Hafele WT 400 Betriebsanleitung Seite 70

Installation in a Siedle intercom is also possible in combination with Siedle blind module
BM 611-0 (to be provided on site by the customer). The cover of the WRU 410 is not required
in this case. Signalling by LEDs (red/green) is no longer visible with this installation variant.
The access control system can be extended to include other WRU 400 / WRU 410 readers
at any time.
With the WTX 200 extension board and the WTX 201 8-way relay module, two optional
modules are available to expand the connection options of the controller.
