4-wire door station module for hands-free speech for optimal speech quality at the door, even from great distance or with high ambient noise. 

COLOUR:WHITE

The correct choice of station determines the quality and benefit of an Intercom system. The 4-wire door station module ET 661 was developed for use in doors and gates, as well as entry ways and internal security sluices. The design is matched to the Siedle Vario 6 series. Matching the Intercom module, a keypad module and camera modules are available. Thanks to these modules doors and gates, as well as entryand gateways, to which a speech connection is required, can be integrated in the Intercom system in an elegant, modern design. This way all advantages of the Intercom system can be used, e.g. call transfer into the telephone- or cellularnetwork and networking.
