    Implications of the EU Low Voltage Directive on Battery Usage


    The European Union (EU) continues to prioritise protecting its citizens and harmonising regulations across its member states in the ever-evolving landscape of technology and safety standards. Recently, the EU Low Voltage Directive (2014/35/EU) has been extended to the usage of batteries operating with a voltage between 50-1000V AC and 75-1500V DC, and it has significant implications for installing and maintaining fire and security systems. It's worth noting that the directive excludes 12v DC batteries.


    The EU Low Voltage Directive: A Brief Overview


    The EU Low Voltage Directive, introduced in 1973 and revised in 2014, sets out essential safety requirements for electrical equipment operating within certain voltage limits. The directive aims to ensure a high level of protection for individuals and property by mitigating risks associated with electrical installations.


    The latest iteration of the LVD, which came into effect recently, places renewed emphasis on enhancing safety standards across various sectors, including fire and security systems. Among its provisions, the directive addresses the utilisation of batteries, recognising their crucial role in powering these essential systems. 


    Batteries in Fire and Security Systems: Importance and Challenges


    Fire and security systems rely on battery backup to ensure uninterrupted operation, especially during power outages or emergencies. However, the use of batteries introduces unique challenges related to safety and reliability.

    Traditional lead-acid batteries, commonly employed in fire and security installations, pose risks such as leakage, overheating, and environmental contamination. Moreover, technological advancements have led to adopting lithium-ion batteries, which offer higher energy density and longer lifespans but also present concerns regarding thermal runaway and fire hazards if mishandled or improperly installed.


    Implications for Installers Relating to the LVD on Battery Usage


    The introduction of the EU Low Voltage Directive holds significant implications for installers, especially concerning using fire-retardant batteries in designing, installing, and maintaining fire safety, access control, video surveillance and intrusion systems. The Fire Industry Association (the UK's largest fire protection trade association) has issued guidance in response to this directive. This FIA guidance encourages all fire and security system batteries to possess a UL 94 V-2 or superior flammability rating (Refer to the table below for detailed specifications). Installers and maintenance technicians need to ascertain whether the batteries utilised in fire and security systems require flame retardancy. In cases where specifications are absent, opting for flame-retardant (FR) batteries as a precautionary measure is advisable. For a list of ADI's LVD-compliant batteries, click here

    Other key aspects of the directive pertinent to battery usage include:

    Safety Standards

    The LVD mandates adherence to stringent safety standards for electrical equipment, including batteries, to minimise the risk of hazards such as electric shock, fire, and environmental damage. Installers must ensure compliance with relevant safety directives and standards, conduct thorough risk assessments, and implement appropriate mitigation measures.

    Product Compliance

    Manufacturers of batteries and associated electrical equipment must demonstrate compliance with the essential requirements outlined in the LVD. Installers play a crucial role in verifying the conformity of components used in fire and security systems and selecting products that meet the prescribed safety criteria and performance standards.

    Installation Practices

    The directive emphasises the importance of proper installation and maintenance practices to uphold safety and reliability standards. Installers must possess the requisite knowledge and skills to integrate batteries into fire and security systems correctly, following manufacturer guidelines and industry best practices to mitigate potential risks.

    Documentation and Certification

    Documentation is vital in demonstrating compliance with LVD requirements. Installers should maintain detailed records of equipment specifications, installation procedures, and test results, facilitating traceability and accountability throughout the system lifecycle. Certification bodies may also conduct audits or assessments to verify compliance with regulatory requirements.

    Training and Education

    In light of evolving safety standards and technological advancements, ongoing training and education are essential for installers to stay abreast of relevant regulations and best practices. Training programs focusing on battery safety, installation techniques, and regulatory compliance can empower installers to perform their duties effectively and responsibly.


    Challenges and Opportunities for Installers


    Implementing the EU Low Voltage Directive presents challenges for installers regarding compliance, but it also offers opportunities for professional growth and differentiation. By embracing the principles of safety, quality, and continuous improvement, installers can enhance their reputation as trusted providers of fire and security solutions.


    Moreover, the transition towards safer and more efficient battery technologies, driven by regulatory requirements and market demands, opens up avenues for innovation and collaboration within the industry. Installers can leverage emerging technologies such as advanced battery management systems and remote monitoring capabilities to optimise system performance and enhance reliability.




    Including batteries in the EU Low Voltage Directive heralds a new era of enhanced safety standards and regulatory oversight in fire and security systems. Installers play a pivotal role in ensuring compliance with the directive's provisions, particularly concerning the use of batteries. By prioritising safety, adherence to standards, and ongoing professional development, installers can navigate the regulatory landscape effectively while delivering reliable and resilient solutions to safeguard lives and property.
