The cost of outdoor message centers has dropped significantly in recent
years, and at the same time, the quality, visibility, and performance
have dramatically improved. Today's signs require almost no maintenance
and no annual bulb replacement material or labor charges, since there
are no light bulbs to change.
Today's signs require less than 10% of
the power (electric consumption) than incandescent signs, and they generate
considerably less heat. Since today's signs are advanced solid state
design, when they do require service, they are easier to service.
Programmable signs that are used outdoors are made quite differently
from signs that are used indoors.
- Outdoor signs are made in weatherproof NEMA outdoor enclosures that
are designed to protect the sign electronics from the elements.
- Outdoor signs use brighter lamps -- LEDs for outdoor use must be
bright enough to be seen in bright sunlight. Where indoor LED's are
rated at 20 millicandela per pixel, outdoor LEDs range from 1,200
millicandela to 15,000 millicandela per pixel or more.
- Outdoor LED signs usually have multiple super-bright LED's (from
2 to 25 or more) in each pixel to achieve a brightness of as much
as 15,000 millicandela per pixel, so that the sign can be read easily
in daylight. Clustering LED's in a pixel also makes the characters
- The LED's in outdoor signs are made to withstand UV exposure. The
LED's do not turn dark over time.
- Mounting brackets are provided.
LED Programmable Message Centers will display from one to thirteen
lines of text at a time, depending on the model.
signs serve a broad range of sign applications under most weather
long-life LEDs translate into low maintenance and low energy compared
to the high maintenance cost and high operating cost associated
with incandescent models.
Message Centers will display characters ranging from 2" to
17'' in height in a variety of fonts.
top, bottom and sides of the enclosures are aluminum extrusions,
coated black. The face is red or amber polycarbonate, weather-resistant
and is removable from the front for service.
models may be programmed to display the current time and current
models contain from 1 MB of computer memory in which messages are
stored and run automatically.
Message Centers are programmed from any Window-compatible computer.
- A variety
of Connectivity Options are available. Messages may be sent to the
sign via RS232 or RS485 cable, via modem, via wireless devices,
via ethernet devices, or using a Serial Message Loader.
maximum length of a cable without a repeater is 4,000 feet. Cabling
can configured in both daisy-chain and point-to-point cable configurations
simultaneously. All models have RS232 and RS485 connectivity. .
- Messages may contain text, graphics, and animations.
- You may set the either the message or the background to display in black or the LED color (red or amber).
- Messages may be scheduled to run at specific times on specific days and specific time intervals.
