Cheers, yeah I've got a few things to go at now. The sensors don't have a sensitivity feature so that's out the window, but yeah I'll try a few of these things, n any more suggestions. Many Thanks

Its very unlikely the alarm is doing something to trigger the occupancy sensor.

 

Mask your sensor(s) over with electrical tape, open door external *IF* there's a weird interconnection between the systems your lights will come on.

 

Exactly, isolate things to narrow the problem down.

" I installed this in an understairs toilet. The unit fitted into a 63mm hole and is a 3 wire installation ( L N SwL ) It is suitable for switching LEDs as it has a built in relay.
I had major problems setting the sensitivity because this is a Microwave sensor which can 'see' through materials and it was switching when people walked across the landing! but when the 'sens' was reduced enough, to stop this, detection in the WC was less reliable. The unit can only be adjusted when de mounted which is a bit of a pain but stops 'fiddlers' and looks better.
I plan on returning this for replacement in case this is a rogue unit when Screwfix have them back in stock. "

 

 

Possibly right with microwave then, should have some sort of adjustment I would expect.

Lux n time adjustment. No sensitivity on this. 40mm hole for the sensor. Looks neat, n I have installed this type many times before no problems in the past

We have a microwave sensor in the shower upstairs. With no sense of irony it comes on whenever we use the actual microwave in the room below...
