Maintained or not?

Doomed · Jan 7, 2015

Tasked with changing all the lights in the communal areas of a block of flats.
At the moment all fittings are thorn 28W 2D with emergency back up that are permanently on.
Client has specified Lumineaux 16W 2 D bulkhead emergency/sensor fittings.
This would mean that the fittings above the fire doors to the stairwell and the stairwell itself would not be a maintained fitting, rather they would be on a movement sensor.
I seem to recall that lights in these locations would have to be maintained, but I'm not back in the office to be able to check for a few days, probably monday.
Useful answers please. Random insults accepted if they are funny.

I've used the Kosnic units. the fittings have the EM module pack you then choose the led lamp pack you want.
The lamp packs will also fit most 2D fittings, so if you want to leave the original bulkheads up just get the EM modules & the lamps.

Is there a building regulation with regards to location of fittings ?

May be wrong, but I thought you had to work to BS 5226-1 ?

My understanding is that non-maintained fittings would be used in a building where the users would be familier with the building. Maintained fittings would be fitted where users are not familier. Such as a block of flats or a cinema.

Fittings should light up fire extinguisers, fire blankets, first aid kits, call points, communual areas - change of direction/level, steps and at the final exit of buildings, both internal and external.

There are bound to be more but have a look at the electricians guide to emergency lighting.

All em lighting comes under BS5266....There is no rule for using maintained lighting in public buildings, But most designers will used maintained because the look better then a load of cheap non maintained bulkheads fittings, screwed to a ceiling next to an expensive fitting.
The use of a maintained fittings, allows all the lighting in a corridor, to look neat and match normal fittings, and to used as such. The result looks better and sensors or normal switching can be used.

This is a nursing home, we ripped all lighting out, and replace with led sensor fitting...every 3rd light fitting is a maintained em light....you must agree it looks neater when all lighting is the same
