Hi,
I,m Alan, new to this forum, but it's been very helpful in the past with good information.
I've got an outside light that has a photcell for day/night and a PIR that works at night. I now want to disable the PIR so
that the light comes on at night and stays on. The unit does have an overide action, but that has to be done every day.
The circuit uses a PT8A262 PIR controller (which is for a relay to switch the mains), and would be grateful for some help please.
I traced the circuit as best I could and found it was very like the one in this PDF of the actual controller.

Using page 12 mains supply with relay
Is there a way to fool the chip into believing there is constant movement, or maybe bypass the chip altogether?
If need be I will remove the chip and wire the photocell to the relay driver.
Regards Alan
