The Designer Series

The Designer Series Fire Suppression Range Hood System was introduced as a higher quality alternative to existing 300A retro-fit "kits".  These systems were normally installed into a standard residential range hood to provide a basic level of protection for a light-duty cooking application.  However, retro-fitting is never ideal because of the variables involved; installation quality, conspicuous design, and non-commercial technology could all effect the performance of the system.  The Designer Series is engineered for similar applications but incorporates true commercial-grade technology into a fully integrated, pre-engineered ONE PRODUCT system. 

Fulfill a two product spec with a single product submittal that offers lower installed cost, lower materials cost and a significantly finer finished aesthetic.  That's The Designer Series.

The D1000 

The D1000 fulfills all of the theory and intent behind a type 1 commercial hood with fire suppression (NFPA 96, 17A & UL/ETL 300) in a system designed for use over a residential grade appliance.  Products in this category are listed to UL/ETL 300A.  The term residential grade fire suppression is a bit of a misnomer - these types of systems are intended to be used within a commercial space, when a residential-grade appliance is used in a “not for profit” cooking application.

Our D1000 is the industry’s first fully integrated, pre-engineered system.  The suppressant canister is located within the hood and ships from the factory pre-charged.  There is no interaction with the fire suppression system at installation other that removing the safety pin and lock-out key - because of this it is often installed by a mechanical equipment contractor.

The D1000 also includes an environmental monitoring system, designed to interact with the cooking environment and minimize the likelihood of a fire event.  This is a two stage temperature monitoring system.  At a mid temperature set point, the system will automatically engage the fan on high in an effort to dissipate heat from the area.  At a high temperature set point, the system will preemptively disconnect the cooking element to the appliance PRIOR TO suppression system release.  If these two stages of “pre-suppression” do not stem the tide of a growing fire event, the fusible links will melt, causing the system to actuate mechanically - consistent with other commercial fire suppression systems.

The Denlar D1000 is designed to fulfill all of the theory and intent behind an otherwise required commercial hood system while also incorporating industry leading environmental monitoring technology.  The D1000 will not only automatically suppress a cooking fire event - it will work to minimize overall fire risk in the space.  Engineers, designers, facilities managers and code officials should be confident in recommending and approving The D1000 in all applications where a residential-grade appliance is used in a “not for profit” capacity within a commercial space. 

 The D1000 carries the following certifications & listings:

300 vs 300A - The testing standards used in evaluating and listing a 300A system are exactly the same as those used for the 300 commercial system, only a residential-grade appliance is substituted as the heat source.  Bear in mind, a residential-grade appliance produces significantly lower BTU output when compared to a similarly sized commercial-grade unit.  Both UL & ETL list products to the 300A standard.

ICC/ES LC #1031 - The D1000 is the only 300A system recognized for use by the ICC.  Listing Criteria #1031 officially defines the system as “a Type 2 hood with Type 1 capabilities designed to protect a residential-grade appliance used in a commercial space”.

ICC/ES PMG #1122 - The D1000 carries a listing provided by The ICC’s Evaluation Services division.  This listing officially recognizes the system for use within The I-Codes and specifically states that the installation will comply with the 2009 and 2012 IMC, UMC and IFC.  The D1000 is the only product of its kind with this certification. 

NFPA101 - In a 2012 amendment to the NFPA Life Safety Code, the National Fire Protection Association created a standard for the operation and application of a 300A system.  The Denlar D1000 was the basis of design behind this new requirement.  The language used specifically refers to residential health care facilities, but where NFPA101 is often used as an alternative means of protection, applications of the D1000 span far beyond this limited scope.
