Emergency key switch wiring

[dave19]

Hi Guys,

Can you help ? I just wanted to know how you wire a key switch and normal switch together. Is this how it should be :-

Feed from board to common on key switch
power to emergency lights comes off the load side of key switch
loop feed comes off the common side of key switch to common side of normal switch then
power to normal lights comes off load side to normal switch.


Is this it and if not is there a different way of doing it. Please explain in as simple terms as you can. Diagrams would also help ? Thanks guys.

Dave.

Are you trying to tell me BS5266 makes no reference to lux levels?

no , i'm saying it doesnt request lux tests to be carried out during annual testing once the system is in service - read my statement that you just quoted again.
it also recommends standard lighting remain functional during testing as was pointed out many many posts ago by another poster.

depends on how the circuit is set up
emergency lights seperate circuit/switch wire
or all together - loop from key to l/sw so the key is master and the l/sw operates as normal until key put into power cut mode

 

[glasgospark]

basically pass the feed through the key before going to l/sw

It says the lights have to be bright enough.
You can prove they're bright enough with a tester which tests how bright they are.

though bs5266 doesnt even ask you to carry out such a measurement during in-service testing ??

Maybe not but it says the lights have to be bright enough.

Well apparently it's not obvious enough, hence why I've had to say the same thing several times.

and each time i've pointed out that youre not required by offical guidance to do the measurement you say needs to be carried out but you just wont listen.
