The Stairwell Lighting Switch node operates as follows:

- When the Input connector receives a value of 1, the node sends 1 to the Output connector and starts a timer. Once the timer expires, the node sends 0 to the Output connector.

- The timer duration is determined by the Time for ON property. If the Retriggerable property is enabled, the timer restarts each time the Input connector receives a value of 1.

- If the Manual OFF property is enabled, when the Input connector switches to 0, the node immediately sends 0 to the Output connector and stops the timer. Otherwise, the timer must expire before the Output connector switches to 0.

- The Warning connector switches to 1 shortly before the timer expires, as long as the Output connector remains 1. The warning duration is defined by the Warning before OFF property.

- The ON time override property allows modification of the activation duration.

- The Time left outputs the remaining time of the timer.
