Dräger Interlock® 7000

The Dräger Interlock® 7000 is an alcohol ignition interlock device (AIID) which prevents a person under the influence of alcohol from starting the vehicle. The Interlock® 7000 has a quick start-up time. Additionally, the device can be equipped with a camera, a GPS and/or a mobile data transfer module, according to the specific customer requirements.

Reliable prevention of driving under the influence of alcohol

An Interlock 7000 is a car breathalyzer, which can be used preventively in public transportation, freight transport and at workplace to reduce the risk of drink-driving. The Interlock 7000 is also used in many countries for legal measures, as part of the “drink-driving offender programs (DUI/DWI)”. In these countries, offenders who were caught with a blood alcohol level over a certain limit have to use an Interlock device in their cars. Reliable results, tamper-proof data recording and data management play a key role in these programs.

Interlock 7000 FAQ's

How the Interlock 7000 works

The Interlock 7000 consists of two components: handset and control unit. In the handset the breath sample is analysed. The control unit releases or blocks the starter relay of the vehicle. Once the vehicle’s ignition is switched on, the Interlock 7000 requests a breath test from the driver. If the device detects an alcohol value (BrAC) above the set limit, it prevents the engine from being started. The device helps to systematically eliminate alcohol-related risks of accidents and to prevent impaired driving.

Quick operational readiness

Particular features of the Interlock 7000 are the extremely short warm-up and its quick readiness for use. At temperatures of more than 0 °C it is ready for immediate use. At temperatures below 0 °C the ignition interlock is still quickly ready for use. With an approved temperature range of -40 °C to 85 °C, it ensures that the device works reliably under all kinds of ambient conditions.

Easy operation of the alcohol interlock

The design of the Interlock 7000 is appealing and ergonomic, with the mouthpiece on the back of the handset – hence, not easily recognised as an alcohol ignition interlock device. The hygienic mouthpieces of the Interlock 7000 are completely biodegradable. The breath sample can be given in no time. The navigation on the colour display makes the use of this device easy and intuitive. Additionally, coloured LEDs on the device enhance the ease of use for the user.

Safe data handling

The data log of the Interlock 7000 saves all relevant events such as date, time, submission or refusal to submit an alcohol test, measured alcohol concentration, engine starts and stops and any attempts to tamper with the interlock device. The data is transferred from the control unit to the PC via an infrared interface. Downloaded data is available to authorised persons only. From creation to provision of the data special encryption methods guarantee data protection.

Mobile data transfer module

If the Interlock 7000 is equipped with an additional mobile data transfer module, it is possible for certain predefined events to transmit data automatically to the responsible entity or person via a cellular network. This event can, for example, be an attempt to start the engine under the influence of alcohol.


The Dräger Interlock 7000 can be equipped with a camera for applications where it is a legal requirement or for special customer requirements. The camera records the submitted breath samples with images. It can be easily installed in each vehicle. The infrared technology ensures good image quality, regardless of whether it is day or night.

Reliable measurement technology

The Interlock 7000 specifically measures alcohol. The measuring result is reliable and precise. Also, attempts to bypass or manipulate the device are reliably identified and stored in the system. The device is able to identify whether the alcohol detected in the breath sample is actual breath alcohol or only mouth alcohol.

Proven Dräger technology
