NEMEF 1769/46 Panic Lock Function D Split Follower Right Fire Door Security 6

Product Overview

The NEMEF 1769/46 panic lock with function D is designed for use on fire-rated and smoke-control door assemblies in public buildings such as schools, hospitals, and office complexes. Engineered for high-traffic environments where doors are subjected to frequent impact and use, this lock is rated for doors weighing over 200 kg and certified for 200,000 cycle endurance at 25N latch loading. It provides a high level of corrosion resistance, performing reliably from -20°C to +80°C, and features security rating 6 on a 1?7 scale.

The distinctive feature of this SKU is its function D anti-panic mechanism with split follower (orzech dzielony), allowing always-enabled emergency exit from the inside via lever or handle, regardless of lock status. This significantly reduces risk for facility managers and specifiers tasked with meeting stringent safety and accessibility codes, while enabling flexible access control solutions for public environments. Particularly recommended for bulk procurement and projects in public sector facilities requiring certified fire and smoke protection hardware.
