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.

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
d ith th d f t ’ l fi ld i i ”

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.
For the Air Movement and Control Association damper maintainance manual go to:
http://www.amca.org/publications/damper_maintenance.aspx
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.
Gear Train Motors and Linkages - Replacements with Belimo 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 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.

Examples of various gear train motors and mounting
In general, oil-filled spring return motors like the MA418 are
straightforward replacements. In this case, the Belimo FSNF or FSAF
may be direct coupled. The shaft spring should be examined and
exercised to prove it is still operational. The fusible link cannot be seen,
however it should release the shaft spring.
Gear Train Motors and Linkages - Replacements with Belimo March 2018 9

The above applications will need linkages due to space constraints or accessibility
ZG-AF US kit. This contains parts for several different ways to linkage the FSAF and
FSNF series of actuators.
Gear Train Motors and Linkages - Replacements with Belimo March 2018 10

Linkage Mounting
Apply the most appropriate linkage mounting method for the geometric
arrangement
WARNING!
USE CAUTION!
Springs are under high torsion and may cause serious injury! If any external
springs are present, exercise caution – wear face and hand protection.
Gear Train Motors and Linkages - Replacements with Belimo March 2018 11

Use of ZG-106 bracket with crank arm and ball joints to
connect to two damper arms.
With no space to direct couple, the ZG-AF Leg kit has
been used. Note the legs between actuator and duct
Above are some ways in which Belimo linkages are used. The lower right
picture is of an FSTF with ZG-TF112. This actuator is not generally used
for retrofits as it is only 18 in-lb of torque, but in special circumstances, it is
quite useful.
MA418 that was formerly
linkaged, now direct
coupled
These are very easy to
replace. Simply remove
the old motor and
linkages. Then mount
Belimo FSNF over shaft.
Do not remove any
bearings.
Gear Train Motors and Linkages - Replacements with Belimo March 2018 12

The FSAF*A and FSNF series may be mounted using the ZG-102 (left).
However, it is recommended that they be mounted on the ends of the
jackshaft (right). Derate torque to 80% of the combination of multiple
actuators.
NO.
Use of the ZG-102 for mounting 2 FSNF is not recommended in general. The
fast speed and high torque loads will damage gears if actuators are cycled
more than once a day.
YES.
Mounting FSNFs on the ends of the same
jackshaft is preferred. Alternately, the
jackshaft can be cut and the one actuator,
one damper section approach taken.
Example of linkage that can be replaced by direct coupling
The motor to the right can
be replaced by direct
coupling over the shaft.
Use of linkages is not
needed.

FSLF
The FSLF has no linkages except for a custom one supplied in a kit by Ruskin.
Ruskin makes a kit with a shaft
adaptor, hold down, and Belimo
FSLF120 actuator.
Fusible rods are no longer
available from Ruskin.
Where springs are defective, ball
joints, rod, and a BAE 165 or
Ruskin EFL are necessary.
Rewiring is necessary.
Gear Train Motors and Linkages - Replacements with Belimo March 2018 16

FSTF mounting
Given the typical space constraints of installed dampers, it is likely that all the actuator
and linkage parts will need to be assembled as much as possible and then installed as
an assembly.
Possible alternate arrangements for damper clip. (FSNF, FSAF actuators shown.)
Gear Train Motors and Linkages - Replacements with Belimo March 2018 17

FSTF linkage kit mounting
The crank arm material is Duroplast Vyncolit® (phenolic compound similar to Bakelite).
Smoldering temp is 500°F; auto-ignition temp is 900°F.
The ZG-TF112 Crank Arm Adaptor Kit includes:
1 ZG-113 Mounting Bracket
1 KH-TF-1 Crank arm with Retaining Clip
2 Bolts with Nuts

Direct Coupling
This is the preferred method for mounting -
FSLF
Note that actuator floats freely. Clamp cold welds
when teeth dig into the damper shaft and the anti-
rotation strap stud allows the actuator to move if
shaft is not perfectly concentric. Rigid mounting by
jamming the stud into the U-slot of actuator is NOT
usually best.
FSLF mounted on the
damper shaft. Two
sheet metal screws hold
the anti-rotation strap.
Two nuts secure cold-
weld clamp onto shaft.
Gear Train Motors and Linkages - Replacements with Belimo March 2018 19

FSNF & FSAF
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.
Clamp
The geometry of linkages changes the torque translation between the actuator and the
damper. See Belimo’s Mounting Methods Guide for a description of the mathematics.
As long as it is mechanically
solid, the anti-rotation strap
may be bent to fit height.
