ohh thanks for the above remind the smoke alarm is just two years old I ruled it out in the first place

sorry to put the wrong title, it's optima 2 plus system

Not sure if it's the right place We moved into our house 2 years ago. It has an old active alarm system which we have never used (lights on main box alight as well as those on the room sensors). We are renovating the house and will be needing to remove the system. From yesterday it starts to beep Intermittently every 30 seconds. it's optima 2 plus alarm I found the engineer code and had looked at the manual after hours' effort resetting it still couldn't silent the beep. It doesn't quite mention such case and how-to in the manual. Can anyone adivse thanks!
