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.
