EMDBs, MDBs, ATS, Fire Alarm Control Panel, Security System Panel and FM200

System Panel on the other hand.

Practically, the building management system of this project consists of a Main BMScontroller room, located in the Control Room of QQ01 Building. The BMS controlroom consists of both the BMS workstation and the Network Automation Engine(NAE) enclosure:

The BMS workstation, consisting of a desktop computer, can give access to the dataof each of the Building Levels and Parking Levels. The NAE enclosure, on the otherhand, consists of three (3) Network Automated Engines that manage facilities usinginformation and Internet technology. The NAE uses the BACNet network to monitor

and supervise Heating, Ventilating, and Air Conditioning (HVAC) equipment, lighting,and third party systems. In addition the NAE devices provide monitoring and control,alarm and event management, data exchange, trending, energy management,scheduling, and data storage.

Each NAE is connected through the BACNet (BACNet Network) cable to all theBACNet controllers which are spread across the building levels in panels that werefer to as the Data Gathering Panels (DGP).These BACNet controllers in turn areconnected to the different sensors and volt free contacts that consists the core of theinformation the BMS system is monitoring and controlling.

The purpose of this document is to break down and detail the whole procedure oftesting and commissioning of the Building Management System of The Pearl -Qanat Quartier (Apartment) J46.

Consequently, the BMS team progressively inspects all BMS device installation,cable pulling and termination, installation of data gathering panels, point to pointchecking, calibration of devices, system sequence of operation, integration on theworkstation level and fine tuning of the complete system.

In addition to the different levels that this document describes, a list of references of

all the designs and shop drawings is attached to this document along with samplesof each checklist and forms needed in order to achieve the Building ManagementSystem of The Pearl Qanat Quartier QQ01 Building (Apartment) J46.

3 DESIGN PARAMETERS

3.1 Specification Reference

The specifications for mechanical, electrical and plumbing services that apply to thebuilding management system are described in the document: The Pearl, DP/10Qanat Quartier Design Basis Report-Mechanical.

The building management system has been designed in a way to comply with all thespecification of the above document from all point of views: Field level, Automation

level and Management level.

3.1.1 Field Level

The controller FX16 Master Controller that Energy International supplies,comply with the MEP Services Specifications since it possess the followingfeature:

The FX16 is a protocol independent controller and can adapt to protocols

such as BACNET.

The FX16 allows up to 27 inputs / outputs with the additional possibility to

expand its I/O count through the standard XT / XP modules

The FX16 is freely programmable

The FX16 has a real time clock which allows introducing functions based

on a weekly time schedule

The FX16 is compatible with standard BAS (Building Automation System)

protocols, adaptable to any application and has a wide range of sensorsinput available

Fully programmable using FX Tools package

DIN rail mounting

Female connector option: screw or spring clamp connectors

Optional user interfaces: integrated, local, or remote

6/84


3.1.2 Automation Level

The BACNet is thus compatible with the automation level specificationssince the FX16 chosen for this project is fitted with a BACNetcommunication card. This card enables the FX16 controllers to pass datafrom one to another and to send event-initiated data to the Networkautomation engine in the METASYS System or to any other, off the shelf,BACNet supervisory system. Thanks to the BACNet features the FX16controllers have network input and output points which can be configuredto transmit and receive data over the BACNet Bus. The transmission of

point data is managed by the BACNet network and is independent fromthe supervisory functions of the METASYS Network Automation Engine. Anetwork of FX16 controllers, fitted with the BACNet communication card,can be installed to share analog and digital data between controllers on apeer-to-peer basis; a Network Automation Engine is not required unlessthe network is to be supervised by a METASYS system.Complex control strategy may now be performed in multiple FX16controllers without the need for network data exchange routines in asupervisory controller.

Moreover the FX16 controllers chosen for this project are UL listed andcomply with the temperature range as well as the memory required. Inaddition each of these controllers is equipped with a socket for connectinga commissioning service and has the required features as mentionedabove in the field level.

3.1.3 Management Level

The management level also goes along with the specification since eachpart of the management level has the requested specification. The

management level is made of the following items:

Network Automation Engine (NAE) manages facilities using information

and Internet technology and uses the communication technologies of thebuilding automation industry, including BACnet protocol, BACNETSnetwork, and the N2 Bus to monitor and supervise Heating, Ventilating,and Air Conditioning (HVAC) equipment, lighting and third partyequipment. A single NAE or a network of multiple NAE devices within abuilding provide monitoring and control, alarm and event management,data exchange, trending, energy management, scheduling, and datastorage.

(ADS) as a software management tool. The Application and Data Serveris the point of access into the building automation network and handlesthe archiving of historical and configuration data. The ADS capabilitiesinclude user graphics, alarm and event management, trend datapresentation, system summaries, reports, schedule configuration andsystem security. The ADS is a scalable platform that serves multipleconcurrent users that are connected with a Web browser. The ADSmanages the long-term storage of trend data, event messages, operatortransactions, and system configuration data. As Site Director, the ADSprovide secure communication to a network of Network AutomationEngines (NAEs). The ADS Web browser interface can be used to defineand modify online the METASYS system database

The System Configuration Tool (SCT) is included in the ADS software

package. It is used to create or modify databases in an offline mode, thento download them to the appropriate devices.

The METASYS user interface (UI) is web-enabled and provides a

powerful framework for navigating through the entire BMS, displaying

data, sending commands, and bringing critical information to the attentionof the operator. The user interface takes full advantage of the ADScapabilities.

The integration of Information Technology (IT) and Internet

communication and security technologies enables the ADS to be usedwithin the existing networking infrastructure of buildings and enterprises.The ADS can be accessed by multiple Web browsers from any locationon the network, and enterprise systems can read the data in the ADSdatabase for business planning and energy management purposes.

17/84


6 COMMISSIONING / TEST PROCEDURES

The commissioning of the BMS is divided into three successive phases.

6.1 Data Gathering Panel power test

The data gathering panel power test must be done after we make sure thatthe pre-commissioning forms, of the concerned DGP, have all been filled andsigned.

The power test procedure consists of:

Checking that the ground cable of the DGP is connected

Opening the 24VAC fuse of each controller of the DGP concerned

Requesting for power from CONSPEL person in charge

Checking the main power 230VAC on the supply of the DGP using a

multi-meter

Checking the low current 24VAC supply from the panel transformer

using the multi-meter

Closing all the 24VAC fuses of the panel

Checking the low current 24VAC supply to each controller andextension module

Upon the testing of these points, the top part of the checklist, EIC-FTC-XX-001/002/003 (where XX is the name of the building) in Appendix-E, must befilled.



18/84


6.2 Field devices/points commissioning tests

This part consists of the testing of both, the correct function of each fielddevice/point and the testing of the correct interpretation of its signal at theDGP.This procedure takes place after downloading the Input / Output program tothe controller and opening the commissioning software.Refer to the list below, to find the proper way of commissioning each kind offield device / point.

1.1 Binary or Digital Input

1. Choose one point

2. If the point is operational (ex: auto/manual switch that can be rotated) thenphysically alternate its state from the field

3. Check on the commissioning screen of the laptop is any value isalternating state

4. If yes, check that the software name of this software point coincide withthe field point we are testing

5. If the point indication is impossible to change, it can be simulated manually(this is done in general for all faults and alarms) and the same steps (3 &4) are continued

6. If the point is not operational, simulate a binary switch at the unit and labelNot Operational.

7. If the binary input comes from a sensor, check the list below for moredetails in testing and commissioning.

8. Note the input that has been verified by making a check against the deviceon the appropriate commissioning documentation. (See Appendix-E,checklist EIC-FTC-XX-001/002/003).



19/84


6.2.2 Binary Output

1. Verify proper interfacing device is installed. (e.g. Relay)

2. With power OFF at controlled devices , ensure the interfacing deviceresponds to a Software / Manual command. The software commandcomes from the commissioning software where as the manual commandcan be done by applying a jumper on the coil of the relay.

3. Note that the device has been verified by making a check against thedevice on the appropriate commissioning documentation. (See Appendix-E, checklist EIC-FTC-XX-001/002/003).

6.2.3 Analogue Input

1. Measure the actual input variable.

2. Check the value read on the commissioning tool, and verify that itcorresponds to the measured one

3. Check that the unit on the commissioning software point is matching theparameter we are checking.

4. Check that the input we are reading has a logical sense and does not fallout of common sense range.

5. If the analogue input comes from a sensor, check the list below for moredetails in testing and commissioning.

6. Note that the input has been verified by making a check against the sensoron the appropriate commissioning documentation. (See Appendix-E,checklist EIC-FTC-XX-001/002/003).



20/84


6.2.4 Analogue Output

1. Check that the unit on the commissioning software point is matching theparameter we are checking.

2. Send multiple different outputs.

3. Verify that the connected device is physically responding according toeach output sent

4. Calibrate the device if needed (in our case all valve actuators have beenmounted on their corresponding valves, tested and calibrated prior to theyuse on site).

5. If the connected device has a feedback, then check that the feedback ofthe device corresponds with the output sent.

6. Note that the output has been verified by making a check against theActuator Device on the appropriate commissioning documentation. (SeeAppendix-E, checklist EIC-FTC-XX-001/002/003).

N.B. While checking the analogue input and output, refer to the following listof sensors for calibration purposes



21/84


6.2.5 Duct Pressure Sensor

1. Verify that the sensor has been checked as installed in checklist EIC-PC-XX-001. (See Appendix-D)

2. Take from CONSPEL the list of all actual measured pressure across theneeded terminal connections as shown on sensor data sheets.

3. Compare the actual value of CONSPEL with that read on the propercommissioning tool. The pressure sensor is factory calibrated; therefore no

field adjustment should be necessary. The actual pressure is still beingtested. A list of value will be sent as soon as the values will be confirmed.

4. Go back to 6.2.3. Analogue Input, to finish step 6.

6.2.6 Duct Temperature Sensor

1. Verify that the sensor has been checked as installed in checklist EIC-PC-XX-001. (See Appendix-F)

2. Verify the sensor reading, by comparing the temperature read on theproper commissioning tool and the resistance measured on the terminalblock by the voltmeter. Use the table below (Figure-2: nominaltemperature vs. resistance) to check the matching.
