Temperature protection
The AlphaPremiere™ 9000 sign includes automatic temperature controls to determine when the internal
temperature of the sign is too hot to continue normal operation. While the temperature controls are based
primarily on the internal temperature of the sign, they are also affected by both ambient temperature and the
sign’s load and its duration. So the higher the ambient temperature and the more LEDs that are on and the longer
they are on, the higher the internal temperature.
Trigger temperature levels may vary from sign to sign, but in general the functioning is:
• As the temperature of the sign rises, cooling fans are switched on. If the temperature falls below the
cooling fan threshold level, the cooling fans are turned off.
• If, however, the temperature of the sign continues to rise, auto-dimming occurs. This means that the
LED output from the sign is forced into a reduced power mode, effectively dimming the brightness of
the LEDs. If the temperature falls below the auto-dimming threshold level, then auto-dimming stops
and the LED brightness returns to normal level.
EMI compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with installation guidelines, may cause harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful interference, in which case the user will be required
to correct the interference at his own expense.
