The outputs L1, L2, L3 and L4 are parallel circuits to LED connections on the NIRC printed circuit
board. Each external LED must be connected between the lamp connector (L1, L2, L3 or L4) and +V
on the 6-pole connector.
Figure 54. External corridor lamp connections of the NIRC
Caution: The maximum load on each external LED circuit is 60mA.
IMPORTANT: The maximum load on each external LED circuit is 60mA.
The room controller (NIRC3) circuit board does not support an external corridor lamp directly, however
an external lamp can be connected through a green LED lamp board (NILD2-GAA) which has a
galvanically separated output with a maximum switching capacity of 0.4A at 60V peak.

See “Auxiliary Lamp Connection - NILD2” on page 52. for detailed information.

To auxiliary power supply
Max. 0.4A at 60V peak
IMPORTANT: In order to retain
the galvanic separation, it is not
allowed to connect the GND (-)
of the auxiliary power supply to
the GND (-) of the NIRC3.
