1.0 ALCOLOCK LR ALCOHOL INTERLOCK PRODUCT
PROFILE
The ALCOLOCK LR alcohol interlock controls the normal operation of a vehicle
through connection with the power, starter and control systems. To start the
vehicle engine, the driver must provide an accepted breath test with a breath
alcohol concentration (BrAC) below the preset limit. During operation of the
vehicle, the driver will be requested to provide additional breath tests to maintain
compliance with program requirements. The ALCOLOCK LR device will never
cause the vehicle engine to stop.
The ALCOLOCK LR device consists of a Handset (HS) to conduct breath alcohol
tests, and an Electronic Control Unit (ECU) that is connected with the power and
control circuits of the vehicle. The ALCOLOCK LR device includes a GPS patch
antenna – connected separately – that logs the coordinates of the vehicle.
The ALCOLOCK LR device is used in alcohol interlock programs under the
direction of a jurisdictional authority and conforms to international regulations for
alcohol interlocks being used in compliance programs.

ALCOLOCK LR7
8.2 INSPECTING THE VEHICLE CHARGING SYSTEM
1. Visually inspect the condition of all wires and belts that connect to the starter,
alternator, and battery.
2. Check if the battery warning light on the dashboard is on, or observe the
voltmeter in the dashboard for at least 14 volts (for the 12 volt device), or at
least 26 volts (for the 24 volt device).
8.3 INSPECTING THE VEHICLE STARTING SYSTEM
If a vehicle starting problem is detected, attach a digital multimeter to the battery
terminals and observe the voltage as the vehicle engine cranks.
If the voltage is below 9 volts (for the 12 volt device), or below 19 volts (for the
24 volt device), or there is no cranking, it is the client’s responsibility to have the
vehicle repaired elsewhere before continuing the installation.
9.0 MOUNTING THE ALCOHOL INTERLOCK ECU
1. Locate an ECU mounting position that is convenient and accessible –
preferably under the dashboard. Ensure that there is sufcient space for the
ECU cable wires to be securely incorporated into the vehicle wire loom.
ATTENTION!
• The ECU and cabling must not obstruct the physical operation of the vehicle
• Do not install the ECU near the vehicle brake and accelerator pedals
2. Position the ECU so that it is elevated, with the cable connector opening
facing downwards. This is to protect the open side of the ECU from
contaminants, such as water leakage and dust.
3. Fasten the ECU to the mounting position with the supplied tie wraps.
NOTE: Always use existing hardware and holes to minimize vehicle
modication.
4. Ensure that the connection is tight and secure.
10.0 MOUNTING THE ALARM HORN
The alarm horn (79-000916) is installed under the hood and is wired to the
alcohol interlock ECU cable. It is programmed to activate when the client has
failed to respond to a retest request past the set limit.
ATTENTION! The alarm horn is intended for installation on vehicles with +12 volt
electrical systems only.
1. Locate an alarm horn mounting position under the hood. Ensure that there
is sufcient clearance so that closing the hood does not damage the hood or
the alarm horn.

2. Position the alarm horn facing downwards. This is to protect the alarm horn
opening from contaminants, such as water leakage and dust.
3. Mount the alarm horn bracket to the vehicle.
NOTE: Always use existing hardware and holes to minimize vehicle
modication.
4. Ensure that the connection is tight and secure.
5. Attach the alarm horn wires to a probe. Feed the wires through the vehicle
rewall and leave sufcient wire clearance under the dashboard.
11.0 MOUNTING THE ALARM FLASHER (IF REQUIRED)
The alarm asher (79-000300) is installed to the exterior of the vehicle – usually
the front license plate -- and is wired to the alcohol interlock ECU cable. It ashes
when the client has failed to respond to a retest request past the set limit.
NOTE: Skip this section if a retest alarm is not required.
ATTENTION! The alarm asher and cabling must not obstruct the normal operation
of the vehicle.
1. Locate an alarm asher mounting position – preferably under the front
licence plate.
2. Mount the alarm asher bracket using screws or tie wraps.
NOTE: Always use existing hardware and holes to minimize vehicle
modication.
3. Ensure that the connection is tight and secure.
4. Attach the alarm asher wires to a probe. Feed the wires through the vehicle
rewall and leave sufcient wire clearance under the dashboard.
NOTE: If possible, use existing wiring harness grommets.
12.0 MOUNTING THE RETEST ALARM (FOR HEARING-
IMPAIRED)
An alarm asher (79-000300) may be separately used as a retest alarm for
hearing-impaired drivers. It is connected to the vehicle interior and is wired to the
alcohol interlock ECU cable. It ashes when a retest is required. When an alarm
asher is used as a retest alarm, it uses a different ECU wire connection than the
exterior alarm asher.
NOTE: Skip this section if a retest alarm is not required.
ATTENTION! The retest alarm (alarm asher) and cabling must not obstruct the
normal operation of the vehicle.
1. Locate a mounting position in the vehicle interior, within the driver’s view –
preferably on the dashboard.

2. Mount the alarm asher bracket using an automotive fastening system
(27-000028).
3. Ensure that the connection is tight and secure.
4. Run the wires neatly to the ECU location under the dashboard.
13.0 LOCATING THE TACHOMETER SIGNAL WIRE
NOTE: Skip this section if the vehicle tach reading will be obtained using vehicle
OBD-II.
ATTENTION! Never use an individual coil pack or fuel injector as a tach source.
Doing so may damage the vehicle fuel injector.
Use the tach nder or the digital multimeter to locate and verify the tachometer
signal wire.
To verify the rpm, (with the vehicle in park / neutral) press the accelerator pedal
and steadily increase the engine rpm.
NOTE: If a tachometer signal is not located, use a permanent Digital Tach Sensor
(DTS) (94-001890) on the alternator. Refer to the Automotive Diagnostic Tool
Instruction Manual (94-000196) and the Tach Sensor Installation Manual (60-000469).
14.0 CONNECTING THE ALCOHOL INTERLOCK ECU CABLE

15.0 ATTACHING THE HS AND ECU
Before attaching the HS and the ECU, the ECU must be mounted and all ECU
wires must be connected.
ATTENTION! Do not solder or apply heat shrinks or tamper-proof labels until all wires
have been attached and post-installation testing has been performed.
1. Connect the ECU cable (13-001102) to the ECU main
input. The cable clicks into place and the ECU beeps.
2. Connect the non-coiled end of the HS cable (13-001100)
to the ECU HDMI port.
ATTENTION! Do not install the HS enclosure until instructed.
