The CBSD system is a central control system in DALI communications that includes an emergency lighting electrical backup central system which operates in accordance with the requirements of standard EN-50171.
The central electrical backup system provides a sinusoidal voltage of 230V 50Hz.
The central control system enables individual control of the emergency lighting fixtures in DALI communication and through the unique software it is possible to operate each emergency lighting fixture in a single-purpose or dual-purpose regime, as well as determining full or dimmed lighting intensity in normal or emergency conditions.
The central control system includes an integral single/three-phase “interchange” unit that enables to detect failures in the power supply and the lighting of emergency lighting fixtures in a period of time not exceeding 0.5 seconds.
It offers a 60 minutes emergency operation time or any time depending on client’s requirement.
The central control system enables individual control of each emergency lighting fixture, including monitoring and receiving a fault indication in the power cables, a disconnected lighting fixture, a faulty bulb, etc.
Entering lighting fixtures from two different sources:
In accordance with regulatory requirements, emergency lighting fixtures, along the escape route, will be fed from two separate supply circuits and separate electrical backup systems and in the event of a power failure, local or general, all emergency lighting will be activated along a given escape route.
The implementation of the regulatory requirement, to illuminate all emergency lighting fixtures in a given escape route, is made possible thanks to the synchronization interfaces installed in each control system and enabling the automatic activation of emergency lighting fixtures connected to the electrical backup systems installed in remote rooms.
