How can I disable the Personal Attack button on my Paragon Plus alarm ?

My Paragon Plus alarm system which was installed by a previous owner has a remote Personal Attack button mounted in a small box on my bedroom wall which is active 24 hours a day regardless of whether the alarm is set or not. I want to remove the existing wallpaper and paint the walls of my bedroom but if I try to detach the Personal Attack button from the wall it sets off the alarm. Can anyone tell me how to temporarily disable the Personal Attack button to enable me to re-decorate the room.
