Designed for Commercial Fleet Vehicles

The ALCOLOCK V3 LE is the latest evolution of alcohol interlocks for commercial fleet vehicles

to meet the low energy requirements of automotive design engineers.

What is an alcohol interlock?

An alcohol interlock is a device that prevents a vehicle from starting if the driver has a breath alcohol concentration (BrAC) over a preset limit. The alcohol interlock consists of a handheld breath alcohol tester and an electrical control unit (ECU) that is connected to the starting mechanism of any vehicle.

Low Energy

This new series offers a low quiescent (sleep) current of less than 1 mA to meet the latest automotive power network requirements.

Programmable

Drivers may be tested at the beginning of their shift or at intervals throughout the day. The ALCOLOCK V3 LE system can be programmed to meet company safety policy requirements. Proprietary software allows reporting and logging of breath test results, times, dates and more.
