Modes of Operation

Sign Display

The Sign Display can be set to a desired speed, say 45 kmh. If a vehicle’s speed is 40 kmh the speed will not be displayed, therefore saving power.

Over Speed Flashing

The Sign Display will flash when a motorist exceeds this setting. For example, if the Over Speed Flashing is set to 50 kmh, if a motorist is driving at 55 kmh, the display will flash the speed of the vehicle indicating that the driver is speeding.

Extreme Speed

The main purpose of the Speed Director is to prevent people from speeding. The Extreme Speed will not display the speed of the motorist instead it will flash Corner Caution. This mode is designed to discourage motorists from driving even faster to see what the maximum speed of the Speed Director is.

Power & Battery Charger

The Speed Director is powered from 2 x 6v 225 Ah capacity deep cycle batteries. The Speed Director is fitted with a 15-amp caravan plug for battery recharging using the on-board battery charger. The battery charger (25 AMP) has a 12 hour charge cycle and features an automatic shut-off facility. The display can operate for approx. 2 weeks (24 hours per day) on a fully charged battery set.

Data Collection

The Speed Director is able to record the speeds that motorists have been detected at. The data is recorded in a chart format, which shows the number of vehicles detected, the time they were detected, and also the speed in either instant recording format or 1,5,30 or 60 minute averaging format. A print out of this data is available in a report or can be exported into Microsoft Excel where graphs or charts can be produced if required.
