The lever handle on handles with a reading field is only released if a
transponder with corresponding authorisation (authorised transponder) is held
to the reading field. The data transfer (RFID) between the transponder and the
reading field occurs inductively via a coil which is present in the reading field
and the transponder. Only one of the devices (reading field or transponder)
has to have a power supply to guarantee function. In GUARD family products
this power supply is in the battery of the electronic handle.
The lever handle is connected with the lock via the spindle through 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 are connected if
an authorised transponder is held to the reading field. The door can be
opened with the outer lever handle in this way.
Following completion of the set coupling time (opening time) both halves of the
coupling are separated from one another again. It is necessary to hold an
authorised transponder 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 handles:
• Slimline handles replace narrow handles which are present with a width up
to 40 mm and screwing points above one another.
Slimline handles are particularly suitable for use on tubular frame doors.
Slimline rosettes are suitable for the renovation of oval rosettes.
• Wideline handles replace handles which are present with a width up to
56 mm and screwing points above one another. Compact Wideline handles
replace existing round rosettes.
Wideline handles are particularly suitable for the renovation of doors with
damage and differences in colour due to old handles and round rosettes.
Wideline rosettes are suitable for the renovation of round rosettes.
