Electronic Speed Limit Signs (ESLS)

DeNeefe Electronic Speed Limit Sign (ESLS) offers a high visibly, programmable speed display for use in a variable speed zone. The sign uses high intensity white LED display, red annulus and optional yellow conspicuity device. Utilising the latest electronic hardware and software technology, the sign displays bright, clear and concise speed limits as per AS1743, variable at user’s preference.

The sign has been designed as per AS5156-2010. It is designed to communicate via the most commonly used RTA protocol on the existing road.

Activated Warning Signs

DeNeefe Activated Warning Signs are mounted on a pole with a solar panel and control box, housing the solar battery, charger and sign controller.

Truck Entry Warning Sign

For installations where the sign is not within line of sight with the approaching vehicle, the radar detector can be mounted on a separate pole, with its own solar panel and battery, with either a radio or hard wire link used to communicate with the sign(s). More than one sign can be connected to the radio or hard wired link, to operate off the remote radar detector.

The solar cell and battery can be operated for at least 2 hours per day with solar charging, and up to 2 weeks on a full battery charge.

Ice and Snow Warning Sign

The Ice/Snow Warning Sign is mounted on a pole with a solar panel and control box housing the solar battery, charger and sign controller. The sign has an optional radar detector, for detecting the approaching traffic at a maximum distance of 140m and a minimum speed of 10kph, allowing the sign to conserve power by only flashing in the presence of approaching traffic.

A temperature sensor probe typically installed into the road surface for monitoring ice and snow conditions, may be prone to damage, or mechanical failure due to road resurfacing. Alternately, an optional remote infrared sensor can be installed on the sign for monitoring the road surface temperature, which would not be prone to mechanical failure.

The solar cell and battery can be sized to operate for at least 2 hours of solar charging per day and up to 2 weeks on a fully charge battery without charging.

  • Minimum speed 10km/hr
  • Max Range 140m
  • Can reduce power by flashing only on approaching traffic
  • Radar Detector (Option)
  • Infrared road surface temperature sensor (Option)
