APPENDIX 2 - Euroleague Basketball

The 24-second clock must be automatic, with a digital
countdown to indicate the time in full seconds only and a very
powerful acoustic signal to indicate the end of the 24-second
period.
The colour of the numbers of the 24-second clock and the
numbers of the additional game clock will be different. It is
recommended that the 24-second clock numbers be red and the
additional game clock numbers yellow. The numbers of the
display units will have a minimum height of 25cm and a
minimum width of 12.5cm.
There will be backup 24-second clocks that can be placed
directly on two corners, just off the playing court, in the event of
a permanent malfunction of the main 24-second clocks.
Therefore, backup wiring for the 24-second clocks will be placed
at these locations.
46.3. Whistle-Controlled Time System
A whistle-controlled time system will be used in all games. All
the arenas must have the necessary equipment approved by the
Company, composed of one device and four belt packs. One of
them will be a backup belt pack. This equipment will be duly
connected to the main game clock and work properly.
46.4. Acoustic Signals
Two separate acoustic signals are required with different, very
powerful sounds:
One for the scorer and timer. For the scorer it will be
activated manually. For the timer it will sound
automatically at the end of playing time for a period, extra
period and/or game.
One for the 24-second operator, which will sound
automatically at the end of the 24-second period.
These two signals must be sufficiently powerful so as to be
heard easily in noisy conditions. A connection to the public
address system of the arena is recommended. The Company will
request the club to make the acoustic signals louder when it
considers that they cannot be easily heard.
46.5. Table Officials Equipment
In addition to what is indicated previously, the arena must have
100
