Adding existing lights to PIR Sensor

[Maccers-78]

Hello! I have existing garden lights at the front of my house, they are run from the RCD side of my fuse board on a single breaker unit of their own.
There are 4 existing lights that are wired in series, ie cable goes to one, then the next and so on.
I am looking at getting a PIR sensor only and using it on these lights.
I'd like the ability to still turn them on and off manually like I have always done with the switch located near the fuse board, in the under stairs cupboard.
I know some PIR's have the on/off/on thing but I want to avoid this and use a switch method, for example a double switch where switch 1 turns the lights on and off as they always did and then switch 2 only turn the PIR on for night time security etc.
Is this possible?

Using two single pole switches to provide overrides for a basic PIR

Thanks for swift reply! So am assuming the green line is earth? Also, the purple cable switched live I would connect to the existing cablings live supply that drives all the lights currently?

Yes Green is Earth, even if the lamp / PIR does not require an earth there must be an effective earth in the cables.

The Switched Live connects to the Live of the lamps.

Ensure that the PIR can switch the total load ( wattage ) of the lamps.

I would recommend the Steinel IS 180 PIR sensor, expensive but very reliable.

No. Parallel.

Erm, yeah, I guess so. I meant they are connected one after the next, sorry wrong terminology. If one bulb goes out the others down the line still work...
