NEMEF 1739/36 Panic Lock E Function Universal Over 200kg High Security Fire Door

Product Overview

The NEMEF 1739/36 E-function panic lock is engineered for use in public buildings where doors are exposed to frequent damage, such as emergency exits and high-traffic passageways. It is approved for integration in fire-resistant and smoke-control door assemblies, contingent on positive evaluation, and capable of withstanding 200,000 test cycles under a latch load of 25N. Exceptionally high corrosion resistance ensures suitability for demanding environments.

Its most distinctive feature is the anti-panic "E" type mechanism: from the inside, exit is always possible using a handle or lever regardless of lock status; from the outside, entry is only via key. This functional configuration eliminates unauthorized opening risk while ensuring life safety, making it particularly suitable for bulk procurement in public sector and commercial construction projects where fire and safety compliance is mandatory.
