There are several companies that design and install ignition interlock devices. These devices are designed to keep people who have been convicted of driving under the influence (DUI) from starting their vehicle after they have consumed alcohol.
The AMS 2000, designed by Guardian Interlock, is one type of ignition interlock device. This product is both easy-to-use and compact, making it a convenient device for users.
The device prevents tampering in several different ways. When testing for the breath alcohol content, the person using it must first hum on the device. This keeps people from using an air mechanism to thwart the device. The person must also blow into the apparatus and then suck out air, once again ensuring that it is a person and not a machine that is providing the air sample.
This device also self-calibrates, so the driver does not have to take it in for frequent checks. A computer records every action the driver has taken with the ignition interlock device, from when they tried to start the car to what their BAC level was at the time. The computer can store up to 12,000 interactions with the device.
A memo-minder is also a helpful feature on this product. It reminds the driver about their scheduled appointments. If the appointment is missed, the interlock device will be disabled and the car will not be able to start.
The AMS 2000 also provides several alerts for if the machine is tampered with. If a driver tries to drive while bypassing the interlock device, an alarm will be sounded until the car is stopped. The device will also know if the car’s power has been interrupted (i.e., if the driver tampers with the battery.)
If the driver has restrictions on when they are allowed to drive, the device can be programmed to only accept tests taken during those hours.
Smart Start Technology also offers ignition interlock devices. The SSI-1000 is a small device (about the size of a cell phone) that is electronically connected to the automobile’s ignition.
This product features a built-in microchip that records all interactions with the interlock device such as tests results, when the engine was started or stopped, and whether the device was tampered with. All of this data is stored so it can be revieed later.
