3.3.2 Mains failure at the main distributor (HV)
The central battery system (CB) provides DC supply voltage. The ex-
ternal DALI controller (3) is ignored, the ECG is dimmed to a previously
defined value by the monitoring module (1), which is DC compatible,
via a DALI instruction set. The emergency lighting level is pre-speci-
fied. OSRAM DALI ECGs (1) can communicate DALI and, hence, be
individually dimmed by applying a DC voltage supply.
3.3.4 DC emergency operation of the lighting system without monitoring module
The DALI controller (3) is switched off with switchover to the emer-
gency operation of the lighting system. Through the absence of the
DALI voltage (approx. 16V DC that is always present during normal
operation on the terminals of the DALI controllers), the DALI control-
lers (4) detect that the "System Failure Level" must be set.
Note:
The "System Failure Level" has priority over the Power On Level, i.e.
if the DALI voltage is absent when applying the supply voltage to the
ECG, the System Failure Level will be set.
The "System Failure Level" can be configured individually for each
ECG – from 0…100 % light.
3.3.5 QTi DALI: Benefits in emergency lighting applications
• Unrestricted DALI communication to the ECG even in emergency
operation of the lighting system
• The luminous flux factor can be freely adjusted during battery
operation and, hence, matched to the illumination situation
• Efficient utilization of the battery capacity through reduced lumi-
nous flux maintenance
• Simple installation in the luminaire
• Use of DALI ECGs as emergency lighting ECGs with unrestricted
luminance flux reduction also possible without bus
3.4 OSRAM DALI LUMINAIRE TOOL (DLT)
The OSRAM DALI LUMINAIRE TOOL (OSRAM DLT) is a testing and
programming tool for luminaries with DALI controllers. All functions
(except for the individual OSRAM serial number Chip Identification
Number (CIN)) correspond to the DALI standard and are hence ven-
dor-independent.
