I’m fitting a wireless (enforcer) system to a house that has various styles of Upvc windows and doors.
I have bought shock sensors for the windows. The sensors also have a reed switch function that I’d like to use on some of the windows.
The problem I have is that some of the window frame profiles are chamfered and it’s difficult to get switch and magnet close together. I fitted a door contact on the french windows by mounting the sensor overhanging the chamfer.
The trouble is some of the windows have larger chamfers.
What is the biggest gap I can leave between switch and the magnet.
What do the pros do when faced with this problem?
