1. Doing things properly
2. The real advantage of have a tamper associated to a zone helps you identify issues, or if while the system is unset someone interferes with the system.
Having a global tamper is better than no tamper notification, but one that's associated with a zone, may identify the front cover is not on correctly for that device, or the back tamper indicate that the pir is not correctly positioned in its housing.
If the PIR is not correctly seated and the housing correctly closed/ sealed it can affect the PIR's functionality but it also encourage certain insects/ spiders to take residence in the device.
As for rewiring, you will need to move 1 wire at the PIR end if its wired correctly at the panel, select the resistors, keypad or expander and change the wiring type.
opening the PIR, moving the wire and selecting the jumpers, reprogram the wiring type, a few minutes at the most.
To be honest I think its barking you have certain security issues addressed in the extreme and then ignore the basics of doing thigs right.
No point in having a premier panel tobe honest if you aren't going to use it properly???
