Additional information:

🛠 Periodic Calibration Requirement – Follow the manufacturer’s requirements to ensure the system functions properly: Calibration of the Measurement Module (breathalyzer) once a year. This must be performed at an authorized service center. Only the Measurement Module should be sent; to prevent the vehicle from being taken out of service, a spare unit (if you do not have one, Keragon can provide it) or the system is switched to emergency mode, in which case no alcohol test will be triggered. Alcolock V3 is not a metrological measuring instrument and does not require additional certification from the Bulgarian Institute of Metrology.

⚠Emergency Mode – in the event of a problem, the driver can bypass the system by switching it to emergency mode using a code provided by a dispatcher or immediate supervisor. Once emergency mode is activated, the system will not require an alcohol test for several days (the duration is configurable). This allows the driver to complete the route and take the vehicle to a service center designated by the responsible authorities for inspection. At the service center, the system will be inspected and repaired. The violation data will be reviewed and analyzed —to prevent attempts at abuse by the driver. If the driver does not take the vehicle in for inspection by the end of the set emergency mode, the system will lock the ignition until authorized specialists arrive.

✅ Easy installation – can be installed in virtually any vehicle or machine: passenger cars, minibuses, buses, trucks, forklifts, agricultural machinery, construction cranes, trains, regardless of the type of drive system. In certain cases, such as with refrigerated trucks, the braking system may be disabled to ensure uninterrupted operation of the refrigeration unit.  Installation can be performed by a qualified technician at the vehicle’s authorized service center or at a trusted service provider.
