PIR controlled led floodlights

[polo1]

Does anyone know why manufacturer's instructions would state not to have more than one fitting on the circuit? These are customer supplied "frog eye" external floodlights, each fitting has 2, 20W eyes.
We weren't aware of this instruction and fitted the two fittings on one radial, the second fitting looped from the first. The second fitting only works/ detects movement intermittently, and I was wondering if this was related to the m/f insts...but I can't think why wiring the way we have would be an issue?
Any thoughts?
Cheers.

The only thing I can think of is if the PIR switching generates interference on the supply that may trigger or otherwise damage another PIR sensor.
However this is a major design flaw in the lights if this is the case and having a separate circuit instruction would indicate a lack of competence in manufacture to me.
I might suppose that you just have a faulty second sensor.

Thanks Richard. I just can't think why two fittings on one circuit would be problematic; it's going to be a ball-ache to runs separate circuit

Fit something decent and get customer to return the tat they have bought?
