Emergency Lights 30 cm away?

[Harrypops]

Does Emergency Lights have to be 30cm away from the light, like heat alarms. These are non maintained self testing illuminators.I got to fix them tomorrow

You already have a thread running on this topic. If you are installing emergency lighting you should know this. Why is an automatic detector affected by adjacent obstacles and does this apply to emergency lighting.

Thanks again Westward. It seems that the emergency light does not have to be 30 cm away from the light, right?

Are you designing this or doing it to spec. These are safety systems and should be installed to BS5266:1.

Westward I have bought the lights that are to BS5266 standard, I am just wiring them to the light rose

The lights are not made to BS5266 but the installation is designed to it. So you have designed the system and will commission it as per this Standard?

I'm assuming this is a commercial job if multiple units are being mentioned.
There's quite a lot more to the location of emergency lighting than how far it should be away from other things.
Off the top of my head things like
-what does the fire risk assessment say
-where do escape routes change direction and level
-how wide are corridors
-which stairwells are escape routes
-even how big are the toilets!

...all play a part in dictating where you need them, how many you need and how bright they need to be.
If people 'fail to escape' you can be held liable as the designer. If you can't prove competence or experience with BS 5266 then in the nicest way possible you might want to protect yourself and reconsider this job, or at a minimum tell the customer that you want to see the FRA and you'll need to consult whoever did it to approve your plans to ensure they (the customer) cannot be held liable for any errors of judgement.

Oh ok. I've just had a quick look on the internet but don't understand it. Will look at properly another time. Thanks

Westward I have read more. It seems that I can just connect the live and neautral to the light circuit. By design I suppose you mean where to place them. it's a terraced 3 level house. I can place them near the light on the 3 levels and the extension so that they light up all the passages and reflects the light 20 metres away.
