The Dräger Interlock XT is an breathalyzer with automatic vehicle starter interlock.
The driver must perform a sobriety test before starting the vehicle. If the alcohol concentration exceeds a pre-set limit, the starter is blocked and the car is not allowed to start. Additional tests at random intervals may be required to ensure that the vehicle continues to be driven by a sober person. E.g. the driver must perform an additional blowing after 10 minutes, after which the test is required to be performed at least once an hour at a random time unknown to the driver in advance (all intervals are configurable). When alcohol is detected, the system does not turn off the car's ignition, but it stores the fault in memory and can perform additional actions, e.g. the vehicle's hazard warning lights, audible signal or other equipment connected to the Dräger Interlock XT relay are activated. The device records all information (successful and unsuccessful attempts to start, start the engine without the sobriety test, attempt to disconnect the breathalyzer or battery, all other operations with the device) in a memory that can be viewed later. Drivers with alcohol problems, manipulation, or alcohol disconnection / bypassing may be identified during a memory review. |
