TerminologyTerminology• Coverage area: it is the area served by the BAS device.• Coverage area cable: a cable connecting the BAS• Coverage area cable: a cable connecting the BAS
outlet/connector or horizontal connection point to a BAS device.
• Horizontal Connection Point (HCP): it is the location for connections between horizontal cables that extend from building pathways and horizontal cables or coveragebuilding pathways and horizontal cables or coverage area cables that extend to building automation systems devices and equipment.

Additional Factors
Office 25 In open office environment, coverage area sizes will be typically greater than in a dedicated office space.
Indoor Parking 50
Identify fire, security, carbon monoxide and HVAC.Note: may also require voice connections for security.
Retail 25 Security requirements may increase the coverage area density (e.g. CCTV, alarm and access).
Factory 50 Coverage area size may vary according to manufacturing processes, environment and building design
Coverage area requirements may vary if BAS services have centralized control (e g HVACHotel 25 Coverage area requirements may vary if BAS services have centralized control (e.g. HVAC, fire alarm and access).
Classroom 25Coverage area requirements may be centralized for security and access controls. Plan for the unique BAS requirements for each area types (e.g. fire alarm,, access control and HVAC).
Hospital 25Coverage area density is averaged to compensate for a variety of environments (e.g. patient rooms, labs, emergency room and operating room). Plan for the unique BAS requirements for each area types.
Mechanical Equipment 5 Determine location of air handlers, chillers, boilers pumps, fans, compressors, etc. Air Equipment Room
5 handlers will typically have a higher concentration of BAS devices.

Pathways and SpacesPathways and Spaces• Pathways and spaces specific to BAS is now in
the draft ANSI/TIA-862-A• Zone Box – location of the HCP
– Specific to BAS in the TIA TR 42 standards documentsBecause a zone box if used is inserted in the– Because a zone box, if used, is inserted in the “Cabling Subsystem 1” infrastructure and does not enclose active equipment, it can not be considered as a Telecommunications Enclosure (TE) and does not have to meet the same requirements of a TE

The “Green” eraThe Green era• Shared infrastructure
ll bl– smaller cables– shared telecommunications spaces
• Integration of systems– fewer equipment– storage servers (more data in less spaces)
• Reduction of carbon footprintp– remote access to multiple site networks
• Control on usable energylights control– lights control
– environment control• BASs are currently eligible for LEED credits
In SummaryIn Summary• BASs are part of the near future
