1. A. Any aftermarket alarm or siren installed in a vehicle

by the Authorized Service Provider (ASP) will be installed inside the passenger compartment of the vehicle.

1. B. Upon request of the driver, aftermarket lighting shall

be installed within the vehicle by the ASP to notify hearing impaired drivers of a requested breath test. Such lighting shall be demonstrated to the division upon request.

1. 5. Present a violations reset message when three (3) run-

ning retest breath samples at or above the alcohol retest set point occur within a thirty- (30-) day period or when three (3) running retest refusals are recorded within a thirty- (30-) day period;

1. (E) Violations reset message.

   1. 1. Instruct the operator to obtain device service within

seven (7) days following receipt of the message.

1. 2. Cause the vehicle to enter a permanent lockout condition

when a device is not serviced within seven (7) days;

1. (F) Device calibration.

   1. 1. Utilize calibration devices that are listed on the “Highway

Safety Programs; Conforming Products List of Calibrating Units for Breath Alcohol Testers” established by the United States Department of Transportation, National Highway Traffic Safety Administration, 77 FR 64588-64590 as published in the Federal Register on October 22, 2012 by the National Highway Traffic Safety Administration, 1200 New Jersey SE, Washington, DC 20590 and effective October 22, 2012, which are hereby incorporated by reference and made a part of this rule.

1. (7) days, or during each monitoring service.

   1. 3. Be calibrated for accuracy by using a wet bath or dry

gas alcohol standard with a reference value between 0.02 and 0.050 g/dL BrAC. The solution or gas should have a certificate of analysis that is traceable to the National Institute of Standards and Technology (NIST).

1. 3. Provide near real-time data transmission between the

operator’s device and the manufacturer’s server while the device is in use.

1. 4. Make available for viewing, when a violation occurs, all

data, including photos or digital imaging and global positioning system coordinates, if required, on the manufacturer’s website within ten (10) minutes from when the data was recorded on the device or as soon as cellular transmission will permit. This includes any last event data recorded after power off or as power is restored (e.g., skipped running retest data).

1. 5. Make available for viewing, during normal operation

without violations, all data, including photos or digital imaging and global positioning system coordinates, if required, on the manufacturer’s website within twelve (12) hours from when the data was recorded on the device or as soon as cellular transmission will permit.
