• oldest 1980s (?) PIRs: What is the pinouts for thises units? Answer from Eppley:

It depends on the age of the PIR as the 6 pin connectors were used before the dome thermistors were included standard and then we switched to the 10 pins. However, certain customers continued to request the 6 pin in some cases. The wiring of the 6 pin PIR is probably:

A: Thermopile (-) black B: Thermopile (+) red C: Case Thermistor white D: Case Thermistor green E: Instrument Ground or Dome Thermistor brown F: not used or Dome Thermistor blue
