Sensor Switch WSD-SA Almond Passive Infrared Programmable Semi-Automatic Vacancy Wall Switch Sensor

The WSD-SA (Semi-Automatic) Series is a Passive Infrared Wall Switch Sensor that comes factory set to be Manual On - Auto Off. It is ideal for applications where having a sensor automatically turn on lights is not desired. Instead, a simple press of the button is required to turn the lights on. It is also the ideal solution for situations where the sensor is installed in a location where it can view outside the room. This causes the sensor to trigger when a person walks by the room. The Semi-Automatic feature solves this issue by requiring the button to be pressed to turn on the lights. Besides Manual On operation, several other On Modes and Switch Modes can be programmed into the sensor using the front push-button. For rooms with obstructions the WSD-PDT-SA should be considered.
