8.1.1 Demands on Stairwell Lighting
The basic requirements for a stairwell lighting system in an
apartment block are as follows:
 When someone is using the stairs, the stairwell lights
should be on.
 If no-one is in the stairwell, the lights should go out in
order to save energy.
8.1.2 Previous Solution
Conventionally, there have been two ways to control such a
lighting system as follows:
 By means of a current impulse relay
 By means of automatic stairway lighting
The wiring for the two lighting systems is identical.
