I just received a new SecuriLink 1200 yesterday and started installing today. So far I have three "issues". 1) The display is very difficult to read in anything but a dark room. 2) The RF sensitivity seems lower than the PS561 console it's replacing. I thought it would be a simple drop in replacement but several window sensors and remotes don't have the same range even with a PSX01 RF repeater within 50 feet. 3) I am still struggling with getting the SC1200 to work with my answering system. It works if I disconnect the answering system but with it connected the SC1200 ignores it's PIN even though the manual says otherwise. I may have to go back to the PS561 and a TR16A telephone transponder.
