Alarm Keypad Dead and Siren going off?

It's the battery in the Siren that is creating the noise because there is no power (it's called hold-off) being sent from the control panel mains supply or control panel battery (the one that is naff & causing all the problems)

There is nothing on the control panel, it is completely dead, both of them. If the system is unplugged the siren continues to go off which I then assumed the battery backup was working because it was still providing power to the system. There has not been any issue with the battery backup in the past. It is a GE System.

Can't help.

No information given about the control equipment, what is/isn't showing at the panel, power cut / no power cut etc etc

How did you test the battery to prove it is working well?
(It's not)

Charging voltage ?
Load Current ?
Discharge test ?
