The monitoring module (2) enables the individual monitoring
and control of DALI ECGs (1).
The following applies for normal operation:
The OSRAM DALI ECG emergency lighting (1) is supplied
with AC voltage via the central battery system. All control
gears can be conventionally dimmed and are controlled by
the DALI control unit (3). For maintenance functions (e.g. for
service, switching by the maintenance supervisor), the OS-
RAM DALI ECG emergency lighting (1) can be switched via
the monitoring module (2) to 100 %; the commands of the
DALI control unit (3, e.g. dimmer setting) are ignored.
When switching the lighting system to emergency lighting
operation, two cases must be differentiated:
4.3.1 Power failure in sub-distributor (SD)
general illumination
According to DIN V VDE V 0108-100 and DIN EN 50172, if
AC mains is connected to the central battery system (CB),
the system may not be switched to battery during emer-
gency operation; however, the safety lights (1) must be
switched to continuous light. The external DALI control unit
is ignored and the OSRAM DALI ECG emergency lighting
(1) is dimmed to 100 % by the monitoring module (2) via a
DALI command set.
4.3.2 DC emergency lighting operation in the event
of power failure in the main distributor (MD)
➔ battery operation
The central battery system (CB) provides the DC supply
voltage. The external DALI control unit (3) is ignored and
the ECG is set by the monitoring module (2), which is DC-
capable, to a previously defi ned value via a DALI command
set. The emergency lighting level is specifi ed. OSRAM DALI
ECGs (1) can communicate via DALI when applying a DC
power supply and are, therefore, individually dimmable.
4.3.3 DC emergency lighting operation without addi-
tional external monitoring module (e.g.: CEAG 2L-
CG-SB) by shutting down the DALI control units
The DALI control unit (3) is switched off when converting to
the emergency lighting operation; the DALI control gears (4)
detect that the “system failure level” is set because the DA-
LI voltage (approx. 16 V DC which are always applied to the
terminals of the DALI control gears) is not available.
Note:
The “system failure level” takes priority over the “power-on
level”. In other words, if the DALI voltage is missing when
applying the mains voltage to the ECG, the “system failure
level” is set as a result. The “system failure level” can be in-
dividually set for each ECG – from 0…100 % light.
The use of OSRAM DALI control gears in emergency light-
ing management is illustrated in the following diagram.
