synchronised wiring of a domestic home

[EddieB]

Hi Guys
A friend of mine's neighbour has just had a rewire of his house and every night his outside light comes on every few minutes and flashes on and off, she has asked him to sort it out and he says it'll be difficult as it's a "synchronised"system that's controlled from a device in the loft..... I've never heard of this has anybody else??

Sounds like some sort of timer/PIR/sensor mash up.

I wonder if it is an LED cctv which has a DVR in the loft. If the LED is not set correctly at the DVR it will flash on and off.

It could also be as simple as a loose connection!!

Whether it's a fault, done by design or something interfering with it, it can be and will need to be sorted before the neighbours complain to the Local Authority.
Artificial light nuisance is covered in the Environmental Protection Act.

I have heard of synchronised, swimming, dancing, diving and lots of other things, but synchronised wiring is a new one on me. ?

Did the new light come with the rewire?
Maybe they have Bats or other nocturnal intruders.

Funny you should say that, a local Barn Owl sits on top of a trees we had topped in the garden and learnt how to trigger the PIR and turn on the outside lights, this attracts the Moths, which in turn attract the Bats and that is what the Barn Owl feeds on, fascinating how they adapt to the local environment, we have since moved the PIR, poor thing must be getting hungry by now.?

I had one where a cat would trigger one on a flat roof below a light to keep it warm in the winter , when the light went off it moved again.
