When it comes to the Contact Sensors for the Boundary system we do get asked about how close they need to be in order to function?
The system is being designed to to be compliant with British and European standards so the gap between the sensor contacts should be no more than 25m or 1”. Any further apart and the sensor may not function as intended or easily create a false alarm.
It is possible to mount the two parts on a curved, PVC style frame as the magnet can be mounted at a slight angle. As long as the gap between the two parts is less than 25mm then it will function absolutely fine.
