The Temperature Control system shall be a combination electronic Direct Digital Control (DDC) with pneumatic actuation. All necessary control panels, relays, switches, system software, valves, valve actuators, sensing devices, and damper operators shall be provided, installed, and commissioned to insure proper operation of the temperature control system as detailed in the sequence of operation, whether noted on the plans and specifications or not. The systems shall be properly connected, piped and wired in a manner conforming to the laws, ordinances and codes now in force in the Commonwealth of Kentucky.

F. The facility management system (FMS) specified for this project shall seamlessly interface to the existing Johnson Controls Metasys, facility management system. If the existing facility management system cannot meet the requirements specified in this section, the controls manufacturer shall provide all hardware, software, installation, control wiring, engineering and programming etc. to upgrade the existing facility management system to meet the requirements of this section. All new and existing manufacturers specific hardware points, software points, DDC controllers, Network Controllers, Workstations and software system objects shall be monitored, controllable and accessible as described in this section from either the Johnson Controls ADX Operator Workstation, located in the Peterson Service Building Delta Room. Providing additional computer workstations, Internet IP Protocol Access, Java script programming, windowing between different or loading separate facility management system software on one of the above Workstations for interface to the new and existing facility management system is not acceptable.

G. The facility management system shall interface to the existing Campus FDDI segmented WAN network via 10BASET communication hub(s). With respect to all new and existing DDC controllers, Network Controllers and workstations communicating over the campus WAN network, all control points and software features described in this section shall be operable from one of the existing operator terminals located in the Peterson Service building. Modem communication is not acceptable for this application. There shall only be one physical connection to the campus FDDI WAN network.

H. All controller programs shall have the ability to download and upload over the campus Ethernet network.

I. UK Communications department shall provide all required HUB’s routers and switches required to interface to the campus WAN network. The cost for this work shall be included by the controls manufacturer. Obtain pricing from the UK Campus Communication Department prior to bid.

J. EMS Connections to Third Party Equipment: Provide these connections and points as indicated in the Sequence of Operation and/or the I/O Summary Sheets. Third Party equipment includes but is not limited to, computer room air conditioning units, condensate pumps, transfer switches, HVAC variable speed pumping systems, sump pumps, fire alarm systems, lighting systems, etc.

K. Coordinate with third party equipment suppliers to determine equipment devices, such as, printed circuit boards, contacts, etc. required for EMS connections. Provide any necessary connection devices not provided by the third party equipment suppliers.

L. Electrical power wiring and interlock wiring for all controls, signal devices, alarms, etc., shall be in accordance with diagrams and instructions from the supplier of the systems. All power and control wiring, conduit and wiring connections required for the complete installation, including wiring to smoke dampers and combination fire/smoke dampers and their motors, shall be provided by this Contractor in accordance Electrical 16 specification requirements.

M. Refer to 15525d01 drawing standard.

GENERAL

Energy Computer: Stand-alone Microprocessor Based System

Setup Memory: Non volatile totalized energy and setup information memory such that loss of power does not result in loss of this information. Also, system must automatically resume, without human intervention, pre-power failure operation when normal power is restored.

ENCLOSURE

All system components to be enclosed in a NEMA 4 enclosure and all displays and alarms to be visible with enclosure shut.

POWER 115 V.A.C., 60 HZ.

ENVIRONMENT Ambient Temperature: 0 120 degree F

LIGHTNING PROTECTION (To be provided by system installer)

All electric/electronic equipment supplied must be internally or externally lightning/transient surge voltage protected on all external power feeder and input/output connections which are subject to surge voltage (lightning) transients. Provide high speed clamping elements which meet IEEE. STD. 472 (SWC) on all digital or analog data channels.

NOTE: If this spec. applies to systems which are to be installed in underground pits, the 115 V.A.C. supply voltage and all remote input/outputs must be lightning protected.

ACCURACY
