This UL listed fusible link provides automatic closure of a damper
in case of fire to reduce draft and spread of smoke. The link melts
at 165° F to release a spring that forces the damper to fully
close AmeriFlow multi-valve registers.
Ceiling or Sidewall diffusers
can be ordered with the patented Fusible Link Assembly attached. For steel products, the assembly may be field installed with pop rivets.
The addition of the assembly does not restrict the use of the damper
and the overall depth of the assembly will not interfere with duct
work installation in 4" walls. Once activated, the assembly
must be replaced.
Available for models 356, 357, 382, 383, 384 and 413.
