Electronic Alarms and Home Security Devices - Dsc 1550pkrz & pc580

I have a DSC System with a PC580 Control Panel and Three DSC PC1555RKZ.

The panel has been powered down for three or four years- When we moved in we didn't want to deal with it. I decided to plug it in today.

The problem is we don't know any of the codes for it.
I tried the default installer codes, entering *8 then each one of these 1234, 5555, 6321, 1182, 1676, 1626, 5010, 1555, 5020, 9010, 1500, 1550. None of them work.

I read somewhere else that if you hear clicking when you power up the panel that means there is a installer lockout. How do I get around this?

I believe the installer was Adelphia (as there is an adelphia sign outside) I also think the previous owner had the monitoring with DEVCON.

So my question is... What do I do to reset the codes so I can use the system. I don't want to set up monitoring. Eventually I would program it to dial my cell phone or something of the nature.

Thanks.

In short, short of a lucky guess at the installer code, you don't.

There is no bypass for an installer lockout on a power series panel. All you can do is replace the motherboard.

Any recommendations for a replacement? Should I get the same one?

Would this work?

Thanks!. I'm a computer technician and Home Theater installer. I just don't know enough information about alarms to know what is compatible with the keypads and system is already installed.

The 1616 _should_ be compatible with your existing keypads (check the installer manual to be sure).

Does anybody know any of the installer codes DEVCON or Adelphia would use?
