Figure 21: Circuit example of the monitoring module and OSRAM
DALI ECGs in emergency lighting management
The monitoring module (2) enables individual monitoring and control
of the DALI ECGs (1).
The following applies for normal operation:
The OSRAM DALI ECG (1) emergency lighting is supplied with AC
voltage via the central battery system. All electronic control gear can
be dimmed as usual and are controlled by the DALI controller (3).
For maintenance functions (e.g. for servicing, caretaker switching) the
OSRAM DALI ECG (1) emergency lighting can be switched to 100 %
via the monitoring module (2), the commands of the DALI controller (3)
(e.g. dimmer setting) are ignored.
A difference is now made between two cases when switching the
lighting system into emergency operation:
3.3.1 Mains failure at the subdistributor (UV)
In accordance with VDE 0108 when AC mains is present at the central
battery system (CB) in emergency operation, the system must not be
switched to battery but the security luminaires (1) must be switched to
permanent light. The external DALI controller is ignored, the OSRAM
DALI ECG (1) emergency lighting is dimmed to 100 % by the monitor-
ing module (2) using a DALI instruction set.
