I have 2 external PIRs operating 2 floodlights all in different
locations but connected so that 1 PIR will turn both lights on.
I need to adjust the timings lux/sensitivity.
Before I climb a ladder can someone advise what the priority is for the
LEDs, eg if say the 2 LEDs are set for timing at say 15 seconds and the
other at 3 minutes, if the 15 second LED triggers the lights does it go
off after 15 seconds or 3 minutes.
Does the one that triggers it set the timings or can that be overruled
by the other?
Hope this makes sense but the less time up a ladder making adjustments
the better as I hate heights.
Yup I see your point in that there is no capability for the second PIR
to force the lamp off... so not true two way switching - although for
many it kind of fits since it allows for two separate switches to turn
the same lamp on.
ok I renamed the section:
I have it sorted now but to clarify its like an alley at the side of the
house the PIRs are either both activated or just one depending on
circumstances, it is wired so that both lights come on regardless of one
or both PIRs being activated.
It was set up a few years back but for some reason the settings unsetted
themselves when they came on they would stay on for say 2 minutes turn
off then straight back on again, the problem was in the PIR settings not
the LED lamps. (and I lost the instructions), maybe due to the hot
weather or some other reason so I had to bring them back to a useable
PIRs often have dusk/dawn sensing as well. So they won't trigger the
lamps in daylight (there is usually a control to adjust the
sensitivity). That does mean you need to be careful with placement of
the lamps wrt to the PIR though - you can get a situation where
triggering the lamp can then trip the ambient light sensor which then
turns the lamp off again even if the PIR is still being triggered.
