FS Series Fire and Smoke Actuation

Belimo is the worldwide leader in
fire and smoke actuation

Belimo first produced actuators for the European fire and smoke damper
market in 1978. Belimo has consistently offered new technology since
entering the market. Since 1978 Belimo’s market share has grown as
actuator variations were released to meet various worldwide requirements.
The FSLF and FSAF are the latest models to be introduced for the United
States and regions of the world requiring UL 555 and UL 555S listing.

Belimo is the dominant fire and smoke actuator manufacturer in
Europe today with 80% market share and is growing in the rest
of the world.

FS Series Fire and Smoke Actuation

The Belimo Difference

● Customer Commitment.

Extensive product range. Application assistance.
Same-day shipments. Free technical support. Five year warranty.

●

Low Installation and Life-Cycle Cost.

Easy installation. Accuracy and repeatability.
Low power consumption. No maintenance.

●

Long Service Life.

Components tested before assembly. Every product tested before shipment.
30+ years direct coupled actuator design.

A CLOSER LOOK…

● True mechanical spring return – the most reliable failsafe.

● Reverse mount for clockwise or counterclockwise fail-safe.

● Check damper position easily with clear position indicator.

● Overload-proof throughout rotation.

● Easy mechanical stop to adjust angle of rotation

(add ZDB-AF2 accessory/FSAF and FSNF only).

● Built-in auxiliary switch is easy to use, offers feedback

or signal for additional device. (-S models)

● Manual override crank speeds installation.

(only on FSAF models)

● The same 100% steel toothed cold-weld clamp that Belimo

uses on all actuators is used on the FS Series. No slipping
on damper shafts will occur.

● Tested at high torque load for a minimum of 20,000 cycles

per UL555(S).

● Reliable DC motor–low current draw.

● Permanently lubricated gears.

● FSNF and FSLF actuators meet Uniform Building

Code (UBC) requirements.

● Belimo actuator is silent when holding at end position.

Fire and smoke actuator, 133 in-lb, [15 Nm], spring return, meets 250°F [121°C] for half hour, 75 second

Torque min. 133 in-lb, for control of air dampers

Application

For two position control of UL555S rated dampers in
HVAC. Actuator sizing should be done in accordance with
the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft or jack­shaft 3/8” to 1.05” in diameter by means of its universal clamp.
A crankarm and mounting brackets are available if the actua­tor cannot be direct coupled to the jackshaft or damper shaft.

Square footage of damper operated will depend on make
and model of damper. Typically 12 sq.ft. minimum up to
24 sq.ft maximum will be operated for UL555S applications.

Operation

The FSAF series actuators provide true spring return
operation for reliable fail-safe application and positive close­off on UL555S dampers. The spring return system provides
constant torque to the damper with, and without, power
applied to the actuator.

The FSAF series provides 95° of rotation and is provided with
a graduated position indicator showing 0 to 95°. The FSAF
has a manual positioning mechanism which allows the setting
of any damper position within its 95° of rotation.

The actuator is shipped in the zero fail-safe position to pro­vide automatic compression against damper gaskets for tight
shut-off. When power is applied, the manual mechanism is
released and the actuator drives toward the
open position where it stops rotating.

The manual override can also be released physically by the
use of a crank supplied with the actuator.
