"Sentry," Passive Alcohol Sensor
notes: label: Description
content: This device is a box that can be hung on the wall at the entry to an area to be kept alcohol free. The first such unit was the Alcosentry developed by Robert Voas working with Lion Laboratories. That device was designed for use in community corrections facilities for DUI drivers where the residents were allowed out during the day to work were prohibited from drinking. The Alcosentry unit stood at the door and the returning resident had to speak into it to report his or her return to the site. The unit and a voice recognition system which verified the offender’s identity and captured a breath sample for BAC analysis, with an alarm system if alcohol was detected. From that idea, PAS Systems International, Inc. picked up the sentry concept –a box that can be hung up on the wall and users speak into it. It recorded the voice and captured enough air to test for BAC. The device has a scale in the middle that rises according to alcohol level. Most sales of this device were to schools. In situations where a student would be obviously under the influence of something, but when the parents were called they would claim that their child never touches alcohol. School principals could use this device to demonstrate that there was a positive alcohol level reading. It could also be used at high school dances and sporting events to prevent students who have been drinking from entering the event. For last 20 years, essentially all passive sensors have been produced by Jerel Kelsey’s operation.
