Four Steps to Eliminate RFI

  1. Instead of changing the detector with an identical PIR, go through our ‘PIR fault finding checklist’ to prove the cause is RFI
  2. Swap the troublesome PIR with another in the same building
  3. Fit an ACT 1376 PIR stabiliser inside the troublesome zone PIR and put the circuit on a soak-test
  4. If a false alarm moves to the other zone, change the PIR and recover the PIR
