The MUTCD compliant DF15 unit employs FCC compliant microwave Doppler radar to detect vehicle approach speeds.

Targeted drivers are informed of their speed with a 15inch character high intensity LED display and by using a configuration program the DF15 can escalate the warning provided in direct relation to the speed it detects.

Df15 incorporates unique flashing beacon pairs top and bottom of warning message to clearly indicate speed violation while keeping main display solid and easy to read.

The DF15 is the first driver feedback sign to provide potential road condition feedback with its automated Slow Ice warning message. Adjusting driver speed and behaviour to suit road conditions is key to reducing accident rates.

The DF15 driver feedback sign series are to be used in tandem with existing static regulatory signage being deployed downstream as a targeted reminder and are not to be used as a replacement for the static signage.

DF15 Control Panel

Activation Speed is the value at which if exceeded will trigger the sign to display a steady indication of the vehicle’s approach speed.

Notification Speed is a higher value which if exceeded would cause the speed to be shown accompanied by the flashing beacons. If the beacons are disabled using the Options Tab the display will flash the vehicle approach speed at the driver.

Slow Down Speed is the next speed increment and above this value the display will alternate between the approach speed and the SLOW DOWN legend. Also, if the beacons are enabled they will flash.

DF15 Control Panel

Max Speed setting will disable the speed feedback to the driver to prevent the sign being used for ‘highest score’ competitions. However the Slow Down legend and beacons (where enabled) will still flash.

Note: Any Combinations of settings can be employed:

The combination opposite right would cause the sign to feedback a steady display of approach speed from 30 , until 45 when the speed read out would cease. The Slow Down legend and beacons (where enabled) will still flash.
