THE CHALLENGES

Managing both standard and emergency luminaires on the same DALI channel, requiring each DALI Controller to handle both types simultaneously

Ensuring comprehensive monitoring and control of lighting, including light levels, running hours, failures, and battery status, while executing tests for emergency lights

20 000 DALI luminaires - standard as well as emergency - and 5 000 automated sun blinds are controlled via 70 L-DALI Controllers and 35 LINX-110 Automation Servers. The challenge was that standard DALI luminaires and emergency luminaires are on the same DALI channel, so that one DALI Controller has to manage both kinds of luminaires at the same time.

Each floor contains up to 500 luminaires. Monitoring and control of standard lights comprises automatic and manual light level adjustment, time depending on profiles like occupancy, cleaning and night keeping, alarms on lamp or ballast failures and running hours. Monitoring and control of emergency lights consists of lamp value and state control, running hours in normal and emergency mode, alarms on lamp or ballast failures, battery charge status and battery failure, automatic and manual execution of function and duration tests. The benefits of monitoring the emergency lights lie in improvements of maintenance regarding battery replacement and lamp failure alarms, automatic and manual test performance and control of lamp mode state.

The L-DALI project at the Iberdrola Tower highlights significant benefits of LOYTEC‘s advanced automation solutions. The system efficiently handles both standard and emergency lighting on the same DALI channel. Key benefits include enhanced maintenance efficiency through timely alerts for lamp and ballast failures, improved safety with comprehensive emergency lighting control, optimal lighting conditions with automatic and manual adjustments, and simplified testing and control of emergency lights. LOYTEC’s solution ensures a well-maintained, safe, and efficiently illuminated environment in the Iberdrola Tower.

Iberdrola tower clearly shows that combined DALI lighting control for standard and emergency lights is feasible in a very efficient and energy-conscious way with L-DALI. Moreover, global BMS control is enabled through the applications IP channel.
