corridor lighting from scratch

[bernard41]

If you were starting from scratch with corridor 24hr lighting in an apartment block

what i best, 2d lamps,led lamps, pir switching, individual battery packs in lights, or a cental battery back up, could be a job for the best soluion

You said 24 hour so not PIR switched, so energy saving lamps , take your pick. Light levels could be reduced during the night , give that some thought .

if its a biggish job get a ligting rep involved and take his advice .

Emergency fitts with own batts .

the reason i posted this is because i have a totally unreliable system with 2d bulbs with the emergency and non emergency keep going,I am told pir is not suitable and i thought the lads who work on the ground might have more practical advice that a sales rep. I am looking to start from scratch

 

[Evans Electric]

Not sales rep....technical rep . If they are stopping on you don't want a PIR . Why are you having probs with the 2D s are you buying cheapo ones ?

Frequent PIR switching of 2D lamps shortens lamp life. It is recommended mimimum 15 Min duration.

Difficult to provide definitive advice without the input from the RA; FRA, etc. - there may be specific requirements for certain areas of your building; above & beyond the normative measures to comply with the regulations.

Be aware that CBS for em. lights are required to be high integrity wiring throughout; including final connections to fittings, and fittings themselves. Generally self contained is the better option.

I would use push switches with 10 min delay on a 2 way/intermediate set up and 2D fittings and 2D batt back up ones. simple and cheap and if you set them for 15 mins then thats good for the tubes too....

 

[Evans Electric]

What did you mean by the phrase "24 hour" Bernardo, ? I took that to mean lights are on permamently.

If you're switching them I'd go with the Rev's suggestion , and 2D fittings.

If you go with the electronic delay switches (ELKAY) etc. Ensure they don't react with any electronic ballasts in your fittings, best stick with the Columbus type.
