Logic 4 Alarm?

I have just moved into a house and it has a Logic 4 Alarm system. I have no instruction manual and don't even know if it works.
On the panel it has Zone 1 & 2, Tamper, Exit and mains.
In the kitchen there is a sensor that does flash and in one of the bedrooms there is a panic button, but I don't know if this works or where its connected to!
I'd like to get it working if possible and I understand its probably a quite old system. Can you help. Thanks
