How do I diagnose a fault with my Securit 700L alarm?

My Securit 700L alarm is not engaging whenever I input the code. There is no light showing on the panel (usually a green light under "mains" indicator) and all PIR's are constantly showing a red LED. Does this by chance indicate that a new fuse or battery is reqired?? The fuse at the mains box is ok so I believe electricity is getting to it. Any help much appreciated

I've no idea how people manage to get through life with no thought process.
