You need to replace this with a 12v 7Ah battery. Now the keypad has gone dead you would be well advised to call in an alarm company to look at it as the faulty battery has done some serious damage.

It is probably just a fuse blown as the CS350 has about 5 fuses on the PCB. The keypad is quite seperate to the battery fuse so I would say that the battery is dead and the mains fuse has gone.
