Fire
Dampers are typically intended to be used as part of the HVAC
duct system when passing through a fire rated barrier (walls,
partitions, floors). The trigger mechanism is a heat fusible
link that when activated, impedes the migration of high temperatures
into and through the duct system.
UL,
AMCA and Damper Manufacturers Require "once every 6 months"
Damper/Actuator cycling to ensure proper operation of fire/smoke
and smoke rated Dampers during a Fire event.
Fusible
links
Fusible
links are temperature sensitive fire protection devices designed
to be part of a fire protection system. The system is activated
when the ambient temperature increases to the point that causes
the fusible link to "break-apart". At the point of
breakage, it releases the pre-loaded fire protection device,
thus restricting the spread of fire.
