help on wiring emergency switch lighting

[andy999]

Thanks Dave, I'm just going to sit back and mull it over.

Just to complicate things , we've started using meg test modules , you run all your em switch wires back to mains and through a contractor or contractors pending on amount of circuits
And the test module controls the contractor N/C
Placing all the emergency lights into test mode with the press of one button
You can set it on 3 min 30 min 3hour and it resets itself after activated time
No need for key switches everywhere
I really like the system

Not quite got to this stage in the project yet but trying to think forward on what needs to be done, I haven't had much experience with wiring emergency switch lighting, Live and Switch Lives. Can someone tell me if the wiring is wrong in this wiring sketch and how to rectify.
I've deliberately left out Earthing.

Like your little sketch , what app / software do you use

if you're going to the trouble of installing that type of thing then why not just fit self test fittings or an intelligent system which actually records the test results for you.

I can see a problem with that timer system where it could reset itself before you've walked round to all of the fittings at the end of the test to check that they are still illuminated.

Yeh I agree with the resetting itself before walk round finished , you don't have to use the timer , something we have been specified to install , the designer obviously thought fit for purpose on particular installation

out of interest how much would your suggested ideas cost , could be something I could put to our designers if cost effective

I haven't a clue, all I know about your installation is that you have fitted a fancy timer relay to do the testing!

I can only install what has been specified by our designers , but thanks for reply

meant to like not dislike
Yeh wasn't too convinced myself , but seems like a good method , saving on key switches everywhere , suppose more things to fail though in the installation
It will soon become outdated the rate things are changing , if it's a step in the right direction who knows
