2、egrating fire alarm systems with building automation systems can result in many economic and operational benefits. Such integration requires communication standards and careful design practices. BACnet is an internationally recognized communication protocol standard specifically designed for integra

3、ting building automation and control systems. Thousands of BACnet systems can be found around the world, and its popularity is growing. Newly proposed additions to BACnet make it very well suited for integrating fire alarm systems with building automation systems.Maintaining the integrity of fire al

4、arm systems when they are integrated with other building systems requires more than just communication standards. Best design practices, appropriate testing procedures, and modernized building are also needed.The technology of building automation and control systems has advanced rapidly over the pas

5、t fifteen years. Todays technology provides building owners and designers with a rich assortment of options and flexibility. Powerful personal computer workstations and intelligent distributed controllers that process complex algorithms quickly and efficiently characterize state-of-the-art building

6、automation and control systems. These advances have taken place across a variety of building services including heating, ventilating, and air conditioning (HVAC) control systems, lighting control systems, access control systems, and fire alarm systems.In spite of these advances, building owners have

7、 been frustrated by the inability to bid projects competitively and to integrate innovative products made by different manufacturers in ways that best suit the unique needs of their facility. The main obstacle has been incompatible proprietary communication protocols. The adoption of BACnet as the s

8、tandard communication protocol for integrating building control products has changed the industry and opened the door to new innovation in building control technology and true integration of previously isolated building systems.In the United States, the National Electrical Manufacturers Association

9、(NEMA) Signaling, Protection, and Communication Section (3SB) has endorsed the use of BACnet as the preferred way to integrate fire alarm systems with other building control systems. The National Fire Protection Association (NFPA) is in the process of revising NFPA 72 to address design issues relate

10、d to integrating fire alarm systems with other building systems. First-generation BACnet fire alarm system products are already available in the marketplace in the United States and in Europe. These are clear indications of interest in integrating fire alarm systems with other building systems and i

11、n using the BACnet protocol as a means to accomplish that goal.A BACNET OVERVIEWBACnet is a standard communication protocol developed by the American Society of Heating Refrigerating, and Air-Conditioning Engineers (ASHRAE). It has been adopted as a prestandard by the European Community and has been

12、 proposed as an ISO standard. Today there are over 70 companies with registered BACnet vendor identifiers. These companies are located in North America, Europe, Asia, and Australia. Commercial BACnet product offerings range from gateways that connect proprietary systems to complete product lines tha

There are thousands of installed systems ranging in complexity from a single gateway to very large office buildings with top-to-bottom native BACnet systems, to campus or city- wide systems linking multiple buildings. BACnet products includ

14、e HVAC controls, lighting controls, access controls, and fire detection systems.Fundamentally, BACnet, like any communication protocol, is a set of rules that provide a way to exchange information. BACnet was designed and optimized specifically to meet the needs of building automation and control ap

15、plications, and to convey the data needed by these applications including, but not limited to, hardware binary input and output values; hardware analog input and output values; software binary and analog values; schedule information; alarm and event information; files; and control logic. BACnet does

16、 not define the internal configuration, data structures, or control logic of the controllers.BACnet is designed to be scalable from very small, low-cost devices to very large complex systems that may involve thousands of devices and multiple buildings located anywhere in the world. It achieves this by combining an object-oriented representation of the information to be exchanged, flexible choices for local area netw
