overide switch

[D Skelton]

Not as expensive as a proprietry lighting control system (and from what the OP is wanting to install, a crap one at that). A PLC would be cheaper still but useless if the OP has never used one before.

I agree however, 2 way is by far the simplest and cheapest option but then again, I'd present the cost difference to the customer and install whatever they wanted. If they wanted to splash out a few hundred quid to get rid of what they think would be a 'busy' switch by the bed it's their choice, who cares.

Well exactly....so thats put to bed then....lol

 

[Engineer54]

The only way this would be possible using hard wiring, is by means of impulse relays!! The French use them extensively on lighting circuits. The system can be installed to exactly comply with the OP's clients requirements, as the switches are basically push buttons or momentary action switches (bell switch)!!

A hell of a lot of trouble and cost for next to no benefit, ...a case of more money than sense!! lol!!

I'm guessing you hadn't read through the whole post before replying there Eng?

You'd be right too!! lol!!

Just seen your drawing, same can be done with just 5 impulse relays, but still a completely daft idea!! lol!!

 

[D Skelton]

Thought latching relays and impulse relays were the same thing?

How would you do it with only five?

Exactly

A PLC would be cheaper still but useless if the OP has never used one before.

Yet the Loxone Miniserver the OP wants to use IS a PLC so would need programming, a cheaper option here with free software and tutorials.

 

[D Skelton]

In a way you're right, except it is set up purely for home control and has its own OS and proprietary means of programming which is not RLL. The OP will most likely have been on one of Loxone's courses which is why he mentions them so although he might be able to program a mini server, I doubt he'd be able to program a PLC.

Rako wire less switch with control packs

Would take a few hours to get that running on that

 

[Robert Turnbull]

You need a pack for every switched circuit
They are about the size of a low voltage transformer (downlights)

Then how ever many switches you require.

Doesn't take long to set up.

Good stuff

Just had another think about the use of inpulse relays, you can do the job with just four of them, using the master switch to send a pulse to all four relays... It'll also turn all the lights ''On' as well as ''Off'' too!! lol!!

 

[eddielarge]

Love all the input. As was stated 2 way is cheapest and simplistic. But all the other ideas are great too as its a problem solving question. And you are right Ioxone is the system I can programme that's why I mentioned it. But always like to explore other avenues. I suggested loxone because once fitted the possibilities of controlling fan times and expanding to over rooms are endless. But ty u for all input guys.

But then you'd have the problem of if two lights were on and two were off for example, the pulse would switch the lights that are on, off... And the lights that are off, on. Also, you need four seperate VF contacts to prevent one pulse from one switch turning all lights on and vice versa.

I personally can't see how it can be done with less than 12 relays?

 

[Des 56]

Treat the situation as you would as if it was a motor runing a machine

All lights on same mcb
Fit a latching contactor and a timer at the consumer unit
At the bedside, fit 2 bog standard retractable plate switches,one for energising the contactor and one to be used as an emergency to de energise the contactor if needed before morning/a stop button in effect
The contactor to have normally closed poles

Use simple timer to duplicate the opening function of the emergency switch
All lights can then be de energised at the bedside,they can be re energised if needed,or will revert to normal operating in the morning timed period

I'm complying with how the lazy cow wanted the system to work. ...eg, she switches them all on as she goes from room to room and switches them all off at side of the bed!! 4 impulse relays and 5 switches will do that, it will also switch them all on again in the morning!! lol!! As has already been said, it's a totally daft idea, this client just has to be a Blondie!! lol!!

 

[D Skelton]

Lol, but what if she forgets to switch one on before she goes to bed? Then when she goes to bed she will switch three off and one on?

You're just making a very daft idea even dafter! Haha

You're right, either blonde or has more money than sense lol.

 

[telectrix]

why not fit a PIR to each light. then a switch at the bed to break the feed to the PIRs.

Yep that'll work too, ...well until the PIR's start playing up anyway!!
