I moved into a house fitted with a British Gas alarm with no manuals and no interest from British Gas despite several calls. I do however have the passcode. I have managed to identify the control panel as DSC LCD 5500(Z) and the circuit board in the cupboard says DSC VA00?. It all worked fine until the dispaly showed 'Main battery low' then the whole system went dead - no lights nothing. I have now replaced the battery but it's all dead, no lights nada. :cry:
Please can anyone advise how to bring it back to life? Are there any secret reset switches?
