These are the minimum requirements only. In view of the rapid changes in the field of controls and related technology, the BMS installation contractor shall include for the latest technology and systems available from the specified manufacturer at the time of tender. The Contractor shall allow the costs related to loading the latest version of software available at the time of handing over of the installation.

The Building Management System (BMS) shall be comprised of Network Area Controller or Controllers (NAC) within the facility. The NAC shall connect to the owner’s local or wide area network, depending on configuration.

Access to the system, either locally in each building, or remotely from a central site or sites, shall be accomplished through standard Web browsers, via the Internet and/or local area network. Each NAC shall communicate to LonMark/LonTalk (IDC) and/or BACnet (IBC) controllers.

BMS DESIGN PARAMETERS

The proposed BMS system and components shall be compatible with a wide variety of control devices using BACnet, LON, Ethernet TCP/IP, ModBus and OPC standard for open system communications and other current international communication standards. The BMS shall be capable of being extended with controllers on the BACnet protocol and the LON bus. The BMS shall allow integrating future BACnet controllers on the process level.

Using appropriate hardware, the system shall be Listed by Underwriters Laboratories Inc (ULI) or approved equal for use in energy management (category PAZX), critical process (category QVAX), security (category APOU), and as the primary control and monitoring device for smoke control (category UUKL) and fire alarm systems (category UOJZ).

OPEN, INTEROPERABLE, INTEGRATED ARCHITECTURES

The intent of this BMS specification is to provide a peer-to-peer networked, stand-alone, distributed control system with the capability to integrate both the ANSI/ASHRAE Standard 135-1995 BACnet and LonWorks technology communication protocols in one open, interoperable system.

In addition, adherence to industry standards including ANSI / ASHRAE™ Standard 135-1995, BACnet, Lontalk, and LonMark to assure interoperability between all system components is require For each LonWorks device that does not have LonMark certification, the device supplier must provide an XIF file for the device. For each BACnet device, the device supplier must provide a PICS document showing the installed device’s compliance level. Minimum compliance is Level 3; with the ability to support data read and write functionality. Physical connection of BACnet devices shall be via Ethernet.

All components and controllers supplied under this contract shall be true “peer-to-peer” communicating devic Components or controllers requiring “polling” by a host to pass data shall not be acceptable.

The supplied system must incorporate the ability to access all data using standard Web browsers without requiring proprietary operator interface and configuration programs. An Open DataBase Connectivity (ODBC) or Structured Query Language (SQL) compliant server database is required for all system database parameter storage. This data shall reside on a supplier-installed server for all database acc Systems requiring proprietary database and user interface programs shall not be acceptable.

A hierarchical topology is required to assure reasonable system response times and to manage the flow and sharing of data without unduly burdening the customer’s internal Intranet netw Systems employing a “flat” single tiered architecture shall not be acceptable:

Maximum acceptable response time from any alarm occurrence (at the point of origin) to the point of annunciation shall not exceed 5 seconds for network connected user interfac

Maximum acceptable response time from any alarm occurrence (at the point of origin) to the point of annunciation shall not exceed 60 seconds for remote or dial-up connected user interface
