnostics, color-coded wiring, and a durable mounting system, the DC-802T provides a reliable, competition-ready basketball timing and scoring solution designed for straightforward installation and consistent performance.
