Shunt trip for lights in the hood?

[Sierrasparky]

I was wondering:
In a commercial kitchen are the Lights also required to be turned off in the event of the Ansul being set off.

Also I assume that the exaust fan needs to continue but make-up air is turned off.

Every system I've done the lights have to turn off. Different jurisdictions have different requirements. Check with the local fire marshall for all the local requirements because they vary. Most systems I've seen the exaust fan turns on and the makeup air drops out. I remember one area where they wanted both fans off.

I will be willing to bet that no one can find a code requiring the lights to be shut down.

If by "code" you mean a standard such as NFPA 17A or NFPA 96, you're probably right. I'm sure you can find at least one local jurisdiction out of the roughly 3,000 in the U.S. that does require it.

Lights and makeup air off, exhaust on.

I bet tons of jurisdictions ask for it, I bet damn few have it in writing.

They come prewired that way, so it is what it is.

I was called back by the g.c. to wire some hood lights to turn off with the other equipment in order to pass inspection. I don't mind. I got paid for my time. I was always under the impression just the cooking equipment itself was to turn off, as in, anything that might perpetuate the fire. Fire marshal was just looking after the safety of his men and didn't want any lights to present a shock hazard to anyone responding to the fire. Especially if they are damaged in the process.

I've been killing the lights in the fire-suppression systems I've done, except when told it wasn't necessary.

I thought the OP asked if it was required, I must have been mistaken. :grin:
