Overview

The prEN 50436-4 standard, developed by CLC and submitted to CENELEC, focuses on connectors for electrical connection between alcohol interlocks and vehicles. It is part of a broader series of European Standards aimed at ensuring reliable test methods and performance requirements for alcohol interlocks. This standard specifies the interface, connector types, and pin assignments to facilitate after-market installation of alcohol interlock devices in vehicles without interfering with vehicle functionality.

Although the project was later stopped by CLC/BTTF 116-2, the document remains a valuable reference for manufacturers of alcohol interlocks and vehicle manufacturers seeking standardized electrical interfaces.

Key Topics

• Purpose and Scope
  The standard covers the interface between alcohol interlocks and vehicles, specifying connectors for supply voltage, data transfer, and optional output functions. It applies both to alcohol interlocks used in drink-driving offender programs and general preventive use.

• Connector Types
  Three connector types are defined to standardize electrical connection:

  • Connector 1: Supplies vehicle voltage and controls the starter relay.
  • Connector 2: Transfers information between the vehicle and alcohol interlock.
  • Connector 3 (optional): Provides outputs like horn or lights activation upon specified events (e.g., missed retest).

• Connector Specifications
  Each connector has detailed physical and electrical properties including:

  • Wire cross-section (e.g., 2.80 mm² for Connector 1)
  • Male plug and pin configuration
  • EWCAP standardized connector types for easy vehicle integration

• Pin Assignment & Functionality
  The standard outlines specific pin assignments for each connector pin based on their purpose:

  • Power supply inputs at 12 V and 24 V levels
  • Ground connection
  • Signals for ignition, engine status, and vehicle movement
  • Control of starter relay, horn, and vehicle lights via potential-free connections
  • Pre-heat inputs to reduce power consumption when vehicle is idle

• Installation Objectives
  Designed for seamless, cost-effective after-market installations, these standardized connectors aim to:

  • Minimize interference with vehicle electrical systems
  • Reduce installation complexity and costs
  • Enhance interoperability across vehicle makes and alcohol interlock models

Applications

• Drink-Driving Offender Programs:
  Ensures reliable electrical integration of alcohol interlocks that prevent vehicle start without a successful breath test, increasing road safety and compliance.

• General Preventive Alcohol Interlock Use:
  Supports devices aimed at general alcohol testing in vehicles to deter drunk driving beyond legal enforcement scenarios.

• Aftermarket Vehicle Upgrades:
  Enables vehicle owners and fleets to install alcohol interlocks quickly and correctly, without extensive rewiring or technical barriers.

• Vehicle Manufacturing and Component Design:
  Vehicle manufacturers can implement pre-standardized connectors to facilitate the fitting of alcohol interlocks during production or retrofitting.

Related Standards

The prEN 50436-4 is part of a comprehensive series addressing alcohol interlock devices:

• EN 50436-1: Test methods and performance requirements for instruments targeting drink-driving offender programs.
• EN 50436-2: Test methods for instruments with mouthpieces measuring breath alcohol for general preventive applications.
• EN 50436-3: Guidance covering selection, installation, use, and maintenance of alcohol interlocks.

Introduction
Alcohol interlocks are often intended for after-market installation. For this purpose they have to be
connected to the electric circuits of the vehicle.
This installation of an alcohol interlock should not interfere with the proper performance of the vehicle
and should be as easy and as fast as possible. Additionally, the installation costs should be low in
relation to the total cost of the alcohol interlock.
Therefore, it is desirable to have a standardized interface between alcohol interlocks and vehicles.
