5.1.2 Requirements for all classes
5.1.2.1 HSL shall only be opened by valid opening codes. The opening code(s) shall be retained as the
only valid opening code(s) until deliberately reset. Overlaying or undocumented code(s) are not
permitted.5.1.2.2 Where mnemonic codes are used with a HSL these shall be able to be changed.
5.1.2.3 Any supplementary device (e.g. micro switch) which is fitted by the HSL manufacturer shall not
be capable of being used to obtain information about the code.5.1.2.4 An input unit is a necessary part of a mnemonic and electronic HSL although one input unit may
operate more than one processing unit.All HSL shall have a processing unit to validate the correct code. Each HSL shall also incorporate a
blocking feature or be capable of causing movement of a blocking feature. If this feature shall be activated
before first use a note to this effect is to be included in the instructions for the use of the lock
5.1.2.5 If the blocking feature is not moved manually there shall be a means of indicating whether the
HSL is in secured HSL condition. If the HSL does not fulfil the requirement by itself automatically and the
secure and locked condition can solely be checked by trying to turn the handle of the boltwork of the
secure storage unit, then specific requirements shall be included in the installation instructions as well
as in the operating instructions (according to Annex A).5.1.2.6 An opening code shall not be capable of being altered or being changed other than by a recognized
code.5.1.3 Class D HSL
5.1.3.1 Means shall be provided by which the locking status, locked or unlocked, is made obvious.
5.1.3.2 A mechanical combination HSL shall be in a scrambled condition after locking.
5.1.3.3 A class D HSL shall contain a device which indicates the scrambled condition.
5.1.4 Mechanical key operated HSL5.1.4.1 For all mechanical key operated HSL (see Clause 4), the same codes for the key sets shall not be
repeated until 100 % of the usable codes have been used. If a manufacturer has more than one
manufacturing plant the requirement is to be applied per plant. No synchronization between the plants
is needed. However multiple manufacturing plants shall not start at the same code at the same time.
5.1.4.2 Codes (and sets of code tokens) shall be chosen at random.5.1.4.3 There shall be no number or marking on either token or HSL which identifies the code. Also no
legitimization card shall be issued.5.1.4.4 It shall not be possible to remove the key from a HSL whilst that HSL is in the open position except
for code changing. This requirement is applicable to all classes. Note that it is acceptable for this feature
to be activated immediately prior to the first use of the HSL.5.1.4.5 The key shall not break under the applied maximum torque of 2,5 Nm. The test is to be conducted
according to 8.2.1.4.5.1.4.6 In addition to the foregoing requirements the manufacturer is also to complete the declaration
