METAL SUSPENSION SYSTEMS FOR LAY -IN
<br />PANEL CEILINGS
<br />1. 12 GA. (MIN.) HANGER WIRES MAY BE USED
<br />FOR UP TO AND INCLUDING 4'-0' X 4'-0' GRID
<br />SPACING ALONG MAIN RUNNERS. SPLICES
<br />WILL NOT BE PERMITTED IN ANY HANGER
<br />WIRES UNLESS SPECIFICALLY APPROVED BY
<br />DSA/SSS.
<br />2. PROVIDE 12 GA. HANGER WIRES AT THE ENDS
<br />OF ALL MAIN AND CROSS RUNNERS WITHIN 8"
<br />FROM THE SUPPORT OR WITHIN 1 /4" OF THE
<br />LENGTH OF THE END TEE, WHICHEVER IS LEAST,
<br />FOR THE PERIMETER OF THE CEILING AREA.
<br />3. PROVIDE TRAPEZE OR OTHER SUPPLEMENTARY
<br />SUPPORT MEMBER AT OBSTRUCTIONS TO MAIN
<br />HANGER SPACING. PROVIDE ADDITIONAL
<br />HANGERS, STRUTS OR BRACES AS REQUIRED
<br />AT ALL CEILING BREAKS, SOFFITS, OR
<br />DISCONTINUOUS AREAS. HANGER WIRES THAT
<br />ARE MORE THAN I IN 6 OUT OF PLUMB TO

<br />RUNNERS, ONE END OF MAIN AND CROSS
<br />RUNNER SHOULD BE FREE AND A MINIMUM OF
<br />I/2" CLEAR OF THE WALL.
<br />5. AT THE PERIMETER OF THE CEILING AREA
<br />WHERE MAIN OR CROSS RUNNERS ARE NOT
<br />CONNECTED TO THE ADJACENT WALL,
<br />PROVIDE INTERCONNECTION BETWEEN
<br />RUNNERS AT THE FREE END TO PREVENT
<br />LATERAL SPREADING. A METAL STRUT OR A 16
<br />GA. WIRE WITH POSITIVE MECHANICAL
<br />CONNECTION TO THE RUNNER MAY BE USED.
<br />WHERE THE PERPENDICULAR DISTANCE FROM
<br />THE WALL TO THE FIRST PARALLEL RUNNER IS
<br />17' OR LESS, THIS INTERLOCK IS NOT REQUIRED.
<br />6. PROVIDE SETS OF FOUR 12 GA. SPLAYED
<br />BRACING WIRES ORIENTED 900 FROM EACH

<br />PROVIDE BRACING WIRES AT LOCATIONS
<br />NOT MORE THAN 6'-0' FROM EACH PERIMETER
<br />WALL AND AT THE EDGE OF VERTICAL
<br />OFFSETS.
<br />THE SLOPE OF THESE WIRES SHOULD NOT
<br />EXCEED 450 FROM THE PLANE OF THE CEILING
<br />AND SHOULD BE TAUT WITHOUT CAUSING THE
<br />CEILING TO LIFT. SPLICES IN BRACING WIRES
<br />ARE NOT TO BE PERMITTED WITHOUT SPECIAL
<br />DSA/SSS APPROVAL.
<br />7. FASTEN HANGER WIRES WITH NOT LESS THAN 3
<br />TIGHT TURNS, FASTEN BRACING WIRES WITH 4
<br />TIGHT TURNS, MAKE ALL TIGHT TURNS WITHIN A
<br />DISTANCE OF 1 1 /2'. HANGER OR BRACING
<br />WIRE ANCHORS TO THE STRUCTURE SHOULD
<br />BE INSTALLED IN SUCH A MANNER THAT THE
<br />DIRECTION OF THE WIRE ALIGNS AS CLOSELY
<br />AS POSSIBLE WITH THE DIRECTION OF THE
<br />FORCES ACTING ON THE WIRE.
<br />NOTE: WIRE TURNS MADE BY MACHINE WHERE
<br />BOTH STRANDS HAVE BEEN DEFORMED OR
<br />BENT IN WRAPPING CAN WAIVE THE 1 1/2'
<br />REQUIREMENT, BUT THE NUMBER OF TURNS
<br />SHOULD BE MAINTAINED, AND BE AS TIGHT
<br />AS POSSIBLE.
<br />8. SEPARATE ALL CEILING HANGING AND
<br />BRACING WIRES AT LEAST 6 INCHES FROM ALL
<br />UNBRACED DUCTS, PIPES, CONDUIT, ETC.

<br />DISTRIBUTION, AND OTHER SERVICES
<br />NORMALLY FOUND IN A CEILING SPACE,
<br />SHALL BE INDEPENDENTLY SUPPORTED AND
<br />APPROPRIATELY BRACED TO ELIMINATE ANY
<br />LATERAL FORCE ON THE CEILING MEMBRANE
<br />OR BRACING ELEMENTS.
<br />9. WHEN DRILL -IN CONCRETE ANCHORS OR
<br />SHOT -IN ANCHORS ARE USED IN REINFORCED
<br />CONCRETE FOR HANGER WIRES, 1 OUT OF 10
<br />MUST BE FIELD TESTED FOR 200 LBS. OF
<br />TENSION. WHEN DRILLED -IN CONCRETE
<br />ANCHORS ARE USED FOR BRACING WIRES, I
<br />OUT OF 2 MUST BE FIELD TESTED FOR 440 LBS.
<br />OF TENSION. SHOT -IN ANCHORS IN
<br />CONCRETE ARE NOT PERMITTED FOR
<br />BRACING WIRES. IF ANY SHOT -IN OR
<br />DRILLED -IN ANCHOR FAILS, ALL ADJACENT
<br />ANCHORS MUST BE TESTED. DRILLED -IN OR
<br />SHOT -IN ANCHORS MUST BE TESTED.
<br />DRILLED -IN OR SHOT -IN ANCHORS REQUIRE
<br />SPECIAL DSA/SSS APPROVAL WHEN USED IN
<br />PRE -STRESSED CONCRETE.
<br />10. ATTACH ALL LIGHT FIXTURES TO THE CEILING
<br />GRID RUNNERS TO RESIST A HORIZONTAL

<br />THE WEIGHT OF THE FIXTURE. ALL FIXTURES
<br />REGARDLESS OF WEIGHT OR SIZE SHALL HAVE
<br />INTERLOCKING CEILING GRID RUNNER(S) ON
<br />ALL 4 SIDES OF THE FIXTURE.
<br />11. CEILING MOUNTED AIR TERMINALS OR
<br />SERVICES SHALL BE POSITIVELY ATTACHED TO
<br />THE CEILING SUSPENSION MAIN RUNNERS OR
<br />TO CROSS RUNNERS WITH THE SAME
<br />CARRYING CAPACITY AS THE MAIN RUNNER.
<br />AIR TERMINALS WITH A NOMINAL DIMENSION
<br />OF 24" OR LESS SHALL BE POSITIVELY
<br />ATTACHED TO THE CEILING GRID RUNNERS)
<br />ON AT LEAST TWO OPPOSING SIDES WITH ONE
<br />SELF -TAPPING TEK SCREW ON EACH SIDE. EACH
