Without additional hardware such as a central management system, the luminaires communicate directly with each other and with other devices including switches, dimmers and PIRs. The lighting can also be controlled by a smartphone or tablet app using the Bluetooth Low Energy wireless standard. "The project was highly versatile, with many different areas and with different requirements," says Andrew Bissell, Director of Light4/Cundall, "so we needed a solution that was easy to use, and with the ability to make necessary adjustments, as per the clients' wishes."
A unique function is in the patients' bedroom, where several sensors monitor 'out of bed' movement and alert nurses if a patient has left their bed. As is normal on projects of this type, the luminaire specification was subject to rigorous value engineering analysis. However, to the client, the selection represented clear long-term value in terms of the total cost of ownership, the reduction of disturbance to patients due to maintenance and the light quality.
