Perimeter breach resistance threshold


You have mentioned in the spec that a 2 feet 30 AWG wire or thicker should be used for the peremeter loop.
I’m assuming that the circuit monitors the resistance of each loop, and it assumes that a breach has occured if the resistance rises above certain level.

Since we’re designing a costum flex PCB for the peremeter, it would really help us undertsand what is the resistance threshold. (The Min and the Max values)

Please advice.

Nominal Operating Design Requirements for your Flex PCB are:

Closed circuit resistance < 10Ohms
Open circuit resistance > 100MegOhms to ground or to return trace.

These should be pretty easy to achieve with standard flex PCB processes. If you need further information let us know.
