Fire and smoke protection are governed by certification of complete assemblies. A door is tested as a system: leaf, frame, seals, hardware and closing devices evaluated together under defined exposure conditions. Approval applies to that configuration as a whole.
Electrifying or modifying a certified door changes its behavior. Even small adjustments can influence closing force, latch engagement, seal compression or structural response. A locking device may hold its own classification, but that does not authorize its installation on any fire-rated door. Compatibility must be validated within the context of the specific door assembly.
In certain cases, adapting a solution between different door manufacturers requires extended application assessment or expert technical evaluation. Without such validation, the original certification scope may no longer apply.
Emergency exit systems introduce an additional regulatory layer. Standards such as EN 13637 define how electrically controlled escape doors must behave in alarm and power-loss scenarios. These standards apply to the complete system configuration. Release devices, locking mechanisms, control logic and power supply form a single functional unit. Substituting elements outside the certified scope compromises compliance.
Our role is to operate within these boundaries. We align solutions with manufacturer documentation, applicable standards and normative expectations. Compliance is not achieved through isolated certifications. It is achieved through system coherence.
Safety is defined by verified behavior, not assumption.
