First of all i would like to thank everyone for this site. It has been real helpful
I am Homeowner, trying to install a DSC power 832 with an expander board and two keypads ( 5500, 5501Z).
I can not access either of the keypads--
the 5500 keypad never worked -- it just displays the time and "program" - the keys do not function on it -- therefore a keypad lockout.
the 5501Z keypad was working-- but my endeavor to fix the 5500, by trading locations, then movnig them back --
I somehow am locked out of this pad too the display shows 'Jan 00/00/0000' and "Keybus fault -- Call for service" and it beeps in 5 second intervals
Thanks in advance!!
