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.

●

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.

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.

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.

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.

Accessories

All AF/NF linkages and parts may be employed.

Blank-off Channel

Use of blank-offs between damper sections to

The typical fire and smoke damper requires from 5-15 in-lb of torque per square foot at 250°F - 350°F under dynamic load (2400 fpm velocity). The FSNF will operate multi-section

dampers using multiple actuators for multiple sections. Some of the methods used are shown left.

Multi-section damper assemblies – typical applications

Caution must be used when replacing failed motors with new Belimo actuators. Many old motors did not have internal springs and depended on external springs on the side of the damper or wrapped around the damper shaft to close the damper.

In some cases, the damper must be replaced because the damper would have to undergo major modifications to replace an actuator.

In many cases, replacing the actuator voids the UL555S listing of the damper.

No ground on 24 V models.

Smoke Control and Combination Fire and Smoke Control Damper Actuators

All smoke and combination fire and smoke dampers shall be provided with Belimo FSLF, FSNF, or FSAF actuators. No substitutions allowed.

Damper and actuator shall have UL555S Listing for 250°F (350°F) and shall comply with UBC if required by local codes.

Where proof of closure switches are required, blade switches, actuator auxiliary switches, or proximity switches are allowed.

Typical specification

This is a direct coupled actuator. If linkages are needed use the FSNF series. Square shaft adaptors are available: 22153-00002, 22153-00003, 22513-00004 for the 8mm, 10mm, and 12mm, form fit respectively.

Safety note: 1/2" Threaded Connector

Screw a conduit fitting into the actuator’s metal bushing. Jacket the actuator’s input wiring with suitable flexible conduit. Properly terminate the conduit in a suitable junction box.

3/8" Flexible Connector Models (-FC Screw Connector)

Mount the flexible conduit into the actuator’s metal bushing by means of the provided screw with a torque of 1.2 Nm. Jacket the actuator’s input wiring with suitable flexible conduit. Properly terminate the conduit in a suitable junction box.

Replacement applications

The number one "equal or better" requirement for use as a replacement for obsolete defective motors is the UL555S listing of the Belimo actuator with the damper for the application. The local authority having jurisdiction sets the requirements. In some cases a permit and inspection may be required.

Contact Belimo for a list of damper manufacturers with UL555S listing with Belimo FSAF, FSLF, & FSNF actuators.

Fire and smoke spring return actuators FSNF230 (-S) US, FSNF24 (-S) US

70 in-lb [7.9 Nm], spring return, 350°F [177°C] for limited time, nominal 15 sec. operation

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. Square footage of damper operated will depend on make and model and the temperature required.

Operation

Mounting of the actuator to the damper 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.

Accessories

All AF/NF linkages may be applied. Order part 22965-00001 for square shafts.

The typical US fire-smoke damper requires from 5-15 in-lb torque per square ft. [6-17 Nm per square meter] at 350°F [171°C] under dynamic load (2400 fpm [12m/s] velocity).

Some of the methods used for multi-section dampers with the FSNF actuators are shown to the left.
