I have had this security system for many years. In addition to the PS561 security consol, I have 6 door/window sensors and 4 indoor motion detectors. Recently the consol has begun chiming 5 times for no apparent reason, no LEDs are lit on the console. Also when I try to set the alarm I get the rapid chiming normally indicative of an open window or door, but none are open and neaither are any of the LEDs lit on the console. I tried resetting the system several times to no avail. Any clues as to why this is hapopening?
