1.0 Functional Description
1.1 General Information
In objects protected by the alarm, measures must be taken to prevent any
unintentional entry of the secured area when the alarm system (burglar alarm system,
BAS) is activated externally, because this would trigger a false alarm. The Shunt Lock
function 3066 implements such a feature without requiring 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. You can use a mouse click to issue
the authorizations for activating and deactivating the alarm system in the
locking plan.
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 or deactivate
from more than one location. It is always the MA that activates or deactivates the
alarm system externally using 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 see to it that these doors
cannot be accidentally opened even with an authorized transponder if the
alarm system has been activated externally. This reliably prevents false
alarms.
