SOUND RETARDANT DOOR
HARDWARE INFORMATION BULLETIN

Through our experience in manufacturing sound retardant doors, we have found that problems occur
when certain hardware is used that will compromise the effectiveness of the sound door assembly.
On the following pages, we have tried to address some of the more common situations, and offer
some alternative solutions which will preserve, or enhance, the performance of the assemblies.



1. 	HINGES
    Weight of the doors will vary, depending
    on size, and STC rating. Refer to the door
    schedule sheets of shop drawings for weight
    of door. Also see General Information page,
    under Hinge Location, or, contact Krieger’s
    engineering department. In any case, we
    always recommend the use of heavy-duty
    ball-bearing hinges.



2.	CLOSERS
  A.    Parallel arm closers: Mount the arm
		      bracket to “Z” bracket furnished by Krieger,
		      or use a top jamb mounted closer. Closer
		      arm shoe must NEVER be mounted
		      directly to the seal cover.

  B.    Rixon floor closer: The arm which must
		      mount in the bottom of the door precludes
		      the use of a mortised door bottom. We do
		      not recommend using this hardware item
		      on acoustical doors.

  C.    Concealed overhead closer: This
		      mounts in the head of frame and would not
		      permit a continuous perimeter seal, resulting
		      in a sound leak. We cannot certify an STC
		      rating with this setup.




                                                                     Acoustical Hardware Bulletin 13
D.    CLOSERS RECOMMENDED FOR USE
		      WITH CAM LIFT HINGE ASSEMBLIES:
		      The cam lift hinges will not, by themselves,
		      close and/or latch, the door. The door
		      bottom seal is coming down onto the sill
		      the last ten degrees of swing, so there is
		      some friction, depending on how tightly
		      the seal is adjusted. Also the seal on the
		      jamb, either compression or magnetic,
		      will affect how easily the door will latch,
		      depending on how evenly. It is adjusted
		      around the entire perimeter. A door closer
		      is required. Also, any U. L. rated doors
		      would need a closer if they are to bear
		      the label.

		You must choose a closer that allows for 3/8" vertical movement. After checking with several closer
		 manufacturers, we offer the following recommendations:
			 •         LCN 4010, 4020, 4041 Super Smoothie
			 •         Dorma series 640, 540, 7600, 7800, and TS83
			 •         Corbin/Russwin DC2000, DC3000, DC4000
			 •         Norton 7500, 8500 series
			 •         Sargent 250, 251, 350, 351, 1230, 1231, 1250, and 1251
				          (Please note that no documentation has yet been received from Norton or C/R validating this recommendation)

		      Closers not recommended: LCN: 4110, 4041 Cush-N-Stop, 4040 EDA (Extra Duty Arm),
		      and any others with a large bolted knuckle at the elbow that will not allow 3/8" vertical movement.
		      Slide track type closer and overhead stops will not work.



3.	LOCKS
  A.    Cylindrical locks like the Schlage
		      “D” Series: Our perimeter seals are 1-1/8"
		      high. Latest oversize roses for lever trim
		      (with spring assembly) will overlap them,
		      at 2-3/4" backset. Or, if a knob is used,
		      there is very little grasping clearance
		      with this backset. We therefore strongly
		      recommend that you always use a 3-3/4"
		      backset, for either levers OR knobs.

  B.    Mortise locks are available only with
		      a 2 3/4" backset. For this reason, lever
		      handles should be used instead of
		      knobs to insure proper clearances.




                                                                                  Acoustical Hardware Bulletin 14
C.   Unit locks like the Corbin 300 are not
		     recommended, under any circumstances:
		     These locks require that the entire edge of
		     the door be notched out. The escutcheon
		     is too close to the edge of the door and
		     hits the perimeter seal preventing contact
		     between the door and the seal. We cannot
		     certify an acoustical rating with this lock.

  D.   The Simplex Unican 1000 digital
		     control lock is very sensitive, we recommend
		     specifying a “roller strike” when using this
		     lock in conjunction with (NC-6 magnetic)
		     seals. We would also suggest substituting
		     a heavy duty Schlage Door “D” series latch
		     bolt with a 3 3/4” backset. Also see below.



  E. As an alternate to the Simplex item, we
		 suggest considering the use of the Yale
		 2100 series Touchcode or Alarm lock
		Trilogy DL 2500 series digital cylindrical
		 lock with a 3 3/4" backset. These units
		 are battery operated.
		     Yale Cylindrical Touchcode 2150 / 2160 or
		     Alarm lock Trilogy DL 2500 Series.




  F.   Locks For Use With 3" Thick Doors:
		     The combination of dual seals, 2-1/4" in
		     height, and the increased door thickness
		     somewhat limits the selection of latching
		     hardware that is compatible with this
		     design. We recommend that you use
		     a cylindrical lock with 5" backset; or
		     please consult with Krieger’s engineering
		     department before making final selection.




                                                      Acoustical Hardware Bulletin 15
G.    Acoustical Doors & Electric Strikes
		      We suggest the customer use an electric lock in lieu of an electric strike. This will permit seals
		      to be adjusted properly, which will substantially reduce the risk of compromising the sound rating
		      of the opening.
		      Most electric strikes are too sensitive and bind up when used with “compression” type seals;
		      for that reason we recommend they not be used together.

		      Compression seals create pressure between the lock latch bolt, and the gate of electric strike
		      which will not allow the gate to activate and retract. If electric strikes must be used, magnetic
		      seals should be utilized.

		      Electric locks require low voltage power be routed through the door. At conventionally hinged
		      (level swing) openings this transfer is best done with an electrified hinge. At doors with cam-lift
		      hinges, a seperate power transfer device is required, such as the Adams-Rite 4611, the AMD
		      ES105, or the new Von Duprin EPT2.

		You should contact our engineering team to review the model numbers of any electrified hardware
		 being considered, to ensure compatibility with perimeter sound seals, and that the assembly will
		 operate properly, while also meeting the noise reduction requirements.




                                                                           Acoustical Hardware Bulletin 16
H.    Electric Strikes at Pairs:
		      Some electric strikes for pairs of doors,
		      (example: Von Duprin 3071, 3081, and
		      6221) require a cutout through the door.
		      We do not recommend strikes of this type
		      be used because of the hole through the
		      door and the fact they will not work with
		      the overlapping astragals. The Von Duprin
		      3091, 3092, and 6223 would be a better
		      choice for sound rated openings.




4.   FLUSH BOLTS
  A. Flush bolts at inactive leaf of pairs: The bottom rod needs to be offset
		 (approximately 1/2," easily done in field by installer), so as to not interfere
		 with the mortised or cam lift door bottom.

  B.    Automatic Flush Bolts: We do not recommend the use of automatic
		      flush bolts on pairs of doors furnished with sound seals. When the doors
		      are closed, and compression gaskets on the frame and astragal are adjusted
		      to seal properly, the automatic flush bolts will not retract when the active leaf
		      is opened. This is because the seal causes the side of the bolt to be pressed
		      tightly against the side of the strike cutout. While the bolt may be retracted by
		      pulling the door tightly against the seals, when the door is closed again the bolt will not
		      automatically enter the strike, since it requires a loose clearance in order to function.

		      When permitted by local authority, a U.L. Listed manual flush bolt should be used in lieu of the
		      automatic type, or (Glynn Johnson FB50, Door Control 845 constant self latching flush bolts).
		      Another alternative would be to use optional KSP mullion with a positive latch in each door.
		      Please contact Krieger’s engineering department for additional information on this condition.




                                                                           Acoustical Hardware Bulletin 17
5.   PANIC DEVICES
  A.   Concealed vertical rod type,
		     example: Von Duprin 8847 or 9947; these
		     devices require a large open area, full height
		     inside the door, which unacceptably reduces
		     the effective area of the sound retardant core,
		     as well as precluding the use of a mortised
		     automatic, or cam-lift, door bottom. For these
		     reasons, we do not recommend their use
		     where noise reduction is critical. We cannot
		     certify an STC rating with this configuration.




  B.   Surface vertical rod type,
		     example: Von Duprin 8827 or 9927; the
		     surface mounted roller latch should be
		     mounted on a “Zee” bracket (furnished
		     by Krieger) at the head, NEVER on the
		     sound seal itself! Also, any screws occurring
		     within the bottom 3” of the door must be
		     cut short and filed or they will prevent
		     theautomatic door bottom from
		     operating properly.




  C.   Rim type (single doors only), example: Von Duprin 88 or 99; the surface mounted roller latch should
		     be mounted on a “Zee” bracket (furnished by Krieger). It cannot be used at pairs due to the use of
		     overlapping astragals on the “push” side of the door. If rim devices must be used at pairs, a Krieger
		     mullion (not VD 8954 type) would be required. A far better answer would be to use two mortise
		     devices (VD 9975); these also need a mullion.



  D.   Fire rated surface vertical rod,
		     example: Von Duprin 8827-F; this uses
		     a soffit latch assembly in the head of
		     frame. This cannot be mortised into
		     the perimeter seal! If used, it can be
		     mortised into a metal box mounted
		     below the seal, attached to the frame
		     with a special zee bracket furnished
		     by Krieger.




                                                                       Acoustical Hardware Bulletin 18
E.	RECOMMENDED EXIT DEVICES FOR PAIRS WITHOUT MULLIONS:

CORRECT:                                                 DO NOT USE!
If both leaves of a pair of doors with panic devices     If surface vertical rod exit devices are specified
are “active”, a coordinator will be required because     on both doors, then the inactive leaf cannot be
of the overlapping astragal(s). (A Must for acoustical   opened until the active leaf is opened, since both
performance) in this case we recommend using a           leaves are latched top and bottom and have
mortise lock exit device on the active leaf, with a      overlapping astragal(s). We cannot certify an
surface vertical rod device on the inactive leaf.        STC rating without astragal(s).
This allows either leaf to be active.




                                                                        Acoustical Hardware Bulletin 19
6.	THRESHOLDS
   Acoustical doors must have a smooth surface for the door bottom seal to land on, slide across, and
   seal against when finally closed. This applies equally to a level-swing door with automatic bottom, or
   to a cam-lift door with fixed (adjustable) seal. When sound doors swing over carpet, a smooth surface
   saddle threshold, at least the same height as the carpet, preferably slightly higher, MUST be used. This
   is also essential to preventing a sound leak under door through the carpet. Thresholds are to be set in
   a good grade of acoustical sealant. The use of fluted and/or abrasive coated thresholds will cause
   premature wearing of the door bottom neoprene, and could cause the seal to pull out of its’ retainer
   and jam up under the door. All thresholds must be set so as to extend 1-1/2” minimum beyond the
   pull side of the door to provide a “landing” area for the door bottom (either type) as they start to descend.




                                                                            Acoustical Hardware Bulletin 20
