    Good Afternoon, 


    There is a school cooperation that has six of the Greenheck versions in their Home Economics room.

    They were installed in 2021 and approved by IDHS plan review for such use. 

    They have electric shutdown via the built in Shunt trip, fire alarm contactors, and a manual release. All have liquid tight welded duct work with rooftop exhaust fans.

    A contractor from Louisville have been servicing them on a semi annual basis when they conduct the main kitchen inspections. So the service schedule is being treated the same as a UL300 unit. 

    I'm not supporting theses one way or another, However, I think they may be better than nothing.

    Just letting folks know they are out the and have been approved for use in an E occupancy.

    I'll agree with the rest. I saw the unit in person once; It's liquid based and has some electronics involved, and I was intrigued, but definitely not for anywhere a Type I hood would be required. But when residential/low volume cooking appliances are acceptable, it could be good if the UL listing matches the use. 

    The liquid agent would be a lot less messy than the Stovetop Firestops, but if I recall correctly the price started upward of $300.00 per unit. It would be nice to see them in apartments, but we already can't get them to spend $50.00 for the SFs.

    Hello,  I would have to agree with Darrell.  Cross refferencing with a competitor Greenheck,  https://www.greenheck.com/en/products/kitchen-ventilation-systems/kitchen-ventilation-products/kitchen-exhaust-hoods/fire-ready-range-hoods ,   This is build to UL 300A standards not UL 300 (Type I) and is only designed for residential.

    I'd be cautious proceeding with these without a lot more information.  In a quick look at the certification page on their website, the ICC certification link goes to a "page not found", and the UL certification is for  "Residential Rangetop Extinguisher Units", which are not equivalent to a Type 1 hood.  As a reminder, NFPA 96 has not been adopted in Indiana, and 2014 IMC 507.2.3 requires Type 1 hoods over domestic appliances that can produce grease or smoke.   I can't think of an application for these units in Indiana that would meet the prescriptive code requirements.

    Has anyone heard of, looked at, or know anything about the Guardian Hood Suppression Systems for domestic hoods? I heard about them yesterday at a conference. The website says they are UL-listed and NFPA-compliant. From what I'm understanding they are a cheaper alternative to a Class 1 hood for places like daycares that are in a residential setting. Any guidance on this would be greatly appreciated.
