Alcohol Interlock
Technical Specifications
12/24 Volt Model

Overview

The ALCOLOCK series of alcohol interlocks are devices which are intended to prevent
in the blocked state the starting of a motor vehicle, and which can be brought into the
unblocked state only after presenting and analyzing a breath sample with an alcohol
concentration below a set value. It consists of a handset and a control unit electrically
connected to the vehicle.

The ALCOLOCK alcohol interlock only prevents the starting of the vehicle; it does not
influence a running vehicle motor.

The installation of the ALCOLOCK alcohol interlock requires connection to vehicle +12V
or +24V, vehicle ground, monitoring of either the ignition switch or tachometer signal or
both, and the interruption of the starter wire.

After presenting a proper breath sample the ALCOLOCK alcohol interlock will close a
set of relay contacts that allow the vehicle motor to start. The ALCOLOCK alcohol
interlock starter relay shall stay closed until after the vehicle motor and ignition switch
has been turned off plus a preprogrammed restart period. The restart period does not
require a new breath sample and is typically programmed between 3 and 60 minutes.

This version of the ALCOLOCK LR alcohol interlock includes a GPS module that logs
the coordinates of the vehicle where the device is mounted.
