Systems may be created with intercomconversation privacy to the loudspeaking unit.Several automatically switching entrance doors maybe catered for.1+nThe 1+n audio system was created to transforma traditional bell system into a complete door phonesystem without needing to add wires to the columnand ensuring conversation privacy between the variousapartments.Entry panel Electriclock5 wiresSigno 4+(n-4) Signo55Arco Arco4+n4+(n-2)5 5Utopia7+Coax7+CoaxSinthesi6+(n-1)+Coax6+n+Coax789/5B9+n+Coax2Video systemsAnalogue video systems derive from the 4+n and 1+naudio systems and may be split into two types:coax systems and 5-wire systems.Coax video systems4+n door phones with electronic call are usedin coax systems. A very high number of combinationsare possible, with both b/w and colour video door phones.The coax cable allows great distances between cameraand monitors and allows to create the same system typesas a 4+n audio system.5-wire systemsThe 5-wire system derives from the 1+n audio systemand is suitable for transforming 4+n audio systemsinto video systems without adding a coax or other wiresin the riser column.Video powersupply unitSinthesi8+nElectriclock2The audio/video analogue systems are suitable for smallto medium sized installations because one wire is neededin the riser column for each call.• 49
