2 way & intermediate pir is there such a beast

[the pict]

Usual thing, long hotel hall lights left on all day and night so control solution needed, is there products I can swap over from standard 2 way and inter switching, ceiling mounted preferred, I have had a trawl but cant see any at does not require a load of farkling around

Yes timeguards PIR sensors can we wired to achieve this

Up to 5 iirc

 

[westward10]

You mean motion sensors.

 

[the pict]

Yes, lazy habit like say hoover as a generic for a vacuum
but motion sensors

If the hallway lights are going to be off you'll need to make sure every Room to hallway door is covered by sensors and the lights are triggered immediately.

Or maybe a high/low capacity.

I may be wrong, but I thought as a PIR will turn on then turn off again, there is no need to wire it like a conventional 2 way system. Just take a PL to each one and then a feed to the lights. If any activates then the lights come on. When they are all timed out the lights are off. Or am I over simplifying it?

 

[ruston]

No ,but as @snowhead has said the corridor may not be safe plunged into darkness.

You are correct the general switching can be removed but as Snowhead says all means of access would require coverage from the sensors.

the trouble having motions detectors on the ceiling are great.
but however if a long hall you say . I would change the lighting to led
because if the sensors are not set wright and you got a lot of traffic e.g.
customers it will go on and off like a space ship .

@buzzlightyear
My local hospital corridor is like that only it is high/low. Very eye catching.

Yes this is a good alternative. the corridor remains lit all the time at low level then when somebody activates the motion senor the lights go to high level for a timed period.

just about to start one next week,any info on something like surface led fittings ,high/low

 

[the pict]

High /low may well be the answer thanks

 

[the pict]

OK what exactly is high low lighting as a google finds nowt

 

[ruston]

A low level light on permanent ,switched to high level when activated .

Have you got a maker or product info as I get nothing

 

[ruston]

This at a quick look.

The ones I have seen are linear though.
Contact them I am sure they will be able to help you .
What type of lights are fitted?
Edit . And this .

CP electronics make sensors with all these functions that can be programmed by their remote. We use them all the time for warehouse lighting. What's described in the above posts is called step down illuminance.

CPE COMPACT INFRARED PROGRAMMIMG HANDSET - https://www.mylights.co.uk/p/PIRANDPRESENCEDETECT/CP-Electronics-IR-Programming-Handset-For-Presence-Detectors/UHS5

Obviously the light fittings would have to be dimmable to be compatible.

Try searching for "Corridor function". Tridonic are one supplier of these type of ballasts.
