Rated 4 out of 5 by from Good but not accurate Sensor is well built with good features, but it is advertised online as IP21, but on the box it’s only IP20

Rated 5 out of 5 by from Sensor Excellent product, takes a few tweaks to get it perfect and then when it's set up it great. Used it in my bathroom to save kids finger marks and pulled marks on the wall.

Rated 1 out of 5 by from Unit does not work properly Excessively sensitive people walking on the floor above would set this off, inconsistent times it would stay on for i had to return to site to replace unit for a proper steinal unit not happy and would not recommend

Rated 3 out of 5 by from Quality but difficult to setup 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.

Is there a downloadable wiring diagram for this item.

Asked by: Petermc66

Is sensor distance adjustable?

Website states 1-8m detection range - is this adjustable, or only dependent on the environment/obstructions? Thanks in advance
