Requests breath sample, enables ignition

Prior to starting the engine, the Interlock 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.

All events recorded in a data memory

The data memory records more than 30,000 events and can be read via special PC software.

High measurement accuracy

The  Interlock determines the breath alcohol concentration via an electro-chemical sensor system. The device is responsive to alcohol only.
