Panic function E (latch lever function)

In case of the most common panic function (latch lever function), only authorised people can access the door by means of a key.
Similar to house entrance doors with fixed knob or push/pull handle on the outside.
Thus the latch can be retracted by means of an authorised key only. Afterwards the door can be pulled open via knob or push/pull handle. This wil ensure, that only authorised people are able to pass the door from the outside to the inside.
Typically this panic function is often used on exterior doors.
