Hi,

If you introduce wireless pir, maybe i can help to you.In cable pir, you know, you send signals to pir regularly and receive them with mcu.If you can not receive signals (Cable cut by an intruder) , mcu must activate alarm. If regular signals change a bit (An intruder is in front of Pir), mcu must activate alarm again.You can write program easily with ccs to pic
For further questions for cable pir, dont hesitate to write here.
