into the system simply by tripping the device. (i.e. door or window); The 5800 series transmitters and V-Plex
®
Serial Poll
devices send unique serial numbers that are learned for that zone
• Limited Access: Some controls may be programmed to allow certain codes to only work during certain times. (*see also
