CONSTRUCTION STANDARD SPECIFICATION

SECTION 13943

FACILITIES CONTROL SYSTEM

PART 1 - GENERAL
1.01 Summary

A. Instrumentation and control systems required for
HVAC systems and Sandia National Laboratories Facilities Control System
(FCS).

B. Remote control units, called Modular Building Controllers
(MBCs), located in individual buildings provide local monitoring and
control functions.  Each MBC communicates with an existing Facilities
Control System (FCS) Host Computer in Building 887 for remote monitoring
and control purposes.

C. SNL uses a Siemens Building Technologies, Landis
Division System 600 as its existing FCS System.  All FCS control
FIDs (Field Interface Devices) shall be System 600 products.

1.02 Submittals

A. Provide submittals in accordance with Section 01330, "Submittal Procedures.

B. Provide catalog and calibration data and procedures for all sensors,
switches, and controllers as part of submittals.

C. Provide control diagrams in the form of shop drawings
for each system or sub-system. Use the control diagrams included in
the contract drawings for this purpose. Each diagram shall be altered
to show all proposed controls and controlled devices, together with
name, catalog number, set point, and action of each controlled device.

D. Furnish reproducible copies of all contract drawings
for use in preparing there shop drawings.

E. Point verification forms shall be submitted for
all points that will be installed as part of the FCS.  These forms
shall be based on the point verification tests (PVTs) defined in Part
3 of this specification.  Once approved, these forms shall be used
during the startup verification phase of this work.

F. Detailed functional performance tests (FPTs) that
test all aspects of the sequence of operation. These aspects include
the testing of safeties, PID loops, emergency switch over routines,
alarm enunciation, temperature control, air volume control, pressurization
controls, flow control, fume hood control, graphics, etc. The test procedures
shall be comprehensive step-by-step procedures that can be repeated
by different individuals with the same expected outcome.  Equipment
to be tested shall include the supply and exhaust Air Handler Systems,
Hot Water System, Chilled Water System, Variable Volume Terminal Units,
and Fan Coil Unit controllers.

1.03 Quality Assurance

A. The contractor shall furnish, install, adjust,
calibrate, and make ready for use all required devices as stated in
the controls equipment schedule, on the drawings, wiring, instrument
air piping, and accessories required for a complete and totally functioning
HVAC control system. SNL shall only furnish the MBC cabinet, Controller
Modules, Power Supplies and I/O modules to the contractor.

B. The contractor shall provide all power, FCS, and
interlock wiring as required by the drawings and specification. 
This work includes all trenching, coring, etc. necessary to support
installation of the wiring systems.

C. Unless otherwise specified Sandia National Laboratories
(SNL) will provide the PPCL programming, code and graphics.  SNL
will provide, load, and checkout the PPCL and point database and perform
controls system functional test.

D. The contractor will perform all start-up, database,
and programming for the Terminal Equipment Controllers (TECs) using
contractor supplied equipment. The programming shall be completed in
accordance with FCS department established standards.

PART 2 - PRODUCTS

General

All control devices and products shall be selected
in accordance with the equipment schedule on the contract drawings.
Installation of the components shall be in accordance with Part 3 of
the Section. If a component is required to meet the requirements shown
on the drawings and is not specified, the Supplier shall select and
submit on components that meets all design requirements indicated on
the drawings, stated in the sequence of operation, and elsewhere in
the Contract documents. The quality of the submitted product shall be
commensurate with other products.

2.02 Wiring

A. All wiring shall comply with this specifications
and SNL Standard drawing MI5001STD.

B. FCS Class II wiring

1. Field wiring for each analog sensor shall be two
conductor 20 AWG twisted, shielded stranded with white sheath.

2. Field wiring for each digital input device shall
be two conductor 20 AWG twisted, shielded stranded with blue sheath.

3. Field wiring for each digital output device shall
be #14 type THWN.  Wiring shall be black.

4. Power wiring for end-controlled devices shall be
18 AWG cable with white sheath.

5. All wiring shall be installed in electrical-metallic
tubing (EMT) with watertight compression-type thread less fittings or
rigid galvanized steel conduit (RC) or Intermediate Metal Conduit (IMC).

6. All buried conduit shall be installed in accordance
with the Division 2 Exterior Site Construction sections of these specifications.

C. FCS Class I wiring

1. All materials required for installation of Class
I circuits or circuits operating at greater than 48 VAC or VDC shall
