The FSTF series actuators were introduced in 2013. They are 18 in-lb and designed for
under 1.5 sq.ft. of fire and smoke damper. Use on larger dampers only when replacing
an existing FSTF on a fire and smoke damper.
The FSLF is recommended for small dampers.
Belimo actuators pass
UL555S at the same damper
sizes as the Honeywell.
NOTE. Although an actuator may operate a larger sized damper
use the UL listed sizing. Call for assistance.
