ORANGE COUNTY 230923-13 <br /> <br />Emergency Management Warehouse Building Dehumidification Extension of Existing Direct Digital <br /> Control System for HVAC <br /> <br />All cables shall be terminated using appropriate termination equipment. 1 <br /> 2 <br />Fiber Termination Panels: Provide a rack mountable, modular cabinet capable of terminating 3 <br />up to 24 type ST multimode fiber cables. Panels shall be as manufactured by Ortronics, Amp, 4 <br />Siecor, or Superior. 5 <br /> 6 <br />Fiber Optic Testing 7 <br /> 8 <br />Upon completion of the passive optical cable system, the system must be tested to 9 <br />ensure compliance with the design and link loss specifications. The tests include: 10 <br /> 11 <br />Power Meter Tests: For building risers, power meter tests are required. 12 <br /> 13 <br />End-to-End Attenuation Testing: Tests shall be completed on each fiber 14 <br />span at both operational wavelengths: 15 <br /> 16 <br />850/1310 nm multimode 17 <br /> 18 <br />1550 nm single mode 19 <br /> 20 <br />Testing in one direction is required. Link attenuation does not include any active 21 <br />devices or passive devices other than cable, connectors and splices (e.g., link 22 <br />attenuation does not include such devices as optical bypass switches, couplers, 23 <br />repeaters, or optical amplifiers. Test results should be retained for inclusion into the 24 <br />documentation package. 25 <br /> 26 <br />Connector loss readings of each completed connector should be recorded using an 27 <br />OTDR at 850 and 1310 nm in one direction. 28 <br /> 29 <br />Optical time domain reflectometer (OTDR) signature traces of each terminated fiber 30 <br />should be recorded at 850 nm and 1310 nm for fiber continuity purposes. OTDR 31 <br />testing is mandatory for runs longer than 2 km. 32 <br /> 33 <br />Final report shall be compiled which records system configuration, fiber labels, cable 34 <br />routes and “as built” details. Loss measurements with calibrated light source and 35 <br />power meter shall be included. OTDR traces shall also be included when requested 36 <br />in advance. 37 <br /> 38 <br />Pneumatic Tubing: Metallic tubing is required throughout. Except for short (24” max) flexible tubing final 39 <br />connections to pneumatic operators. 40 <br /> 41 <br />Exception: Non-metallic tubing may be utilized when operating at 45 psig or less and not more than 125 42 <br />degrees F. Except for short apparatus connections (not exceeding 24” in length), non-metallic tubing in 43 <br />mechanical rooms and other exposed locations shall be protected from mechanical damage by 44 <br />installation in raceway. Provide protective grommet where tubing exits raceway. 45 <br /> 46 <br />Smoke detectors and/or fan shutdown relays initiated by a fire alarm system shall be integrated into the control 47 <br />system and sequence of operation as indicated and/or required. 48 <br /> 49 <br /> 50 <br />FIELD QUALITY CONTROL 51 <br /> 52 <br />Perform the following field tests and inspections and prepare test reports after completion of DDC system 53 <br />installation: 54 <br /> 55 <br />After electrical circuitry has been energized, start units to confirm proper unit operation. Remove and 56 <br />replace malfunctioning units and retest. 57 <br /> 58 <br />Test and adjust controls and safeties. 59 <br /> 60 <br />DocuSign Envelope ID: 7668B866-6C26-485C-9A45-DAAB5D4BD951
