I have an alarm system on my house and although its about 15 years of age still works fine .I have recently changed over the 12 volt battery in the panel but have come up against problms with the bell box battery.You can get replacement batteries for it but at a cost of £10-£12 i was wondering whether it would make economic sense just to replace the complete box.Trouble is the usual bell box has some puny 115db sounder.The point is COULD i upgrade the sounder to a 12 volt air raid siren / police 2 tone type sounder or would this be impractable and/or unsociable and COULD it be done.The panel i have is an Advantage ZX6 which i think is manufactured by A1 security ? Any input would be helpful and how easy are they to fit ? I am reasonably competent with wiring
