Alpha Eclipse 1500 Time and Temperature LED Sign Models

Technical Support


  • The Alpha Eclipse 1500 is an single-color electronic LED outdoor sign that can display the time and the temperature in Fahrenheit and/or Centigrade.
  • The Alpha Eclipse 1500 is one of the brightest and sharpest outdoor time and temperature displays available.
  • Two Alpha Eclipse 1500 signs can be connected together and synchronized.
  • An optical sensor enables the LEDs to automatically dim at dusk and automatically brighten at dawn. The user may specify the dimming percentage.
  • The display font is selectable.
  • The user may specify the hold time for each display screen.
  • In the event of a power loss, a backup battery in the Alpha Eclipse 1500 provides short-term power to retain the time, dimming percentage, and hold time settings.
  • Super-bright, daylight-visible LEDs provide over 100,000 hours of continuous operation, significantly outlasting comparable incandescent lamps.
  • Alpha Eclipse 1500 displays consume less than 1/40th the power of incandescent Time and Temperature displays, providing significant savings in electricity costs.
  • The Alpha Eclipse 1500 has a weather-resistant enclosure.
  • Each sign face is front-serviceable.
  • A back-to-back model consists of two signs connected together by communications wire.
  • The Alpha Eclipse 1500 display is energy-efficient and easy to operate, install and service.
  • A limited five-year warranty is provided


Alpha Eclipse 1500 Time and Temperature LED Sign is designed for industrial and commercial use.

The Alpha Eclipse 1500 Time and Temperature LED Sign is designed for high-visibility, high-traffic applications.

The Alpha Eclipse 1500 Time and Temperature LED Sign is the perfect attention-grabbing solution for businesses where message centers are not permitted or where the cost of a message center is prohibitive.

Attract attention with an eye-catching Time and Temperature display to dramatically increase your company sales and profits.


A palm-sized Remote Control device (cabled) is used to set the time, to specify the hold time for each screen, to set the dimming percentage, and to specify which functions to display: 12- or 24-hour time, Fahrenheit temperature, and/or Centigrade temperature. A computer is not required.


Each Alpha Eclipse 1500 sign has two horizontal angle irons across the back of the sign. One is even with the top and one is even with the bottom. Provide a matching pair of angle irons on your wall, pole, or monument, and installation is very simple.

If the sign is mounted to a solid surface like a wall, nothing should block the space between the top, bottom, and sides of the sign and the solid surface.

If there is an obstruction, as in a monument-style installation, then run duct work (not supplied) from the bottom of each fan cover to the side edge of the sign. Do not run duct work to the top of the sign, since rain or other material could enter the sign. Do not run the duct work to the bottom of the sign, since this could force exhaust air back into the sign.

Electrical Guidelines

  • Run power wiring from a switched, fused power source.
  • Install a two-pole disconnect device in the building wiring for each branch circuit supplying the sign.
  • Run separate conduits to the sign for power and communication connections.
  • Make all electrical connections watertight.
  • Make sure the sign is properly earth grounded. The sign's support structure should not be used as ground.
  • Use minimum 80???C copper wire only. Torque terminals to 7-10 inch/pounds.

The Alpha Eclipse 1500 Time and Temperature Displays are available with 120V or 240V AC power.

The Alpha Eclipse 1500 does not ship with a power cord.

Your electrician must provide conduit, connectors and wiring to properly connect and seal the electrical connections inside and outside the sign and the junction box (not included).

Temperature Protection

The Alpha Eclipse 1500 will start and operate at temperatures from -40 to 131F (-40 to 5C).

The sign is protected from extreme temperatures by heaters and cooling fans. These are activated by the internal temperature of the sign, not the external temperature.

  • At or below 4C (40F), an internal heater strip will automatically turn on. Air warmed by the heater strip will be blown by a fan throughout the enclosure. If the temperature rises to or above 16C (60F), the internal heaters will turn off.
  • At or above 29C (15ºF), a cooling fan will automatically turn on. If he temperature drops to 19C (67F), then the cooling fans will turn off. At or above 70C (15F), over-temperature dimming will occur. The LED output of the sign will automatically be reduced to 50% of its maximum output. If the temperature falls to 68C (154F) then over-temperature dimming will stop.

Alpha Eclipse 1500 Time and Temp Features

  • Multiple Connectivity Options – Two Alpha Eclipse 1500 units may be connected together in a Master-Slave configuration. The twi signs must be within 25 feet of each other..
  • Dimming Feature – The brightness of the LEDs may be dimmed by a built-in optical sensor. You may specify the percentage of brightness to be dimmed. The dimming feature can be disabled, if necessary..
  • Overheating Protection - Automatic internal controls determine when the internal temperature of the sign is too hot to continue normal operation. Ambient external temperature and heat generated by the LEDs affect the internal temperature. As the temperature inside the sign rises, cooling fans are switched on. When the temperature falls below the cooling fan threshold, the fans turn off. If the temperature continues to rise, auto-dimming occurs, and the display goes into a reduced power mode, dimming the brightness of the LEDs until the temperature falls below the auto-dimming threshold level. For adequate ventilation, allow at least 1 inch clearance all around the sign.
  • DIP Switches - DIP switches located on the controller board inside the sign can be used to set:
    • Time Mode - 12 or 24 Hour
    • Length of Hold Time
    • Dimming Percentage
    • Any Combination of Time and Temperature
    • Temperature in Fahrenheit
    • Temperature in Centigrade

  • Mounting Hardware – Each Alpha Eclipse 1500 Time and Temperature LED Sign includes mounting hardware for wall or pole mounting. Fasteners to attach the sign to a ceiling, wall, or counter are not supplied; however, additional mounting hardware for wall mount or pole mount applications is available as an extra charge option. The specific type of fastener required will vary depending on the physical characteristics of the material (drywall, concrete, brick, wood, etc.). Each of the fasteners that you use must be capable of supporting four (4) times the weight of the sign. An overhead support, wall or counter should also be capable of supporting four times the weight of the sign.
  • Five-Year Warranty – The Alpha Eclipse 1500 Time and Temperature LED Sign has a five-year USA factory warranty. After the warranty expires, the Alpha Eclipse 1500 Time and Temperature LED Sign components will be repaired and returned for time and materials charges.
