Fire Alarm (addressable only)

  • Manufacturers:
    • Simplex (1st choice)
    • Notifier
    • Silent Night
  • Digital Transmitter (DACT) is to be integral addressable point reporting type.  Once points are programmed in the fire alarm control panel, these points are to be programmed in the Sur-Gard MLR2 Central Station Receiver at the Elon Security office as well by the fire alarm contractor.Note: Elon Electrical Department to provide Building account identification number when requested by fire alarm contractor.
  • Smoke detectors in bedrooms shall have programmable sounder bases (horn in base).  They shall be programmed for local base alarm initiation only at 2% smoke obscuration/foot and for system alarm at 5%.
  • All wires run plenum-rated wires with wall conduit stubbed out 6″ above finished ceiling.
  • Connect the Area of Rescue dry contact to channel three of the fire panel digital alarm communication transmitter so that security is notified by a fire alarm trouble signal that the area rescue system has been activated.

Computer Power

  • All designated computer sub-panels shall have a safety ground (this is usually the conduit system itself) to satisfy the NEC. A “clean” ground is to go back to service ground. It is to be sized the same as the phase conductor’s for a low resistance purposes.
  • All computer receptacles are to have isolated ground receptacles.
  • The grounding electrode system is to yield 5 ohms or less resistance to ground.
  • All computer sub-panel neutrals shall be at least the size of the phase conductor’s to allow for harmonic’s.

Receptacle Spacing

  • Offices shall have a minimum of one receptacle per wall space.
  • Classrooms shall have a maximum of 12′ of wall space between receptacles.

Switch Plate Covers & Outlet

  • Thermoset P-Line (Non Breakable), Manufactured by Pass & Seymour/Legrand

Wiring

  • There is to be no back wiring of any electrical devices. All connections shall be either wire-to-wire or wire-to-screw.
  • In all multi-wire receptacle circuits, the neutrals shall be joined together to a single wire. The device shall then be attached to this one neutral wire. This will eliminate feedback’s of higher voltages when changing the device in the future.
  • All above ground branch circuit joints shall be joined together with wire nuts. Sta-kons are not acceptable for branch circuit conductors.
  • Pre-wired flex conduit is acceptable for general receptacle and lighting wiring. Conduit is required from the subpanel to each room. Kitchens are to use conduit only to allow for future load.
  • The minimum size conduit is to be 3/4″.

Exposed Raceways

Any exposed surface raceway shall be run in a manner that will make it least noticeable. Such as running wire mold down in corners of the room and over to receptacle location. The purpose is to leave the wall space as open as possible for decorating purposes.

Panel Boards

  • Copper bolt in buss bars
  • “Square D” (preferred)

Metering

  • Each building should connect to the University’s energy management system so that energy consumption can be metered individually by building.
  • Monitor total electric, natural gas, domestic water, and solar DHW (if used) at a minimum.
  • Use btu meter for HW or CHW and totalizing Onicon meters for water and natural gas.
    The resolution for water should be 1 gal/pulse for low use buildings and 10 gal/pulse for larger flow (dormitories); natural gas 1 ft3/pulse.
  • Use Shark 100-S -60 -10 –V4 –WIFI for electrical metering. All the data is to be connected to the building automation system and be served to Duke Energy and Lucid Technologies in XML format.
