5.5 Connecting the comfort handle
5.5.1 Connection to Access Control
The Access Control supplies the comfort handle with
the necessary operating voltage via the connection
cable. A separate power supply unit does not need to
be connected.
◾ First disconnect the CAN bus from the Access Con-
trol.
◾ Fit the handle to the door to be monitored (see sec-
tion5.4 "Installation procedure").
◾ Connect the handle via the connection cable to the
Access Control.
◾ Connect a reader unit to the Access Control with the
connection cable.
◾ Connect the CAN bus to the Access Control again.
5.5.2 Connection to external controller
Opening the comfort handle may alternatively be con-
trolled without an Access Control, connected coded
lock or transponder reader. In such cases, the required
voltage supply and the signal for opening the handle
lever must be provided by the external controller via the
PLC interface.
◾ For this purpose, please note the pin assignment of
the RJ12 connector on the comfort handle connec-
tion cable.
