Choose an alcohol ignition interlock system for your coaches

Current regulations require the use of alcohol ignition interlock devices in all vehicles used for public transport. The AIS models designed for these vehicles differ in their operation from those installed in the context of a judicial or prefectural decision.

We offer you a UTAC and CENELEC 50436-2 approved AIS that complies precisely with the regulations concerning the use of breathalysers.

UTAC approved, Vignal Sesaly's Autowatch AIS is the first alcohol ignition interlock system that can remotely download data via radio frequency. Its system allows to control the correct use of the AIS without having to move in the vehicle: the recorded data are stored in the VBS located in the vehicle (and not in the analyzer as for most models).

Placed in the vehicle, the VBS sends the data to the PC via a USB key to be inserted in the computer connected to your network or local computer. This essential data control makes our AIS a particularly practical and efficient piece of equipment.
