Stairwell lighting
For a conventional circuit you would need at least five space
units in the distribution board, i.e. one impulse relay, two
timing relays and two auxiliary relays.
EZ requires only four space units. A fully functioning stairwell
lighting system can be set up with five terminals and the EZ
circuit diagram.

Up to twelve such stairwell circuits can be implemented with
