Hi All. Recently moved to a new house with existing melcom 4500 security system. Where can I fine the manual or pin number? I changed the battery and it kept alarming. Thank you in advance.

moving house, company who installed out of business. what proceedure do I use to disarm system, want to take alarm with me to new home. when I put in 9999 and unscrew cover alarm goes off

Zone 3 will not reset even after following the instructions. Until it resets i cannot arm the alarm.
