Fire & Smoke damper actuator
Application
The type FSNF spring-return actuator is intended for the operation of smoke
and combination fire and smoke dampers in ventilation and air-conditioning
systems. The actuator will meet requirements of UL555 and UL555S when
tested as an assembly with the damper and will meet requirements of UBC for
15 second opening and closing at 350°F. Square footage of damper operated
will depend on make and model and the temperature required.
IMPORTANT 24VDC NOTE: The FSNF24 & -S models will not operate below
24VDC. A filtered and regulated power supply must be used.
Operation
Mounting of the actuator to the damper axle shaft or jackshaft (3/8” to 1.05”) is
via a cold-weld clamp. Teeth in the clamp and V-bolt dig into the metal of both
solid and hollow shafts maintaining a perfect connection. The specially designed
clamp will not crush hollow shafts. The bottom end of the actuator is held by an
anti-rotation strap or by a stud provided by the damper manufacturer.
The actuator is mounted in its fail safe position with the damper blade(s) closed.
Upon applying power, the actuator drives the damper to the open position. The
internal spring is tensioned at the same time. If the power supply is interrupted,
the spring moves the damper back to its fail-safe position.

Safety Notes
* Neither UL nor Belimo require local over-current protection. The FSNF
actuators draw higher peak current when driving against any type of stop. If
used, this requires the value of a local fuse or breaker to be increased to avoid
nuisance opening or tripping. A 2.5 amp slow blow should be used for 24VAC.
A 0.5 amp slow blow should be used for 120 VAC. A 0.25 amp slow blow
should be used for 230V and a 0.3 amp slow blow for 208 VAC. Transformers:
Note that while a 24V 100VA transformer would handle 2 actuators, a 4 A
breaker or plug fuse is insufficient. A 5 amp slow blow would be required.
Belimo Fire & Smoke actuators have passed the AMCA 520 and UL 555S Long
Term Holding test. No special cycling is required during prolonged periods
when actuator is driven open and held there. Periodic testing of dampers and
actuators per local codes and NFPA 80 and NFPA 105 are required.
The actuator contains no components which the user can replace or repair.
A 1/2” threaded connector is standard. FSNFxx-FC models have a 3/8” Flex
Connector. Other than the connector, these actuators are identical to the
conduit connector version.
