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.

These instructions apply to 11/2 hour rated combination fire smoke dampers mounted (blades must be vertical) in: masonry,
block, or stud walls. Specific requirements in these instructions are mandatory. Dampers must be installed in accordance with
these instructions to meet the requirements of UL555 and UL555S. 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.
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 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.
Recommended clearances, for width and/or height
dimensions of:
1) 36 in. (914mm) or less: 1⁄2 in. (13mm) clearance
These are total clearances (ignoring fastener heads) and do
not need to be equally spaced around the damper.
2. SLEEVE LENGTH AND WALL THICKNESS
Insert the sleeved damper assembly into the prepared
opening, to appropriate depth (refer to label on outside
of sleeve for location of damper in wall; see Dimension A
and Detail 1, Fig. 1).
Recommended maximum and minimum insertion depth
can be exceeded if:
1) The operation of the damper is not impeded and
2) The CL of the damper frame remains within the plane of
3) Attachments made through the retaining angle do
IMPORTANT SAFETY DANGER! : To avoid causing
death or serious bodily harm to building occupants, do
not penetrate the ‘No Screw’ area designated on the
damper sleeve or the damper may not close properly.
The sleeve may extend a maximum of 16 in. beyond the
wall on the actuator side of the damper and a maximum
of 6 in. on the opposite side. Recommended standard
sleeve lengths for various wall thicknesses are:
(3mm) per foot of damper width and height with a
minimum clearance of 1⁄4 in. (6mm), maximum of 1 1⁄2
in. (38mm).

piping diagrams developed in compliance with applicable
codes, ordinances and regulations (see Electrical
Guidelines).
Page 5
6. CONNECTION AND OPERATION OF TEMPERATURE
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.
4 for wiring of the RRL thermostat.
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. 5 & 6 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°]). 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). When the temperature of the
secondary sensor is exceeded the damper closes and
remains closed thereafter (Figure 7).
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. 7 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.
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
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
Damper does not fully
open and/or close
RRL or TOR sensor
tripped
Damper does not operate
Frame is 'racked' causing blades to bind
on jamb seals
Actuator linkage loose Close damper, disconnect power, adjust and tighten
Defective motor Replace
