What is a Potential Removal alert?
The Potential Removal alert indicates the client has cut the strap or removed the bracelet
without damaging the strap.
What is the IR sensor?
IR is an abbreviation for Infrared. The IR sensor measures the reflective intensity of an
IR beam between the bracelet and the client’s leg. This component is used to ensure that
the bracelet is on the client and to detect materials being placed between the bracelet and
the leg, potentially blocking the alcohol sensors of the faceplate. If there is an
unacceptable change in the IR reading from one reading to the next, a Potential Tamper
alert is generated.
What is the initial IR reading?
The first IR reading that is taken when the SCRAM Bracelet is installed on the client.
What is the baseline voltage?
The acceptable range for IR variance based on the initial IR reading. A variance of +/- 0
to 0.25 volts is expected.
What is an observed IR reading?
AMS may request that the client come into your office for an observed IR reading. The
client must bring their modem into the office for the appointment. The client’s bracelet
will be inspected for any sign of damage and inspected to confirm that nothing is between
the bracelet and the leg. The client’s modem is plugged in and the bracelet is forced to
take a reading under supervision. Forcing the bracelet to take a reading while the client is
in the office ensures the client understands what is expected of their IR voltage pattern. If
a non-compliant voltage pattern is observed, the client will be asked to come into the
office for an observed IR reading to highlight the periods of non-compliance.
What is a Confirmed Obstruction?
AMS will confirm an obstruction when there is a change in IR voltage for an extended
period of time. If the faceplate of the bracelet (IR sensor) is blocked for several hours, a
client could drink to a .04% level, burn it off and the SCRAM System would not detect
the event. A confirmed obstruction indicates that the client has attempted to defeat the
technology and has compromised alcohol testing.
Potential Removal
A Potential Removal alert is generated under the following circumstances:
• The vast majority of Potential Removal alerts are generated when Service
Provider personnel are replacing the bracelet battery. However, if an authorized
battery replacement was not conducted on the day that the alert was generated,
the client has probably removed the bracelet.
• The strap has been damaged or cut in an attempt to remove the bracelet.
