This is a Double End of Line resistor network. DEOL. Monitors 4 states of the device.
Normal Condition = 2K2
Alarm Condition = 6K9
Tamper Condition = Open Circuit
Tamper Condition = Short Circuit

So This Is Correct Hey..?... Best way to wire them up..? Coz someone told me that Pir's have a NO and NC closed contacts and i was like ...Eh ok.. But dont think they do..
Some devices can be either N/O or N/C, but most commonly in PIR's it's N/C.
