Hello all, appreciate some help here, i have 4 pir sensors and a ADE Accenta Mini Gen4 panel, how should i wire the pir sensors in series? or should i wire each pir back to the panel? thanks for the advise!

Wire them all back separately, you will have more flexibility when programming then, If you wired them all in series then they will all have to be one circuit/zone type.

ok great so each pir will be in a separat zone if i wire each one separate?

yes.

It's best imho to have only a device per zone. This will then allow easy identification of the device that alarmed etc.

You will wire the circuit pair ie zone 2 to the alarm pair in the detector.

do i have to use the tamper wires? everywhere i read it says the alarm & tamper should be in series? or can i wire each tamper wire straight back to the panel

you do cable them back to the panel but they need to electrically be in series on a double pole global tamper panel.
