Siemens SK5 Manuel D’Utilisation

 

 

The security unit SK5 is used in high security areas. It prevents unauthorised 
persons from opening the electric release by connecting battery voltage to 
outgoing conductors.  

The SK5 is suitable to all SiPass Entro products, which is furnished with a tamper 
switch for external connection. E.g. Bewacard, Bewatel, Bewacom and Telecode. 

The security unit SK5 includes a relay that breaks the connection between the 
opening relay and the electric release when the housing for the card reader or door 
entry phone, is opened or removed from the wall. At the same time a buzzer is 
activated in the SK5.  

The unit is restored by the red button when the housing is closed again.
