sounds like your builders have damaged one of your cables for a temp measure open the control power down mains and battery and fit a wire link across the 24 hour tamper terminals and also another link between - and tr of the control power the control back up mains and battery and reset the control with your access code. this will get your system working again but remember you have disabled all tampers on the system get in touch with an alarm engineer and ask him to find the tamper fault most people with a little electrical knowledge could also find the fault for you let me know if this solved your problem paul84842005@yahoo.co.uk good luck
