Important General Notes:When UL is referred to in this document, it represents UL/ULC. This installation instruction applies to Combination Fire/Smoke Dampers (3V, Airfoil, Parallel, Opposed, Single, and Multi-blade types) mounted in the plane of an UL approved fire partition. Combination Fire /Smoke Dampers are approved for use in Static or Dynamic Systems. The dampers are designed for operation in the vertical or horizontal position with blades running horizontal. The dampers are to be installed square and free from twisting or racking. The dampers shall not be compressed or stretched into the opening.

Transportation and installation of the dampers shall be handled with the sleeve or frame. Do not lift the damper with the blades or actuator. Special care shall be given to the damper before installation and after to insure it is protected against dirt, weather, mortar and drywall dust, wall texture and paint. Any of these conditions could cause the damper not to operate correctly and void the warranty. Suitable access to inside duct is to be provided for inspection and replacement of parts such as heat response devices and actuators per NFPA 90A and local authority having jurisdiction. The need to seal the damper in the penetration is not required by Underwriters Laboratories. PRICE dampers have been tested and approved to be mounted without the use of sealants around the perimeter space between the damper and the penetration. As with all joints, contractor must seal duct-collar connections in the field after installation.

4. Methods of Securing Damper in Opening:

a. Two Angle (Two Sided) Method: This method is the oldest and most commonly used. This method is approved for use in UL approved concrete/masonry partitions, steel stud/gypsum walls, and wood stud/gypsum walls. In this method 2 sets of angles are used to secure the damper in the opening, one on each side of the partition (See Fig. 7). Two Angle Method is approved for 11/2 and 3 hour dampers, vertical or horizontal orientation, and any maximum size multi-section UL approved damper (see Underwriter’s Laboratories Listings for maximum assembly sizes). Angles shall be a minimum of 11/2“ x 11/2 “ (38mm x 38mm) x 16 gauge. Angles are to be fastened to the sleeve on 6" (152mm) centers with #10 (M5) sheet metal screws, 3/16" (5mm) steel pop rivets, 1/2“ (13mm) tack welds, or 1/4“ (6mm) diameter nut and bolts with not more than 2" (51mm) from each end with a minimum of two connections per side/leg. The angles are to overlap the partition a minimum of 1" (25mm). These angles may be of a unit type construction and may or may not be fastened to each other at the corners. When the duct work terminates at the damper or installation prohibits angles from turning out/away from the wall, the retaining angle shall be reversed (leg turned into the opening) providing the size of the opening is increased by an amount equal to twice the combined thickness of the angle and the height of the screw or bolthead to maintain expansion clearances. See note 1A for information on clearances. See Fig. 7 for detailed drawings of installations.b. One Angle (Single Sided) Method: In this method 1 set of angles are used to secure the damper in the opening. This method is approved for use in UL approved concrete/masonry partitions and steel stud/gypsum walls. Only one side of the fire partition will have the angles installed (see Fig. 8). One Angle Method is approved for 11/2

hour dampers only, vertical and horizontal (angles on top side only) orientations, and the maximum size shall be 108” wide or 108” high (2743mm x 2743mm) up to 36 square feet and up to the maximum multi-sectionUL approved damper size (see Underwriter’s Laboratories Listings for maximum assembly sizes). Angle shall be a minimum of 11/2” x 11/2” (38mm x 38mm) by 16 gauge. Angles are to be fastened to the sleeve on 6” (152mm) centers with #10 (M5) sheet metal screws, 3/16” (5mm) steel pop rivets, 1/2” (13mm) tack welds, or 1/4” (6mm) diameter nut and bolts with not more than 2” (51mm) from each end with a minimum of two connections on each side/leg top and bottom. The angles are also to be fastened to the fire partition with: in concrete/masonry partitions with #10 (M5) self-tapping concrete anchors or

concrete screws on 6” (152mm) centers and must engage the fire partition a minimum of 11/2” (38mm); in steel stud/gypsum partitions secure the angles to the partition with #10 (M5) screws long enough to penetrate the J-Runners and E-Stud by a minimum of 3/8” (10mm). Use a minimum of two fasteners per side. The angles are to overlap the partition a minimum of 1” (25mm). These angles may be of a unit type construction and may or may not be fastened to each other at the corners. When the duct work terminates at the damper or installation prohibits angles from turning out/away from the wall, the retaining angle shall be reversed (leg turned into the opening) providing the size of the opening is increased by an amount equal to twice the combined thickness of the angle and the height of the screw or bolt head to maintain expansion clearances. Angles can be placed in front of or behind the drywall attaching directly to the steel studs or masonry. PRICE’s Frame Retaining Angles (FRA) can be used in place of the angle mentioned above. See note 1B for information on clearances. See Fig. 8 for detailed drawings of installations.c. No Angle Method: In this method No angles are used to secure the damper in the opening. This method is approved for use in UL approved concrete/masonry partitions and steel stud/gypsum walls. This method uses a minimum 3/4” (19mm) flange is on one end of the sleeve. The damper/sleeve assembly is placed in the opening so that the flange rest flush up to the partition, then the fasteners are placed through the sleeve into the partition (see Fig. 9). No Angle Method is approved for 11/2 hour dampers only, vertical

and horizontal (flange on top side only) orientations, and the maximum size shall be 42” (1067mm) wide by 48” (1219mm) high up to the maximum multi-section UL approved damper size (see Underwriter’s Laboratories Listings for maximum assembly sizes). The sleeve flange shall be a minimum of 3/4” (19mm) high by 20 gauge steel. If a flange/angle is added, it shall be a minimum of 1” x 1” (25mm x 25mm) by 18 gauge steel and fastened with #10 (M5) bolts or screws, 1/2” (13mm) welds, or 3/16” (5mm) rivets to the sleeve, at a maximum spacing of 6” (152mm) o.c., not more than 2” (51mm) from each end with a minimum of two fasteners per side. The sleeve is to be fastened to the fire partition with: in concrete/masonry partitions with #10 self-tapping concrete anchors or concrete screws on 6” (152mm) centers and must engage the fire partition a minimum of 11/2” (38mm); in steel stud/gypsum partitions secure the angles to the partition with #10 (M5) screws long enough to penetrate the J-Runners and E-Stud by a minimum of 3/8” (10mm). Use a minimum of two fasteners per side. The sleeve flange can be placed in front of or behind the drywall attaching directly to the steel studs or masonry. Be sure to not stretch the damper when securing it into the partition. Stretching the damper can cause it to bind up and prevent it from operating properly. PRICE’s Frame Retaining Angles (FRA) can be used in place of the angle mentioned above. See note 1C for information on clearances. See Fig. 9 for detailed drawings of installations.

This method is approved for use in UL approved concrete/masonry partitions and steel stud/gypsum walls. This method uses a minimum 3/4” (19mm) flange is on one end of the sleeve. The damper/sleeve assembly is placed in the opening so that the flange rests flush up to the partition, then the fasteners are placed through the sleeve into the partition (see Fig. 6). No Angle Method is approved for 11/2 hour damp-ers only, vertical and horizontal (flange on top side only) orientations, and the maximum size shall be 42” (1067mm) wide by 48” (1219mm) high up to the maximum multi-section UL approved damper size (see Underwriter’s Laboratories Listings for maximum assembly sizes). The sleeve flange shall be a minimum of 3/4” (19mm) high by 20 gauge steel. If a flange/angle is added, it shall be a minimum of 1” x 1” (25mm x 25mm) by 18 gauge steel and fastened with #10 (M5) bolts or screws, 1/2” (13mm) welds, or3/16” (5mm) rivets to the sleeve, at a maximum spacing of 6” (152mm) o.c., not more than 2” (51mm) from each end with a minimum of two fasteners per side. The sleeve is to be fastened to the fire partition with: in concrete/ masonry partitions with #10 self-tapping concrete anchors or concrete screws on 6” (152mm) centers and must engage the fire partition a minimum of 11/2” (38mm); in steel stud/gypsum partitions secure the angles to the partition with #10 (M5) screws long enough to penetrate the J-Runners and E-Stud by a minimum of 3/8” (10mm). Use a minimum of two fasteners per side. The sleeve flange can be placed in front of or behind the drywall attaching directly to the steel studs or masonry. Be sure to not stretch the damper when securing it into the partition. Stretching the damper can cause it to bind up and prevent it from operating properly. PRICE’s Frame Retaining Angles (FRA) can be used in place of the angle mentioned above. See note 1 for information on clearances. See Fig. 6 for detailed drawings of installations.

b. Continuous Duct Method: In this method 1 set of angles are used to secure the damper in the opening. This method is approved for use in UL approved concrete/masonry partitions and steel stud/gypsum walls. Only one side of the fire partition will have the angles installed (see Fig. 7). One Angle Method is approved for 11/2 hour dampers only, vertical and horizontal (angles on top side only) orien-tations, and the maximum size shall be 42” wide x 48” high (1067mm x 1219mm) and up to the maximum multi-section UL approved damper size (see Underwriter’s Laboratories Listings for maximum assembly sizes). Angle shall be a minimum of 11/2” x 11/2” (38mm x 38mm) by 16 gauge. Angles are to be fastened to the sleeve on 6” (152mm) centers with #10 (M5) sheet metal screws, 3/16” (5mm) steel pop rivets, 1/2” (13mm) tack welds, or 1/4” (6mm) diameter nut and bolts with not more than 2” (51mm) from each end with a minimum of two connections on each side/leg top and bottom. The angles are also to be fastened to the fire partition with: in concrete/masonry partitions with #10 (M5) self-tapping concrete anchors or concrete screws on 6” (152mm) centers and must engage the fire partition a minimum of 11/2” (38mm); in steel stud/gypsum partitions secure the angles to the partition with #10 (M5) screws long enough to penetrate the J-Runners and E-Stud by a minimum of 3/8” (10mm). Use a minimum of two fasteners per side. The angles are to overlap the partition a minimum of 1” (25mm). These angles may be of a unit type construction and may or may not be fastened to each other at the corners. When the duct work terminates at the damper or installation prohibits angles from turning out away from the wall, the retaining angle shall be reversed (leg turned into the opening) providing the size of the opening is increased by an amount equal to twice the combined thickness of the angle and the height of the screw or bolt head to maintain expansion clearances. Angles can be placed in front of or behind the drywall attaching directly to the steel studs or masonry. PRICE’s Frame Retaining Angles (FRA) can be used in place of the angle mentioned above. See note 1 for information on clearances. See Fig. 7 for detailed drawings of installations.

4. Actuator Connections (if applicable):Electrical and/or pneumatic connections to damper actuators (if provided) should be made in accordance with wiring and piping diagrams developed in compliance with applicable codes, ordinances and regulations.

Horz. to Vert.Mullion Cap

C-C (Typical)

These installation instructions apply to the fabrication and construction of generic sup-port mullions. Support mullions are neces-sary whenever fire dampers are installed into an opening that is larger than the largest UL rated size for that damper. The mullions allow construction of a fire barrier that is larger than the maximum available size.

The opening must not exceed 120" (3048mm) high, but can be any width provided a verti-cal support mullion is used a maximum of every 120" (3048mm).

To properly use support mullions they must be fabricated and installed according to these instructions.

This generic support mullion is permitted by UL to only be used in static systems. A static system is one in which the fan shuts down in the event of a fire or smoke alarm.

ApplicationGeneric steel mullions can be used to sepa-rate vertically mounted galvanized steel fire dampers in wall openings larger

than the UL permitted multiple damper assembly size. Mullions can either be used vertically, horizontally or both to split up a vertical wall opening requiring use of a damper having a 11/2 hour fire resistance rating. Maximum mullion span is 120" (3048mm) plus expansion allowance when used either horizontally or vertically.

Sleeves are to be around each damper as-sembly. Mullions are not intended to be in the airstream, (i.e. exposed to flow) or to be a part of the ductwork.

Wall OpeningSteel mullions are intended for use in a concrete block or solid concrete wall. Hollow concrete blocks are to be filled with concrete (minimum 3500 psi) to permit proper mul-lion anchoring.

Wall thickness is to be 7" (178mm) minimum, 12" (305mm) maximum.

Support Mullions for Fire Dampers and Fire Smoke DampersFabrication and Installation Instructions

Manufacturer's RecommendationsAll moving parts of the damper must be inspected and cycled at intervals not greater than every six months and in accordance with the latest edition of NFPA 90A, 92A, local codes and the actuator manufacturer. In addition, fuse links shall be removed and inspected for corrosion. Dry lubricants are recommended. When UL is referred to in this document, it represents UL/ULC.

Mullion InstallationBefore the fire dampers are installed into the wall the anchored into the wall. The fire dampers may then be installed into the mullion assembly.

To correctly attach the mullions to the wall follow these steps:

1. Anchor wall mullion caps to wall using 1/4"-20 x 5/16" long flat head steel bolts and 3/8" (10mm) diameter by 1" (25mm) long concrete expansion anchors (Hilti). If steel lintels are present, use two 1" (25mm) long welds on each side of mullion caps. Note: End caps must be inserted into the ends of the mullions before they are anchored to the wall.

2. Anchor horizontal mullion caps to vertical mullion caps with 3/16" (5mm) diameter steel blind rivets in 12 places. Note: Mullion caps must be inserted into the ends of the mullions before they are anchored to the vertical mullions or wall.

Fire Damper InstallationGalvanized steel fire dampers must be UL classified for 11/2 hour fire resistance. They must be installed in galvanized steel sleeves and be retained by minimum 11/2" x 11/2" 1" (38mm x 38mm), 16 ga. retaining angles on each side of the wall. Retaining angles must overlap mullions or wall by 1" minimum. Fasten to sleeve using 1/4" 1" (6mm) dia. bolts, 3/16" (5mm) steel rivets, welding, or #10 sheet metal screws. All must be attached 6" 1" (152mm) on centers, 2" (51mm) maximum from corners. Do not fasten retaining angles to the wall or mullions. Mullions must be free to float. Total expansion clearance between sleeve and wall/mullion of 1/8" per foot of wall opening or mullion span should be allowed. Maximum clearance is 11/4" 1" (32mm).


Manufacturer's RecommendationsAll moving parts of the damper must be inspected and cycled at intervals not greater than every six months and in accordance with the latest edition of NFPA 90A, 92A, local codes and the actuator manufacturer. In addition, fuse links shall be removed and inspected for corrosion. Dry lubricants are recommended.

Only if required by the authority having jurisdiction

Application:The need to seal the damper in the penetration is not required by Underwriters Laboratories.PRICE dampers have been tested and approved to be mounted without the use of sealants around the perimeter space between the damper and the penetration. In certain cases, local codes request that this space be sealed to try and keep the integrity of the smoke barrier. These instructions have been produced to give direction where to apply caulk, if required by local codes. Suggested brands of caulk to use are Dow Corning 999, Dow Corning Silastic 732, Nuflex 302 and GE RTV 108 Sealant. Read and follow the sealant manu-facturer’s directions. Apply a continuous bead of caulk in the areas shown below. Do Not Apply sealant within the required expansion gap between the damper and the fire rated wall or floor. Allow the sealant to set up and become tack-free before operating the damper. See PRICE’s standard installation instructions for the basic installation of the damper. These instructions are for use following damper installation. Permission from the local codes inspector should be acquired before use of these instructions, to insure conformity with the local codes.

Manufacturer’s RecommendationsAll moving parts of the damper must be inspected and cycled at intervals not greater than every six months and in accordance with the latest edition of NFPA 90A, 92A, local codes and the actuator manufacturer. In addition, fuse links shall be removed and inspected for corrosion. Dry lubricants are recommended.

Procedure:1. Follow PRICE’s standard/general installation instructions for proper installation of the damper in the wall / floor.2. Clean all areas where the sealant is going to be applied. Remove dirt, oil, grease, or moisture from surface to be sealed. Allow to dry

thoroughly.3. Using G.E. RTV 108, Dow Corning Silastic 732 RTV, Nuflex 302 or Dow Corning 999 Silicone Caulk, apply a continuous bead around

the outside perimeter of the retaining angle, sealing them to the fire wall/floor (6). Do not apply caulk between angle and wall/floor. Also apply a continuous bead between the retaining angle and the damper sleeve(7). Be sure to seal the joints/corners of the retain-ing angles.

4. Be sure not to apply or get sealant within the required expansion gap between the sleeve and the fire wall/floor penetration. This gap is necessary for thermal expansion in the event of a fire.

5. After sealant is applied and before it sets-up, press the surface of the sealant in place to dispel any air. Do not operate the damper until the sealant has become tack-free.

Prior to today’s advancements in smoke control techniques, fan systems were re-quired to shut down during fire conditions and fire dampers were closed by heat. Air pressures were not utilized for the control and containment of smoke. In recent years, the requirement that systems completely shut down and fire dampers close and re-main closed during fire conditions has been questioned. With the current engineered smoke control systems simple closure of a fire damper at a specific temperature is no longer the absolute requirement. Combina-

FSD DAMPER DTO/R OPERATIONSwitch is in Normal (Open) Position damper motor is energized until thermostat senses temperature above initial closure rating. Above temperature closure rating, the damper motor is de-energized and damper closes.

Switch may then be moved to the Override Position and the damper will reopen and remain open until maximum operating tem-perature is reached. Once this temperature has been reached the damper motor is de-energized and the damper closes.

tion fire/smoke dampers may need to oper-ate at temperatures above and beyond their initial closure rating. PRICE’s DTO/R option provides the capability to override rated damper closure from a secure remote loca-tion (such as a fire fighter’s smoke control station). Upon sensing temperature above the initial rating (usually 165°F or 212°F) the damper will close but it may be reopened at the command of a remotely located control to permit utilization of the HVAC/Engineered Smoke Control System, but only until such time as the fire conditions exceed the maxi-

mum design limit. The DTO/R options also permits a combination fire/smoke damper to be reopened after a fire emergency has been controlled providing the temperatures at the damper have cooled down below the maximum design limit. Please note that the DTO/R option is recommended only for use in systems utilizing an Engineered Smoke Control design.

The DTO/R option is available on all PRICE Model FSD Combination Fire/Smoke Dampers.

In today’s world of many variables and controlled cost, PRICE offers several options to meet the needs of the industry. In many cases, the need to check for damper operation in the event a fire occurs is very hard to do, especially with the system running in a real time case. PRICE offers two options that allow for the fusible link to be removed and the operation of the damper checked, as in the event of a fire. Just merely turning the power off to the actuator may not tell you if the damper will close if the total HVAC system is shut down. It is also very difficult to melt the link while the system is running. Many times the system designer would like a systematic control closure of the damper to prevent ductwork implosion. PRICE offers the options PFV and EFL to meet these needs.

The PFV option has several features that make it a good choice on your job. First it does not require electric power to be at the damper’s location. An E-P switch is not required on a pneumatically actuated damper which has this option. When the link melts, the pneumatic power does not have to be shut off for the damper to close. The PFV costs less and has fewer parts to maintain than an E-P switch. Another feature is that the link can be easily removed and the damper inspected for operation under airflow conditions. By using the PFV over conventional fuse links, the HVAC system can be systematically control closed to prevent any duct implosion problems. Fusible links are available at 165°F and 212°F temperatures.

The EFL option has several features that make it a good choice as an option on your job. The fusible link can easily be removed from it’s holder, thus causing the damper to close for inspection while the HVAC continues to run. In many cases the EFL package can be easily removed from the outside of the duct and the link removed. By using the EFL over conventional fuse links, the HVAC system can be systematically control closed to prevent any duct implosion problems. Fusible links are available at 165°F and 212°F.

The InnovairFlex D4120A 4-wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of –4°F to 158°F, and a humidity range of 0 to 95 percent (non-condensing). A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. An improved cover design isolates the sensor head from the low-flow feature for simple maintenance.

The InnovairFlex housing provides ample wiring space, a ¾-inch conduit knockout, and built-in short circuit protection to prevent damage to sensitive components during installation. High contrast terminal designations make wiring easy. With its 2:1 sensor-to-power capability, the power board of the D4120A may be used to monitor a second sensor ,D4SA, simultaneously (i.e., supply and return side). As many as 50 InnovairFlex detectors can be interconnected. When one unit senses smoke, all interconnected detectors will switch their relays; only the detector sensing smoke will go into alarm, thus pinpointing the fire source.

An easy-access Test/Reset button makes it possible to test the unit with the cover on. Three DIP switches can be used to configure field selectable settings: cover tamper delay, number of sensors to be controlled, and shut down on trouble option. Each power board has two LEDs that can be used to indicate the status of connected sensors, and a quick reference imprinted on the cover explains the LED status indications (Standby, Maintenance, Trouble, and Alarm). The InnovairFlex duct smoke detector can be customized to meet local codes and specifications without additional wiring. The new InnovairFlex product line is compatible with all previous Innovair models, including remote test accessories.

WARNING: Duct smoke detectors are NOT a substitute for open area smoke detectors; NOT a substitute for early warning detection; NOT a replacement for a building’s regular fire detection system. Refer to NFPA 72 and 90A and CAN/ULC S524 for additional information.APPROVED

NOTES:1. Fasten the base plate to the duct or sleeve with two sheet metal screws through the holes. Align the switch strike so it is centered on the drive shaft.

2. Position the switch strike so that it actuates the microswitch MS-1 when the damper blades are open and the microswitch MS-2 when the blades are closed. When positioned secure to the drive shaft.

3. Factory furnished lead wires extend from the MLS-300 enclosure. Field connections are to be made to the leads and enclosed in a proper conduit.

4. If the output signals are reversed to that desired, reverse the �eld connections. Note that the wiring shown is for the indicator-switch being mounted on the left side of the damper if it is mounted directly to the damper axle, or on the right side of the damper if it is mounted to a jackshaft. If the indicator switch is mounted opposite of these locations, the wire connections should be reversed.

The MSD Switch Package provides the ability to remotely indicate the damper blade position, for direct mounting on damper driveshafts or jackshafts. It incorporates two integrally mounted microswitches for positive status indications. Electrical interface with a remote control on/o� fan station is also possible with the MSD package. The MSD option is available on PRICE model FSD combination �re/smoke dampers, model SSD smoke dampers, and FDD-MB multi-blade �re dampers.
