The SCRAM CAM bracelet rests against the leg, securing an electrochemical fuel cell sensor against the skin. It samples the "insensible perspiration" (vapor) that naturally migrates through the skin. This article provides an overview of SCRAM (Secure Continuous Remote Alcohol Monitor) usage in Tennessee, focusing on its application in DUI/DWI cases.
What is SCRAM?
SCRAM is a device used to continuously monitor an individual's alcohol consumption. It works by testing the wearer's perspiration for alcohol content. The device is typically worn on the ankle and is tamper-resistant. It's crucial to understand that the standard SCRAM CAM only monitors alcohol, not drugs like marijuana, cocaine, or opioids. Courts often pair SCRAM with random Urine Analysis (UA) to monitor for narcotics.
When is SCRAM Required in Tennessee DUI Cases?
While Tennessee law doesn't explicitly mandate SCRAM for all DUI convictions, its use is becoming increasingly common under certain circumstances:
- Bond Conditions: A magistrate judge reviewing a probable cause affidavit shortly after an arrest (usually within 24-48 hours) may order SCRAM if the affidavit indicates a prior conviction or a BAC (Blood Alcohol Content) higher than 0.15.
- Probation: If a defendant applies for probation and is assessed as "High Risk" for substance abuse through an evaluation similar to the Texas Risk Assessment System (TRAS), the probation officer will likely recommend SCRAM in the Pre-Sentence Investigation (PSI) report.
- Repeat Offenses: Similar to Texas, District Attorneys in Tennessee may have standard operating procedures requiring SCRAM as a condition of plea bargains for repeat DUI offenses (DUI 2nd, DUI 3rd, etc.).
- DWI Intervention and Specialty Courts: Following the model of Texas DWI Courts, Tennessee may utilize phased monitoring programs. Phase 1 (typically the first 3-6 months) often mandates SCRAM monitoring to establish a baseline of sobriety before stepping down to less intensive monitoring methods like portable breath units or random UAs.
How SCRAM Monitoring Works
The SCRAM CAM bracelet is attached to the ankle and takes readings every 30 minutes (48 times per day). The device utilizes several mechanisms for data collection and tamper detection:
- Transdermal Alcohol Monitoring: The bracelet samples insensible perspiration (vapor) that migrates through the skin. It has an electrochemical fuel cell sensor.
- Data Transmission: The bracelet typically communicates wirelessly with a base station in the home, uploading data to a central server. In areas with poor cell service, a traditional phone line or Ethernet cable might be necessary for the base station.
- Tamper Detection:
- An Infrared (IR) Voltage sensor measures the distance to the skin.
- A Temperature sensor detects if the device is no longer against warm body heat.
If remote transmission fails, the defendant must physically report to the provider's office to have the data downloaded via a USB cable.
SCRAM Costs in Tennessee
While specific costs in Tennessee can vary, the financial model is generally "offender-funded," similar to the "user-pay" model in Texas, placing a significant burden on defendants. Expect to pay for:
- Installation Fee: A one-time fee to set up the device.
- Daily/Monthly Monitoring Fee: A recurring fee for the monitoring service.
- Removal Fee: A fee to remove the device at the end of the monitoring period.
Vendors often require the installation fee plus the first two weeks of monitoring upfront before installing the device. Failure to keep up with daily fees results in the vendor notifying the court of "non-compliance."
Products to Avoid While on SCRAM
While on SCRAM, it's crucial to avoid products containing alcohol, even in small amounts. Examples include:
- Mouthwash: Use alcohol-free mouthwash.
- Non-alcoholic beer (O'Doul's): These contain trace amounts of alcohol (up to 0.5%) that can trigger a violation.
- Hand Sanitizer: Use carefully to avoid contact with the bracelet.
- Certain medications: Check with your doctor and the monitoring provider.
- Cooking with alcohol: Avoid cooking with wine or other alcoholic beverages.
What Triggers a SCRAM Violation?
Tennessee courts and probation departments recognize several types of violations:
- Confirmed Alcohol Consumption: Any reading of 0.020 BAC or higher will likely trigger an alert. To be confirmed, the data must show a specific absorption and elimination curve.
- Tamper/Obstruction: Placing anything (paper, foil, sock) between the sensor and skin to block the vapor will generate a tamper alert.
- Water Submersion: Prolonged submersion in water (bath, pool) is flagged.
- Equipment Damage (Strap Cut): Cutting or breaking the strap will result in a violation.
Even if mouthwash containing alcohol spills on the device, it can cause an environmental alert.
Consequences of a SCRAM Violation
A SCRAM violation can have serious consequences, including:
- Probation Revocation: If you're on probation, a violation could lead to jail time.
- Bond Revocation: If you're on bond, a violation could result in being taken back into custody.
- Increased Monitoring Period: The court may extend the length of time you're required to wear the SCRAM device.
Typical Monitoring Periods
The duration of SCRAM monitoring varies depending on the specifics of the case and court order. It can range from a few months to a year or longer. In DWI intervention programs, the initial phase typically lasts 3-6 months.
What to Do if the Battery Dies
This is considered a potential tamper. You are responsible for keeping the battery charged (if applicable) or reporting for battery changes. Data gaps caused by power loss are scrutinized suspiciously by courts.
MRI/X-Rays
You must notify your doctor and probation officer before getting an MRI or X-Ray. A temporary removal order from the judge is required. The device contains metal and electronics that are dangerous in an MRI machine.
For information about SCRAM monitoring services in your specific Tennessee county, it is best to contact your local probation office or the court that ordered the monitoring. You may also find information on the Tennessee Department of Correction's website.
What Is a SCRAM Bracelet?
SCRAM CAM (Continuous Alcohol Monitoring) is an ankle bracelet that tests your perspiration every 30 minutes to detect any alcohol consumption. Unlike breathalyzers that test at specific times, SCRAM provides 24/7 monitoring—you cannot "time" your drinking to avoid detection.
How It Works
- • Worn on ankle 24/7—cannot be removed
- • Tests perspiration (transdermal) for alcohol
- • Data uploaded via modem to monitoring center
- • Tamper-evident with obstruction detection
Detection Window
- • Tests every 30 minutes
- • Detects alcohol 2-12 hours after consumption
- • Even one drink will be detected
- • Cannot be fooled or circumvented
When Do Tennessee Courts Order SCRAM?
SCRAM monitoring is commonly ordered in these situations
Repeat DUI Offenders
Very CommonCourts commonly order SCRAM for second or subsequent DUI offenses to ensure no alcohol consumption during probation or pre-trial release.
High BAC Cases
CommonFirst-time DUI with high BAC (0.2+) may receive SCRAM monitoring to demonstrate sobriety.
Pre-Trial Release Condition
CommonAs an alternative to jail, judges may release defendants on bond with SCRAM monitoring to verify abstinence.
Probation Violation
Very CommonIf you violate probation terms (especially alcohol-related), SCRAM may be added as an enhanced monitoring condition.
Child Custody Cases
OccasionalFamily courts sometimes order SCRAM monitoring in custody disputes involving alcohol abuse allegations.
Voluntary Monitoring
OccasionalSome people choose SCRAM voluntarily to demonstrate sobriety to employers, family, or as part of rehabilitation.
SCRAM Providers in Tennessee
SCRAM monitoring is typically administered through probation departments or court-approved monitoring companies.
How to Get Set Up with SCRAM
Unlike ignition interlocks where you choose a provider, SCRAM monitoring is usually assigned by the court or probation department. Your monitoring provider will be specified in your court order.
SCRAM Systems (Primary)
