SHEET F-100: FIRE ALARM AND MASS NOTIFICATION GENERAL NOTES

1. Modify the existing Fire Alarm and Mass Notification system as indicated on the contract documents, as evidently intended and in accordance with NFPA 70, NFPA 72, UFC 3-600-01 with change 6, and Tinker AFB Fire Protection Standards. The drawings are diagrammatic in nature and indicate general arrangements of systems and work, but do not include all interconnections between other systems. Provide conduit, back boxes, raceway and wiring as required to accomplish the functions intended and required by code.

2. Coordinate work with that of other trades so as to avoid conflicts. Resolve conflicts prior to rough-in. Failure to provide such coordination prior to work being installed shall not be cause for additional compensation to the contractor, and may result in rejection of the work.

9. Not used

14. Not used

SHEET F-100: SPRINKLER SYSTEM GENERAL NOTES:

16. Modified System. Construction and (Shop) Drawings must be prepared by an individual that has obtained National Institute for Certification in Engineering Technologies, Fire Alarm Systems, Level III Certification, at a minimum. the QFPE must review the shop drawings, and materials submittals. The shop drawings must bear the review stamp of the QFPE prior to submitting the fire sprinkler shop drawings to the government.

17. Submit Shop Drawings and product data to the government for review, in a manner as required per NFPA 13 and UFC 3-600-01. Submit equipment data sheets for a complete installation of the fire sprinkler system. Approved shop drawings, testing plans, and data sheets are required prior to commencement of work. The fire sprinkler system submittal shall be a complete package, partial submittal will not be accepted.

SHEET F-102: FIRE ALARM AND SPRINKLER COMPOSITE PLAN GENERAL NOTES

1. This sheet identifies the conveyor location requiring re-routing of the life safety systems currently installed on the conveyor platform. All fire alarm, mass notification, and fire sprinkler systems are to be uninstalled from the conveyor and reinstalled with supports connecting to the roof deck steel. New signs are to be installed only with no operational wiring or EMT. Existing signs shall remain in their current location in their current status.

2. Before removing any electrical conduit, conductors, or devices, ensure and verify that the circuit is properly de-energized.

3. The intent is to disconnect the fire alarm circuits and fire sprinkler drops to demolish the overhead conveyor. Re-route systems cabling and drops to the bottom of roof truss steel above the conveyor platform.

4. Provide red EMT of ¾” inch minimum with compression fittings for all new fire alarm raceway. Existing red EMT may be reused if it is like new condition. All new EMT shall be factory painted red and ¾” inch minimum.

5. New circuit and piping route shall be along the lower roof truss steel supports above the current conveyor platform.

6. Fire sprinkler branch lines and supporting hangers may be uninstalled and reinstalled or demolished, as needed for code compliance.

7. Existing FCI-E3 network fire alarm located on the second level next to O-P aisle. The second level is open to the aisle, located at column O-94/95 on the second level.

8. Existing class A circuits may be converted to class B per the equipment manufacturer's instructions in accordance with NFPA 72. Do not abandon any fire alarm, mass notification circuits or raceway.

9. Perform a pre-test of the alarm and sprinkler systems impacted by the relocation of circuits prior to beginning work. Deficiencies identified during the pre-test will not be the responsibility of the contractor to correct if issue remains during the final acceptance test.

10. Perform an acceptance test for all affected alarm and sprinkler systems in accordance with NFPA 13 and 72, upon the completion of work. Contractor will correct deficiencies not identified on the pre-test.

11. Submittals are required. Accurate record drawings (as-builts) are required to be provided by the contractor as a close-out submittal.

12. Provide work in compliance with referenced codes and standards.
