Rated 3 out of 5 by from Not my best Screwfix purchase This PIR seems to work Ok but for me its early days so time will tell. It’s tricky to wire up due to a poor design and lack of space. The instructions use weird grammar but the procedure is obvious. The quoted range is 12 metres max. Maybe this is true on a cold winter’s day; the most I managed was 4 metres with an outside air temperature of 16 degrees Celsius. The minus points are 1 The Screwfix catalogue and their web site describe the body as being die cast aluminium, mine isn’t its polycarbonate. 2 If you intend to fix the base of this PIR to a flat surface or an internal corner there should be no problem, but if the intended site is an external corner of brick your chances of success are small, the fixing holes are much too near to the brick edge, a cracked brick is almost guaranteed, I didn’t even try but I made my own bracket instead. Whoever designed the supplied mounting bracket should be strongly encouraged to pursue a less challenging career.

Rated 5 out of 5 by from Works well Good sensor and handy being able to mount on the corner of a building so you get coverage from both angles.

Rated 2 out of 5 by from You get what you pay for. Unfortunately it was broken in the box and there were no more in stock. Overall it seemed cheaply made and the Chinese instructions were difficult to understand.

Rated 3 out of 5 by from Cheap, OK, could be better Of the three of these that I've bought two have broken LUX dials out of the box, and there is clearly some other failure during assembly in the factory. Entering lockdown I didnt bother taking it back. I just levered out the broken dial to gain access to the rheostat that it would normally turn, then just turned that with a small screwdriver to adjust it. Copy this at your own risk. By removing either of the dials it will have a very small compromise of the weatherproof-ness, IMO it is still safe in the rain.

Adjusting the sensor

How do you actually adjust the dusk to dawn and time on with this PIR, unable to download instructions from Screwfix site and nothing in the box.
Asked by: McClintock
Answered this myself but for others :- there is a plastic ring with 2 flat surfaces on that you use to rotate the sensor head with - hold the flat surfaces and pull down gently - there you will see the adjustment dials. Ensure the flat surfaces are at sort of 3 & 9 position.

Can I power 2 lamps from just one PIR

Asked by: Jonwai
If you have decent electrical knowledge then you will easily be able to switch up to the rated Wattage, this could be multiple lights.

Can this sensor also be mounted on a flat surface or is it just corner mount?

Asked by: dapeel
You can mount this unit to a flat surface. The rear angle face detaches allowing the back of the unit to screw flat against the wall. I have mine fitted this way!
