secouru Explanation: Please see glossary for previous entries, in FR > EN I think. 'maintained' means the function is 'maintained' in operation in the event of mains power failure; traditionally, that would have been via a central emergency generator system, but nowadays with low-consumption devices, there is an increasing tendency to make each individual unit self-contained. See also the special term used in emergency / safety lighting, BAES (bloc autonome d'éclairage de sécurité) and other related devices. -------------------------------------------------- Note added at 2 heures (2016-06-05 12:45:16 GMT) -------------------------------------------------- That, Gaël, depends on the excat details of the particular system you are dealing with. You could check the relevant legislation as it applies to the specific equipment you are handling. Self-contained battery-powered units only have a certain life — typically, this might be (say) 3 hrs just to allow evacuation of the building; it is not inconceivable that EVEN as self-contained units, they might be connected to a 'maintained' supply so that in the case of an emergency, they are kept functioning indefinitely, as long as the maintained supply doesn't also fail! Of course, whether or not they still switch on in the event of mains failure may be affected by the presence of the 'maintained' supply; however, modern devices are often dirven in a more 'intelligent' way, so the presence of the 'maintained' supply wouldn't necessarily prevent them from coming on if the 'normal' mains supply failed (only they would stay on longer!) So I'm afraid it all really depends on EXACTLY what your context is; it is POSSIBLE that your 'maintained / non-maintained' simply refers to whether or not the lumnaire does include this fail-over mechanism... Although Florence's idea of the actual illumination of the sign being 'maintained' is appealing, this simply isn't the normal terminology we would use to describe that in EN, where the term 'maintained supplies' etc. is usually used in a very specific context. Feel free to send me your entire document privately if you would like me to comment further... -------------------------------------------------- Note added at 2 heures (2016-06-05 12:46:43 GMT) -------------------------------------------------- If your source text is of questionable, non-native EN, then it is possible they simply mean 'maintenance-free' — but then that is a whole different ball game! -------------------------------------------------- Note added at 6 heures (2016-06-05 16:59:01 GMT) -------------------------------------------------- It's impossible to tell from just this small amount of context what exact sense they mean it in; do you have any other information that might indicate if these devices even have a mains supply going to them at all? If not, then it is a little difficult to see what kind of meaning 'maintained' could have here; the idea of 'stays alight even if the mains fails' WOULD make sense (given the difference in the function of the 2 units), except for the fact, as you say, that these units appear to be self-contained with their own batteries anyway. If you really have no further clues at all from the rest of your document, you may be well advised to seek clarification from your customer. -------------------------------------------------- Note added at 9 heures (2016-06-05 19:45:47 GMT) -------------------------------------------------- Aha, Asker, I think I may have fathomed it! If you look at your 2 lighting units, the first one consumes only 4 W but has 800 mAh NiCads; the second one consumes 6 W, BUT only has 600 mAh NiCads (and at a lower voltage); it says it will last for 3 hrs in the event of a power cut; now MAYBE here we have a definition of what 'maintained' vs. 'non-maintained' means here — keeping the light source going for 3 hrs isn't long enough to meet the 'official' standard for what is 'maintained'; whereas the lower consumption unit with the larger-capacity batteries will perhaps keep going longer — long enough to meet the 'official' 'maintained' standard, for example. That is a plausible enough scenario... it would just help to have other corroborating context and/or sight of the relevant standard. -------------------------------------------------- Note added at 9 heures (2016-06-05 19:49:46 GMT) -------------------------------------------------- Here is an interesting page, which describes what sounds like similar luminaires; they too have batteries, but seem to be able to be used in this 'maintained' / 'non-maintained' fashion — the wiring diagram clearly shows the 'maintained' version being connected up to a second power source. I don't think this still give us a definitive answer — but at least it is tending to confirm what i've been describing. http://www.eclat.co.za/Cee_Guida.htm -------------------------------------------------- Note added at 9 heures (2016-06-05 19:52:52 GMT) -------------------------------------------------- There is also something sightly odd about their figures — the 6 W spots @ 3.6 V would draw 1.67 A, meaning that on a 600 mAh battery they would last at best 20 mins, certainly a long way from 3 h! Unless, of course, the unit takes more than one of these batteries, which seems the most likely explanation! -------------------------------------------------- Note added at 9 heures (2016-06-05 19:55:26 GMT) -------------------------------------------------- OK, NOW we have a PROPER explanation, and I'm sorry to say Florence was right and I was wrong: this IS all about being lit or not all the time! Many apologies to Florence for having doubted your word, which i read rather too hastily, I fear! http://www.luxintelligent.com/technical-support/faq/posts/20... |
