FASTENER SCHEDULE

NOTE:

1. METAL SECTIONS SHALL BE SECURED AT EACH END ON THE INSIDE EDGE UNDER THE JOINT COVER WITH TWO LARGE STAINLESS STEEL

NAILS THROUGH SLOTTED HOLES. 6-INCH WIDE JOINT COVERS SHOULD BE HOOKED OVER THE METAL AT THE UPPER AND LOWER ENDS. A BEAD OF SEALANT SHALL BE APPLIED UNDER THE JOINT COVER 1-INCH FORM THE END OF EACH METAL ROOF EDGE SECTION. ADD ONE #10 STAINLESS STEEL SHEET METAL SCREW WITH NEOPRENE WASHER AT THE CENTER OF EACH SECTION ON THE INSIDE EDGE, AND AT THE CENTER OF EACH JOINT COVER. THE SECTIONS OF METAL ROOF EDGE SHALL BE SEPARATED BY 3/4-INCH SO THAT THE SCREW

THROUGH THE JOINT COVER CLEARS THE METAL FASCIA.

GENERAL DRAWING NOTES:

1. THE DESIGN IS BASED ON HEARY BROS. LIGHTNING PROTECTION CO.,

INC. ANY APPROVED EQUIVALENT THAT MEETS THE SAME STANDARDS

WILL ALSO BE ACCEPTED.

2. THE LIGHTNING PROTECTION SYSTEM AS SHOWN ON DRAWING HAS

BEEN DESIGNED IN ACCORDANCE WITH UL96A & NFPA-780 LIGHTNING

PROTECTION SYSTEM STANDARDS.

3. CONDUCTORS SHALL MAINTAIN A HORIZONTAL OR DOWNWARD COURSE,

FREE FROM "U" OR "V" (DOWN AND UP) POCKETS.

4. NO BEND OF CONDUCTOR SHALL FORM AN ANGLE OF LESS THAN 90°

NOR SHALL HAVE A RADIUS OF BEND LESS THAN 8".

5. AIR TERMINALS SHALL BE SPACED EVERY 20'-0" MAXIMUM AROUND THE

ROOF PERIMETER AND/OR ALONG ROOF RIDGES. AIR TERMINALS SHALL

BE LOCATED WITHIN 2'-0" OF OUTSIDE CORNERS.

6. AIR TERMINALS SHALL BE SPACED EVERY 50'-0" MAXIMUM IN CENTER

ROOF AREAS.

7. ACTUAL JOBSITE CONDITIONS MAY REQUIRE SLIGHT ALTERATIONS IN

AIR TERMINAL, DOWN CONDUCTOR AND GROUND ROD LOCATIONS.

8. BARE COPPER MATERIALS SHALL NOT BE INSTALLED ON ALUMINUM OR

GALVALUM SURFACES, AND ALUMINUM MATERIALS SHALL NOT BE

INSTALLED ON COPPER SURFACES.

9. ALL LIGHTNING PROTECTION CONDUCTORS SHALL BE FASTENED EVERY

3'-0" MAX.

10. ALL BOLTS ON BOLT-PRESSURE CONNECTORS SHALL BE TORQUED AT

150 IN-LB.

11. ALL CONNECTIONS MUST BE USED WITH UL LISTED CABLE OF SAME

METAL TYPE.

12. SMALL METALLIC BODIES OF INDUCTANCE SITUATED WITHIN 6'-0" OF A

LIGHTNING CONDUCTOR OR ANOTHER BONDED METAL BODY SHALL BE

INTERCONNECTED TO THE LIGHTNING CONDUCTOR SYSTEM, UNLESS

INHERENTLY GROUNDED. (ROOF DRAINS, SMALL PLUMBING VENTS,

FLASHINGS, COUNTERFLASHINGS, ETC).

13. BOND ALL LARGE METAL BODIES TO THE MAIN LIGHTNING PROTECTION

CONDUCTOR. (I.E.; EXHAUST FANS, ROOF VENTS/FLUES, METAL

COOLING TOWERS, HVAC UNITS, LADDERS, RAILINGS, ANTENNAS,

SKYLIGHTS, METAL STACKS AND ANY OTHER LARGE METAL BODY

WHOSE HEIGHT EXCEEDS THAT OF THE AIR TERMINAL IN USE, UNLESS

PROTECTED BY HIGHER ROOF ELEVATIONS).

14. IDENTIFY ALL UNDERGROUND UTILITIES BEFORE INSTALLING GROUND

RODS TO AVOID DISRUPTIONS. CONNECTIONS TO GROUND RODS SHALL

BE MADE AT A POINT NOT LESS THAN 1'-0" BELOW FINISHED GRADE AND

2'-0" AWAY FROM FOUNDATION WALL.

15. BOND TO WATERLINES (DOMESTIC & FIRE).

16. A LIGHTNING ARRESTOR, PROTECTOR OR ANTENNA DISCHARGE UNIT

SHALL BE INSTALLED ON EACH ELECTRIC AND TELEPHONE SERVICE

AND RADIO AND TELEVISION ANTENNA LEAD-IN BY THE ELECTRICAL

CONTRACTOR, IN ACCORDANCE WITH NFPA-70.

17. TRANSIENT VOLTAGE SURGE SUPPRESSION (TVSS) OF SERVICES SHALL

BE PROVIDED BY THE ELECTRICAL CONTRACTOR. (I.E. COMPUTERS,

COPIERS, TELEPHONE, ETC.).

18. PROVIDE UL MASTER LABEL CERTIFICATION UPON COMPLETION OF

INSTALLATION.

19. SEE DETAILS ON SHEETS E301 - E304 FOR TYPICAL CONNECTION

DETAILS.

KEYED DRAWING NOTES:

DOWN CONDUCTOR TO GROUND ROD. DOWN CONDUCTORS SHALL NOT

EXCEED 100' (TYP.). CONFIRM DOWN CONDUCTOR LOCATIONS WITH THE

UNIVERSITY PROJECT MANAGER BEFORE INSTALLATION.
