What is an alcohol interlock?
The G series handset can have a wired or wireless connection to the
ECU, depending on its version.
To help prevent other people from providing the required breath
samples, the interlock requests additional breath samples at random
intervals during the trip.
How does it work?
The G Series uses the same alcohol sensing technology used by police
in roadside screening. A special alcohol-sensitive cell detects the
amount of alcohol in the breath. Breath alcohol is directly
proportional to the blood alcohol concentration (BAC).

An Alcohol Interlock is an in-car breath alcohol
screening instrument. It prevents a vehicle from
starting if it detects that a driver's breath alcohol
concentration (BrAC) is over a preset limit. It is
designed to fit inside the vehicle, near the driver's
seat, and connects directly to the vehicle's ignition
system.n
The interlock consists of a handset and an Electronic
Control Unit (ECU). The ECU enables and disables
the ignition of the motor and stores the handset
settings.
