Im wiring up all my window and door contacts. Ive got the 3/8 stubby contacts with rare earth magnets so that I can hide all my sensors. The gap between my front door and the top sill seems to be to large for these sensors to work properly. I cant put them in the jamps because the doors have side lights (windows) attached to the door. Ive noticed that my parents alarm has a ball and plunger type trigger. Is there anything like this available, or anyone have a better solution?
