TAIRS can provide equipment designed specifically to make the life of an Accident Investigator easier. It has been in use by Police Forces throughout the UK and is a tried and tested reliable product.

Chalk Guns
The most accurate method of determining the co-efficient of friction at a tyre/road interface is by skidding the accident vehicle whilst at the accident scene. The firing of most chalk gun devices relies upon pressure pads stuck on brake pedals, or fiddly wiring connections, either on the dashboard or around a rear brake light cluster.

The TAIRS system eliminates these fiddly connections with a system where a switched wiring loom is plugged into the brake light bulb socket. It allows for a wiring continuity test to establish that the device is working correctly. There is an additional switch position to abort a test if a run has been started and optimum conditions change.

The chalk gun itself is a simple readily available very low cost 'one shot' plastic device, used by most Police Forces (for other purposes) and is quickly but firmly attached to any vehicle by spring clips.

Tachograph Calibration Connections
If you are qualified to create a Tachograph Calibration Chart for Forensic use you will have experienced the problem of having 4 pin Lucas-Kienzle test equipment and a Volvo proximity unit fitted in the accident vehicle gearbox. Commonly, the time-consuming and occasionally destructive method of resolving this is the remove the head from the dashboard.

A TAIRS wiring loom with one end fitted with male/female Lucas-Kienzle 4 pin sockets and the other with the male/female connector of your choice, makes gearbox connections into a simple plug removal/replacement system.

Gearbox type pulse generators providing 2, 4, 6 or 8 pulses per revolution, in a 4 pin Lucas-Kienzle male socket format, can be provided.
