The guidelines used by AMS to confirm an Alcohol Detected alert include:
• Presence of an absorption curve
• Presence of a burn-off curve
• Obstruction in place of the absorption curve
Figure 6: Alcohol Detected
As stated earlier, an Alcohol Detected alert can also be generated by the introduction of
an interferant. The following graph illustrates the alcohol absorption and burn-off curve
caused by an interferant, and how the difference is detected and confirmed.

What is a Potential Tamper alert?
A Potential Tamper alert is an indication that the client has inserted something under the
SCRAM Bracelet in order to inhibit the testing of alcohol. This alert is generated when
there is an unacceptable change in IR voltage from the previous reading. A slight change
in the IR voltage can be caused from the following:
• Obstruction- A material being placed between the bracelet and leg
• Submersion- Submerging the bracelet in water
