- GENERAL
- Networking and Telecommunications, a unit of Computer Services at Missouri State
University; is involved in providing the following services for buildings on the Missouri
State University campus:
- Telephone service, including indoor and outdoor emergency telephones and
rescue assistance communication
- Data connections to the campus network, including wireless access points
- Electronic access control associated with the Bear Pass
- Security cameras
- Discussions with Networking and Telecommunications and the end users shall be held
early in the design of a project to make sure the needs and expectations of the end
users are made clear and to understand what facilities Networking and
Telecommunications will require in order to provide the necessary service. The
Project Manger shall be the lead in facilitating these discussions.
- BUILDING INFRASTRUCTURE
- Fiber and copper connections to the campus voice and data systems are typically
brought into the building at a single location in a voice/data room. The contractor is
typically required to provide the raceway into the building. Networking and
Telecommunications will pull the fiber and copper lines into the building and terminate
them in a voice/data room. An equipment rack will be installed in the room to provide
distribution of voice/data systems to the building. Equipment racks are typically
furnished and installed by Networking and Telecommunications.
- The contractor is required to provide all boxes and raceways for the voice/data
systems, including access control and security cameras. Conduits shall be a minimum
1” diameter unless noted otherwise on specific details. A cable pathway consisting of
conduits, J-hooks, and/or cable trays must provide a continuous path from every
location of service back to a voice/data room. Data, voice, CCTV and access control
typically share the same cable pathway. Cabling shall not be allowed to run loose, lay
on ceilings, or be attached to other conduit and piping, etc. The cable path must be
clearly indicated on the bid documents. During construction the entire cable pathway
must be in place prior to beginning any voice/data wiring.
- Time must be allowed during construction to accommodate the installation of
the voice/data wiring in the building. Make sure that the construction schedule
allows for this work. After award of the construction contract, make sure that
the contractor provides a construction schedule and within that schedule
indicates time to allow Networking and Telecommunications to wire the building
and to finish out the installation. Coordinate with Networking and
Telecommunications to establish their time needs and continue to
communicate with them throughout construction to ensure they are informed of
the schedule as construction progresses.
- Voice/Data wiring shall begin after the cable pathway is fully in place
but before ceiling grid is installed. Drywall is also typically in place at
this stage. Final wiring, which includes installation of the jacks and
coverplates, typically occurs after painting is complete and the
building is free of excessive dust.
- Provide sleeves through the walls, floors, and ceilings of voice/data rooms as
necessary to provide a continuous cable pathway. Provide the size and quantity of
sleeves at each location where they are required as appropriate for the number of
cables expected to pass through the construction. Consult with Networking and
Telecommunications to determine the quantity and size of sleeves required. Sleeves
through fire rated construction must be fire stopped.
- J-hooks are the preferred means of providing cable support above accessible lay-in
ceilings. Space J-hooks a maximum of 48” on center. At changes in direction,
Jhooks must be located not farther than 12” on each side of the change in direction.
- Where a cable pathway must cross above an inaccessible ceiling, such as a drywall
ceiling, provide a conduit or multiple conduits to carry voice data wiring above the
inaccessible ceiling. Conduits shall be run as straight as possible. All bends in the
conduit shall be sweep elbows and shall be kept to a minimum. In no case shall there
be more than 180 degrees of total bend in a conduit unless a junction box is provided
to act as a pull box. Size the conduit(s) to accommodate the anticipated number of
cables that will be installed in the cable pathway. Consult with Networking and
Telecommunications to determine the quantity and size conduits that may be required
across an inaccessible ceiling area. Ends of conduit shall be de-burred and shall be
provided with bushings to protect cables from damage.
- Voice/data cables shall not be painted. Where the cable pathway is exposed, conduit
shall be used as the cable pathway if it is desired that everything in the exposed area
be painted to match the surrounding surfaces.
- VOICE/DATA ROOMS
- Every building must have at least one location to house central voice/data equipment
such as the service demarcation, equipment racks, data switches, access control
equipment, etc.
- Except for in very small facilities, it is strongly preferred that the voice/data room be
dedicated to housing voice/data equipment. Do not make an exception to this rule
without consulting with Networking and Telecommunications. Do not share voice/data
rooms with custodial closets, rooms where equipment might become wet, or rooms
that might become excessively hot or cold.
- Generally, the minimum size voice/data room is approximately 6’ wide x 8’ deep x 8’
high. The actual quantity and size of the required voice/data room(s) depends on
many factors such as overall building size, number of stories, floor plate size and
layout, the density of the services required, etc. It is important to involve Networking
and Telecommunications early in the design process so these rooms can be
accommodated as the floor plans are developed.
- Voice/data rooms will typically house at least one wall mounted equipment rack that is
approximately 24” x 24” and hinges open for access to the rear of the equipment. This
is generally mounted in the center of one wall to allow the rack to swing open and
provide space for a technician to access the rear of the rack when it is open.
- Voice/data rooms shall also have the following characteristics:
- Line all walls with ¾” thick, fire-treated plywood. The bottom of the plywood can
be mounted 12” above the floor and the top shall extend to at least 8’ above the
floor. The plywood provides a solid surface for mounting the equipment rack and
other equipment enclosures such as the service termination equipment, access
control equipment, grounding buss, security camera equipment, etc.
- Provide at least one 120-volt, 20 amp quad-plex receptacle on each wall in the
space. The receptacles in the space shall be on a circuit dedicated to the voice
data room and shall be provided with an isolated ground. Emergency power is
typically not required but is desirable if it is available.
- Provide each voice/data room with a grounding buss. The grounding buss shall
be a minimum of 4”x12”X1/4” thick and shall be mounted to the wall on standoffs. Where multiple voice/data rooms are provided in a building, the grounding
buss shall be bonded to the communication grounding system. The
communication grounding system shall be constructed in accordance with the
National Electric Code. The grounding system shall be bonded to the grounding
system at the building electric service entrance.
- Provide good lighting. Control lighting with an occupancy sensor or digital time
switch so lighting is not left on indefinitely while the room is unoccupied.
- The room shall be provided with air conditioning. In most cases voice/data
rooms are not required to be equipped with a dedicated air conditioning system
but careful consideration shall be given to the type of space that shares a
thermostat with a voice/data room. Do not share a voice/data room with a zone
that may require heating since voice/data rooms do not typically require heating.
- Do not run piping through voice data rooms. This includes piping for domestic
water, hot water heating, chilled water cooling, drain piping, steam and
condensate, fire sprinkler, etc. Do not install equipment in or above a voice/data
room that might leak or sweat. Water can cause serious and expensive damage
to voice data equipment and create a major inconvenience to building occupants.
If a voice/data room must be equipped with a fire sprinkler it is preferred to
provide a sidewall sprinkler in order to keep piping out of the room if possible.
- Provide a lockable, self-closing door. Door hardware shall have a storeroom
function. Keying shall match other voice/data closets on campus.
- TECHNOLOGY ROUGH-INS
- Technology rough-ins typically consists of a 4” square box with a single gang plaster
ring. A 1” diameter conduit shall be run from the box to the nearest cable pathway that
provides the most practical route to the nearest voice/data closet. The ends of all
conduits shall be de-burred and shall be provided with a bushing to protect voice/data
cables from damage. Each rough-in shall have a dedicated conduit between the box
and the cable pathway. Rough-ins shall not be “daisy chained”. Keep bends to a
minimum and provide intermediate pull boxes where an excessive number of bends
are required. Networking and Telecommunications has the ability to provide up to six
(6) jacks (voice and/or data) in a single gang coverplate.
- Where floor boxes, surface raceway, modular offices systems that include a
wiring raceway, or furniture that includes wire management are used, they
must be able to accommodate Systimax jacks. Care must be taken when
selecting and specifying these items, especially if they are provided with a
special faceplate that fits to the floor box, surface raceway box, or furniture
wireway. Many manufacturers make faceplates to accommodate Systimax
jacks; it is simply a matter of specifying the correct faceplate and then verifying
during the submittal process that the correct faceplate is being provided.
- Rough-ins for cameras and wireless access points that are shown to be
installed in lay-in ceilings do not require that the rough-in be installed in the layin ceiling tile. In
these cases, the rough-in can be installed just above the
location of the camera or wireless access point and a short plenum-rated patch
cable will be used to connect the device to the outlet when it is installed.
- Cameras do not require a separate power connection at the camera
location but use Power-Over-Ethernet (POE). For outdoor cameras
a power injector must be installed to provide power to the camera.
These power injectors shall be located in the nearest voice/data
closet. Coordinate the locations for the power injectors closely with
Networking and Telecommunications. In instances where the
nearest available location for a power injector is excessively far from
the camera location, a power injector may have to be located outside
of a voice/data closet in a location nearer to the camera. For outdoor
locations remote from any building, this may require mounting the
power injector in a weatherproof enclosure located outdoors. These
exceptions must be discussed with Networking and
Telecommunications during design.
- Wireless access points are best mounted on a horizontal surface. Any
exceptions to this must be approved by Networking and Telecommunications.
- Card Reader locations require a more extensive rough-in than other technology
rough-ins. Refer to the specific details for the rough-in and wiring of card
readers and their associated electronic access control equipment.
- The following schedule indicates rough-ins for technology typically provided on a
project. Every project may not have a need for all of these items.

- The symbols in the above schedule shall be used on the plans to indicate the
type, location, and quantity of technology rough-ins required for the project.
- Locations of rough-ins, types of rough-ins, and quantity of cables pulled to each
outlet, as well as the number of VOIP phones at an outlet shall be determined
during the design process. Generally speaking, the following project
stakeholders shall be involved in determining the locations quantities:
- Voice Rough-ins (Analog) - Networking and Telecommunications and
the representative(s) of the end users.
- Fire alarm panels require two (2) analog phone lines to
provide a means of reporting to Safety & Transportation
.
- Emergency phones in elevators and other any locations
require an analog phone line per emergency phone to
provide voice service. For elevators this jack is provided in
the elevator equipment room.
- If the project includes any other equipment that reports to a
monitored location via telephone, verify the type of phone
line required and note it accordingly on the bid documents.
- Fax machines require an analog phone line.
- Data Rough-ins – Networking and Telecommunications and the
representative(s) of the end users.
- Keep in mind that in addition to providing a data rough-in
at each location where there might be a networked
computer workstation, data outlets are also required at any
networked printer, scanner, or copy machine. Verify any
locations such as these where data might be required with
the representatives of the end users.
- Data rough-ins are required at each instructor’s station in a
classroom equipped with audio/visual technology.
Typically an instructor’s station requires two (2) data
cables however; an instructor’s station in an ITV equipped
classroom requires three (3) data cables. Verify these
requirements with Classroom Instructional Technology
during the design process. Note that conference rooms or
auditoriums equipped with audio/visual technology may
also require data connections. Verify those requirements
with the A/V system designer and the representative(s) of
the end user.
- Data rough-ins are also necessary to connect the building
temperature controls system to the central facility
management system to allow the building temperature
controls to communicate with central monitoring
workstations. This typically occurs in only one location in a
building but more than one location may be necessary in
larger buildings or buildings where the layout dictates.
These connections will require a fixed IP address be
assigned to the jack. The IP address must be set up at the
time the equipment is connected to the network and the IP
address provided to the temperature controls contractor.
Coordinate this effort with Networking and
Telecommunications. Verify the location where these are
required with the temperature controls contractor.
- Camera Rough-ins – Networking and Telecommunications, Safety &
Transportation, and the representative(s) of the end users.
- Wireless Access Rough-ins – Networking and Telecommunications.
This also requires a conversation with the representative(s) of the
end users to verify how heavy they anticipate the usage of the
wireless network will be. For instance, if a department is requiring all
of their students to use tablets for electronic textbooks or laptops for
recording lab data, Networking and Telecommunications needs to be
aware so they can plan the density of the wireless coverage
appropriately.
- Card Reader (Electronic Access Control) – Networking and
Telecommunications, Safety & Transportation, and the
representative(s) of the end users.
- Data and VOIP Phone - Networking and Telecommunications and
the representative(s) of the end users.
- In the case of these outlets, the quantity of cables pulled
to the rough-in is equal to the prefix indicated for the Data.
The prefix for the voice over IP phone indicates the
number of phones that will be plugged into this outlet.
The prefix before the VOIP Phone must always be equal
to or less than the prefix before the data. A voice over IP
phone plugs into a data outlet and if a networked
computer is also required at that location, it is plugged
into the VOIP phone.
- ELECTRONIC ACCESS CONTROL
- Missouri State University uses a system from S2 Security Corporation for electronic
access control. Students, faculty, and staff are issued a Bear Pass card that includes
the technology required to allow the card to be programmed with the credentials
necessary for access control. Guests to the University may also be issued a Bear
Pass card for their use when deemed appropriate. The system employs a “Tap & Go”
card reader to convey the user’s credentials to the system when access is requested.
Note that Residence Life and Services and the Jordan Valley Innovation Center use a
system other than this for their electronic access control. When working on projects
with those entities, verify their requirements during the design as they may differ from
the requirements outlined here.
- The contractor is responsible for providing the system of raceway and boxes
necessary to accommodate the access control system at locations where
electronic access control is required. Refer to the detail included in this
standard for rough-in of card readers and their associated electronic access
control equipment.
- The contractor shall also provide the hardware necessary to monitor door
position and request-to-exit, to properly lock and unlock the door, and to
provide power transfer to the hardware as required. Hardware specified for
these functions must be reviewed during the design process with Networking
and Telecommunications as well as the University Locksmith. Refer to the
details included in this standard for hardware and wiring for the access control
system at doors.
- Networking and Telecommunications will provide the central access control
equipment, the card reader, and the hybrid cable for the access control
equipment. Networking and Telecommunications will typically pull the hybrid
cable to the door location and leave enough cable coiled above the ceiling near
the door to reach each of the devices at the door. Networking and
Telecommunications will typically terminate the wiring on the card reader and
install the card reader.
- The contractor shall remove the outer jacket from the hybrid cable and
separate the cable into its individual cables in the junction box above the head
of the door. Care shall be taken not to damage the jacket or shield on any of
the individual cables. The contractor shall then pull each cable to its
associated device and terminate the cable except that the cable to the card
reader shall be pulled to the junction box for the card reader and left coiled in
the box. As noted above, Networking and Telecommunications shall terminate
the cables on the card reader and install the card reader on the box. The
contractor shall coordinate the installation and commissioning of the system
closely with Networking and Telecommunications.
- Hardware shall fail in the secure position. Networking and
Telecommunications will provide a 24-volt unlock signal to unlock an electronic
lockset or electronic strike. This signal can power devices requiring 3 amps or
less to operate. Electronic locksets are the preferred means of controlling
access at most doors where electronic access control is required. These shall
be provided with an integral request-to-exit contact and a door position monitor.
Where electronic strikes must be used, a separate request-to-exit sensor and
door position monitor must be provided.
- Where an exit device is used, it must be provided with its own power supply
that is compatible with the device. This will require that 120 volt power is
brought to the power supply. In this case, Networking and
Telecommunications will provide a contact closure to signal the device to
unlock.
- Magnetic locks shall not be allowed.
- In cases where electronic access control is used at gates, turnstiles, or other
specialty equipment; the selection and specification of the equipment shall be
discussed with Networking and Telecommunications during the design process
as well as during construction and commissioning.
- OUTDOOR PEDESTAL-MOUNTED EMERGENCY PHONES
- Missouri State University uses an outdoor pedestal-mounted emergency phone
manufactured by Talk-A-Phone. The phone features an ADA compliant, pushbuttonactivated, hands-free emergency phone; a blue beacon on top of the pedestal; and also
includes a loudspeaker to provide mass notification announcements.
- Networking and Telecommunications shall furnish the unit and the anchor bolts.
- The contractor shall provide a concrete base and install the anchor bolts that
are furnished with the unit. The contractor shall also provide one (1) dedicated
120-volt, 20 amp circuit for power and a 1-1/2” conduit from the base of the unit
to the nearest voice/data cable pathway.
- The contactor shall assist Networking and Telecommunications in mounting the
unit on the concrete base and connecting power to the unit. Networking and
Telecommunications shall pull the voice and data wiring to the unit, terminate
the voice and data connections, and program the unit.
- Coordinate the location and infrastructure requirements for these units closely with
Safety and Transportation as well as with Networking and Telecommunications.
- INDOOR EMERGENCY ASSISTANCE PHONES (RESCUE ASSISTANCE COMMUNICATION)
- Indoor emergency assistance phones shall be an ADA compliant, pushbutton-activated,
hands-free emergency phone with stainless steel face and LED indicator light. Phones
shall be flush-mounted if possible. Indoor emergency phones shall be installed at
designated areas of refuge to serve as the code required two-way communication
system for the area of refuge.
- Networking and Telecommunications shall furnish the unit and its associated
flush-mounted back box.
- The contractor shall install the flush-mounted back box and a 1” conduit from
the back box to the nearest cable pathway providing the most practical route to
the nearest voice/data closet. The ends of the conduit shall be de-burred and
shall be provided with a bushing to protect voice/data cables from damage.
- Networking and Telecommunications shall install the voice wiring to the phone
and shall install and program the phone.
- The faceplate of these units typically includes raised or engraved letters and Braille
indicating the unit is an emergency phone but do not include the informational or
instructional signage required by code for areas of refuge.
- For phones serving as the two-way communication system for an area of
refuge, the design team shall specify the appropriate signage for the contractor
to provide separately from the emergency phone. The signage shall include
instructions and other verbiage as required by code. The signage shall be
indicated the plans with the other building wide room signage and shall be
specified to match the building wide room signage for consistency throughout
the building.
- Coordinate the location of these units with Safety and Transportation as well as with
Networking and Telecommunications.
