I wonder if someone could kindly direct to the earlier thread on this?

Following a supply outage I have had two PIR controlled floodlights fail
permanently on. The initial failure tripped our domestic RCD (which is
unusual) and took out one lamp. Supply switching the following night
took out the second! GRR..

150 Watt floods are not hugely expensive but access can be a pain.

Are you sure that they have failed? Many of these lights have a
permanently on mode of operation.

The permanently on mode is usually selected by turning the power from
off to on - then on to off - then off to on within 30 seconds.

To revert to PIR mode turn power off for 60/120 seconds before turning
them back on. What may fool you is the light will immediately come on
for the time-out period before going off and being controlled by the
PIR.

The supply outage may not have been clean and may have resulted in an
off-on-off-on power cycle to the lights.

Above is true.
If not "Screwfix" has standalone PIRs.

I think earlier PIR's worked this way but some newer ones need to cycle
through "on - off - on - off - on" which makes them a bit more tolerant of
brief outages compared to the earlier "on - off - on" ones.

OK. About the same price as the complete light fitting and the same
range claimed.

Ta.

Umm..

I did try leaving them off for a few minutes and then back on. I may not
have waited for the full normal *on* time and will recheck.

One of these units is in a poor location as the gas boiler flue is
within extreme range. It seems able to ignore the boiler but triggers
when a frond of bamboo (planted to the side) moves across the sensing
field in strong winds. I already know how to cure the bamboo problem:-)

OK. chaps Panic over! They do go off after the usual *on* time.

Thanks.

Now if only I could get them to stay on by judicious flipping of
switches:-)

They should do, but I can't either.
Mine reckons to switch off then on within a few secs, but it just times off.

Just put a switch across the two live terminals on the PIR relay.

Now that they are working and 'on' try a a single off then on cycle
which is to be completed within a few seconds.

On my lights the PIR can be overridden and switched permanently on
during daylight. On other models the dusk to dawn override may also kick
in.

Depending on the model you might need to do that twice in quick succession.

This is the way all the PIRs that I have bought are supposed to work.
Howvwer in my experience they NEVER work that way.
When I want them to stay on, they won't, and when I don't want them to
stay on, they do.
I would like to buy a PIR without this "feature" but I can't find any.
I also DON'T want them to turn the light on when the switch is first
turned on. They are security lights. The reason should be obvious but
I suppose I'll have to explain it.

It looks very complicated. Complication makes things unreliable and
expensive. I just want a light to turn on at night when there is
movement. Absolutely nothing more. I wish to turn off that faclity and
on again without the light going on.

What makes you say that ? Would you call your computer, telephone, TV,
unreliable? They are all significantly more complex than, what iif you
look at it is in effect a couple of chips, a couple of transistors and a
couple of relays

a fairly standard circuit as can be found in most PIR detectors except
that it has two relay o/ps rather than one

It's all proven, reliable technology, and given the environment in which
it's meant to work extremely reliable

You need a switch between the PIR output and the light and then leave the
PIR powered up all the time.

Well since you mention it, yes my computers and telephones are
unreliable. I had a graveyard of them but gave them away for recycling
or for stage sets (the phones). My Sky box and its remote are very
unreliable and I'm thinking of chucking Sky. Obviously I have done all
the things that are recommended.

I've had expensive PIs that have all failed. Some cheap PIRs are still
working, so I keep buying that brand. They cost about GPB 3 so that's
not a problem. Did I say that the cheap ones usually work for years?

The obvious is usually difficult to spot:-) Thats why we make things
foolproof.
