Hi All
had a question, bought a house with DSC Classic PC1565 alarm bla bla bla
Previous owners gave me only code they knew which i assume is the master code. So i enter the process to change the master code pressing
*5[master code]40[new code]#
and it worked but the odd thing is the old code still works.
so if i enter my new code that works and also the old owner code works to(not ideal obviously)
So would it be safe to assume that the old owner code could be the installer code ?
if not then can anyone think why i can enter my code and the old code ?
i am very sure my new code is the master code as it is the onyl one that can be used to change system time and other things which it does whereas the older code doesnt.
any help?
should i perform a factory reset - is this hard ?
cheers
Dom
