Specification Sheet

®
LinkLogic
®
digital control module
• Installs in any electrical box and communicates over existing
power lines in the home
• Controls 120VAC to the 24VAC transformer, causing the damper
to open or close as needed when ventilation devices are turned
on or off
MD6T/8T/10T
Universal design works with any BEST
®
or Broan
®
range hood over 300 CFM to balance indoor air pressure by
providing interlocked make-up air without requiring a direct wire connection between the range hood and the damper.
Forms a complete balanced ventilation system by linking SmartSense
®
ventilation fans and/or select BEST range hoods
using the LinkLogic
®
system.
Features
• Heavy duty galvanized steel
construction
• Includes air flow sensor assembly,
low voltage switch and 24VAC
transformer
• Sensor installs directly to exhaust
duct from range hood
• Available sizes: 6-inch round
(MD6TU), 8-inch round (MD8TU)
and 10-inch round (MD10TU)
normally closed
Installation (see adjacent)
• Use fresh air inlet, Models 641FA
(6"), 643FA (8") or 610FA (10"),
to bring outdoor air in from exterior
• Insert within a 6-inch, 8-inch
or 10-inch duct running from an
exterior wall to the cold air return
of a forced-air system
• If there is no forced air return, the
make-up air duct can be run to a
wall or ceiling register in a location
that minimizes concerns about drafts
and maintains a 5-foot separation
from the cooking appliance or hood
• Damper assemblies can be “ganged”
for high volume applications
• Ganged dampers open and close
simultaneously
• Low-voltage sensor can be installed
onto any exposed section of the
exhaust duct while taking care not
to interfere with backdraft damper
• Controls 24VAC transformer
causing the damper to open or close
as needed when air flows as a result
of turning the range hood on or off
Features
• Heavy duty galvanized steel
construction
• Includes 24VAC transformer and
LinkLogic
®
enabled make-up air
damper control module
• Available sizes: 6-inch round
(SMD6) and 8-inch round (SMD8)
normally closed
• LinkLogic
®
system uses existing
AC wiring to communicate
between damper control and
ventilation devices and requires
no added wiring
Installation (see adjacent)
• Use fresh air inlet, Models 641FA
(6"), 643FA (8") or 610FA (10"),
to bring outdoor air in from exterior
• Insert within a 6-inch, 8-inch or
10-inch duct running from an

and maintains a 5-foot separation
from the cooking appliance or hood
• Damper assemblies can be “ganged”
for high volume applications
• Ganged dampers open and close
simultaneously
• Transformer and make-up air
control are easily installed adjacent
to the make-up air damper
Balances indoor air pressure by providing make-up air for select BEST or Broan range hoods.
