102 Entrance, Internal, Sliding & Bi-folding Doors Also online at: www.dijonline.co.uk THE door industry journal winter 2025 How Door Coordinators Ensure Double Fire Doors Close in Perfect Sequence Allegion UK, a leading name in fire safety hardware and supplier of the Zero Z304 CE fire door coordinator, highlights the vital role of door coordinators in buildings with double fire doors. When your building relies on paired fire doors to create a strong barrier, the sequence in which those doors close is just as important as the doors themselves. A mis-timed closing can create dangerous gaps, allowing fire and smoke to pass through the building instead of maintaining a continuous, protective seal. This is why door coordinators are essential components for ensuring safety and integrity of double fire doors. Iain Banks, Product Marketing Manager at Allegion UK, explains: “All fire doors must be fitted with a door closer to ensure they stay closed. However, double fire doors can pose a dangerous risk if they close incorrectly and become ineffective if not fitted with an appropriate fire door coordinator. A correctly fitted fire door coordinator ensures double fire doors always close in the correct sequence, remain firmly closed, and maintain an effective barrier against fire and smoke.” In other words, the door coordinator is the conductor of a synchronised performance, ensuring both leaves work together to form an effective barrier when every second counts. Providing precision, performance & peace of mind With a unique surface rebate catch, the Z304 guarantees the correct closing sequence of your double fire doors every time. Not simply an enhancement; a door coordinator is a safety-critical component designed to preserve the integrity of passive fire protection throughout the lifecycle of a building. Robust and versatile, the Z304 door coordinator is suitable for both timber and steel fire doors. It provides specifiers, architects, and building managers with rigorous, standards-based assurance, carrying CE and UKCA marks to EN 1158:1997 and being assessed to BS EN 1634-1:2014. In a sector where compliance and performance are non-negotiable, the Z304 CE fire door coordinator offers tangible peace of mind that the product will perform as intended in real-world conditions. Iain Banks continues: “The Z304 fire door coordinator prevents double doors from operating out of sequence, eliminates unintended gaps, and supports a building’s passive fire protection strategy. It also simplifies maintenance, reduces callouts for misaligned doors, and demonstrates a clear commitment to occupant safety and regulatory compliance.” A dependable door coordinator is essential when double fire doors are expected to do precisely what the design intends, stopping the spread of fire and smoke in its tracks. The Zero Z304 CE fire door coordinator embodies Allegion UK’s commitment to safety, reliability, and practical performance for the most demanding commercial environments. www.zeroplus.co.uk
