Automatic Opening Vents (AOVs) play a crucial role in smoke ventilation, ensuring that buildings remain safe for occupants during emergencies. For developers, architects, and contractors in the UK, compliance with EN12101-2 is not just a recommendation—it’s mandatory under UK law, as per the Construction Products Regulation (CPR) 2013. But how can you ensure that your AOV systems meet these stringent standards? The key lies in obtaining a Declaration of Performance (DoP), the only valid proof of compliance. In this blog, we’ll explore the requirements for AOV systems, the importance of compliance, and how the correct documentation ensures safety and legality.
Why Compliance with EN12101-2 is Crucial
The EN12101-2 standard governs smoke and heat control systems, including AOVs, which are critical for life safety in buildings. Compliance with this standard is not just about meeting legal obligations—it directly affects the safety of building occupants. When an emergency occurs, a properly functioning AOV system can be the difference between life and death by allowing smoke to escape and reducing the risk of smoke inhalation for occupants and first responders.
According to UK law, any smoke ventilation system, including vents, must adhere to EN12101-2. This ensures that the vent and actuator are tested together as a complete system at an accredited facility. Once tested, the installation must replicate the test setup exactly, ensuring the system will perform as required in real-world scenarios.
The Role of the System 1 Categorisation
AOVs fall under a ‘System 1’ categorisation, meaning they are classified as life safety products. This adds an extra layer of responsibility for both the manufacturer and installer. Under System 1, manufacturers must be audited by a notified body to ensure their production processes meet the strict Factory Production Control requirements. This guarantees that each AOV is produced to the highest standards, with safety at the forefront.
Actuators, the mechanisms that control the opening of vents, must also be installed following this process, ensuring the entire system—from manufacturing to installation—is fully compliant.
Obtaining Proof of Compliance: The Importance of the DoP
At the conclusion of the testing and manufacturing process, the manufacturer, such as SE Controls, will issue a Declaration of Performance (DoP) in accordance with EN12101-2. This document is the only valid proof that your AOV system complies with the necessary regulations. It provides essential information about the performance of the vent and actuator system and certifies that it has been manufactured and installed in compliance with all applicable laws and standards.
In addition, the DoP allows the manufacturer to apply the UKCA mark, indicating that the AOVs meet the required UK standards for smoke ventilation. Without this proof, your project could face delays, or even non-compliance issues, at the building control approval stage.
Why the DoP is Non-Negotiable for Building Control
When your building project reaches completion, Building Control will likely request proof of compliance for the smoke ventilation system. The Declaration of Performance (DoP) serves as this essential proof, ensuring that your AOV system meets EN12101-2 and all UK regulatory requirements.
Failure to provide a valid DoP could result in costly delays, fines, or having to rework your installation to meet compliance standards. It’s not just about avoiding penalties—it’s about ensuring the safety of the people who will occupy the building for years to come.
Conclusion: Prioritising Compliance for Safety and Success
Ensuring that your AOV system complies with EN12101-2 is essential for both legal compliance and the safety of your building’s occupants. By choosing a manufacturer that adheres to System 1 Factory Production Control, you can have confidence in the quality and reliability of your smoke ventilation system. Always make sure to obtain the Declaration of Performance (DoP) for your project, as it will be a crucial part of your building’s approval process.
