NEMEF 1769/46 Panic Lock Anti-Panic D Function Split Follower Left Security Class 6

Product Overview

The NEMEF 1769/46 72/65/24/9 is a left-handed panic lock engineered for use on fire-resistant and smoke-control door assemblies, subject to approved evaluation. Specifically designed for heavy-duty applications, it withstands intensive usage and frequent impacts, making it well-suited for high-traffic public buildings such as schools, hospitals, and offices. Certified for 200,000 test cycles at a 25N latch force, and operational from -20°C to +80°C, it provides a high security rating of 6 (scale 1 to 7) and is compatible with doors weighing over 200 kg.

The defining feature is its D-type anti-panic function with split follower: users can always exit from the inside via handle or lever, regardless of lock status, while outside access is controlled per key operation. This eliminates compliance risks in escape route projects and simplifies planning for facility managers who must guarantee unblocked egress routes. Particularly suited for fire safety door schedules and bulk procurement for public sector facilities requiring both security and emergency escape provisions.
