Two Pir In One Zone (Fsl)

[ask121]

I have a cooper security 9651 panel. I'm rewiring the panel from global tamper to FSL because i've been told its more secure. I've wired single PIR zones with no trouble but when there is more than one PIR or surface contact or Panic button it shows tamper in walk test. If I one device is open at once in a zone, its fine but if I open two or more devices in one zone, the panel detects tamper. (E.g. When I open one door in Zone 7, the panel doesn't say tamper but when I open a door and a window in Zone 7 the panel will detect tamper)

 

Can someone help me with this problem?

 

Thanks

You shouldn't have more than one device per circuit.
Eol Is only more secure if the cable is attacked.
