5.7.4 Auxilliary Lamp Connection
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
isolated relay contact available with a maximum switching capacity of 0.4A at 60V peak.
