The KNX transponder holder transponder holder TH22AxxKNX is an EIB/KNX recessed device on rectangular boxes with 2 or 3 modules and round, for detecting and controlling the presence of a customer or service staff in the room.

Technical highlights & Configuration

Core Features

The appliance is equipped with two physical ON/OFF inputs available for controlling the door open/closed contact or other signals (window contact, bathroom alarm pull, etc.). On the device there are two relays for controlling the door lock and for controlling the “courtesy light”, or freely configurable for other uses. The front of the transponder holder lights up if no card is present (blind location function), turns off if the card is valid and flashes for 3 seconds if access is not allowed. The validation of the card takes place by checking the following data: “system number”, if the code is consistent, the “date” field (if enabled) is checked to verify its validity (if expired). Then check the “password” with all the codes associated with it and enabled (time slots, customer code, service code). If all the conditions are met, the door is enabled and, if set, the courtesy light is switched on and the reading result is sent to the bus. Configuration via ETS.
