Greenheck Fan Combination Fire Smoke Damper FSD-211 - Manual (Page 6)

Actuators and Accessories
space envelopes
Externally mounted actuators always require space outside
of the damper sleeve. The “S” dimension illustrates the
clearance required for various available actuators.
On dampers less than 18 in. (457mm) high, actuators
may also require clearances above and/or below the
sleeve. “B” and “T” dimensions are worst case clearance
requirements for some dampers less than 18 in. (457mm)
high. All damper sizes under 18 in. (457mm) high do not
require these worst case clearances. If space availability
above or below the damper sleeve is limited, each damper
size should be individually evaluated.
damper sleeve dimensional data
The drawings below and corresponding table show the position of the FSD-211 damper when mounted in a factory sleeve.
The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for
installation of retaining angles and duct connections.
The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be
positioned at other locations within a range of 6 in. (152mm) to 12 in. (305mm) for the "A" dimension.
