How Our Device Works for the Deaf and Hearing Impaired

The Dräger Interlock 7000 devices display a combination of easy-to-understand written prompts along with color-coded visual indicators during use.

For example:

• • When you start the ignition interlock, the device will display “Ready for Test – Please Blow”, after a few seconds warm-up time.  A blue indicator light at the top of the device will flash repeatedly to grab your attention, letting you know it’s ready for action.
  • As you blow, the light will turn off, letting you know that you’re blowing correctly. Don’t stop blowing when the light turns off!
  • When you pass a test, the color display will show “Test Passed” along with a large green checkmark.  Additionally, a bright green indicator light on top of the device lets you know that you’re ready to start the vehicle.
  • If the Interlock 7000 detects alcohol on your breath or any issue with the sample provided, the color display will show a red X and written indication such as “Test Failed” or “Blow longer, repeat test” to let you know what went wrong.  A red indicator light on top of the device also shows that a passing sample was not provided. The vehicle will not start until a passing sample is provided.
  • Once you’re driving and the device is ready for a required retest, it will once again flash the blue indicator light on top of the device and indicate “Ready for Test, Please Blow”.

In addition to the color-coded visual indicators on the device itself, an optional auxiliary LED light can be installed anywhere on the dashboard.  This auxiliary light will flash anytime a test is requested by the device, serving as an additional visual notification to the driver that action is required.
