These instructions cover the installation of CFSD-XXX
leakage rated combination fire/smoke dampers with
factory installed actuators and sleeves in corridor
ceiling applications. These instructions meet the
requirements of UL555, UL555S and the Uniform
Building Code.
There are three different configurations available for
this application. Configurations 1 & 2 apply when the
fire rated ceiling is also the finished ceiling and the
damper is installed behind a grille, register or diffuser.
Configuration 3 applies when the fire rated ceiling is
above the finished ceiling and the grille, register or
diffuser is somewhere below the corridor damper.
1. MAXIMUM SIZES
Corridor dampers have a maximum size of
24 in. W x 24 in. H (610mm x 610mm) and a
minimum size of 8 in. W x 6 in. H. (203mm x
152mm).
2. CLEARANCES REQUIRED BETWEEN CORRIDOR
DAMPER SLEEVES AND CEILING OPENINGS
The interior dimension of the prepared ceiling
opening
should be 1/4 in. (6mm) larger than the overall size
of the damper and sleeve assembly.
These are total clearances (ignoring fastener
heads) and do not need to be spaced equally
around the damper.
3. SECURING CORRIDOR DAMPER SLEEVES TO FIRE
RATED CEILING OPENINGS
Corridor damper and sleeve assemblies must
be installed in fire rated ceiling openings using
retaining angles on each side of the ceiling as
described below:

Damper Maintenance
6
Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary,
use mild detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft
bearings and jamb seals, do not use oil-based lubricants or any other lubricants that attract contaminants such
as dust.
Dampers and their actuator(s) must be maintained, cycled, and tested a minimum in accordance with:
• The latest editions of NFPA 80, 90A, 92A, 92B, 101, 105, UL864, AMCA 503-03 and local codes.
• Actuator manufacturer recommendations.
Damper Troubleshooting
The following is a possible cause and correction list for common concerns with the dampers.
Symptom Possible Cause Corrective Action

Pre-Installation Guidelines
The basic intent of a proper installation is to secure the
fire or fire smoke damper in, not to, the opening in such a
manner as to prevent distortion and disruption of damper
operation. This is accomplished by allowing the fire or fire
smoke damper in rated separation openings to expand
and for the connecting duct to separate in the event of the
collapse of the hanging system. The following items will
aid in completing the damper installation in a timely and
effective manner.
1) Check the schedules for proper damper locations
within the building. Visually inspect the damper for
damage and verify that the Reusable Resettable Link
(RRL) is in place or has not activated. Never install a
fire damper without the proper UL approved RRL in
place. (RRL is standard control option. These electric
links have a button for resetting.) If damper is furnished
with fusible link, visually inspect the link to verify its not
missing or broken. Replace link as necessary.
2) Lift or handle damper using sleeve or frame. Do not lift
damper using blades or actuators.
3) Damper has label on outside of sleeve indicating a
‘No Screw’ area. Do not install screws into this area as
screws may interfere with unexposed blade linkage and
prevent damper blades from opening and/or closing.
4) Damper has label indicating position of damper
and sleeve assembly in the wall. Install accordingly
to comply with manufacturer’s appropriate UL
Classification file number.
5) Damper must be installed into duct or opening square
and free of twist or other misalignment. Damper must
not be squeezed or stretched into duct or opening. Out
of square, racked, twisted or misaligned installations
can cause excessive leakage and/or torque
requirements to exceed damper/actuator design.
6) Damper and actuator must be kept clean and
protected from dirt, dust and other foreign materials
prior to and after installation. Examples of such foreign
materials include but are not limited to:
a) Mortar dust
b) Drywall dust
c) Firesafing materials
d) Wall texture
e) Paint overspray
7) Damper should be sufficiently covered as to prevent
overspray if wall texturing or spray painting will be
performed within 5 feet of the damper. Excessive dirt
or foreign material deposits on damper can cause
excessive leakage and/or torque requirements to
exceed damper/actuator design.
8) Caulking is not necessary, nor is it allowed, between
the damper sleeve and the wall or floor opening
(annular space). However, caulking may be applied to
the retaining angles.
9) ACCESS: Suitable access (such that RRL’s and
actuators can be maintained, etc.) must be provided
for damper inspection and servicing. Where it is not
possible to achieve sufficient size access, it will be
necessary to install a removable section of duct. (Refer
to NFPA 90A).
10) The Code Authority Having Jurisdiction (AHJ) must
evaluate and provide approval of final installation
where variations to these instructions are necessary.
Electrical Guidelines

These instructions apply to 1
masonry, block or stud walls and 2) concrete floors or ceilings. Specific requirements in these instructions are mandatory. Dampers
must be installed in accordance with these instructions to meet the requirements of UL 555 and UL 555S. The installation of the
damper and all duct connections to the damper sleeve shall conform to the latest editions of NFPA 90A, Standard for the
Installation of Air Conditioning and Ventilating Systems, and the SMACNA Fire, Smoke and Radiation Damper Installation
Guide, and UL Classifications R13317.
Note: Combination fire smoke dampers are manufactured and labelled for either vertical or horizontal installation. The
dampers must be installed in accordance with labelling.
1. CLEARANCES REQUIRED BETWEEN FIRE DAMPER
SLEEVES AND WALL/FLOOR OPENINGS
Fire damper and sleeve assemblies expand during periods
of intense heat. Therefore, it is essential that openings in
walls or floors be larger than the fire/smoke damper and
sleeve assembly to allow for this expansion. Minimum
clearances required between the outside of fire damper
sleeve assemblies and wall/floor openings are:
• Galvanized steel fire dampers and sleeves: 1⁄8 in. per
foot (3mm per .3 m) of damper width and
(3mm per .3 m) height with a minimum clearance of
(6mm), maximum of 1 1⁄2 in. (38mm).
Recommended clearances, for width and/or height
dimensions of:
1) 48 in. (1219mm) or less:
/2 and 3 hour rated combination fire smoke dampers mounted (blades must be horizontal) in: 1)
2) More than 48 in. (1219mm) and 96 in. (2438mm) or

4. SECURING THE DAMPER/SLEEVE ASSEMBLY TO
WALL AND FLOOR OPENINGS (for single side retaining
angle instructions, see supplements)
Damper/sleeve assemblies must be installed in wall and
floor openings using retaining angles on at least one side
of the wall or floor as described below:
• Retaining angles for 1½ hour rated dampers with a
width and height 48 in. (1219mm) or less must be a
minimum of 20 ga. (1mm). Retaining angles for all 3 hour
rated dampers and all dampers with a width or height
greater than 48 in. (1219mm) must be a minimum of 16
gauge (1.5mm). The leg of the retaining angle on the
damper sleeve shall be a minimum of 1¼ in. (32mm).
The leg of the retaining angle on the wall/floor shall be
long enough to cover the annular space and overlap the
wall/floor by a minimum of 1 in. (25mm).
• Retaining angles must be attached to the damper using
one or more of the following methods of attachment
(refer to label on outside of sleeve for ‘No Screw’ area):
• Tack or spot welds
• #10 (3/4 in. [19mm] max.) sheet metal screws
1
•
/4 in. (6mm) bolts and nuts
3
•
/16 in. (5mm) steel pop rivets
A minimum of two connections per side, top, and bottom,
12 in. (305mm) O.C. maximum for openings of
48 in. W x 36 in. H (1219mm x 914mm) and less, and 6 in.
(152mm) O.C. for openings 80 in. W x 50 in. H
(2032mm x 1270mm), 50 in. W x 72 in. H (1270mm x
1829mm), and 40 in. W x 72 in. H (1016mm x 1829mm)
or less. The angles must be attached to all 4 sides of the
sleeve. Ensure that attachment device does not interfere
with the operation of the damper and the free movement
of the damper blades. The angles need not be attached
to each other at the corners. Do not secure the retaining
angle to the fire separation (see Fig. 3).
• Retaining angles should not be fastened to the wall/
floor material. The angles should only sandwich the
wall/floor and allow for damper expansion during
periods of intense heat.

5. ACTUATOR CONNECTIONS
Electrical and/or pneumatic connections to damper
actuators should be made in accordance with wiring and
piping diagrams developed in compliance with applicable
codes, ordinances and regulations (see Electrical
Guidelines).
6. INSTALLING MULTIPLE DAMPER SECTION
ASSEMBLIES
A damper assembly is not restricted to a maximum
number of sections, but must not exceed the section
sizes and overall sizes shown (see chart).
Two section high dampers require reinforcement using a
14 gauge (2mm), 5 in. (127mm) wide mullion as shown in
Fig. 4 below, or two individually sleeved units stacked
vertically, shown below in Fig. 5. When using two
individually sleeved units, the sleeve acts as the mullion,
therefore no mullion is required.
The damper sections must be attached together with
#10 (3/4 in. max. [19mm]) sheet metal screws, 1/4 in. (6mm)
diameter nuts and bolts, tack or spot welds, or 3/16 in.
(48mm) diameter steel pop rivets. Attachments must be
spaced a maximum of 6 in. (152mm) on centers and a
maximum of 2 in. (51mm) from corners. Attachments must
be made on front face and back face (air entering and air
exiting side) of damper sections.
Note: Dampers ordered for individual installation may
not be installed together. The full assembly size must be
specified at the time the dampers are ordered.

7. CONNECTION AND OPERATION OF TEMPERATURE
12
RESPONSE DEVICES (RRL STANDARD, OCI OPTION,
AND TOR OPTION)
RRL - Dampers will be supplied with a thermostat-type
temperature response device, as a standard. The device
is a RRL (resettable link device), which only incorporates
one thermostat and therefore the damper remains
closed as soon as its sensor temperature is reached.
The RRL does not contain blade indication switches.
Refer to Fig. 6 for wiring of the RRL thermostat.
Fig. 6 RRL Wiring
OCI - The OCI (open or closed indicator) option
contains a single pole, double throw switch used
to indicate the damper blade position. The switch
provides a positive open or closed signal when used in
conjunction with remote indicator lights. Refer to Fig. 7
& 8 for wiring of the OCI option.
TOR - The TOR (temperature override device) option
incorporates two thermostats with fixed settings (usually
165°F [74°C] and 350°F [177°C]). The primary sensor
(the sensor with the lower temperature setting) can be
bypassed by an external electrical signal allowing the
damper to reopen until the temperature reaches the
setting of the secondary sensor (the sensor with the
higher temperature setting).
See Fig. 8.
When the temperature of the secondary sensor is
exceeded the damper closes and remains closed
thereafter.
The TOR assembly also contains a single pole, double
throw switch used to indicate damper blade position. The
switch provides a positive open or closed signal when
used in conjunction with remote indicator lights. See
Fig. 8 for wiring of the TOR thermostats and indicator
switches.
If either the TOR or the RRL is ordered with a pneumatic
actuator, an EP switch is required with an appropriate
electric power circuit to allow the electric thermostat to
control the pneumatic actuator.
Fig. 7 OCI Wiring
Fig. 8 RRL/OCI Wiring
Fig. 9 TOR Wiring
PRV - The PRV (pneumatic relief valve) option is heat
responsive device used with pneumatic actuators. This
can be used in place of EP switch where a RRL is used.
The PRV activates when temperature in excess of the
temperature of the fusible link are detected. When the
fusible link melts, air from the actuator is exhausted to
close the dampers. Pneumatic actuators are to be piped
per local code.

Damper Maintenance
15
Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use mild
detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings and jamb seals, do
not use oil-based lubricants or any other lubricants that attract contaminants such as dust.
Dampers and their actuator(s) must be maintained, cycled, and tested a minimum in accordance with:
• The latest editions of NFPA 80, 90A, 92A, 92B, 101, 105, UL864, AMCA 503-03 and local codes.
• Actuator manufacturer recommendations.
