Exploiting the DALI interface to test emergency-lighting systems

The E-touch Box from TridonicAtco is a stand-alone automatic test system for emergency lighting designed to utilise the EM Pro range of DALI emergency inverters. When integrated into a lighting system based on the DALI interface, E-touch Box provides access to the entire functionality of the DALI system — including individual addressability so that detailed information on emergency luminaires can be monitored. The system comes compete with programming software for diagnostics and a scheduler/yearly calendar. It indicates faults on lamps, control gear and batteries and can also provide information on device status, type of lamp and type of emergency unit and battery. The extensive functionality of EM Pro combined with E-touch Box offers considerable benefits for facilities managers, particularly for large lighting systems.
