These should match the approved shop drawings. With out these, the BT and Fire Alarm Central Station Equipment cannot be programmed.

2. The project liaison will pass this information to the Fire Dept's Tech Services Office and Fire Alarm (F/A) section for ap proval, plus, advise the shop when the contactor is ready for the system programming. F/A section shall program the BT/Central Station and no tify the liaison when completed. This should only takes place right before the final inspection/testing date. Before the tranceiver wil l be programmed, the following items are required to be in the shops pos session; NFPA 72 Record of Completion, a test plan, a copy of all te st results (meggar, smoke sensitivity, resistance, intelligibility, and any device and panel), a set of working drawings, sized 12 X 18, t he box of spare parts, the Technician Interface Tool (laptop)-plus any special connecting cables or devices to interface with all systems to include VESDA, a copy of all data bases on a thumb drive, a nd 1 copy of all manuals (installation, programming, & operation)

3. Contractor shall perform the initial wattage ou tput test of the BT (this is part of the manufacturer's testing require ments). Contractor shall test of ALL fire alarm components, ensuring t he proper input and output responses.

4. The Engineering section will witness the above testing and concur that the contractor is ready for final verification test ing.

5. They will notify their liaison of the contracto r's proposed fire alarm system test date.

6. The liaison will coordinate this date with the F/A section (Mr. Chuck Lanning) and Eglin's Fire Department (Mr. Steve Car rico).

7. Project liaison will also inform the F/A sectio n that the BT is ready to be programmed with the information provided in s tep #1. (The contractor shall verify the operation of the F/A sy stem, BT, and Central Station, ensuring all sent and received inf ormation matches what was provided for approval in step #2).

8. The contractor will disconnect the commercial power to the F/A system for the duration called for in the project s pecifications. This timeframe will coincide with the beginning of the f ire alarm final inspection/testing date and time. This disconnectio n will be properly labeled with lock out/tag out procedures.

9. On the agreed testing date/time the contractor will test the F/A system on battery power as called for in the project speci fications.

10. When power is switched back to commercial, the contractor will perform the wattage output test for the FD and F/A section to witness, place the transceiver back on line, and then proceed with the final F/A system inspection/testing. Base personnel will coor dinate with fire dispatch and ensure the signals are being properly received at dispatch and correctly identified on the FACP and BT during this portion of the test.

NOTE: The contractor should have tested or schedul ed the testing of the exit and emergency lights around this same timefram e if these have not already been accomplished.
