Maintained emergency lighting question

[Micky d]

Hi, I have been asked to fit two maintained emergency lights in a loft conversion (customer had them given new) I have never wired these before. There is twin and earth from the ceiling with permanent live and also a switch wire from the light switch. There are 5 terminals fuse/perm live/sw/e and n. I either get the lights permanently on or running off the battery. any suggestions!

if they are running off the battery, then that suggests that the perm live has been interuppted. if the lights are permanantly on, then youhave crossed your perm and switch live. I wire emergency lights so that your perm live goes through a key switch, then into the common on your normal switch. From there, one goes straight to the light, and the switched live is taken from the other side of the switch. Be sure to mark the switch live. Thie abopve arrangement m,eans that when the key switch is operated, you lose all lights fed from that switch, apart fro the emergencies. I prefer this, as it allows an accurate assesment of the lux levels. Some argue that they want only the emergencys to be switched. To wire it that way, you feed the normeal swtch from thwe live side of the key switch, and take the other side of the key switch to the light.

Some fittings have a little jumper so you can set to maintained and non maintained. If you want them so they are switchable then you will need a three core providing s/w live, live and N to the fitting and running the perm live through a key-switch for testing of the luminaire.

Umm just to state the bleedin obvious, you need to connect the spade terminals in battery pack, no offence intended.

Maintained are usable as normal lights with emergency backup.
