The LECTUS select reader reads data from contactless RFID credentials and sends the data to
a higher-level control center. This is where the evaluation takes place as to whether a
credential is authorized or not. The result is sent back to the reader, which then provides a
visual and an acoustic signal. Communication between the reader and the control center takes
place via an encrypted RS485 bus.
The reader has a compact design and is available in two variants, with and without a keyboard
(each as a flush-mount version). The flush-mounted variant fits into any device box in flush-
mounted or hollow-wall design according to DIN, with a device screw distance of 60 mm.
The readers have tamper monitoring and tear-off detection (i.e. a sabotage message is
generated if the reader is completely torn from the wall). They are suitable for both indoor and
outdoor use.
Connection type: 8-pin screw / plug-in terminal
