Integration with breathalyzers

Ask a question

Alcohol-testing functionality in Sigur will check your employees at the checkpoint and deny access to the workplace if an employee is intoxicated.

Modification of Dingo alcometers

In partnership with СМС2, the official distributor of Dingo alcometers in Russia, we developed a special firmware for Dingo B-02 devices, which extends the basic functionality of the alcometer.
For example, instead of discrete test results such as “alcohol detected” or “alcohol not detected” in the exhaled air, this modification will show accurate test results in per mille.

Advantages of the integration

Sigur is compatible with popular models of alcometers such as Dingo B-01 and B-02 as well as with Alcoframe and Alcobarrier devices. The functionality depends on the device chosen and its modification.

An extended functionality that identifies not only the fact of intoxication but also provides an accurate result in per mille is available in Alcobarrier, Alcoframe and Dingo В-02 with Sigur firmware. Dingo В-01 devices in Sigur can operate only in a discrete mode.

This integration provides flexibility of configuration of testing and access rules:

  • You can set the maximum alcohol content in per mille, reaching which an employee will not be allowed to the workplace
  • Deny access if an employee has been tested positive for alcohol
  • Allow access even if an employee has been tested positive for alcohol and register the fact in the system
  • Select which checkpoints will require a test for alcohol and which will not and choose the direction
  • Set the testing frequency, e.g. test every third or fifth employee, to speed up the traffic through the checkpoint

Connection of alcometers

Dingo and Alcobarrier alcometers are connected locally to any available port of the reader of Sigur controller. You will need to reassign the ports of the reader to reflect the alcometer connection port, direction (entry or exit) and the checkpoint. Alcoframe is connected via an IP network and is configured in a software.

After that, Sigur will collect events from the alcometer. They can be turned off in the settings by choosing which types of events to show in the monitoring screen editor.

How alcometers work and their maintenance

Dingo B-02

Dingo alcometers are equipped with electrochemical sensors designed for a large traffic of people and non-stop operation. You can buy replacement sensors and easily replace the old ones. As far as we know, each sensor unit will handle up to 10,000 exhalations of a sober person. Exposure to alcohol vapors will reduce the lifetime of the sensor. Testing time: 2 to 3 seconds to exhale and 2 to 3 seconds to analyze. If the exhaled air contains alcohol, the test will take longer.


Alcobarrier alcometers are also equipped with electrochemical sensors. A pressure sensor is used as an expiratory sensor. It controls the expiratory duration and volume and the sample for testing is taken at the final moment of the exhalation (i.e. the deep air from the lungs is analyzed), which improves the reliability and accuracy of the results.

The time to analyze the samples and return the device in a standby mode with a clean breath is about 4 seconds. If the sample contains alcohol vapors, it will take up to 6 seconds. The lifetime of a continuously operated inbuilt electrochemical sensor is at least two years and the average lifetime of the gas sensor is 5 years. If the gas sensor is operated under conditions of more than 10,000 tests per month, it is recommended to check the gas sensor at least once every three months. Check: once every 12 months.


To detect alcohol vapors, Alcoframe uses an innovative diode laser spectroscopy method. The lifetime of Alcoframe is least 50,000 hours. Detection does not require any contact which eliminates the need to use any consumables or individual protection gear such as mouthpieces or tips. The device has an integrated self-diagnostic tool and does not require regular adjustments and checks. Maximum analysis time is 1.5 seconds.
