French term

détection multi ponctuelle

French to English Tech/Engineering Engineering (general) Fire detection equipment/Fire security
Term appears in the second paragraph below.

Contrôles et essais fonctionnels des équipements de détection (SDI):
-Essai fonctionnel de chaque détecteur incendie et de chaque déclencheur manuel.
-Contrôle du bon fonctionnement des indicateurs d’action.

Cet essai a pour but de vérifier la réponse de chaque détecteur au phénomène physique qu’il est chargé de détecter. Ce test est réalisé par sollicitation de chaque détecteur à l’aide d’un générateur approprié. Une des boucles ou zones au moins sera testée avec l’alimentation principale coupée.

Pour la ***détection multi ponctuelle*** :
- contrôle et dépoussiérage du réseau de prélèvement,
test de l’alarme d’obturation du réseau,
essai de détection par émission de fumée en extrémité de réseau (hors présence secteur pour les systèmes secourus).



So far, I have been unable to find an English translation of 'multi-ponctuel' - as specifically applied to fire detection equipment. I have found lots of references in French, however. I know that 'ponctuel' often means 'one-off' - so, by extension could mean 'in isolation' and I am wondering if this is the intended meaning here - that there are lots of these fire detectors, all working indpendently of each other, perhaps? Any help would be more than welcome, as I drew a complete blank on this one yesterday and am still none the wiser!

CMJ/Tony... ...yes, it appears I was looking too far into it... although now you both mention it, I had briefly thought of 'point' - but then gone off at a tangent because I found references to the term 'fire point' which can mean something quite different. This is irrelevant here - but may explain why I moved away from the whole idea of 'point' and forgot about it. But yes, of course, you are both right... and it is very likely to mean, simply, multi-point. Thank you.
CMJ_Trans (X) Oct 13, 2007:
surely it just means "multi-point" i.e. detection at a lot of separate individual points. Don't be confused by the word "ponctuel" which is in fact extremely logical in that it means "at a particular point" and thus by extension "occasional" or "one-off"

multi-point detection

Don't forget that 'ponctuel' is also the adjective that goes with 'point'

Here's one of a surprisingly small handful of Googles that refer to it in this or similar contexts:

Surveillance control apparatus for security system - Patent Review ...

3, Multi-point detection systems. Inventor: MADDOCK PETER RODNEY ... If a fire alarm system is being installed in a construction site of a building or the ...

www.wikipatents.com/gb/2149547.html

I'm actually surprised there are so few, but then again, since most fire-alarm systems are by nature multi-point, I suppose it isn't a feature that needs mentioning very often.

background

From my notes:
Détecteur d'incendie ponctuel – spot type fire dectector
à aspiration multipoint – air-sampling fire detector, aspirating fire detector
linéaire – beam detector, projected/linear beam type detector
BUT there are also linear wire detectors

Your context suggests that these are air-sampling detectors, but I suppose you need to specify "multipoint" because otherwise there might be just one. Unless of course it is by sucking in air from a larger area that a single unit is deemed to cover multiple points ...

Something for you to chase up ...

I simply had to satisfy my curiosity! It would appear my hypothesis above is correct. Read the "définition" at

http://www.chubbsecurite.com/utcfs/ws-487/Assets/Vesda Laser...

A single unit, by sucking in air, covers multiple points. That doesn't stop Chubb calling it a "multipoint detector" though.
