While sharing the ultra-quiet, frictionless 36V DC Digital Brushless Motor base of the standard Fluo range, the Fire Rated (Spring) Edition integrates a physical mechanical overhead closure spring. This dual-drive setup guarantees that even during a total building blackout or fire alarm power isolation, the door will automatically close under pure mechanical spring tension, sealing off smoke and fire barriers in compliance with strict life-safety building regulations.

Fire Safety & Regulatory Compliance

• EN 1634-1 Fire Resistance: Fully certified and tested to provide up to 120 minutes (2 hours) of physical fire containment integrity when paired with rated fire door blanks.

• EN 1154 Infrastructure: Meets strict European overhead door closer standards, calibrated natively to an EN4 mechanical closing force profile to guarantee complete latching against positive room pressures.

• EN 16005 Pedestrian Standard: Integrated firmware safely manages closing speeds, forces, and obstacle detection thresholds to eliminate impacts on children, elderly, or disabled users.

Core Innovations & Mechanics

• Motor-Open / Spring-Close Mechanics: Under normal day-to-day operation, the 36V brushless motor handles opening cycles with near-silent, effortless precision. The integrated control panel continuously samples encoder feedback to adjust torque against draft or HVAC air resistance. When closing, the system utilizes a combination of motor braking and physical spring force to guide the door leaf safely into its frame.

• Adjustable Last-Latch Small Spring: The internal chassis features a dedicated secondary mechanical adjustment screw. This allows installers to increase or decrease the closing force over the final 4 degrees of travel, ensuring the door safely overcomes latch-bolt friction to lock tight without slamming.

• Integrated Fire Alarm Interface: The onboard motherboard features a dedicated, normally-closed safety input designed to link directly to a building’s central fire alarm control panel. The moment a fire alarm breaks the circuit, the electrical drive safely steps down, allowing the pre-charged mechanical spring assembly to take full control.
