Ceiling Radiation Damper
For areas where local codes require fire dampers for compliance
with National Fire Protection Standard 90A, YORK® by Johnson
Controls offers a UL approved damper, UL555C, (CABS), file
#R8039. The dampers are rated for 3 hours and are activated
at 165°F. Compact in design, the dampers add only 7" in height
when mounted between the fan and the grille. Static pressure
created by the damper is negligible.
