Hardwired Digital, Building-Wide Integration, Network Based. 

For Phased Construction: Ensure all phases of work receive network lighting control systems by a single, common manufacturer.

*nLight is the basis of design for the purpose of system performance and construction documents including wiring diagrams, device legends, specifications, and sequence of operations capabilities, so that nLight and other approved manufacturers listed in a project’s final construction documents may be equally considered.

Description

Digital, networked lighting control devices consisting of power relay packs connected to sensors, switches, auxiliary relays, etc., and networked devices such as bridges and the system controller typically through CAT-5e or similar cable.  Programming settings reside at the device level (such as relay power packs, sensors and switches), with the exception of timeclock events and system-wide profiles, which may reside at the system controller level.  

System Controller

• The System shall include a front-end network interface management device which provides direct, native BACnet IP interfacing and Building management interface with BACnet IP. The system controller shall be BACnet Testing Laboratories (BTL) listed.
• The system controller provides timeclock capability, system-wide profiles, and means for programming and updating firmware of lighting control devices.
• Place in NEMA 1 enclosure. Locate within an electrical room or other space as directed by Engineering Services Electrical Group, but not within telecom rooms.  The system controller shall be located no more than 72-inches above finished floor. 
• The system controller device must be dedicated to lighting control devices and not used as the controller for non-lighting building systems.
• Where a wireless dongle is used for programming, disconnect after commissioning and locate adjacent to the system controller.
• Example: nLight Eclypse, 24V AC/DC, with Linux-based (non-Windows-based) operating system. 

Interface with HVAC

Connect the system controller via BACnet to the building automation system so that occupancy sensor information may be communicated.  In addition, provide secondary means of HVAC interfacing: provide occupancy sensors with auxiliary contacts or power relay packs with auxiliary contacts as necessary to provide the status of space occupancy information.  Confirm in design.  Networked lighting control systems shall not be used for purposes other than lighting control unless otherwise approved by Engineering Services Electrical Group.

Where Audio/Video Interface is required

Lighting control systems and audio/video systems, including shade control should typically be independent systems unless prior approval is given by Engineering Services Electrical Group.  Refer to approved Hardwired Networked Lighting Control System manufacturers and use devices by these manufacturers to accomplish interface.  Discuss Crestron for portions of the building where Audio/Video interface is required.

Hardwired Standalone Lighting Control Systems (Non-Networked)

These systems are the same as Hardwired Networked Lighting Control Systems, described above, except there is no need for a system controller and other lighting controls network devices (such as bridges) unless those parts are necessary for the project’s sequence of operations (like timeclock). Hardwired Standalone Lighting Control Systems do not connect to the BAS, thus are “Non-Networked” even though cable such as CAT-5e or similar is used to connect lighting control devices amongst themselves. The system shall be capable of scaling to become a Hardwired Networked Lighting Control System.

Provide means of HVAC interfacing: provide occupancy sensors with auxiliary contacts or power relay packs with auxiliary contacts as necessary to provide the status of space occupancy information. Confirm in design.

Wireless Networked Lighting Control Systems

Wireless systems will not be accepted unless prior approval is given by Engineering Services Electrical Group. Discuss proposed wireless lighting controls prior to developing schematic basis of design documents or pricing documents.

Wireless systems may be considered based on the building spatial functions, as well as constructability within the facility. The University is restricting the deployment of wireless control systems within facilities and spaces where research is being performed due to possible interference and security issues. Where deployed, wireless system devices (wall box controls, interfaces, etc) are preferred to require a line voltage source for power and not solely battery operated. Battery operated devices shall be avoided unless approved by Engineering Services Electrical Group. Self-generating power sourced devices will be considered and approved on a case-by-case basis. 900 MHz or 300 Mhz nominal is required. All wireless systems must obtain prior approval from Engineering Services Electrical Group and Facilities Automation Services. Where a network based system is warranted, refer to system controller requirements under the Hardwired Digital, Building-Wide Integration, Network Based Systems section. Where batteries are provided, provide a note requiring the Contractor to document the serial numbers, battery type, as-built locations of every battery-powered lighting control device and battery inverter and provide this information to Engineering Services Electrical Group and Penn State OPP Work Control for Preventive Maintenance purposes of battery group-replacement at 90% of rated battery life.

Power Over Ethernet (POE)

POE is not acceptable because of programming and maintenance challenges.

Standalone Analog Lighting Controls

Standalone Analog Lighting Controls are typically line-voltage devices not part of a lighting network.  These may be deployed in limited areas in new construction and major renovations (such as mechanical rooms); in smaller renovations to supplement the reuse of existing stand-alone lighting controls; and in maintenance applications.  Provide means of HVAC interfacing: provide occupancy sensors with auxiliary contacts or power relay packs with auxiliary contacts as necessary to provide the status of space occupancy information. Confirm in design.

Approved System Manufacturers:

Wattstopper, Sensor Switch, Leviton, Lutron, and additional manufacturers as approved by Engineering Services Electrical Group.  Discuss design with Engineering Services Electrical Group.

DMX

DMX systems will not be accepted unless prior approval is given by Engineering Services Electrical Group.  Discuss proposed DMX system prior to developing schematic basis of design documents or pricing documents.  Where approval is given, look for design techniques to simplify and limit the deployment of DMX devices. 

DALI

DALI systems and proprietary DALI-like systems will not be accepted unless prior approval is given by Engineering Services Electrical Group.  One reliability concern is loss of system functionality when communication to the central processor is lost.

Control System Deployment

Hardwired Networked Lighting Control Systems shall be deployed at:

• New Buildings
• Major renovations of greater than 75% of one floor level or more than 10,000 square feet.

Notes:

• Smaller renovations must typically have hardwired standalone lighting control systems.
• Smaller renovations may reuse existing lighting controls, including analog controls, if current energy codes are met.
• For maintenance of existing controls: Replace devices in kind and program as necessary to achieve original functionality.
• Discuss with Engineering Services Electrical Group any proposed deviations from this approach in design prior to bid. 
• Perform due diligence to determine if connecting to existing networked lighting control system, if any exists in the building, is feasible and practical. Coordinate specification of new system with Engineering Services Electrical Group.
• Phased construction: Ensure all phases of work receive network lighting control systems by a single, common manufacturer. For phased construction, the system may start as a hardwired standalone lighting control system deployment.  However, the network cabling and components shall be included as part of the project and completed based on the building phasing approach. Provide network cabling routing/connections above ceiling and extend network cable to electrical room as provision for final system controller. The terminations and connections to the system controller shall be made in appropriate future phase. Ensure final commissioning of the multi-phase project is performed.
