WARNING!

Installer must be trained and experienced with repair

of fire and smoke dampers and actuators.

WARNING!

Before replacing actuator, damper must be inspected and

determined to be fully functional. See NFPA 80 &/or NFPA 105 for

recommended check list.

UL®

Code and Standard Issues

In general, the administrative section of codes state 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.

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.”

Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015

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.

NFPA requires damper inspection and repair of dampers.

See www.nfpa.org. for Standards.

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.

Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015

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 Acceptance testing details below.

(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!

Note that where any fire alarm wiring is touched, the fire department

must be informed.

Cross Reference

MultiProducts

There is no one to one replacement. Rather, all the old linkage parts, external spring, and

motor are removed and the new actuator is direct coupled to the damper shaft. Double

check that the fusible link and shaft spring are intact. See BAE 165 below if not.

NOTE

Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015

Application

Greenheck used a dual spring approach. The external spring closes the motor.

A hidden internal spring is held back by a fusible link. It is not involved in the smoke

function and should not be changed.

The motors above are connected by linkage as shown in the photographs below. The

Belimo FSLF can be direct coupled if space exists for mounting. A bracket may have to

be fabricated from 16 ga. Sheet metal to hold the anti-rotation strap. The geometry of

the situation determines the mounting method.

Below and right. Black arrow

points to the 1/4” motor shaft

and spring. White arrow

points to the damper shaft

which is hidden.

Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015

View of damper frame, blade, and shaft. Detail of spring, arm, and fusible link.

RIGHT!

The Greenheck high temperature

damper closing is accomplished

with a fusible link and a shaft

spring.

Replace the fusible link if

necessary and test the closing

function.

THIS SPRING AND FUSIBLE

LINK MUST REMAIN IN PLACE.

WRONG!

This spring has been

disconnected from the linkage.

It must be repaired or the damper

replaced.

Test when reattached to ensure

the damper closes if fusible link

melts.

Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015

Spring. Motor is applied the

same as any linkage application.

Remove spring and actuator.

This shaft is not mounted to

the damper.

Crankarm is connected to the damper shaft. The

Belimo may be direct coupled over the shaft. For

short shaft mounting, place clamp of actuator

between actuator and damper. See p9.

If a linkage is needed due to space constraints,

use FSNF with ZG-AF or other linkage kit with

rod. See Mounting Methods Guide and

Mechanical Accessories Booklets at

www.belimo.us.
