7. You can also optionally use an activation unit without antenna extender.
Install it as described in Chapter 4.2.
In order to guarantee that the system can be
externally activated from the
outside only, you must then install a
button in the outside area. You cannot
externally activate or deactivate the system by operating a transponder until
this button is pushed.
The deactivation acknowledgement input (pin 13) is suppressed on master
activation units (MAs) as long as it is connected to ground (normally closed
button in outside area).
A Schottky diode decouples the deactivation acknowledgement line (see
below). This diode is needed, however, only if there are slave activation units.
With slave activation units (SAs), you can apply the activation suppression
(pin 12) to ground over a normally-closed button that is in the outside area. If
there is also an activation suppression button on the master, you should use a
circuit according to the figure below.
