The H4.27 Monitor is equipped with Two Input connection ports which allows a user to connect two door stations
or one door station and one CCTV Camera directly. It is required that this monitor be menu set as Monitor #1 (Default).
Door station control is automatic. eg., when any Monitor activates the door unlock function, only the door latch
connected to the operating door station will be unlocked. H424 does not suport 2 Inputs. See MDS for other options.
