1.0  Shunt lock function 3066 System Components 
In objects protected by the alarm, measures must be taken to prevent any 
unintentional entry of the secured area when the alarm system is activated externally 
(burglar alarm system, BAS) because this would trigger a false alarm. The Shunt lock 
function 3066 implements such a feature without extensive work on the door or 
doorframe. 
The following components are needed for this:   
1.  Activation unit(s) (MA and SA)   
Such a unit is used to switch the alarm system. You need at least one 
activation unit (AU) to activate and deactivate the system externally. If you 
want 
to be able to activate/deactivate from several locations, you need the 
corresponding number of activation units. With a mouse click in the locking 
plan, you can issue the authorizations for activating and deactivating the alarm 
system. 
Basically, there is a difference between the master activation unit (MA) and 
the slave activation units (SA). The SAs are needed only if you want to 
activate/deactivate from more than one location. It is always the MA that 
activates/deactivates the alarm system externally over a floating contact. SAs 
only send the appropriate requests to the MA. You can also activate internally 
by using SAs that are separately connected to the internal activation 
connection of the burglar alarm center (BAC). 
2.  Deactivation units (DA)   
These are installed next to the doors of the secured area (and in the 
immediate vicinity of the digital cylinder). They make sure that even an 
authorized transponder cannot open these doors accidentally if the alarm 
system has been activated externally. This reliably prevents false alarms.
