Requests breath sample, enables ignition
Prior to starting the engine, the Dräger Interlock XT requests a breath sample. If alcohol is detected above the state's legal limit, the
immobilizer system prevents the motor from starting. Otherwise, the
starter is activated for the driver to start the vehicle. The device
will also prompt the driver to retest periodically while en route. The
device will not disrupt the engine function once the engine has been
started, but the event will be recorded. Some states require the
horn to sound and / or the headlights to flash if a retest is failed.
To avoid long waiting periods, Dräger put emphasis on the Interlock XT being ready to use. Its functionality is as
good at -40 °F or +185 °F as it is in normal conditions. The name affix "XT"
stands for "eXtended Temperature".
All events recorded in a data memory
The data memory records more than 30,000 events and can be read via special PC software.
