The DS-22 WFD IP weatherproof digital call station is used in intercom systems in the DS-22 decentralised communication system. It enables direct speech connections with other call stations and loudspeaker announcements outdoors and in rooms with a rough or noisy environment, e.g. in factories in heavy industry or in areas of railway engineering.
In the DS-22 decentralised communication system, two variants of the DS-22 WFD IP weatherproof digital call station are available with a dial keypad. Alternatively, the 12 keys of the dial keypad in the DS-22 system can be used as freely configurable line keys, but without optical indication.
With its integrated DR-Intercom and crossing barrier station functions, the DS-22 WFD IP weatherproof digital call station is ideally suited for use in railway applications. These functions facilitate communication between railway operators and enable communication between road users and railway operators of manually controlled level crossings.
The DS-22 WFD IP weatherproof digital call stations described here have one to three double- toggle buttons for up to six lines, or two double-toggle buttons (two lines and two buttons for dialling control) and dialling keypad, and are available in the housing colour pure orange RAL 2004.
With a WFD Add-on housing connected, it is possible to expand the DS-22 WFD IP weatherproof digital call station by an additional 5 double toggle buttons with 10 additional lines, per WFD Add-on housing connected. Up to 4 WFD Add-on housings can be connected to a DS-22 WFD IP weatherproof digital call station. This allows a DS-22 WFD IP weatherproof digital call station to be fully equipped with a maximum of 46 buttons.
The DS-22 WFD IP weatherproof digital call station is connected to the DS-22 network via standard network cables. The standard power supply of the DS-22 WFD IP call station is PoE, a DC 48V power supply from the network node is optionally possible.
The DS-22 WFD IP call station already has an integrated 7W D-class monitoring or paging amplifier in 8Ω technology as standard, and in addition, depending on the delivery variant, partly already has an integrated 30W D-class additional amplifier in 100V technology. Call stations which do not have an integrated 30W Class-D additional amplifier at delivery are prepared for built-in and connection of a 30W Class-D additional amplifier with the L.-No. 221 6001 666 0, see accessories.
Call stations which do not have an integrated 30W Class-D additional amplifier at delivery are prepared for built-in and connection of a 30W Class-D additional amplifier with the L.-No. 221 6001 666 0, see accessories. Here, however, the connection type must be urgently considered, see Installation. Both additional amplifiers can operate a local loudspeaker circuit (LC).
