Private Interlock SystemsPrivate or Commercial Use

Alcohol interlocks for private and commercial use are available for purchase or hire and are completely programmable to meet the owner’s requirements.

If you are a business owner who requires employees to drive, you must make sure they are 100% safe on the road each day. An alcohol interlock system can help employers monitor any unlawful behaviour in company vehicles. Alternatively, if you have an employee who has made a mistake with alcohol but requires access to a vehicle for their occupation, as the employer, you may require such employees to use an alcohol interlock system to ensure road safety.

Guardian’s Dignita AL100 interlock system is designed to cater to various needs, ensuring accessibility and affordability. Here’s a breakdown of the pricing options:

Purchase Option: For those who prefer outright ownership, the Dignita AL100 interlock can be yours for a one-time payment of $1,775. This option provides you with full control and ownership from day one.

Leasing Option: If you’re looking for flexibility, Guardian offers a leasing option at just $90.00 per month. With a minimum lease period of 6 months, this choice allows you to access the system without the commitment of ownership.

Rent To Buy Option: For those who wish to test the waters before committing, the “Rent to Buy” arrangement could be ideal. At $160 per month over a 12-month period, you can rent the Dignita AL100 interlock system with the option to purchase it at the end of the rental period.

It’s important to note that installation costs are not fixed and may vary depending on factors such as location and specific installation requirements. Guardian values transparency, and installation costs are arranged directly between the customer and their chosen installation centre. This allows you to choose the most cost-effective installation solution for your needs.

If the interlock device detects alcohol in the driver’s breath sample, indicating that they may be driving under the influence, the device will register a ‘fail’ and prevent the ignition from starting, commonly known as a ‘lockout.’ This safety measure is designed to prevent drunk driving and protect both the driver and others on the road.

After a set period, the driver will be able to complete another breath test. If they pass, they can start the vehicle normally. If they fail again, they will need to wait another set period before attempting another test.

The device will also record information about the failed test, including the date, time, and alcohol level detected. The owner of the vehicle will be notified of the failed test and may be required to report the incident to authorities, depending on the laws in their jurisdiction.

Alcohol interlocks are devices used to prevent individuals from driving while under the influence of alcohol. They are fitted with anti-tamper systems that require a specific breath sample volume to be provided. Additionally, random breath samples are requested throughout the journey. If tampering is suspected, the vehicle will be disabled using a specific device or system. In such cases, the driver will be liable for a service fee.

There could be a number of reasons for failing a breathalyser test – certain foods or mouthwash containing alcohol, for example. To minimise the risk of a false positive, we recommend that you do not eat or drink for 5-15 minutes prior to taking the test and that you rinse your mouth with water first. If you think this may be the reason for your test failure, wait a few minutes and try again. Your user manual provides you with advice on this. If you continue to have problems with your interlock device, please contact Guardian or your nearest service centre for advice.

Yes, other individuals can drive your car even if an interlock device is installed, but there are important considerations to keep in mind.

The interlock device is designed to prevent the vehicle from starting if the driver has a measurable amount of alcohol in their breath. This means that any driver, not just the owner of the car, must pass the breath test to operate the vehicle.

It’s crucial to remember that as the owner of the vehicle, you are responsible for any readings recorded by the device. Therefore, if another person drives your car and fails the breath test, this will be recorded as a violation on your account, which could lead to penalties or an extension of the required interlock period.

For this reason, it’s important to ensure that anyone who drives your car understands how to use the interlock device and is aware of the implications of a failed test.

An ignition interlock device is a small, electronic mechanism installed in a vehicle to prevent drink driving. It works by requiring the driver to provide a breath sample before the vehicle can start. The device measures the alcohol content in the breath sample and if it’s above a pre-set limit, typically very low to ensure no influence of alcohol, the vehicle will not start.

Additionally, the device requires random retests while the vehicle is in operation, ensuring continued sobriety during a journey. The data from each breath test is recorded and can be reviewed by authorities or interlock program administrators.

This device is often mandated by courts for individuals convicted of drink driving offences, helping to promote responsible driving habits and ensuring road safety.
