2 x 2-way lighting

[HandyMandy]

Hi

New member here looking for some help with 2-way lighting in a townhouse - i.e. entrance lobby, living acc on 1st floor and bedrooms on 2nd floor.

Client wants 2 way switching for entrance lobby and 1st floor landing light. Thats fine. He also wants 2way switching for 1st floor and 2nd floor landing. Snag. How do I get the 1st floor landing light to be controlled by 2 separate 2 way switch circuits??

Have tried to draw it out but can't make sense of it.

Any offers (other than having 2 lights on the 1st floor landing on separate control circuits - the client does not want that).

Many thanks

Landing lights all on the same circuit with intermediate switching?

Trev

Thanks for the quick reply.

Have suggested that - it seemed the easist way but the clinet does not want the lights to be on/off. He wants to have 2 separate "circuits" i.e. lobby/1st and 1st/2nd.

Coming to the conclusion this will not be possible but there are loads of town houses around so what do they do?

Basic intermediate switching. How is it wired at the min, 3 plate?

 

[trev]

The town houses (stupidest designation for a building ever imho) use one circuit and intermediates mate.

I might be being thick here but I don't quite understand what he wants. How many points does he want to switch from ?

 

[trev]

I'm guessing but think he wants hall and first floor on/off and first and second floor on/off.

Oh now I'm understanding trev. I'm with you one circuit with intermediate switching seems the way forwardforward

Could put each light on it's own PIR, wouldn't give the client exactly what they want but it would be a pretty cool solution.

Thanks guys!!

In a past life I worked in a Major Corporate and thought that awkward clients were unique to that environment.

Oh how very wrong I have been!!!

I will go for Intermediate switching or suggest that the lobby stands alone (given that the 1st floor landing light is att he top of the stairs anyway).

Thanks again.

PIRs for the hallway..................

Nah.

Cool though!

Isn't the problem the required system?

It's a bit silly to have the fist and second landing lights come on every time the entrance lobby light is switched on.

Surely that's not what the customer wants though?

By having 2 x light fittings on that landing? or go the whole way and use grid switches and having 2 way control on each landing for each light. Now that would be fun!

It would take a bit of working out to make sure it works, however what about the following using a couple of 250V diodes?



You could use a Grid switch on the 1st floor landing with 2 two way switches in, either one operating the 1st floor light via a Diode....but these would be better replaced by a relay to ensure that only one light turns the light on at a time or it simply swaps over to the other source..

Only if you don't mind the 1st floor light running on half wave rectified DC, so it's going to a bit dim. And you'll need diodes rated at well above 250V to cope with the peak voltage. But yes, you could do it with a couple of relays.

Handy, you can get Diodes that will pass the full ac voltage, just can't recall what they call them off the top of my head, however the best way to do it would be with relays..actually if you pick the right relay then one would do it...

Ground floor light - 2 way G-1
First floor light - 2 way and int G-1-2
Second floor light - 2 way 1-2
