Resideo's VistaKey Single Door Access Control system is incredibly easy to install and configure. Designed to provide low-cost access control expansion for the popular VISTA-32FB, 128BP, 128FBP, 250BP or 250FBP Integration Ready Control Panels, the state-of-the-art module maximizes security investments by integrating access control, intrusion detection and fire detection into one system. Installation costs are reduced by eliminating the need to install additional wiring, panels and software. VistaKey communicates with the control panel on a standard two-wire V-Plex polling loop. Access validation time is minimized through Resideo's patented Global Polling feature and special V-Plex protocol. Installation time is reduced through automatic enrollment and quick-start test functions. All programming can be accomplished locally by a keypad or remotely using Resideo's Compass Downloader software. Specific system events can be reported to the central station via Resideo's Contact ID.
