Hello there, sorry, homeowner with very little experience of security systems here so please excuse my stupid question! I was wondering whether I could get an opinion on an Accenta G4 alarm and its probable state of activation. I moved into a flat fittend with an Accenta Mini GEN4 with LCD Keypad system with infrared sensors. The system was not used by the previous owners, so has been unused for at least six years now - I was never given any codes. In that time none of the batteries have been changed. The alarm has never gone off. None of the LCD on either the main panel or the remote keypad have ever been lit. At a recent power failure, there was no sound either of alarm or of beeping from the panels either. Could you tell me whether I can conclude from this that the system is completely offline, and for example removal of any of the infrared sensors and cutting the cables will not result in a tamper alarm? Or do I need to call a specialist to take the system completely offline before I can do this? And IF I were to cut one of the cables (one of the sensors is very much in the way of a renovation project), and it DOES go off, would cutting the main power line to the outside siren/sounder box shut it off again? Thanks a lot, all help very much appreciated!
