High-security doors

A meeting between locking expertise and door manufacturing expertise


In order to guarantee heightened security and compliance with the requirements of the standards concerning public access to buildings, for hotels and even for hospitals, we have combined our expertise in mechanical and electronic locks with a number of French-based door manufacturers.

Accordingly our products, as mechanical monopoint locks, motorized monopoint or multipoint locks, electronic cylinder locks and standalone pass readers installed on doors, have successfully passed the various tests of compliance carried out primarily in CNPP test laboratories (Centre National de Prévention et de Protection).

RC4 - RC5 testing pursuant to EN 1627-1630

In order to optimize security measures in the face of various threats (vandalism, theft, terrorism) to at-risk or sensitive sites, we have developed a range of multipoint mechanical or motorized locks which, when integrated into an armored door assembly, offer a minimum resistance of 15 minutes to attacks on the bolts, the cylinder lock, the hinges and manholes (cutting a hole in the door leaf).

The LSS range of multipoint locks, adjustable from 2 to 9 closure points, has successfully passed the tests carried out by the CNPP for a total testing time determined in accordance with the grades in the standard, thus achieving RC4 - RC5 certifications under the EN 1627-1630 standard.

Lever handle test

For sites where the security needs are at a maximum level, we have developed mechanical and electrical locks which are resistant to the most extreme tests.

In fact, a 600 kg ram launched at a speed of 3 meters per second struck the lock fitted to a solid or metal grille door. To achieve this validation, the door must withstand 30 blows with the ram.

Fire door test

To satisfy the requirements of the fire regulations, internal doors in buildings must have specific fire-resistant properties, to protect people and assets.
This resistance applies to the door assembly as a whole, i.e. to the door but also to the door locking device.

Accordingly, the door assembly is placed in front of a furnace in order to expose it to a raised temperature, and the elements tested should be fire-resistant for a specified period, depending on the classification level.

Thus our range of LSS multipoint locks, our range of Narrow Fit readers designed for the hotel sector and our Optimal Lock electronic cylinder lock (and others) have all passed these fire tests, offering up to 120 minutes of fire resistance.
