Lock Cylinder-D&D Hardware

1. Category of use


One category is identified.

 

Grade 1: For use by people with a high incentive to exercise care and with a small chance of mis-use. 



2. Durability


Three grades are identified according to the number of test cycles achieved.

 

Grade 4 : 25 000 Cycles


Grade 5 : 50 000 Cycles


Grade 6 : 100000 Cycles

 


3. Door mass


One grade is identified:


Grade 0 : No requirement



4. Fire resistance


Two grades are identified:


Grade 0 : Not suitable for fire/smoke resistant door assemblies


Grade 1 : Suitable for fire/smoke resistant door assemblies subject to satisfactory assessment of the contribution of the cylinder to the fire resistance of the specified fire/smoke door assemblies. Such assessment is beyond the scope of this European standard (see EN 1634-1).box 4), it must be possible to demonstrate compliance with the Essential Requirements of the Construction Products(Amendments)Regulations.



5. Safety


One grade is identified:


Grade 0 : No requirement



6. Corrosion and Temperature Resistance


Four grades are identified according to EN 1670:


Grade 0 : No corrosion or temperature resistance requirements


Grade A : BS EN 1670 Grade 3 corrosion resistance (96 hours NSS): no temperature resistance requirements


Grade B :No corrosion resistance: resistance to -20/+80 C temperature extremes


Grade C :BS EN 1670 Grade 3 corrision resistance: resistance to -20/+80C temperature extremes


No distinction is made between the inside and the outside of either the cylinder and/or the door. On completion of the test, the cylinder must operate.

Keyed To differ

Cylinders to differ are all operated by individual keys all different to each other



Keyed Alike Suites(KA)

In keyed alike arrangements all cylinders are operated by the same key. This gives an arrangement where one key will open a group of locks. Not to be confused with a master keyed suite (see below). Cylinders can also be keyed alike to the euro profile, oval and rim cylinders. This is useful where a combination of cylinder mortice lock cases and cylinder rim nightlatches are being used.


Common Entrance Suite

Common entrance (or flat enterance) suites are designed to enable a tenant to use the same key for his own private doors as well as doors common to other residents within the same buildings. The common to other residents within any master key suite.

Grand Mater Key Suites(GMK)

Grand master key suites are used when it is necessary to have more than one master key group. These groups are referred to as sub suites.In these instances all cylinders irrespective of their sub suite, are controlled byone key as the grand master key.
