Prior to this product hvac were run through a drop soffet around the perimeter of the room with sidewall registers. Not typically what the architect wanted, but, since no systems were listed with a penetrations they had no choice. The CFD-521 solved the problem – provides architectural freedom and reduced cost. As a result the CFD-521 is now the basis of design in most low/mid-rise condominium/apartments.Factory Mounted Duct Smoke DetectorAfter a series of jobs where the interface wiring between the FSD motor and the duct-smoke detector was mistakenly forgotten a group of design engineers requested that we develop the capability to factory mount and interface wire a duct smoke detector onto our FSD. Sounded simple enough, so we engineered a compact solution complete with single point interface wiring and received approval from UL within a matter of weeks.Fire-Rated Bath Fan AssembliesPioneered testing at UL. Often times these fan assemblies contain significant plastic components (motormounts, fan wheels, etc.) which melt during a fire. Which, in and of itself is not necessarily a problem. However, the problem arises when, say the motor mounts fail and the motor falls through the protective thermal blanket of the ceiling radiation damper leaving the penetration unprotected. Specifying a UL Fire-Rated bath fan assembly ensures that the entire product will perform in a fire.Out-of-Partition DesignsMotor mounted in the airstream (our OP model) or in a side-panel compartment (our SP model). No other manufacture offers both solutions.Only manufacturer with wood stud installation approval.Designed for grille terminations (corridor walls, shafts penetrations, etc.).ProsEliminates the need for fire-rated door to access motor through direct access to the motor by removing the grille.No space required behind the wall for the motor.OPGrille size = duct size.Narrower widthsConsLonger sleeve lengths on shorter height units. Shallow cavity (or chase) depths can be a problem.SPShortest sleeve depth Ideal for shallow cavity depths.Grille width = 8” + Duct width.4-Way InstallationA standard feature on all of our FSD and SD products, 4-way installations virtually eliminates site-condition coordination by allowing the contractor to install the product right-side-up or up-side-down in vertical wall or in horizontal floors. Gone are the days of detailing right-hand left-hand mounts. Now, if a beam or a wall is in the way of the motor, you simply flip the damper over and finished the installation.
