5.1 Dual-function switch
Requirements for stairway lighting systems
The basic requirements for a stairway lighting system are as follows:
When someone is using the stairs, the stairway lights should be on.
If no one is in the stairway, the lights should go out in order to save energy.
5.1.1 Standard solution
Up to now two methods were known to control such a lighting system:
Pulse relay: When the lights are off, press any of the pushbuttons to switch on
the lights. When the lights are on, press any of the pushbuttons to switch off the
lights again.
Disadvantage: People often forget to switch off the lights
Automatic stairway light switch: Press any one of the pushbuttons to switch on
the lights. The lights switch off again automatically when a preset off delay time
has expired.
Disadvantage: You can't keep the lights switched on over an extended period of
time. The permanent on switch, usually installed inside the stairway lighting
timer unit, may be difficult or impossible to access.
The wiring is the same for both systems.
