Hi guys I'm having my house pointed and have 2 active wireless bell boxes to remove, the engineer says disconnect the battery but once they are unscrewed from the wall the alarm will go off so I have to lay them on their back and put a decent weight on top as they have a pressure device (anti) tamper) that goes against the wall then I have to put in my 4 digit code and press NO so that's OK for the removal does anyone know how to refit the boxes I suppose it's just fasten them back to the wall and they will start to go off so once secure put in your 4 digit code maybe with YES at the end, me email is REMOVED if anyone can advise further, thanks
