I have a PIR controlled light (that controls itself and one slave - it
in turn is also controlled by an external PIR).

It has started exhibiting behaviour where it will trigger as normal.
However once triggered it will then retrigger all by itself every time
the delay expire. Hence the light is in effect kept on until the dusk /
dawn sensor turns it off. You can in fact see it retrigger as every
delay seconds the bulb flashes off very briefly.

Anyone know of a likely cause of this? I have tried masking off areas of
the sensor - but the problem persists.
