• Air Damper Compatible with Overture™ connected IAQ system BROAN® interlocked make up air dampers provide outside air when required to keep the air-in the home fresher by allowing the range hood to operate at optimum levels Universal design works with any BROAN® range hood to balance indoor air pressure by providing interlocked make up air without requiring a direct wire connection between the range hood and the damper Instead a sensor is attached to the exhaust duct to detect if the range hood is operating Slave dampers (MD6S, MD8S or MD10S) 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 Slave dampers can be "ganged" together to provide a cost effective means to provide for higher volumes of make up air Can be used to meet international residential code (IRC) based requirements for make up air Interlocked make up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well balanced environment Fresh air wall caps are required for use with make up air dampers Normally closed damper Automatically opens when exhaust fans are activated Foam seals minimize air leakage Damper adjustment screw for balancing adjustments Use with fresh air inlet model 610FA for 10 in dampers
