Interlocked make-up air dampers provide make-up air when called for to keep the home comfortable by allowing the range hood to operate at optimum levels
LinkLogic® design works with SmartSense® ventilation fans and select Broan®® range hoods to balance indoor air pressure by providing interlocked make-up air. SMD8 uses existing AC wiring to communicate between the damper control and ventilation devices with no added wiring
Slave dampers (MD6S or MD8S) are interlocked to the main automatic or universal make-up air damper and open in unison for synchronized operation. They close, along with the main damper, as soon as the range hood is powered off.
Can be used to meet International Residential Code (IRC)-based requirements for make-up air
