DS-22 WFDK IP Weatherproof digital compact call station 

The DS-22 WFDK IP weatherproof digital compact call station is used in intercom systems
in the DS-22 decentralised communication system. It enables direct voice connections with other call stations and loudspeaker announcements outdoors and in rooms with harsh or noisy environments, e.g. in heavy industry operations or railway engineering areas.

The DS-22 WFDK IP weatherproof digital compact call station has 6 illuminated pushbuttons with 6 lines and is available in the housing colours pure orange RAL 2004 and golden yellow RAL 1004.

With a WFDK Add-On Housing connected, it is possible to add an additional 12 illuminated push-buttons with 12 additional lines to the DS-22 WFDK IP Weatherproof Digital Compact Call Station, per WFDK Add-On Housing connected. Up to four WFDK Add-On Housings can be connected to a DS-22 WFDK IP weatherproof digital compact call station. This allows a DS-22 WFDK IP weatherproof digital compact call station to be fully equipped with a maximum of 54 buttons.

The DS-22 WFDK IP weatherproof digital compact call station is connected to the DS-22 network via standard network cables. The standard power supply of the DS-22 WFDK IP weatherproof digital compact call station is PoE, a DC 48V power supply from the network node is optionally possible.

The DS-22 WFDK IP weatherproof digital compact call station already has an integrated 7W Class-D monitoring or announcement amplifier in 8Ω technology as standard.
