The Quadram Institute, located at Norwich Research Park, opened in May 2018. Among its facilities, it boasts one of Europe’s largest gastrointestinal endoscopy units and clinical research facilities. The building showcases the flexibility of Prolojik’s lighting control system, demonstrating DALI lighting, Central Battery Integration, BACnet and IP integration, along with EnOcean energy harvesting user control.
Lighting control
The project integrates 3,000+ DALI luminaires into Prolojik’s DALI controllers. Over 100 DALI networks are connected to an Ethernet network using TCP/IP area controllers. Control for occupancy and daylight is achieved by over 600 conduit box-mounted DALI multi-sensors, which are designed to fit directly into BESA enclosures, making them ideal for exposed ceilings.
Central battery integration
As with many mission-critical facilities, Quadram Institute is supported by a Central Battery System (CBS). When a CBS is integrated into a DALI lighting system, it is crucial that lighting not be “held off” under DALI control when the power fails. To prevent this effect, Prolojik developed DALI phase failure monitoring units, which override the lighting to full output in the event of a lighting circuit failure.
AV integration
Prolojik’s AV gateways are installed in 9 locations to provide integration between the audio/video system and lighting control. The AV gateways support scene recall, override and bi-directional control of associated services.
HVAC integration
One of the key benefits of Prolojik’s open systems approach is the ability to directly integrate the lighting data in third-party systems such as HVAC solutions. The ability to utilize the occupancy data to achieve both lighting energy savings as well as share the data over BACnet/IP is one such benefit. This optimization halves the number of installed sensors and reduces construction costs without compromising building functionality.
EnOcean user control
EnOcean has developed a range of wireless and battery-free peripherals that are embedded into a variety of manufacturers’ devices. One example is the MK Electric Echo range of switch interfaces. EnOcean provides a number of unique benefits, including service-free operation and cable-free installation.
To take full advantage of the flexibility of EnOcean, Prolojik deployed 17 EnOcean gateways to interface with over 120 EnOcean-controlled rooms to support both switching and dimming control and data sharing with DALI multi-sensors – for seamless control integration.
IP supervisor
A building of this sophistication demanded an equally robust approach to supervision. Prolojik achieved this by implementing a TCP/IP infrastructure and virtualizing the Perspective Supervisor on a rack-mounted server located within the Quadram Institute data racks.
The Perspective Supervisor provides an extensive set of features including real-time monitoring, status reporting, system reconfiguration, time scheduling, DALI, BACnet/IP and EnOcean device management.
The Quadram Institute is a prime example of how the Prolojik open standards-based lighting control system can support the numerous demands of a sophisticated client.
