1.0 ALCOLOCK LR MAX ALCOHOL INTERLOCK PRODUCT
PROFILE
The ALCOLOCK LR max alcohol interlock controls the normal operation of a
vehicle through connection with the power, starter and control systems. To start
the vehicle engine, the driver must provide an accepted breath test with a breath
alcohol concentration (BrAC) below the preset limit. During operation of the
vehicle, the driver will be requested to provide additional breath tests to maintain
compliance with program requirements. The ALCOLOCK LR max device will
never cause the vehicle engine to stop.
The ALCOLOCK LR max device consists of a Handset (HS) to conduct breath
alcohol tests, and an Electronic Control Unit (ECU) that is connected with
the power and control circuits of the vehicle. The ALCOLOCK LR max device
includes a GPS/GPRS patch antenna–connected separately–for the real-time
transfer of critical log events.
The ALCOLOCK LR max device is used in alcohol interlock programs under the
direction of a jurisdictional authority and conforms to international regulations for
alcohol interlocks being used in compliance programs.
