Alcolock™ V3

Superior Alcohol Interlock Technology

The ALCOLOCK™ V3 alcohol interlock measures the breath-alcohol concentration (BrAC) of a driver, and prevents the vehicle from starting if the driver’s BrAC is over a preset limit.

Its durable construction ensures reliability in a range of vehicles and equipment, such as trucks, ships and heavy machinery. The Alcolock V3 is engineered to withstand vibration, dirt, dust, humidity and extreme temperatures typically found in commercial applications.

Easy breath sampling

Drivers simply blow into the handset and, within seconds, the Alcolock V3 analyses the breath sample and displays instructions to the driver. Optional sensors help ensure mechanical devices such as air pumps cannot be used to circumvent the system.

Emergency override

Alcolock V3 includes an electronic override for emergency situations. Override activation is evident to employers if an employee attempts to circumvent the system.

Programmable to suit your business

Drivers can be tested at the beginning of their shift or throughout the day, by programming the Alcolock V3 to meet your company’s safety policy. Optional software allows valuable reporting of logged events such as breath test results, times, dates and more. Event logs can be accessed from a central server or downloaded locally to a personal computer.
