    Wiring PIR sensors looping in and out.

    Should I be having problems with PIR security lights that are wired as a radial looping in and out from each light? I have 3 in a radial controlled via a switch but having problems getting them to work right. Any ideas? Is it because they are all linked? Back feed etc?
