WARNING!

Before replacing actuator, damper must be inspected and determined to be

fully functional. See NFPA 80 &/or NFPA 105 for recommended check list.

WARNING!

Installer must be trained and experienced with repair

of fire and smoke dampers and actuators.

UL®

Code and Standard Issues

In general, the administrative section of codes states that all mechanical and electrical systems

must be kept in working order and an individual section may state that all life safety devices

and systems must be operable. NFPA 80 (Fire) & NFPA 105 (Smoke) require periodic testing

and repair of dampers as soon as possible after any deficiency is uncovered. Required testing

is shown in the chart below.

Weekly self-test Not required

Fire & smoke dampers are appliances and field replacement of components is required when

failure of any component occurs.

The Authority Having Jurisdiction (local Fire Marshal and/or Building Official) must be consulted

if any blade or auxiliary switches are employed and are connected to the fire alarm system or

to a Fire Fighters Smoke Control System (FSCS) panel. Retesting is required. A permit and

inspection may be required since connections to an alarm system have been touched.

In the “Marking & Application Guide, Dampers for Fire Barrier and Smoke Applications &

Ceiling Dampers” April 2013 by Underwriters Laboratories Inc.®, page 6 they state:

DAMPER ACTUATORS

“… field mounting or substitution of actuators is not covered within the scope of the UL

certification of the product. However, this does not necessarily preclude replacement of

actuators in the field. Like any appliance, field servicing of these products is not covered

under the scope of the UL certification and factory follow-up service program. As with any

part of the damper, it is expected that replacement of actuators in the field be done in

accordance with the damper manufacturer’s normal field servicing program.”

Air Balance Honeywell ML&MS Types to Belimo FSxx March 2018 2

NFPA 80 (Fire) & NFPA 105 (Smoke )

See NFPA 80 & NFPA 105 for details. The damper cleaning and examination check list here is based

on them.

Damper installation shall meet code requirements. Fire stopping and drywall integrity shall be

confirmed. Damper blades shall be in plane of wall. Duct shall be fall away with no fasteners

connected to damper sleeve.

a. Dampers and ducts shall be cleaned of all foreign debris and dust build-up.

b. All exposed moving parts of the damper shall be dry lubricated as required by the

manufacturer. Do not use oil as it draws dirt.

c. Damper shall be examined without defective old motor or new actuator to determine:

i. The damper shall fully close from the open position.

ii. Damper shall fully open from the closed position.

iii. There are no obstructions to the operation of the damper. The damper shall not be

blocked from closure in any way due to rusted, bent, misaligned, or damaged frame

or blades. The damper shall not have defective hinges, side &/or blade seals, or

other moving parts. The damper frame shall not be penetrated by any foreign objects

that would affect operation.

d. If the damper is equipped with a fusible link, the link shall be removed for testing to ensure

full closure and lock-in-place if so equipped. If the link is damaged or painted, it shall be

replaced with a link of the same size, temperature, and load rating.

e. The fusible link shall be reinstalled after testing is complete.

After installation and wiring of new actuator it shall be tested.

a. The checklist may be customized using material here and in NFPA Standards. Multiple

geometric configurations of springs, fusible link, thermal sensor(s), and actuation are possible.

Confirm with AHJ if any additional requirements exist.

b. Electric thermal sensors, if present, must be tested and replaced if defective.

c. The test shall be conducted with normal HVAC airflow.

d. When equipped with smoke detection activation, the smoke detector shall be activated and

damper operation observed.

A record of all repairs must be kept on site and made available to AHJ.

NFPA requires damper inspection and repair of dampers.

See www.nfpa.org for Standards. Details not covered here.

Test voltage input to actuators and repair as necessary if voltage is not correct.

Old breakers often deliver below 115V and failed actuators may be due to power

supply problems.

Air Balance Honeywell ML&MS Types to Belimo FSxx March 2018 3

Local Code Approval

While it is not detailed in codes, the following rules should be followed for selecting Belimo

actuators for replacement:

Check the technical specifications to ensure an “equal or better” actuator is used.

•Temperature – the replacement actuator shall have been UL555S tested at the same or

better temperature as the original actuator. 250˚F or 350˚F are standard.

•Time – the replacement actuator shall drive open and spring closed at a speed equal or

faster than presently required by codes. (The AHJ may grant an exception and

“grandfather” slower actuators where the original actuator was slower.)

•Torque – replacement actuator shall have equal or greater torque than the failed

actuator.

•Voltage – replacement actuator shall have the same voltage rating as the original.

•Amperage – the replacement actuator(s) shall not draw more amperage than the

original(s) and cause the total connected amp draw on a circuit breaker to be greater

than allowed by electrical code.

•Final Testing – actuated damper and associated devices shall be tested for proper

operation. See Fire Marshal Notification Form on last page.

(Mnemonic device: TTT-VAT)

WARNING!

In all cases, installation must comply with any and all local electrical and life

safety codes. Operation of the system after installation must be performed to

verify proper damper cycling. Final checkout requires verifying correct function.

WARNING!

Disconnect and lock out power before starting to disconnect old motor.

NEGATOR SPRING DAMPERS

Where old negator spring damper motors were replaced by a Honeywell, the spring

should have been removed and a new thermal sensor installed. If this has not been

done, call Belimo for special instructions.

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.

Replacement Instructions

1. Disconnect power and wires from motor in wiring compartment.

2. Disconnect flex connection from actuator to mounting base.

3. Loosen set screws on shaft and 4 screws holding motor to base. Remove motor.

4. Several anti-rotation mounting scenarios are possible. See Mounting Methods below.

5. Mount Belimo FSLF or FSNF over shaft.

6. Connect anti-rotation strap.

7. Close damper tightly, tighten nuts on clamp.

8. Pull out old wires and pull Belimo wires thru flex. Cut off excess. Wire nut Belimo wires to

existing sensor wires.

9. Connect green ground on 120V models. Connect hot and neutral (or common if 24VAC).

See Wiring Methods below.

Conformance test required. See Fire Marshal form on last page.

Sheet metal holder bracket and

mounting plate.

This compartment does not have to be

opened except to reset sensor during

acceptance testing. The bracket does

not have to be removed from damper.

Shown here for instruction.

Four bolts hold actuator to

the mounting plate.

For short shaft mounting, the

ZG-LMSA-1/2-5 can be used. Alternately,

the clamp can be installed between the

actuator and sheet metal.

Air Balance Honeywell ML&MS Types to Belimo FSxx March 2018 9

Mounting Methods

Actuators are mounted on the sleeve of the damper in

some cases with a remote sensor and sometimes

within the sheet metal bracket shown below.

Belimo FSLF anti-rotation strap (yellow arrows). Shaft

adaptors and other mounting plates are available.

AF-P anti-

rotation strap.

Old

bracket

For small dampers where the

actuator must hang out in the air.

Alternatively,

reuse old

bracket

Bolts and

lock nuts.

In all cases, the stud of the anti-rotation strap should fit in the middle of the slot at the bottom of the

Belimo. This allows the actuator to move as necessary to compensate for any non-concentric

rotation of the damper shaft.

Typical External Mount

Note: short shaft.

Short Shaft Mounting

The Belimo clamp is very stable

when mounted between the actuator and

the supporting sheet metal.

After mounting, tighten the clamp

nuts with a 10mm, long-nosed, deep-well,

¼” drive socket.
