STEEL ACOUSTICAL DOOR ASSEMBLIES 12SOUND 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 13D. 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 14C. 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 15G. 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 16H. 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 175. 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 18E. 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 196. 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.
