TYPICAL REOPENABLE DAMPER with FSCS
Investigate cause of Honeywell failure. For example, was old external spring removed correctly?
Honeywell motor
was installed as a
retrofit on dampers
with fusible links.
There is no electric
sensor in the
damper in that case
as there is typically
a shaft spring
performing the fire
function. Wiring is
shown to right.
