Door communication DCS btn I/F 2-g [121000] DCS push button interface, 2-gang Gira system devices Features: - The DCS button interface, 2-gang is used to implement a zero-voltage button signal on the Gira door communication bus. - The DCS button interface features two separate inputs for the connection of zero-voltage buttons. - The inputs can either be used to trigger a switching action (e.g. switching lights) via a switching actuator or flush-mounted switching actuator, or they can be assigned to a home station. - The DCS button interface is intended for installation in a device box behind a conventional button. Technical data: Power supply: via the 2-wire bus Ambient temperature: -5 °C to +50 °C Notes: - The button is connected using a 3-wire, approx. 20 cm long connection cable. This connection cable can be extended to a maximum of 5 m. - When the button interface is assigned to a home station, the two inputs function differently:Input 1triggers a floor call. This input is required when only a 2-wire line is available to connect a home station incl. floor-call button (e.g. when retrofitting an existing door station).Input 2triggers a door call. This input is required if the automatic door opener for the home station is to be triggered using a mechanical button.
