Function
The lever handle on handles with a reading field is only released if a
transponder with an appropriate authorisation (authorised transponder) is held
to the reading field. Data is transmitted inductively (via RFID) between the
transponder and the reading field by means of a coil that is present in the
reading field and in the transponder. Only one of the devices (reading field or
transponder) has to have a power supply to guarantee the function. In the
GUARD S family, power is supplied by the electronic han
dle’s battery.
The lever handle is connected to the lock via the spindle by means of a three-
part coupling. The outer half of the coupling is connected to the outer lever
handle. The inner half of the coupling is connected to the spindle hub and the
inner lever handle via the spindle. The halves of the coupling connect if an
authorised transponder is held to the reading field. This allows the door to be
opened with the outer lever handle.
Once the set coupling time (opening time) has elapsed, both halves of the
coupling are separated from one another again. An authorised transponder
must be held to the reading field once again to open the door.
You can adapt the system to different requirements with the different variants
of the GUARD S handles:
•
Slimline handles replace existing narrow handles with a width of up to
40 mm and screwing points above one another.
Slimline handles are particularly suitable for use on tubular frame doors.
•
Wideline handles replace existing handles with a width of up to 56 mm and
screwing points above one another.
Wideline handles are particularly suitable for renovating doors that are
damaged and show differences in colour due to old handles and round
rosettes.
Wideline rosettes are suitable for renovating round rosettes on the inside of
the door with adjacent screw connection points.
