Yes, you have to use a mouthpiece for all of the breathalyzer units. It is not recommended to reuse mouthpieces due to hygiene and potential damage to internal components in the device. If you do use it more than once please make sure it's clean!

The readings displayed on the breathalyzer shows the BAC (Blood Alcohol Concentration) level of the breath sample.

Both terms are relevant to each other; however, some countries use BAC and some use BrAC.

Yes, depending on the temperature threshold of the device. Please consult the instruction manual for further information.

Store your device indoors, at room temperature when not in use. Ensure that the breathalyzer is not used/stored in extremely hot or cold environments or in direct light for prolonged periods of time. When stored inside it acts like an awesome car protection device!

Generally, people convicted of drink-driving offences are required to use an alcohol interlock system. However, it might also be used as a preventive measure for personal use or in commercial vehicles in some regions to improve road safety.

An alcohol interlock device is a breath-testing unit installed in a vehicle's ignition system, preventing it from starting if the driver's breath alcohol level exceeds a pre-set limit. This ensures the driver is sober before allowing the vehicle to be started.

Alcohol interlock systems are designed to be highly accurate and reliable, utilising advanced fuel-cell technology or semiconductor sensors to precisely measure breath alcohol concentration. They’re also often subjected to rigorous testing and calibration to ensure they meet regulatory standards.

Alcohol interlock devices may be used in may settings. It is often used in different commercial settings, such as transport trucks, public transportation, school buses, and ships. Alcohol interlocks devices are also used in mandated alcohol interlock programs. More recently, private users are requesting to install these devices in their vehicles to protect familiy members and your drivers from poor decisions.

An ignition interlock consists of a handset to conduct breath alcohol tests with and relays messages to the driver and an Electronic Control Unit (ECU) that is connected to the power and control circuits of the vehicle.

Before starting the vehicle, a driver must provide a breath sample, and within seconds the alcohol interlock device analyses the breath sample and displays instructions to the driver. If the driver's breath alcohol concentration (BrAC) is above a pre-set limit, the vehicle will not start. If the breath is below the threshold the vehicle can be started. Once the vehicle is started, the alcohol interlock device can be set to ask the driver to provide breath samples at random times while the engine is running; or set to ask the driver to provide only an initial test at startup.

At our Service Centres, we ensure that every installation goes smoothly and according to plan. Our trained technicians are certified and know exactly how to treat your vehicle. If, however, you experience difficulties with your ignition interlock, please contact us for assistance on 1-800-252-656

During normal operation, the device requests the driver to provide additional breath samples at fixed or random intervals to ensure that alcohol has not been consumed since starting the engine.

Our ignition interlock devices will never cause the vehicle engine to stop. The handset will beep to notify you of the retest request, and the timer will activate and give you sufficient time to stop in a safe location before providing a breath sample. We do not recommend performing a breath test while the vehicle is in motion.

We also install ignition alcohol interlocks on motorcycles, but certain modifications may apply.

Yes, an instruction manual is available for the ALCOLOCK LR Handset. Click here to download the manual.

The ALCOLOCK LR Interlock controls the normal operation of a vehicle through connections that interrupt the start sequence. To start the vehicle, the driver must provide an accepted breath sample with an alcohol concentration below the preset limit of 0.002.

 

During the operation of the vehicle, the driver will need to provide additional breath samples to ensure continued compliance with program requirements.

 

The ALCOLOCK LR Interlock device WILL NOT shut off your vehicle during operation.

1. Keep the unit clean and dry at all times. Ensure handset is stored away from direct sunlight and contact with any liquids.

2. It is recommended to clean the handset each time after driving. DO NOT use any solvents or wet cloth on the handset, only a dry clean soft cloth.
3. Use a clean and dry mouthpiece when providing breath samples. It is recommended that you clean or exchange the mouthpiece regularly and do not share the mouthpiece with another user.
4. Do not eat food or consume alcohol before using your ALCOLOCK LR Interlock device.
5. Do not use alcohol-based products, including mouthwash before using your Alcolock LR Interlock device.

6. Do not smoke/vape before using your ALCOLOCK LR Interlock device. Tobacco will block the device. 
7. Your Blood Alcohol Concentration (BAC) can continue to rise for up to 2 hours after your last drink and it can take a further 10 hours for your body to return to a zero reading after large volumes of alcohol have been consumed.
8. Make sure air in your vehicle is not contaminated with alcohol or solvent vapours, e.g. air fresheners/Glen 20.
9. Ensure that the breath test is provided from the driver’s seat in order for the test to be accepted.
10. Do not tamper with the camera. Recorded violations with no photo will automatically be assigned to the registered participant on the program.
11. Avoid placing the interlock on the vehicle floor. If the device is not secured, it may interfere with the pedals and safe operation of the vehicle. Store in a secure and safe place.
12. If you are asked for a random breath test whilst driving, you have 7 minutes to present the breath test, do so in the safest possible way to yourself. Do not turn the vehicle off.
13. You must not tamper with, abuse, misuse and/or neglect the interlock device, equipment or camera. This may result in additional costs for repair or replacement of equipment. You are liable for any damage from misuse, abuse or neglect of the device. 

14. If liquid spills onto the handset remove excess liquid with a clean, dry cloth and allow it to
dry thoroughly. If there is substantial moisture damage, do not activate the handset.

The handset will display a reminder message 7 days BEFORE the scheduled date warning that a service is due. Failure to bring the vehicle into a service center for scheduled services means the device will enter a permanent lockout state seven (7) days AFTER the scheduled date.


Note: The Jurisdiction is advised of all missed service appointments and other program violations that may result in a program extension.

An immediate recall can be caused by many reasons, for example:
– Failed breath tests
– Failure to complete a Retest
– Power loss / battery disconnection
– Tampering with the ALCOLOCK LR Interlock device
– Attempting to start the vehicle before or without completing an acceptable breath test

As an example. When you turn your ignition to accessories before completing an acceptable breath test, an immediate recall error will occur followed with a date. Failure to reset the device before the displayed date will result in a permanent lockout. 


For any recall you will need to contact Affordable Interlock Systems on 1-800-252-656. Do not leave it to the last minute to ring!

The handset will display permanent lockout, a number and the lockout date. The device will not accept a breath test and the vehicle will not start.

 

This occurs as a result of failing to address previous device notifications or to attend a scheduled service appointment within the seven (7) days grace period.
 

NOTE – refer to your Instruction manual for all display / error messages

After a failed initial breath test due to detection of alcohol by the interlock, the vehicle will not start and a temporary lockout will be activated. Another breath test can be presented after the countdown is finished.

 

NOTE – refer to you Instruction manual for further information.

The time on the interlock program is advised by your applicable Jurisdiction and can vary depending on the offence and state. Completion of the program is demonstrated by sufficient and prolonged responsible driving behavior. Any violations of the program can extend the period of participation. Please consult with your state’s alcohol interlock program using the following:

Yes, any other person can drive a vehicle that is fitted with an alcohol interlock and therefore should be trained on how to use the device. However, they will also have to provide a successful breath sample in order to start the vehicle. The participant of the program is responsible for any readings that are recorded on the device.

No, the alcohol interlock uses minimum battery power, it would take years to drain a battery. Problems will only occur if there is ALREADY an electrical problem with your vehicle, such as a defective alternator, or if the vehicle battery is defective.

It is HIGHLY recommended you DO NOT eat or drink anything, other than water, at least 15 minutes before providing a breath sample. These actions may contaminate the breath sample. If any liquids or foods containing alcohol are consumed, it is recommended the driver wait 15 minutes prior to using the alcohol interlock. This is to ensure no mouth contaminate will influence the result. It is recommended to rinse the mouth with water before providing a
breath sample.

Yes, these actions may contaminate the breath sample. Blowing smoke (any type, including vape smoke) directly into the alcohol interlock may affect the device readings. You should wait 15 minutes prior to using an alcohol interlock. It is recommended to rinse the mouth with water before providing a breath sample.

Using any alcohol based hygiene products in the vehicle or directly on person may affect the device readings. To avoid this, you should wait 15 minutes prior to using the alcohol interlock. If you have used any of these products, it is suggested that you open the windows and air out the vehicle.

It is recommended to change the mouthpiece regularly, minimum time after one month, to avoid excess moisture from breath samples. The plastic mouthpiece is reusable and should be washed in warm water only, DO NOT USE DETERGENT OR CLEANING PRODUCTS. Each driver should use their own mouthpiece, it is important not to share the mouthpiece with any other user. Never blow directly into the sampling port without a plastic mouthpiece

To clean the handset, use a damp cloth and mild soap. DO NOT use abrasive cleaners or solvents on the handset as they can damage the handset and may contain alcohol. Ensure that no liquid enters the sampling port or side vent.
Allow handset to air dry for at least 15 minutes, then insert mouthpiece after 15 minutes or before starting the next drive.

The auto repair facility should be informed there is an ALCOLOCK LR Interlock device installed in the vehicle. Direct the auto repair staff to make contact with Affordable Interlocks Systems to obtain a code before starting work on the vehicle. If a tampering violation occurs as a result of work done by an auto repair facility it is the participant’s responsibility to contact Affordable Interlocks Systems on 1-800-252-656.

The short answer is No. The ALCOLOCK LR Interlock device is designed to prevent your car from starting during permanent lockout but cannot stop the engine when it is already running. The engine will only turn off when you manually turn the ignition off. In the event that you miss or fail a retest, and do not take any subsequent tests during the countdown period, alarms will sound and lights flash, however, the vehicle will not automatically shut down unless you manually turn off the ignition. To deactivate the alarms, turn off the ignition.

The best option is to consider removing the interlock from your vehicle. Removal and early termination fees will apply but the monthly rental continues to be charged while the interlock is in your possession, this can end up costing more than the removal. It is a good idea to contact Affordable Interlocks Systems for advice to avoid additional fees or charges.

There could be a number of reasons for this – certain foods and liquids may trigger a detection so it is highly recommended you DO NOT eat or drink prior to taking a test or while driving. Best practice is, prior to taking a test after eating, rinse your mouth out with water first. Refer to your user manual for further advice on this. If you continue to have problems with your Alcolock LR Interlock device please contact Affordable Interlock Systems on 1-800-252-656

Additional breath tests are required at random time intervals to check the driver has not consumed alcohol since the engine was started. After you successfully complete the initial breath test, and the engine is still running, the interlock will continue to request breath samples during your trip at random intervals as follows:


a) The first retest will be requested 3 – 10 minutes after engine starting.
b) Subsequent retests will be requested 15-60 minutes after the previous random retest has been passed, for the duration of your travel.
c) The device will allow 7 minutes for you to safely pull over and complete your retest. DO NOT TURN OFF THE ENGINE
d) TAKE NOTE the device will continue to request random retests while the engine continues to remain running. Even if you have reached your destination, if the device asks for a breath sample you must provide it before turning your ignition off.
e) DO NOT leave your vehicle running and unattended as you may miss a breath test which will record an error on your handset.
 

***WHAT HAPPENS** 

If a random retest fails or is missed, the lights and horn will sound. It is recommended you pull over to a safe location and turn off the vehicle engine which will stop the sounds. This may result in a temporary lockout. After the count-down has ended you will need to provide a successful breath test to start the car.

Violations may include but not limited too:

Failing any requested breath tests

  • After failing an initial breath test you will be locked out for 5 or 30 minutes
  • If you fail a random/rolling retest it is considered a violation. Warning lights and ahorn alarm will sound once this happens. To stop the alarm, you must retest successfully. If you fail retest again, it will record another violation and the alarm will continue until the engine is turned off.

Failure to attend a scheduled service:

  • The date of your next scheduled service will be programmed into your device beforeyou leave the Service Centre. You can attend your scheduled service from 7 days before to 7 days after the programmed date. Failure to attend within this timeframe will result in a violation.

Any tampering with or circumvention of the Alcohol Alcolock LR Interlock device

  • Circumvention is when you drive a vehicle without first providing a breath sample.This is considered a serious violation.
  • If your car battery is disconnected for 20 minutes or more this can record a violation. When doing work on your vehicle make sure that the mechanic is aware of this and that they can contact your service provider to obtain an override code.
Please refer to your applicable program for further details.
