DGN/S 1.16.1 system description (group control)

The KNX/DALI Gateway DGN/S 1.16.1 with emergency lighting function is primarily a "normal" DALI Ga-
teway with group control. However, additional DALI devices for self-contained emergency lighting (device
type 1) with individual batteries compliant to the DALI standard EN 62386-202 are supported. Up to 64
DALI devices can be connected to a DALI output. DALI emergency lighting devices and normal DALI de-
vices can be combined as required. An emergency light can consist of two separate DALI devices or also
of just one individual device:
Two separate DALI devices:
1 ballast (DALI device 1) for normal lighting. It assumes the control of the lighting equipment in normal
operation.
1 emergency lighting converter (DALI device 2), which controls the lighting equipment in emergency
lighting operation. Generally, the emergency lighting converter disconnects the normal ballast in
emergency lighting operation and autonomously assumes control of the emergency lighting. The
emergency lighting converter will switch back to the normal ballast only after emergency lighting op-
eration has ended.
One DALI device:
1 combined emergency lighting converter, which assumes the control of the lighting equipment in
normal and in emergency lighting operation. Usually, they are LED based solutions.
If battery-operated emergency lighting contains two DALI devices (a ballast and a converter, each with a
DALI interface), up to 32 battery operated emergency lights can be connected. The DALI Gateway auto-
matically recognizes whether the connected DALI device is a battery operated emergency converter and
thus an emergency lighting device (device type 1) compliant to EN 62386-202. This information is indi-
cated by the DALI-Software-Tool. It is possible that both "normal" lamps as well as battery operated emer-
gency lighting are connected in a mixed configuration to the DGN/S 1.16.1. However, the maximum per-
mitted number of 64 DALI devices may not be exceeded.
Self tests of every individual emergency lighting converter is started by request via the KNX. The test re-
sult is reported via the KNX. The communication object Emergency test trigger starts the emergency light-
ing test (function test, short duration test or duration test) or queries emergency lighting tests already un-
der way. The test result is automatically sent via the 4 byte communication object Emergency test result.
Via the communication object Slave emergency active/status, all the lamps in a group controlled by the
DGN/S to the parameterized Brightness value are set. This is independent of whether the lamps them-
selves are affected by an emergency lighting operating voltage failure, mains voltage failure or DALI volt-
age failure. The response during the emergency lighting operation activated by the DALI Gateway can be
parameterized. The prerequisite is that the DGN/S is supplied by the DALI operating voltage.
The Slave emergency is not tripped by a voltage failure. It is triggered by DGN/S if a parameterised num-
ber of lamp or ballast failures exist.
Note
During emergency lighting operation, the DALI devices cannot be commissioned.
