Belimo FSAFB24-SR : Fail-Safe Fire & Smoke Actuator, 180 in-lb, 24VAC/DC, Modulating 2-10VDC Control Signal, 5-Year Warranty
Features:
- For dampers up to 16 sq.ft. and 2000 fpm at 350°F (177°C)
- UL 60730 or UL 873 listed
- UL 555 & UL 555S listed with all major damper manufacturers
- UL 2043 listed for use in plenums
Note: The discontinuation of the Classic FSAF series of actuators was replaced by the FSAFA series. Key improvements in the new actuators include increased torque (180 inch-pounds vs. 133), higher temperature ratings (350°F vs. 250°F), faster drive time, and improved spring time. The new actuator lacks a manual override but meets updated UL standards (60730) and remains compatible with existing damper systems.
