EM Lighting

[pennychew]

Something i know little about, i know i can find loads out by googling and searching on here but i'll probably just put it off then whereas if people post info up i'll read it and ask questions that way!

Some of the places i work there are PSU's mounted up by the panels and in others there isn't. I know you have maintained and non maintained but not sure on the differences.

Not looking to design or install any of this, info is just for learning about it

Cheers

Maintained fittings- lamp on constantly weather in mains fail mode or charging

Non-maintained fittings- lamp only illuminated in mains fail mode

Sustained fittings- These switch on and off with a switch, but also require a permanent feed to charge the batteries

There are also some installs where you will get a remote battery pack and this will feed several em lights across a site.

basically maintained is on all the time, non-maintained only illuminate on loss of supply.

The remote battery pack is what i have seen on a couple of sites, if this battery pack is present would the em lights still have a battery inside?

No, ad the remote batteries will operate the lamp in the event of mains failure.

So if you had a room with 6 battens and you wanted two as EM you would use all standard battens but just wire two up to the remote batteries?

I am not too sure if you can just put a fluorecent fitting onto a remote battery pack. As you need to provide a seperate ballast to drive the EM side of the fitting.

It shows how you would convert a standard fitting to an EM one within that .pdf.

I've just been in the shower and I was thinking about that!

I'm only up to page 8 at the mo, I'll go through it properly when I get back in tonight

Is it possible though with a remote battery pack?

 

[pennychew]

Ill take a pic of some fittings today and see how they've done it

I can't see why not, you would still need an EM ballast withing the fitting though.
