The invention relates to, among others, a communication station (10) for an intercom network (11), comprising a plurality of operating elements (15a, 15b, 15c, 15d) each of which are configured in the manner of a lever (49a, 49b, 49c, 49d, 49e, 49f, 49g, 49h, 49i, 49j), wherein a lever starting from an inactive middle position (39a) is manually shiftable in a first direction (31) into a first switching position (39b) or alternatively shiftable in a second direction (32) contrary to the first into a second switching position (39c), wherein the lever is biased toward its middle position. The special feature of the invention consists, among others, in that the lever comprises a rotatably mounted adjustment element (59, 59a, 59b, 59c, 59d, 59e, 59f, 59g, 59h, 59i, 59j) for changing a parameter.

The invention relates to, among others, an intercom network (10), comprising a plurality of speech stations (11a, 11b, 11c) and at least one switching center (13, 16), wherein from each speech station connected to the switching center a connecting line (12a, 12b, 12c) extend to the switching center, wherein the connecting line provides a direct connection, respectively, between the switching center and the connected speech station, and wherein the speech stations of the intercom network, due to an audio data communication via the switching center, can enter into audio communication in real time. The particular feature consists, among others, in that at least one speech station (11a) comprises a terminal (53, 54) for a second connecting line (50, 50a, 50b, 50c), via which the speech station is connected with the same switching center (13) or with another switching center (16).

This disclosure describes an electronic device that can be installed within an access control system in parallel with a legacy interface device. The electronic device may perform steps of determining a set of configuration settings associated with an access control system to which the electronic device is electrically connected, receiving, by the electronic device, a first signal in a format associated with the access control system, configuring, based on the set of configuration settings, one or more signal pathways within the electronic device, generating, by routing the first signal through the one or more signal pathways, a second signal in a second format, and providing the second signal to at least one second electronic device.

The invention relates, inter alia, to a speech station (10) for an intercom network (11), comprising an in particular parallepipedal housing (12), with a housing front (13) and a rear housing side (14), wherein a plurality of programmable operator controls (15a, 15b, 15c, 15d) and multiple displays (16a, 16b, 16c, 16d) are tightly packed on the housing front (13), wherein the operator controls comprise a plurality of selector keys (17a, 17b, 17c, 17d), wherein the speech station as a result of a selector key being actuated by an operator provides a direct listen and/or talk connection to a selected other speech station (18a, 18b) of the intercom network via a switching station (19), wherein a plurality of connectors (20a, 20b, 20c, 20d), such as power-supply connector, data cable connector, BNC connector, are mounted on the rear housing side (14), wherein at least one loudspeaker (24a, 24b) is fixed on the speech station, wherein the loudspeaker is accommodated in a seat (25) between the housing front (13) and rear housing side (14), offset to the rear (26) relative to the housing front (13), and wherein the loudspeaker (24a, 24b) has a sound exit surface (27) from which the sound is propagated to an opening (28) in the housing front (13), wherein the opening has an opening cross-section (29) that amounts to only a fraction of the sound exit surface (27).
