ARRIBAUPHAUTCod. 9730034MAE-900GENERIC COVER FRAME3mmNote: See the ALCAD website at www.alcad.net for information on ordering the generic cover frame.TAP-OFFS AND SPLITTERSElements which make it possible to distribute the video signal from the video unit to the different dwellings in the installation.TAP-OFFS21Elements with several tapped outputs without loss for connection to monitors (1) and with 1through output for connection to the next tap-off (2) when the desired distribution of the signal isstar-shaped, installing one tap-off for each floor or ramification of the building.Tap-offs fall into two groups: those for coaxial cable and those for twisted pair. The choice oftap-off will depend on which type of cable is to be used in the installation to transmit the videosignal from the video unit.COAXIAL CABLE88 mmCod. 9730031 DIV-024COAXIAL VIDEO TAP-OFF, 4 OUTPUTS TO MONITORS57 mm24 mmTap-off with 4 tapped outputs without loss for connectionto monitors. Connection by means of screw terminals andclamps, 75 Ω coaxial cable (1). It incorporates a 75 Ωresistor for the closing of the video line (2); this should onlybe removed when using the through out-put of the tap-off.The tap-off only consumes energy when one of the monitorsconnected to its tap outputs is activated.Technical characteristics:Outputs4275 Ohm1ScrewterminalClampConnection of coaxial cableInternalconductorMeshOuput impedanceConnectionGainVideo input levelPower supplyBy means of screw terminalsand clamps11 Vpp ±0.25 (75 Ω)Through monitor (coaxial)47
