ACM7 Seismic Clip
Description
The Donn ACM7 seismic clip is designed to provide the most robust hold in the most stringent
seismic design categories.
ACM7 Seismic Clip
Features and Benefits
– Meets or exceeds all national code requirements with 7/89 wall molding
– Offers an aesthetically attractive option to traditional 29 angle molding
– Fulfills requirements for IBC Seismic Design Categories C, D, E and F
– Provides evidence of compliance (and greatly exceed) ICC Evaluation Service, Inc. (ICC-ES) AC156 and
AC368 requirements
– Provides support on either side of the web and around the bulb of the tee
– Laboratory-tested to greatly exceed all structural and seismic requirements including tension, compression and
tee fallout
– Either wing can be snipped off to fit corners and other tight spaces
– The clip adjusts easily to accommodate tees that intersect the wall at an angle other than 90 degrees
– No special fasteners required
– Lifetime limited warranty
Applications
– All interior general use areas
– All main Donn suspension systems, DX®/DXL™, Fineline® (DXF), Fineline® 1/8 (DXFF), Centricitee™ (DXT),
CE (Controlled Environment), DXW, DXLA™, and ZXLA™ (Environmental), include the code-compliant
intermediate-duty and heavy-duty main tees for Seismic Design Categories C, D, E and F.

The Donn ACM7 seismic clip is designed to provide a more robust hold than traditional L-shaped seismic clips
by other manufacturers.
ACM7 Seismic Clip
The ACM7 clip features a saddle that fits securely over the tee bulb and fastens to the tee web. This clip also
provides two tow wings, which connect to the wall molding on each side of the tee with screws and friction-fit tabs.
Either wing can be snipped off to fit corners and other tight spaces. And, the clip adjusts easily to accommodate
tees that intersect the wall at an angle other than 90 degrees.
The ACM7 clip sustained tremendous forces in tension and compression testing, far greater than would be
experienced in a seismic event.

Failure Criteria
Tee fallout/ separation from clip.
Result
> 500 load (lbs.).
Test stopped at this load, with clip still attached to tee;
failure load will exceed this level.
Compression Test
Tee fallout/ separation from clip.
> 300 load (lbs.).
Test stopped at this load, with clip still attached to tee
maintaining 3/49 clearance from wall; failure load
will exceed this level.

Installation
Must be installed in compliance with
ASTM C636, CISCA, and standard
industry practices.
Limitations
The performance of Donn ACM7
seismic clip and systems is based on
the specific combination of superior
components, and design and installation methods shown. Components
from other manufacturers were
not evaluated, and their use or any
mixed use is not recommended.

AC156 Disclaimer
The current ICC-ES acceptance
criterion (AC) used for the testing
and evaluation of seismic clips is
AC156, Acceptance Criteria for
Seismic Qualification by Shake-Table
Testing of Nonstructural Components
and Systems. AC156 was not
specifically designed to provide
testing guidelines or pass/fail criteria
for acoustical suspension systems
in a seismic event. However, in the
absence of a specific AC for this
purpose, ICC-ES allowed AC156 to
act as the basis for all seismic testing
and evaluation for the acoustical
ceiling suspended ceilings industry.
demonstrate compliance with the
performance features of the codes.
The data and test results presented
provide technical evidence on which
a code official can base approval.
Code Compliance
Testing and evaluation performed
at the University at Buffalo (SUNY),
the Department of Civil, Structural
and Environmental Engineering—
Structural Engineering and
Earthquake Simulation Laboratory
(SEESL) qualify the performance
of these systems according to the
AC156—Seismic Qualification
Specification, and AC368—
Acceptance Criteria for Suspended
Ceiling Framing Systems. Several
alternative materials, designs and
methods of construction were
evaluated and tested. Results of
this investigation indicates that
these tested alternative designs
are at least the equivalent of that
prescribed in the code for quality,
strength, effectiveness, fire
resistance, durability and safety.
These alternative designs are at least
equivalent to the criteria set forth in
AC156 and AC368, and otherwise
