Alcohol Monitoring Device

About the SCRAM Program

SCRAM® (Secure Continuous Remote Alcohol Monitor) manufactured by Alcohol Monitoring Systems, Inc. (AMS) is a tool that helps courts and agencies continuously monitor their alcohol offenders to ensure they're not drinking. Because SCRAM continuously monitors offenders — as often as every half hour around the clock — it is a much more effective and reliable alternative to random testing methods or incarceration.

The SCRAM Bracelet

The SCRAM ankle bracelet — the heart of the SCRAM system — is attached to the offender with a durable and tamper-proof strap. It is worn 24/7 by the offender for the duration of his or her court-ordered abstinence period (typically 90-120 days).

Twice an hour, the bracelet captures transdermal alcohol readings by sampling the insensible perspiration collected from the air above the skin. The bracelet stores the data and, at pre-determined intervals, transmits it via a wireless radio-frequency (RF) signal to the SCRAM modem.

The SCRAM Bracelet Attributes

  • Tamper and water resistant
  • Samples insensible perspiration every 30 minutes (2x per hour)
  • Automatically collects, stores, and transfers all data via the SCRAM modem on a predetermined schedule (at least 1x/day)
  • Date and time stamps for easy reporting and analysis

The SCRAM Modem

The SCRAM modem is the mechanism by which the data that is collected by the SCRAM Bracelet gets transmitted to Alcohol Monitoring Systems (AMS) for analysis and reporting.

When the SCRAM bracelet is installed on the offender's ankle, he or she also receives the SCRAM modem, which plugs into an analog telephone line — usually in the offender's home or place of work. At a pre-scheduled time(s) each day, the SCRAM bracelet "communicates" with the SCRAM modem, and the modem retrieves all available data from the bracelet. The modem also downloads monitoring and reporting schedules to the bracelet.

The SCRAM Modem Attributes

  • Plugs into any telephone LAN line
  • Stores alcohol readings, tamper alerts, and diagnostic data uploaded from the SCRAM bracelet
  • Sends all data to SCRAMNET over the phone line
  • Downloads monitoring and reporting schedules from SCRAMNET to the SCRAM bracelet


When data is received from the SCRAM modem, it is stored in SCRAMNET, the web-based application managed by AMS where offender data is collected, analyzed, and maintained in a secure, central location.

Where the SCRAM bracelet is the heart of the SCRAM system, SCRAMNET is the brains. It is the information hub that not only houses all offender data, but lets you manage it in the way that is the most effective for your offender management program.

SCRAMNET provides a wide range of reports and graphs at your fingertips — from a snapshot of a single event to a comprehensive view of an offender's behavior over time. SCRAMNET lets you customize and easily tailor the reporting that best suits your needs and individual cases, and helps reduce your workload through exception-based reporting.
