APPLICATION

Model FSD-211 is a combination fire smoke damper with 3V style

blades. The FSD-211 has been qualified to 2000 fpm (10.2 m/s) and

4 in. wg (1 kPa) for operation and dynamic closure in emergency fire

smoke situations. Model FSD-211 may be installed vertically (with

blades running horizontal) or horizontally and is rated for airflow and

leakage in either direction.

Pressure Drop Data FSD-211 This pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of .075 lb/ft3 (1.201 kg/m3). Actual pressure drop found in any HVAC system is a combination of many factors. This pressure drop information along with an analysis of other system influences should be used to estimate actual pressure losses for a damper installed in a given HVAC system.

Application Data 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.
