Structured Cabling System
Mandatory
Mandatory
64.02.01 General Description


The DoE Structured Cabling System (SCS) is compliant or exceeds the Australian Standard for Telecommunications Customer Premises Cabling (AS3080).

The SCS contains a Main Communications Room (MCR), previously referred to as the Campus Distributor (CD), remote Building Communications Room (BCR), previously referred to as a Building Distributor (BD) connecting to Telecommunications outlets (TO). The interconnection cabling is Campus Backbone Cabling (CBC) between distributors and Horizontal cabling from the MCR or BCR to the TO.

The primary location and quantities of distributors and outlets are defined within the EFSG and SCS along with the associated plans. Generally, as a guide the distance will be a radius of 70 metres between the outlet and the Communications cabinet in order to ensure a pathway no longer than 90 metres. If additional SCS are specified as part of the building works additional outlets will be defined as required of the service(s).

The NSW “Structured Cabling System Specification” defines the design plus the minimum quantity and quality of the components within the SCS. All communications cabling works performed for NSW DoE shall comply with this specification.

Civil and architectural requirements and business practices to cater for the installation of the SCS are described in the following sections.

Pathways - General
Mandatory
Mandatory
64.03.01 Campus/Building Pathways


Refer to NSW DET “Structured Cabling System specifications” for the provision of Campus/Building pathways.

Conduits for external underground horizontal cabling are to be minimum 100mm diameter white conduit marked by the manufacturer as being for communications use.  To limit drawing forces minimise the number of bends in the run.  Install cable pits adjacent to the buildings for cable drawing purposes, or use a sweep to enter the building where it is impractical to install pits.  Cables are not to be joined in cable pits.

A star topology will be used. Fibre will be run in underground conduit with an inspection pit system. Refer to SCS.

  • Provide pathways from this duct to the respective BD/BCR or CD/MCR to allow installed and future horizontal cabling to be installed.
  • Connecting pathways should preferably be accessible ducts so installed and future cabling can be laid in.  Provide 100% spare space.
  • If conduits must be used, they are to be white communications conduit of minimum length and run with a minimum number of sweeps so cables can be drawn in without exceeding the maximum pulling force.  Provide 100% spare conduits.
  • Provide an adequate number of connections to the skirting/wall duct to ensure there is 100% spare space within the communications channel.

Duct for Internal Use
As part of new or refurbished buildings install duct for the voice/data cabling and socket outlets with the following specification.

Selection & Design

  • Select ducting from a range that has factory made accessories including dowels, fishplates (to achieve bends and tees) and cable retaining pieces.
  • Provide cable retainers at maximum 900mm centres to hold the installed cables within the duct when a cover is removed.
  • Duct design must ensure that any screws used for fabrication or cabling retention do not penetrate into the duct to avoid damage to the communications cabling.
  • Two parallel continuous threaded screw flutes are required for fixing the cable retaining pieces.
  • Allow for future cables to be run using lay-in technique.
  • Provide each length of cover strip with points at both ends to allow removal of covers with a tool without damage to the paint finish. Alternatively the cover is to be affixed by screws designed for the purpose and colour coded.

Finishes:

The external surfaces for exposed duct are to be finished in baked powder coat enamel of selected colour.

Colours will be selected from the colour schedules specific to a project and more than a single colour may be required in a school.

64.03.02 Pathways- Campus Backbone Cabling (CBC)
 

The cable pathway installed for cabling can also be used for the cabling providing manufacturers’ cable installation specifications (e.g. minimum bend radius) can be achieved.  Ducts must be sized for the horizontal cabling, spare capacity and for the backbone.

Between buildings, conduits installed in the ground are the preferred pathways. Ducts installed in indoor-rated covered ways are an acceptable alternative. 

Conduits used for the CBC are to be a minimum 100mm diameter white conduit marked by the manufacturer as being for communications use.  To limit drawing forces minimise the number of bends in the run.  Install cable pits adjacent to the buildings for cable drawing purposes, or use a sweep to enter the building where it is impractical to install pits.  Cables are not to be joined in cable pits. Provide minimum 2 x 50mm diameter white conduits from pit to the site Campus Distributor within a building and minimum 1x50mm diameter white conduits from pit to each Building Distributor within a building.

CBC cables installed underground in conduit must be classified by the manufacturer as suitable for external underground use.

This section of DG 64 COMMUNICATIONS aims to assist planners in determining the brief for structured cabling, telephony, bell and PA systems as part of expand and refurbishment projects in existing schools. This section is not to be applied in any way to the requirements for new school construction as described in other sections of DG 64 COMMUNICATIONS.

Expand and refurbishment projects require a brief to be created that is directly applicable to the merging of the new works into the existing ICT infrastructure, structured cabling, telephony, bell and PA systems. Each site is unique, the scope will be determined by the Project Director in consultation with ITDs Foundation.T4L PMs, ICT Support Team Leaders and the Principal. Factors affecting the brief include:

  • impacts to existing voice and data, PA and bell system cabling to ensure ESFG standards and infrastructure compatibility across the site
  • suitability of existing ICT networking equipment and its compatibility with new equipment
  • suitability/expandability of any existing telephony, bell or PA systems through assessment based on age and future lifespan of the existing equipment.
  • suitability of existing structured cabling and its compatibility with new standards.
  • extent of the expansion and/or refurbishment
  • project budget
  • existing operational communication systems which the schools needs to retain (eg distributed signage or video systems).
  • planned future school expansion
64.05.01 General Requirements

New, upgraded or refurbished buildings must be delivered to current DoE requirements including communications services to the current Design Guide for a new school, including:
  • Data network
  • WiFi
  • Telephony
  • PA systems
  • Bell systems
  • Building Management and Monitoring systems including PV Solar systems
  • Digital signage
  • Security services routed over structured cabling such as CCTV

 The following examples are provided as a guide to the principles that should be followed.  It does not address all situations that will be experienced in the field. 

Requirement

Example

Current communication systems deemed suitable for expansion

Expand into new or refurbished buildings

Current communication systems deemed suitable but affected by building works

Relocate and upgrade if necessary. Expand into the new or refurbished buildings

Current communication systems deemed unsuitable for expansion

Uplift/ Replace across the entire site

Provide extension of the communications system in a new or refurbished building to allow it to function.

Expand/replace structured cabling, telephony, Bell, PA cabling to the building. Expansion capabilities or replacement of these systems is to be assessed.

Extend existing operational communications systems required by the school to the new or refurbished buildings to maintain present coverage and provide common supportable infrastructure across the site.

Upgrade existing ICT infrastructure to accommodate new equipment that is being installed. Upgrade of existing WAP’s and switches across the site for compatibility.

Expand schools digital signage system to include new or refurbished building.

Relocate existing communications systems where their operation is affected by the additional accommodation project.

Relocate site ICT services to either new or refurbished MCR/BCR/Floor Distributors that are affected by the works. This may include Bell, PA and telephony systems.

Provide electrical and data schematic drawings detailing the location of backbone pathways, existing outlets, data cabinets and other associated systems and any proposed changes prior to design signoff. 

Schematics for Expand and Refurbish projects must identify changes such as additions, removal and replacements of existing infrastructure along with new building inclusions. DoE ICT must be engaged in consultation  

 

The latest DoE Structured cabling System Specification must be adhered to in all the above scenarios. In practice this may mean that the communications works may extend outside the area of the building works.  Any required alterations to existing systems will form part of the scope for the specified work. This excludes repair or re-commissioning of existing defective systems which remains the responsibility of the school.

64.05.02 Structured Cabling works


Refurbished buildings are to be provided with structured cabling as for new school construction.  Installers should follow the structured cabling system described in this Design Guide.  All cabling work requires documentation including test results and “as built” diagrams, as per the Structured Cabling Systems Specifications.

Key elements include:

  • Schools network is to remain functioning during the constructions works. This may require temporary installations, or staged works to ensure the school remains operational with minimal interruptions.
  • Voice tie cabling may be required to connect via the existing block cabling to any existing analogue/digital (non VOIP capable) PABX.
  • Any MCR or BCR’s impacted by the project must meet EFSG requirements for new school construction.
  • Where there is additional equipment being installed in existing MCRs and BCRs, eg fibre backbone, horizontal cabling, phone controllers, CCTV head equipment, PA-Bell Controllers, etc, there may be a requirement to increase the room size, providing there is sufficient space to extend. The number and size of cabinets will also need to increase to accommodate the new services/equipment. Where possible SCS room layouts should be adhered to.
  • Make provision in the design for the structured cabling system to be extended to planned future buildings. This is critical for underground pit and conduit systems.
  • New campus backbone cabling is to be installed to current standards (pit and conduit system) and not utilise existing non-standard pathways. E.G conduits on covered walkways.
  • New horizontal cabling is to utilise cable tray system as per current standards.
  • Where existing data cabling is retained in a refurbished building (requires ITD approval), the cabling must comply with current SCSS standards.
  • Frequently the existing cabling will not have capacity for the extension and will require replacement.
  • Schematics must be provided for refurbished spaces indicating existing, new and changed data and power within the spaces.

 

Heritage buildings require specific solutions be developed in consultation with a heritage architect and shall be included in the developed brief.

64.05.03 Telephony Equipment


The PABX should utilise VoiP for internal handsets where possible. During the construction of the brief, the existing phone system is to be assessed. A determination will be made on expansion, upgrading or replacement depending on requirements and available PABX options for the site.

64.05.04 Reticulated Public Address (internal and external) and Period Bells


During the construction of the brief any existing services will be assessed. Should either system exist and be in use, its functionality must be retained or enhanced by the refurbishment accommodation work. This may involve upgrade or replacement of existing systems to accommodate project works, or relocation of the microphone and amplifier or period bell timer to a new administration block.  As well as retaining existing system/s, outlets are required to new or refurbished buildings in accordance with DoE requirements for new buildings

Period Alarms
Mandatory
Mandatory

Install period alarms in all primary and secondary schools. The period alarms are intended for the indication of events throughout the school from a central control point, usually the Clerical Office. The signal type and frequency of the period alarm will vary from site to site depending on the schools start and finish time, daily period program, assemblies, sports programs, the weather, evacuations and other unforseen emergencies.

Due to the relative complexity of the daily school program, specify and install a programmable timer to operate the period alarm system.

The alarm device type shall be agreed with DoE and will be at a minimum an under-dome bell contrived to be vandal resistant and weatherproof if externally located. Speakers, hooters and sirens may also be considered. The number and location of devices will be influenced by:

  • Background noise level. Materials Technology Spaces, playing fields, circulation areas and multi-purpose hall have considerably higher levels than the rest of the school and so will require more closely located or directional devices.
  • The need for some degree of sound isolation. Administration and, to a lesser extent, the library work areas need to function without the active disruption of alarm devices. Noise generated by reaction to the alarms in other areas can achieve the desired result.
  • The disposition of buildings on the site. Widespread buildings will require more devices than a tightly grouped layout, as will a multi-level site compared with a flat site.
  • The incidence of vandalism in the area. While some protection is afforded by height, in high-risk areas alarm devices may need to be further located in secure areas of the school, externally and internally, resulting in larger numbers of devices.

Generally, install period bells on the following basis:

  • Internally – one bell per building per floor, located in corridors, spaced to best utilise the effective range of the bell, typically no more than 15 metres from the end of a corridor and spaced at a maximum of 60 metres apart – in noisy locations one bell every 30 metres.
  • Externally – one bell outside the multi-purpose hall adjacent to the Canteen, one bell within each separate courtyard and one directed towards each major playing area.

The following limitations will apply:

  • Do not install a period bell in the administration, Canteen or library buildings. Bells located externally on the pupil side of administration block or adjacent buildings, or in adjacent corridors near libraries can achieve the desired result.
  • Where buildings are without corridors or corridors are adjacent to external walls, internal bells will not be required.
  • Where multi-storey buildings are without enclosed corridors, reduction in the number of bells may occur.

Place bells where the effective ranges can overlap to eliminate potential intermediate bell locations.

Depending on the location of buildings on site, the alarm devices may be wired directly back to the distribution board nearest the Clerical Office. Where voltage drop may be considered a problem, supply the devices from a local E.D.B., controlled from the control point.

Programmable Timer

The programmable timer must be a digital timer with the program capacity to store data for three different types of day (e.g. standard academic day, sports day, assembly day) in a standard weekly cycle. The unit must also have an inbuilt facility for manual actuation to allow for special period days and/or variations in the number of bells to be rung. Facility for the isolation of the output circuit during holidays or special period days is essential. Provide a rechargeable battery backup to retain the program and the correct time for at least 24 hours. The unit should be permanently connected and be separately circuited.

Programming the timer must be a relatively simple task. The timer shall also be able to provide a signal that can be used for the control of lighting.

Mount the timer within a recessed DIN enclosure with lift-up flap in the clerical office in the administration block.

Obtain the required programme from the school and program the timer.

Provide the school with three copies of the timer operating instructions including with each a copy of the installed program.
