When used outdoors, the cylinder must be protected against sustained rainfall using a
weather guard.
NOTICE
Freezing liquids can disrupt the function, resulting in doors not opening. No water, therefore,
should get into the cylinder. When used externally, the cylinder must be protected against
sustained rainfall using a weather guard.
When used in fire protection doors, escape routes or rescue routes, the locally applicable
guidelines and building regulations must be observed.
NOTICE
Doors at risk of forced entry
• The following points must be observed for certification as per VdS Class B: On doors at
risk of forced entry, the 'Protected' version of the digital cylinder must be protected with
a VdS-recognised burglary-resistant Class B or C doorplate. These doorplates correspond
to DIN 18 257 Class ES 2 or ES 3 and EN1906 Class 3 or 4. The cylinder must protrude no
more than 3 mm beyond the doorplate.
• The user media (keys, badges, etc.) must always be kept safe to ensure only authorised
personnel may gain access. If identification media are lost, the authorisation data must
be blocked and deleted from all cylinders immediately.
NOTICE
Wrong type of lock
The asymmetrical digital cylinder is not permitted to be used in some lock types.
Please refer to the lock manufacturer’s instructions.
