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.
